[0070] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0071] The present invention provides a control method for refrigeration equipment.

[0072] When existing refrigeration equipment uses CFCs and HCFCs for cooling, it emits chlorine-containing waste gas into the air and enters the atmosphere, causing ozone in the atmosphere to react with chlorine atoms, thereby destroying the ozone layer.

[0073] In this specification, the executor of the control method of the refrigeration equipment is the control device of the refrigeration equipment; the refrigeration equipment includes a water collection tank, a vacuum device, a heat exchange device and a fan; the air intake of the vacuum device is connected to the air in the water collection tank; the heat exchange device is connected to the water collection tank for heat exchange; the fan is arranged corresponding to the heat exchange device to deliver air to the heat exchange device.

[0074] To solve the above problems, refer to Figures 1 to 2 In one embodiment of the present invention, a method for controlling a refrigeration device includes:

[0075] Step S100: Controlling the vacuum device to extract the air pressure of the water collection tank according to preset operating parameters so that the heat exchange device can exchange heat with the cooled water, and controlling the fan to send the inhaled air to the heat exchange device so that the heat exchange device can send out cold air after heat exchange;

[0076] The control device of the refrigeration equipment can adjust the operating parameters of the vacuum device to preset operating parameters when the refrigeration equipment is powered on or receives a cooling start signal, so that the vacuum device can operate at the preset operating parameters and extract air from the water collection tank at a corresponding preset operating frequency, thereby reducing the air pressure in the water collection tank; the operating parameters include the operating frequency and operating voltage of the vacuum device. When the air pressure in the water collection tank decreases, the boiling point of the water stored in the water collection tank decreases and evaporates under the influence of the ambient temperature. The evaporated water vapor carries heat and is extracted by the vacuum device along with the air, thereby reducing the temperature of the remaining water in the water collection tank accordingly. The heat exchange device can be configured to be connected to cooled water; or configured to be in contact with cooled water; or configured to be in contact with cooled water through a heat conductive member, thereby achieving heat exchange with the cooled water, thereby reducing its own temperature.

[0077] The refrigeration unit's control device also adjusts the fan's operating parameters, ensuring it rotates at a preset speed and draws air into the heat exchanger, thereby driving air flow around the heat exchanger and ultimately fulfilling the refrigeration unit's air supply function. It should be noted that after the heat exchanger's temperature drops, it exchanges heat with the surrounding air, lowering the surrounding air temperature. Consequently, the fan delivers cool air.

[0078] Step S200: Acquire the ambient temperature and the set temperature, and determine the target water temperature of the water in the sump according to the ambient temperature and the set temperature;

[0079] The refrigeration equipment may be equipped with an environmental parameter sensor, such as a light sensor, a temperature sensor, or a humidity sensor, to detect environmental parameters such as light, temperature, or humidity, and output corresponding environmental parameter detection signals. The refrigeration equipment's control device may determine the current temperature of the environment in which the refrigeration equipment is located by acquiring these various environmental parameter detection signals. In some embodiments, the ambient temperature may be the outlet air temperature of the refrigeration equipment, i.e., the temperature of the air after passing through the heat exchange device.

[0080] The set temperature can be the temperature set by the user through the remote control or control panel, or the user comfort temperature called in response to the user's trigger; among them, the user comfort temperature can specifically be a preset temperature value obtained by analyzing the user's comfort before the air conditioner leaves the factory, or it can be a temperature value determined by continuously obtaining the user's set parameters during the use of the air conditioner.

[0081] It should be noted that the user comfort temperature does not refer to the set temperature of the air conditioner cooling, but can be understood as the maximum critical value of the air outlet temperature that the user can accept. The control device of the refrigeration equipment can calculate the temperature difference between the ambient temperature and the set temperature, that is, the ambient temperature difference, and can determine the temperature that the water needs to reach in order to make the current ambient temperature reach the set temperature based on the ambient temperature difference-water temperature (hereinafter referred to as "water temperature") calculation formula or the correspondence between the ambient temperature difference and the water temperature, that is, the target water temperature of the water (for simplicity, the "target water temperature of the water" will be abbreviated as "target water temperature" below). The ambient temperature difference-water temperature calculation formula and the correspondence can be obtained through preliminary experiments and will not be elaborated here.

[0082] Step S300: obtaining the current temperature of the water in the water collection tank, and adjusting the preset operating parameters of the vacuum device according to the current temperature of the water in the water collection tank and the target water temperature of the water in the water collection tank.

[0083] The water collection tank may also be provided with a temperature sensor corresponding to the water therein to detect the water temperature, so that the control device of the refrigeration equipment can obtain the current temperature of the water in the water collection tank by the temperature sensor signal output by the temperature sensor. The control device of the refrigeration equipment can perform a subtraction calculation between the current water temperature and the target water temperature to obtain the temperature difference between the two, that is, the water temperature difference, and can determine the magnitude of the required reduction in the air pressure in the water collection tank to make the current temperature of the water reach the target water temperature based on the water temperature difference-negative pressure (negative pressure: the reduction in air pressure) calculation formula or the corresponding relationship between the water temperature difference and the negative pressure. The water temperature difference-negative pressure calculation formula and the corresponding relationship can be obtained through preliminary experiments and will not be described in detail here. The control device of the refrigeration equipment can adjust the working parameters of the vacuum device according to the required reduction in the air pressure in the water collection tank, so that the vacuum device can operate with the adjusted working parameters and extract the air in the water collection tank with the corresponding operating parameters, so that the water temperature in the water collection tank can be reduced to the target water temperature, thereby making the temperature of the cold air can be reduced accordingly and meet the set temperature requirements.

[0084] In this way, the control method of the refrigeration equipment of the present invention first controls the vacuum device to extract the air pressure of the water collection tank with preset operating parameters, so that the water in the water collection tank can evaporate and cool down under the action of negative pressure and the vacuum device, and after heat exchange with the heat exchange device, controls the fan to rotate at a preset speed to first generate cold air, and then determines the target water temperature according to the ambient temperature and the set temperature, and adjusts the operating parameters of the vacuum device according to the target water temperature and the current water temperature, so that the adjusted cold air temperature can meet the set temperature requirement. This technical solution uses water as a refrigerant, so that the discharged water vapor is at a higher temperature, which does not cause any harm to the environment, and water is easy to obtain as a refrigerant, does not require complex synthesis steps, is low in cost, and is also conducive to reducing equipment costs. In actual use, this technical solution can first send cold air with a certain temperature, and then adjust the cold air temperature, so that the user's demand for cold air can be alleviated in advance, which is conducive to improving the user's usage experience.

[0085] In the existing technology, there are also technical solutions that use natural refrigerants such as hydrocarbons, ammonia, and carbon dioxide. Although natural refrigerants are derived from nature and are also harmless to the natural environment, natural refrigerants have limitations in application. For example, hydrocarbons are flammable and are currently used in small household refrigeration devices and some industrial refrigeration devices, and cannot be used in high-temperature environments; ammonia leaks pose a threat to human life and safety, so it cannot be used in household air conditioners and central air conditioning refrigeration devices; although carbon dioxide does not have flammability and toxicity problems, the pressure required for circulation is high, and the requirements for functional components are high, which is not conducive to reducing the cost of refrigeration equipment and miniaturizing and lightweighting the equipment. The cycle performance coefficient, that is, the COP value, is low. This technical solution overcomes the above-mentioned industry pain points and can be widely used in various refrigeration equipment. It does not require functional components that provide high circulation pressure. The equipment cost and volume can be reduced compared to the existing technology, which is conducive to large-scale production and application.

[0086] Reference Figures 1 to 2 In one embodiment of the present invention, step S200, obtaining the ambient temperature and the set temperature, and determining the target water temperature of the water in the sump according to the ambient temperature and the set temperature, is specifically as follows:

[0087] Acquiring an ambient temperature and a set temperature, and determining a first temperature difference between the ambient temperature and the set temperature and a temperature range within which the first temperature difference lies;

[0088] When the first temperature difference is within the first temperature range, the first preset temperature threshold is used as the target water temperature of the water in the sump;

[0089] When the first temperature difference is within the second temperature range, the difference between the first temperature difference and the second preset temperature threshold is used as the first difference, and the difference between the first preset temperature threshold and the absolute value of the first difference is used as the target water temperature of the water in the sump, and the second preset temperature threshold is the lowest temperature value in the second temperature range;

[0090] The highest temperature in the first temperature range is not greater than the lowest temperature in the second temperature range.

[0091] In this embodiment, the first temperature difference is the above-mentioned ambient temperature difference. In actual applications, the temperature range corresponding to the ambient temperature difference is limited. When the ambient temperature difference is small, the human body's perception of temperature changes is not obvious, and excessive adjustments will increase the energy consumption of the equipment. In order to solve the above problems, the present technical solution divides the temperature range corresponding to the ambient temperature difference into two temperature intervals, namely the first temperature interval and the second temperature interval. The two temperature intervals can be divided in sequence along the direction of increasing temperature to ensure that the highest temperature value in the first temperature interval is less than or equal to the lowest temperature value in the second temperature interval. The temperature range corresponding to the first temperature interval can be smaller; the temperature corresponding to the second temperature interval can be larger, or greater than the temperature range corresponding to the first temperature interval; the highest temperature in the first temperature interval and the lowest temperature in the second temperature interval can be determined by the sensitivity of the human body to temperature difference, and the lowest temperature in the first temperature interval and the highest temperature in the second temperature interval can be determined by multiple preliminary experiments, which are not limited here.

[0092] When the first temperature difference is within the first temperature interval, the control device of the refrigeration equipment can determine that the ambient temperature difference is small. At this time, the pre-stored first preset temperature threshold can be called as the target water temperature to simplify the program setting steps: wherein, the first preset temperature threshold can be determined by the target water temperature corresponding to each temperature difference in the first temperature interval measured by multiple pre-tests. When the first temperature difference is within the second temperature interval, the control device of the refrigeration equipment can determine that the ambient temperature difference is large. At this time, the first temperature difference and the second preset temperature threshold can be subtracted to obtain a first difference representing the amplitude of the first temperature difference in the second temperature interval, and the absolute value of the first preset temperature threshold and the first difference can be subtracted again to obtain a second difference, and the second difference is used as the target water temperature. In other words, when the first temperature difference is within the second interval, the target water temperature is less than or equal to the first preset temperature threshold.

[0093] With such a setting, when the ambient temperature difference is small, the first preset temperature threshold can be directly called as the target water temperature. When the ambient temperature difference is large, the target water temperature is gradually reduced as the ambient temperature difference becomes larger, so that the cold air temperature can automatically match the larger ambient temperature difference. Therefore, there is no need to conduct multiple preliminary experiments to obtain the target water temperature corresponding to each ambient temperature difference in the first temperature range and the second temperature range, which is beneficial to saving production testing costs.

[0094] Optionally, the first preset temperature threshold is selected from a range of not less than 10° C. and not more than 15° C.;

[0095] The first temperature range is not less than 0°C and not more than 2°C;

[0096] And / or, the second temperature range is not less than 2.5°C.

[0097] In actual applications, the human body is not very sensitive to temperature changes within 2°C (including 2°C), so this technical solution sets the temperature range corresponding to the first temperature interval to 2°C, so that when the first temperature difference is in the first temperature interval, the first temperature threshold is directly used as the target water temperature to simplify the program setting steps. The human body is more sensitive to temperature changes greater than or equal to 2.5°C, so this technical solution can set the temperature range corresponding to the second temperature interval to greater than or equal to 2.5°C, so that when the user is in a usage scenario with a large ambient temperature difference, the target water temperature can be quickly reduced to meet the cooling needs of the scenario. It can be seen from multiple preliminary tests that the target water temperatures corresponding to the various temperature differences in the first temperature interval are mostly within the range of greater than or equal to 10°C and less than or equal to 15°C, so a temperature value can be selected from this range, for example, the temperature value with the largest number of corresponding temperature differences is selected as the first preset temperature threshold to improve the matching degree between the first preset temperature threshold and the first temperature interval.

[0098] Optionally, the first temperature difference is no greater than 5°C.

[0099] This embodiment limits the upper limit of the first temperature difference to 5°C. In other words, if the calculated first temperature difference is greater than 5°C, 5°C is used as the first temperature difference. This configuration avoids the problem of a large first temperature difference causing the target water temperature to be too low, which in turn leads to an excessively large water temperature adjustment range. This reduces the performance requirements for functional components such as the vacuum device and the water collection tank, thereby reducing equipment costs and energy consumption.

[0100] Reference Figures 1 to 2In one embodiment of the present invention, step S300, obtaining the current temperature of the water in the sump, and adjusting the preset operating parameters of the vacuum device according to the current temperature of the water in the sump and the target water temperature of the water in the sump, specifically, adjusting the preset operating parameters of the vacuum device according to the current temperature of the water in the sump and the target water temperature of the water in the sump, are:

[0101] comparing the sum of the target water temperature of the water in the sump and the third preset temperature threshold with the current temperature of the water in the sump;

[0102] When the sum of the target water temperature of the water in the sump and the third preset temperature threshold is not less than the current temperature of the water in the sump, maintaining the operating parameters of the vacuum device;

[0103] When the sum of the target water temperature of the water in the sump and the third preset temperature threshold is less than the current temperature of the water in the sump, the operating parameters of the vacuum device are increased until the sum of the target water temperature of the water in the sump and the third preset temperature threshold is not less than the current temperature of the water in the sump.

[0104] In this embodiment, the third preset temperature threshold is an error margin threshold. The control device of the refrigeration device may add the determined target water temperature to the pre-stored third preset temperature threshold to obtain the sum of the two, and may compare the sum with the current water temperature. If the comparison result shows that the sum of the two is not less than, that is, greater than or equal to, the current water temperature, the control device of the refrigeration device may determine that the current water temperature is within a certain error and meets the cooling requirements of the current set temperature, and thus maintain the current air pressure operating parameters of the vacuum device. If the comparison result shows that the sum of the two is less than the current water temperature, the control device of the refrigeration device may determine that the current water temperature is within a certain error and cannot meet the cooling requirements of the current set temperature. In other words, the current water temperature is too high, and therefore increases the air pressure operating parameters of the vacuum device to reduce the air pressure and water temperature in the sump until the current water temperature after cooling is greater than or equal to the sum of the target water temperature and the third preset temperature threshold. This configuration allows actual errors to be taken into account when determining whether the adjusted current water temperature meets the cooling requirements, which is conducive to improving the accuracy of the determination.

[0105] Optionally, the third preset temperature threshold is not less than 1.5°C.

[0106] This technical solution limits the upper limit of the third preset temperature threshold to no more than 1.5°C so that the error margin will not be too large. The specific value can be determined based on factors such as the type, manufacturer, and actual performance of functional components such as the vacuum device and the water collection tank in the refrigeration equipment, and is not limited here. In another embodiment, when the refrigeration equipment is an air conditioner, the third preset temperature threshold can be 1.5°C. Figure 2 In the embodiment shown, 1.5 is the third preset temperature threshold, H XWis the target water temperature, H W Thus, the technical solution can be applied to refrigeration equipment of different types and manufacturers, which is conducive to improving the wide range of applications.

[0107] Reference Figures 1 to 2 In one embodiment of the present invention, the refrigeration equipment further includes a water supply device, and the water inlet of the water supply device is connected to the water collecting tank to supply water to the water collecting tank.

[0108] The control method of the refrigeration equipment further includes:

[0109] Step S400: obtaining the water level in the water collection tank;

[0110] If it is determined that the water level in the water collection tank matches the preset water level, step S100 is executed to control the vacuum device to extract the air pressure in the water collection tank according to the preset operating parameters so that the heat exchange device can exchange heat with the cooled water, and the fan is controlled to send the inhaled air to the heat exchange device so that the air is sent out as cold air after heat exchange by the heat exchange device;

[0111] A water level sensor may be provided in the water collection tank to detect the water level in the water collection tank. The control device of the refrigeration equipment can obtain the current water level in the water collection tank based on the water level sensor signal output by the water level sensor, and determine whether the current water level matches the preset water level. The control device of the refrigeration equipment can obtain the water level in the water collection tank, that is, the initial water level and the real-time water level, when the refrigeration equipment is powered on and refrigerating, and can determine whether the initial water level and the real-time water level have reached the preset water level. If so, it can be determined that they match the preset water level. When it is determined that the initial water level matches the preset water level, the control device of the refrigeration equipment can begin to execute step S100 to perform the refrigeration function; when it is determined that the real-time water level matches the preset water level, the control device of the refrigeration equipment can continue to execute the current working step to maintain the refrigeration function. If it is determined that the water level in the water collection tank does not match the preset water level.

[0112] If it is determined that the water level in the sump does not match the preset water level, for example, when the water level in the sump is lower than the preset water level, step S410 is executed to control the water supply device to supply water to the sump until the water level in the sump matches the preset water level.

[0113] If the initial water level and the real-time water level do not reach the preset water level, it can be determined that they do not match the preset water level. When it is determined that either the initial water level or the real-time water level does not match the preset water level, the control device of the refrigeration equipment can control the water supply device to inject its own stored or connected water into the water collection tank, so that the water level of the water collection tank rises to the preset water level, wherein the preset water level can be determined based on the evaporation area and is not limited here. This setting allows the initial water level and the real-time water level to always be at the preset water level, thereby solving the problem of reduced cooling effect due to insufficient initial water level and real-time water level, which is conducive to improving the stability of the cooling effect.

[0114] When the water level in the water collection tank is higher than the set water level, step S420 is executed to control the water supply device to stop supplying water to the water collection tank, and the set water level is higher than the preset water level.

[0115] The technical solution of the present invention sets the target water level for stopping water supply to a set water surface that is higher than the preset water level, so that the water level in the water collection tank can evaporate and drop from the set water level after each water supply is completed, rather than starting to drop from the preset water level. In this way, the number of water supplies during the cooling process can be effectively reduced, and the water supply device can be prevented from operating in a hiccup state (i.e., repeatedly supplying water at short intervals), which is beneficial to improving the service life of the water supply device and the cooling effect of the refrigeration equipment. In addition, the preset water level can be set to be lower than the water level corresponding to the maximum evaporation area, and the set water level can be set to be higher than the water level corresponding to the maximum evaporation area, so that the real-time water level can be near the water level corresponding to the maximum evaporation area as it evaporates, thereby improving the stability of the cooling effect.

[0116] It should be noted that step S400, step S410 and step S420 can be executed throughout the process after the refrigeration equipment is started and when the refrigeration function is performed, that is, they can be executed simultaneously with any step of the control method of the refrigeration equipment of the present invention, so as to supply water to the water collection tank in time to ensure the refrigeration effect.

[0117] Furthermore, the control method of the refrigeration equipment further includes:

[0118] Step S421, obtaining the water level change rate in the water collection tank;

[0119] Step S422: Control the speed at which the water supply device supplies water to the water collection tank according to the speed at which the water level changes.

[0120] Steps S421 and S422 may occur during the process of the water supply device supplying water to the water collection tank, that is, in step S420. Since the speed of change of the water level during water supply is affected by the shape of the water collection tank and the heat exchange device, for example, Figure 4In the illustrated embodiment, the heat exchange device includes a first heat exchanger connected to a water collection tank. The inner hole of the first heat exchanger can be a nearly circular shape, with its width first increasing and then decreasing with height. The plane on which the first heat exchanger is located is spaced a predetermined distance from the bottom surface of the water collection tank. As the water level rises with the water supply and enters the inner diameter of the first heat exchanger, the rate of water level rise decreases significantly. A large inner diameter significantly affects the time it takes for the water level to return to the level corresponding to the maximum evaporation area. Furthermore, when the water level exceeds the level corresponding to the maximum evaporation area, although the rate of water level rise increases significantly, the evaporation area actually decreases, resulting in a reduced cooling effect.

[0121] To address this issue, the technical solution of this application obtains the water level change rate, which can be the water level rise rate per unit time, and controls the water supply speed of the water supply device based on the water level change rate. Specifically, when the water level change rate is normal, the current water supply speed can be maintained; when the water level change rate decreases, the current water supply speed can be increased to increase the water level change rate, thereby reducing the time it takes to return to the water level corresponding to the maximum evaporation area; when the water level change rate increases, the current water supply speed can be reduced or even stopped to avoid a decrease in cooling effect caused by the water level far exceeding the water level corresponding to the maximum evaporation area.

[0122] Reference Figures 1 to 2 In one embodiment of the present invention, the heat exchange device includes a first heat exchanger, which is connected to a water collecting tank and is used to receive water in the water collecting tank; the air suction port of the vacuum device is connected to the air in the first heat exchanger; the water collecting tank has a first interface and a second interface; the first heat exchanger has a water inlet and a water outlet; the refrigeration equipment also includes: a first pump body, the water suction port of the first pump body is connected to the first interface of the water collecting tank, and the discharge port of the first pump body is connected to the water inlet of the first heat exchanger; and / or the refrigeration equipment also includes: a second pump body, the water suction port of the second pump body is connected to the water outlet of the first heat exchanger, and the discharge port of the second pump body is connected to the second interface of the water collecting tank.

[0123] After step S300, obtaining the current temperature of the water in the water collection tank and adjusting the operating parameters of the vacuum device according to the current temperature of the water in the water collection tank and the target water temperature of the water in the water collection tank, the method further includes:

[0124] Step S500: obtaining the operating time of the vacuum device after the refrigeration equipment reaches a preset condition, and determining whether the operating time of the vacuum device reaches the preset operating time;

[0125] The preset condition may be that the current temperature of the water in the sump matches the target water temperature of the water in the sump; or, it may be that the sum of the target water temperature of the water in the sump and the third preset temperature threshold is not less than the current temperature of the water in the sump.

[0126] In actual applications, after long periods of operation, functional components such as the vacuum device, fan, first pump body, and second pump body may experience reduced efficiency, leading to unstable cooling effects. This can be manifested in, for example, increased cold air temperature or insufficient fan speed. To address this issue, the present technical solution measures the operating time of the vacuum device after adjusting the operating parameters in step S300, and uses the timing result as the operating time of the vacuum device. The control device of the refrigeration equipment compares the obtained operating time of the vacuum device with the preset operating time to determine, based on the comparison result, whether the operating time of the vacuum device has reached the preset operating time. The preset operating time can be determined by the stable operating time of each functional component measured through multiple preliminary experiments.

[0127] If it is determined that the operating time of the vacuum device reaches the preset operating time;

[0128] Executing step S510, determining a second temperature difference between the ambient temperature and the set temperature, and adjusting at least one of an operating parameter of the vacuum device, a speed of the fan, and a speed of the first pump body and / or the second pump body according to the second temperature difference;

[0129] When the comparison result shows that the operating time of the vacuum device is greater than or equal to the preset operating time, the control device of the refrigeration equipment can determine that the preset operating time has been reached, that is, the probability of the working efficiency of each functional component decreasing at this time is low, and thus, according to the current degree of decrease in the cooling effect, for example, according to the ambient temperature difference at this time, that is, the second temperature difference, the operating parameters of the vacuum device, the speed of the fan, the speed of the first pump body and / or the speed of the second pump body, or any one or more combinations thereof can be increased so that the cooling effect of each functional component after adjustment can match the set temperature. This arrangement allows the refrigeration equipment to maintain a good cooling effect even if the components are aged, greatly extending the service life of the refrigeration equipment.

[0130] If it is determined that the operating time of the vacuum device has not reached the preset operating time, return to step S100, control the vacuum device to extract the air pressure of the water collection tank with the preset operating parameters, so that the heat exchange device can exchange heat with the cooled water, and control the fan to send the inhaled air to the heat exchange device, so as to send out cold air after heat exchange by the heat exchange device.

[0131] When the comparison result is that the operating time of the vacuum device is less than the preset operating time, the control device of the refrigeration equipment can determine that the preset operating time has not been reached, that is, the probability of the working efficiency of each functional component being reduced is low at this time, and return to execute step 300, specifically return to execute step 300: compare the sum of the target water temperature of the water in the sump and the third preset temperature threshold with the current temperature of the water in the sump, so that before the preset operating time is reached, the vacuum device can maintain or increase the current operating parameters accordingly to keep the water temperature at the target water temperature until the preset operating time is reached.

[0132] Reference Figures 1 to 2 In one embodiment of the present invention, step S510, determining a second temperature difference between the ambient temperature and the set temperature, and adjusting at least one of the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body according to the second temperature difference, specifically comprises:

[0133] determining a preset temperature range in which the second temperature difference lies;

[0134] When the second temperature difference is within the third temperature range, the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body are maintained unchanged;

[0135] When the second temperature difference is within a fourth temperature range, increasing any one or any two of the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body;

[0136] When the second temperature difference is within the fifth temperature range, increasing the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body;

[0137] The highest temperature value in the third temperature interval is not greater than the lowest temperature value in the fourth temperature interval; and the highest temperature value in the fourth temperature interval is not greater than the lowest temperature value in the fifth temperature interval.

[0138] In this embodiment, the number of preset temperature intervals corresponding to the second temperature difference is 3, namely the third temperature interval, the fourth temperature interval and the fifth temperature interval. The three temperature intervals are divided in sequence along the direction of increasing temperature to ensure that the highest temperature value in the third temperature interval is less than or equal to the lowest temperature value in the fourth temperature interval, and the highest temperature value in the fourth temperature interval is less than or equal to the lowest temperature value in the fifth temperature interval. The lowest temperature of the third temperature interval and the highest temperature of the fifth temperature interval can be determined by multiple preliminary experiments and are not limited here. In another optional embodiment, the third temperature interval may be not less than 0°C and not greater than 1°C; the fourth temperature interval is not less than 1°C and not greater than 3.5°C; and the fifth temperature interval is greater than 3.5°C. In Figure 2 In the illustrated embodiment, Δt is the second temperature difference; Δt≤Ts1: indicates that the second temperature difference is in the third temperature range; Ts1<Δt<Ts2: indicates that the second temperature difference is in the fourth temperature range; Δt≥Ts2: the first temperature difference is in the third temperature range.

[0139] In this way, when the second temperature difference is in the fifth temperature interval corresponding to a lower temperature, the control device of the refrigeration equipment can determine that the temperature difference fluctuation corresponding to the second temperature difference is small, that is, the current refrigeration effect does not decrease significantly. In other words, it can be considered that the refrigeration effect is still in a stable state, and thus the vacuum device is controlled to maintain the current operating parameters, the fan is controlled to maintain the current speed, and the first pump body and / or the second pump body is controlled to maintain the current speed, so as to avoid excessive adjustments and increased energy consumption of the refrigeration equipment. When the fourth temperature difference is in the fourth temperature interval corresponding to a normal temperature, the control device of the refrigeration equipment can determine that the temperature difference fluctuation corresponding to the second temperature difference is slightly large, and thus any one of the current operating parameters, the current fan speed, and the current speed of the first pump body and / or the second pump body can be increased, so as to avoid adjusting each functional component at the same time and increasing the energy consumption of the refrigeration equipment. When the fourth temperature difference is in the fifth temperature range corresponding to a higher temperature, the control device of the refrigeration equipment can determine that the temperature difference corresponding to the second temperature difference fluctuates greatly. At this time, the current operating parameters, the current fan speed, and the current speed of the first pump body and / or the second pump body are increased at the same time, so that the second temperature difference can be reduced in a shorter time, thereby shortening the time when the user feels that the temperature difference is too large after the refrigeration equipment has been running for a period of time and waiting for cooling, which is conducive to improving the user's usage experience.

[0140] Reference Figures 1 to 2 In one embodiment of the present invention, after determining a second temperature difference between the ambient temperature and the set temperature in step S510, and adjusting at least one of an operating parameter of the vacuum device, a speed of the fan, and a speed of the first pump and / or the second pump according to the second temperature difference, the control method of the refrigeration equipment further includes:

[0141] Step S600: Determine whether the ambient temperature matches the set temperature;

[0142] After the control device of the refrigeration equipment has adjusted the operating parameters of each functional component according to the second temperature difference, the control device of the refrigeration equipment can again obtain the adjusted ambient temperature and the set temperature before adjustment to determine whether the adjusted ambient temperature reaches the set temperature before adjustment, that is, whether the above process adjustment meets the set temperature requirements.

[0143] If the ambient temperature matches the set temperature;

[0144] Executing step S610, maintaining the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body unchanged until the water level in the water collection tank does not match the preset water level, and then executing step S410, controlling the water supply device to supply water to the water collection tank until the water level in the water collection tank matches the preset water level;

[0145] If the ambient temperature after adjustment is equal to the set temperature before adjustment or the temperature difference between the two is within the third temperature range, it can be determined that the ambient temperature matches the set temperature. At this time, the control device of the refrigeration equipment controls the vacuum device to maintain the current operating parameters, controls the fan to maintain the current speed, controls the first pump body and / or the second pump body to maintain the current speed, and controls the water supply device to replenish the water collection tank in real time to reduce the water level drop caused by evaporation. There is no need to make too many adjustments to save equipment energy consumption.

[0146] If the ambient temperature does not match the set temperature, step S510 is executed to determine a second temperature difference between the ambient temperature and the set temperature, and at least one of the operating parameters of the vacuum device, the speed of the fan, and the speed of the first pump body and / or the second pump body is adjusted according to the second temperature difference.

[0147] If the adjusted ambient temperature is not equal to the pre-adjustment set temperature, or if the temperature difference between the two is significant, the cooling device's control device may determine that the adjusted ambient temperature has not reached the pre-adjustment set temperature, indicating that the adjustment process is ineffective. In this case, the cooling device's control device may calculate a second temperature difference based on the newly acquired ambient temperature and the set temperature, and then adjust the operating parameters of each functional component again according to step S510. This technical solution, by confirming the adjustment effect after each adjustment based on the second temperature difference, forms a closed-loop feedback loop, thereby improving the stability of the cooling effect during the cooling process and enhancing the user experience.

[0148] Reference Figures 1 to 2 In one embodiment of the present invention, the preset running time is selected from a range of not less than 5 minutes and not more than 30 minutes.

[0149] Numerous experiments have shown that the time period between 5 and 30 minutes after the cooling condition of refrigeration equipment such as air conditioners stabilizes is a time period during which the working efficiency of functional components such as the vacuum device, fan, first pump body, and second pump body is easily reduced. Therefore, the preset operating time of this application can be selected from a range of greater than or equal to 5 minutes and less than or equal to 30 minutes. For example, the operating time during which the cooling efficiency decreases the most can be selected as the preset operating time. The specific selection can be determined based on the type and manufacturer of different refrigeration equipment and is not limited here. In this way, the present technical solution can be applied to refrigeration equipment of different types and manufacturers, which is conducive to increasing the breadth of application.

[0169] The present invention also provides a refrigeration device, which can be used in refrigeration appliances such as air conditioners to constitute a functional component for refrigeration on the refrigeration appliance; or, the refrigeration device can be directly used as a refrigeration appliance such as an air conditioner.

[0170] See also Figures 4 to 6 The accompanying drawings illustrate specific embodiments of the refrigeration equipment provided by the present invention. For ease of understanding, the following embodiments are described using an air conditioner as an example. The air conditioner can be an integrated air conditioner or a split air conditioner. Specifically, when the air conditioner is an integrated air conditioner, it can be a portable air conditioner or a window air conditioner. When the air conditioner is a split air conditioner, it can be a wall-mounted air conditioner, a ceiling-mounted air conditioner, or a floor-standing air conditioner.

[0171] Reference Figures 4 to 6 In one embodiment of the present invention, the refrigeration device includes:

[0172] Water collecting tank 200;

[0173] A vacuum device 300, wherein the air inlet 310 of the vacuum device 300 is connected to the air in the water collecting tank 200, and the vacuum device 300 is used to extract the gas in the water collecting tank 200;

[0174] The heat exchange device 400 is connected to the water collecting tank 200 for heat exchange; and

[0175] A fan 500 is provided corresponding to the heat exchange device 400 to deliver air to the heat exchange device 400;

[0176] The control device of the refrigeration equipment is electrically connected to the vacuum device 300 and the fan 500. The specific structure of the control device of the refrigeration equipment is similar to the above-mentioned embodiments. Since the present refrigeration equipment adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0177] In the technical solution provided by the present invention, under the action of the vacuum device 300, the air pressure in the water collecting tank 200 and / or the heat exchange device 400 is reduced and the air flow rate is increased, so that the water in the water collecting tank 200 and / or the heat exchange device 400 evaporates and absorbs heat and cools the environment in which the heat exchange device 400 is located; the fan 500 blows the cooling airflow generated by the side of the heat exchange device 400 to the air duct 110, thereby cooling the air passing through the air duct 110; compared with chlorofluorocarbon refrigerants, the evaporative cooling of water is non-toxic and harmless to the environment and users, is easy to use, and has a high energy efficiency ratio.

[0178] The refrigeration equipment may also include a housing, which may be configured to a desired shape, size, and material, depending on actual needs. For example, if the air conditioner is a wall-mounted unit, the housing may be substantially horizontally elongated; alternatively, if the air conditioner is a floor-standing unit, the housing may have a cross-sectional shape that is circular, elliptical, polygonal, or other shapes, without limitation. The housing may be formed with an air duct 110, which generally includes at least one air inlet and at least one air outlet, allowing air to enter through the air inlet, flow through the air duct 110, and be discharged through the air outlet. The air outlet is generally used to connect to the indoor environment. Since the specific type of air conditioner is not limited, in actual application, the air duct 110 can be a conventional heat exchange air duct 110, with an air inlet used to connect to the indoor environment and introduce indoor air into the heat exchange air duct 110; the air duct 110 can also be a fresh air duct 110, with an air inlet used to connect to the outdoor environment and introduce outdoor fresh air into the heat exchange air duct 110; of course, the air duct 110 can also be specifically manifested as a purification air duct 110 or an aromatherapy air duct 110, etc., the purification air duct 110 is internally provided with a purification device such as an ultraviolet light generator, and the aromatherapy air duct 110 is internally provided with the desired aromatherapy product. It is understood that any air duct 110 structure that requires a certain degree of cooling of the gas flowing through it is within the protection scope of the air duct 110 of this design.

[0179] Functional components such as the water collection tank 200, vacuum device 300, heat exchange device 400, and fan 500 can be directly disposed within the air duct 110. Alternatively, in one embodiment, the housing further comprises a heat exchange chamber that is in communication with the air duct 110. At least a portion of the functional components such as the water collection tank 200, vacuum device 300, heat exchange device 400, and fan 500 can be disposed within the heat exchange chamber, with at least the heat exchange device 400 and fan 500 disposed adjacent to the air duct 110.

[0180] The water collection tank 200 is used to store an appropriate amount of water. The water can be tap water or other liquids suitable for evaporative cooling. To ensure timely replenishment of the water stored in the water collection tank 200, in one embodiment, the refrigeration equipment further includes a water supply device 800. The water supply device 800 has a water inlet 811 that is connected to the water collection tank 200. The water supply device 800 can be manually operated by the user to provide water, or it can be electrically connected to the aforementioned control device to enable automatic water supply under the control of the control device.

[0181] The water supply device 800 can be integrated with the water collection tank 200. For example, a through hole is provided through the wall of the water collection tank 200, and the through hole directly constitutes the water injection port 811. When the through hole is provided above the water collection tank 200, external water can directly enter the water collection tank 200 through the water injection port 811 under the action of gravity.

[0182] The water supply device 800 can also be set separately from the water collecting tank 200. For example, the tank wall of the water collecting tank 200 is penetrated with a through hole. The water supply device 800 includes a water supply pipe 810, which is passed through the through hole and installed on the water collecting tank 200. Any pipe opening of the water supply pipe 810 constitutes a water inlet 811.

[0183] In view of the above, when the position of the water inlet 811 is adjusted, external water can automatically enter the water collection tank 200 under the action of gravity. Alternatively, as in this embodiment, the water supply device 800 also includes a fifth pump body 820, which is installed in the water supply pipeline 810 and is electrically connected to the control device. Specifically, under the control of the control device, the third water pump can drive the water in the water supply pipeline 810 to flow toward the water collection tank 200, thereby achieving rapid water filling of the water collection tank 200 in any installation orientation.

[0184] Furthermore, based on any of the above embodiments, the water supply device 800 further includes a shutoff valve 830, which is disposed in the water supply line 810 and is electrically connected to the control device. The shutoff valve 830 can be activated under the control of the control device to intercept water passing through the water supply line 810, thereby preventing external water from unintentionally entering the water collection tank 200 or preventing water from flowing out of the water collection tank 200. The shutoff valve 830 can also be closed under the control of the control device to allow water to flow freely.

[0185] In addition, based on any of the above embodiments, the water supply device 800 further includes a water storage tank 840, which is connected to the water supply pipeline 810. The water storage tank 840 can be disposed inside the housing or outside the housing. The water storage tank 840 can store a certain amount of water for backup use in the water collection tank 200, thereby preventing the refrigeration equipment from failing to obtain the required amount of water due to the water collection tank 200.

[0186] Due to the random motion and collisions of molecules, at any given moment, some molecules possess kinetic energy greater than the average. When these molecules possess sufficiently high kinetic energy, exceeding the work required to overcome the intermolecular attraction within the liquid, they can escape from the liquid surface and evaporate into a gaseous state. During evaporation, molecules with greater kinetic energy than the average escape, while the average kinetic energy of the molecules remaining within the liquid decreases. Therefore, during evaporation, if no external energy is added to the liquid, its temperature will drop, requiring it to absorb heat from surrounding objects through heat transfer, thereby cooling them.

[0187] This design primarily utilizes a vacuum device 300 to achieve heat absorption through evaporation of water. Specifically, the vacuum device 300 is used to extract air from the water collection tank 200 and / or heat exchange device 400, thereby reducing the air pressure within the water collection tank 200 and / or heat exchange device 400 and accelerating the circulation of air within the water collection tank 200 and / or heat exchange device 400.

[0188] Liquid and air regions are generally formed within the water collection tank 200 and / or the heat exchange device 400. When the air pressure within the vacuum chamber decreases and the air flows, it provides power to the high-kinetic-energy molecules, promoting their detachment from the liquid surface and their rise into the air region, thereby achieving rapid evaporation.

[0189] For ease of understanding, in the following embodiments, a chamber capable of performing evaporation under the action of the vacuum device 300 is defined as a vacuum chamber. Since the water collection tank 200 and / or the heat exchange device 400 can both perform evaporation under the action of the vacuum device 300, the water collection tank 200 and / or the heat exchange device 400 can both define a vacuum chamber.

[0190] The specific form of the vacuum device 300 is not limited, and may be, for example, a suction pump of any type. The vacuum device 300 generally includes a device body, which is electrically connected to a control device. Under the control of the control device, the vacuum device 300 can be activated, deactivated, and the pumping speed can be adjusted. Adjusting the pumping speed of the vacuum device 300 can adjust the degree of evaporation in the sump 200 and / or heat exchange device 400 connected to the vacuum device 300, thereby adjusting the cooling capacity.

[0191] The device body has an air intake port 310, which communicates with the air collection tank and / or the heat exchange device 400. The device body also has an exhaust port 320, which is used to communicate with the external environment or other functional components of the air conditioner. Under the control of the control device, exhaust gas generated in the water collection tank 200 and / or the heat exchange device 400 connected to the vacuum device 300 is discharged through the exhaust port 320. The exhaust gas can be hot gas generated after heat exchange or excess gas.

[0192] In view of the above, the heat exchange device 400 is disposed within the air duct 110 or adjacent to the air duct 110 to perform heat exchange on the air passing through the air duct 110. There are various specific embodiments of the heat exchange device 400 (for ease of understanding, in the following embodiments, the water in the sump 200 and / or the heat exchange device 400 that has not been evaporated is defined as room temperature water, and the water that has been evaporated is defined as chilled water):

[0193] See also Figure 4 In the first embodiment of the refrigeration device, the heat exchange device 400 includes a first heat exchanger 410, which is in communication with the water collecting tank 200 to receive water in the water collecting tank 200 for heat exchange;

[0194] The air intake port 310 of the vacuum device 300 is in communication with the air in the first heat exchanger 410 .

[0195] In this embodiment, the water collection tank 200 provides a sufficient amount of room-temperature water to the first heat exchanger 410. The air intake 310 of the vacuum device 300 can be directly connected to the air in the first heat exchanger 410, or indirectly connected to the air in the first heat exchanger 410 through the water collection tank 200, so that the interior of the first heat exchanger 410 forms a vacuum chamber. Evaporation occurs directly in the first heat exchanger 410. During the evaporation process, the first heat exchanger 410 absorbs heat from the outside through its shell wall, causing the temperature in the area where the first heat exchanger 410 is located to decrease, generating refrigerated air.

[0196] Furthermore, in one embodiment of the present invention, the first heat exchanger (410) includes a heat exchange tube (401), the inner diameter of the heat exchange tube (401) is D, and when the refrigeration equipment is working, the water level in the heat exchange tube (401) is not lower than 0.25D, and the water level in the heat exchange tube (401) is not higher than 0.75D.

[0197] The water collecting tank 200 may further have a bottom surface; the plane where the first heat exchanger 410 is located is arranged parallel to the bottom surface of the water collecting tank 200 and is a first preset distance S1 away from the bottom surface of the water collecting tank 200. The first heat exchanger 410 is provided with a heat exchange tube 401, and the inner hole of the heat exchange tube 401 has a height H in the first preset direction. The first preset direction is a direction perpendicular to the plane where the first heat exchanger 410 is located.

[0198] The preset water level is S1+S2, and S2 is selected from the range of not less than 0.25H and not more than 0.75H.

[0199] It can be understood that since the plane of the first heat exchanger 410 is parallel to the bottom surface of the sump 200, the height H of the inner hole of the heat exchange tube 401 is referenced to the plane of the first heat exchanger 410. Therefore, when the preset water level is set to S1 + H, the amount of water supplied to the first heat exchanger 410 just fills the entire heat exchange tube 401 of the first heat exchanger 410. The vacuum chamber defined within the first heat exchanger 410 forms only a liquid area, without any air area. Even if the vacuum device 300 is connected to the first heat exchanger 410, evaporation cannot occur within the first heat exchanger 410. When the preset water level is high, the liquid area of ​​the vacuum chamber within the heat exchanger expands while the air area shrinks, reducing the evaporation area within the vacuum chamber and lowering evaporation efficiency. Conversely, when the preset water level is low, the air area of ​​the vacuum chamber within the heat exchanger expands while the liquid area shrinks. Although sufficient evaporation area is created, insufficient water is provided for evaporation, similarly lowering evaporation efficiency. Therefore, the preset water level needs to be set within an appropriate range. After design, the preset water level is set to S1+S2, and S2 is selected from the range of not less than 0.25H and not more than 0.75H, which helps the first heat exchanger 410 to perform efficient evaporation and heat absorption and achieve better heat exchange effect.

[0200] Furthermore, in one embodiment of the present invention, when the refrigeration device is operating, the ratio of the volume of water in the water collecting tank (200) to the volume of air in the water collecting tank (200) is not less than 1 and not greater than 2.5.

[0201] The water collecting tank 200 may also have a top surface; in the water collecting tank 200, the volume between the plane where the preset water level is located and the top surface of the water collecting tank 200 is the first volume, and the volume between the plane where the preset water level is located and the bottom surface of the water collecting tank 200 is the second volume, and the ratio of the second volume to the first volume is not less than 1 and not greater than 2.5.

[0202] It can be understood that the preset water level is equivalent to defining the effective water storage level within the sump 200. Since, in the second embodiment described above, the sump 200 constitutes a vacuum chamber, similarly to the above, when the preset water level is high, the liquid area of ​​the vacuum chamber will be expanded but the air area will be reduced, reducing the evaporation area within the vacuum chamber and lowering the evaporation efficiency. Conversely, when the preset water level is low, the air area of ​​the vacuum chamber will be expanded but the liquid area will be reduced. Although sufficient evaporation area is formed, insufficient water can be provided for evaporation, similarly lowering the evaporation efficiency. Therefore, by design, the ratio of the second volume to the first volume is set to be no less than 1 and no greater than 2.5, which facilitates efficient evaporation and heat absorption in the sump 200, thereby providing sufficient chilled water for the second heat exchanger 420 and achieving a better heat exchange effect.

[0203] Further, in one embodiment of the present invention, please refer to Figure 5 The water collecting tank 200 has a first interface and a second interface; the second heat exchanger 420 has a water inlet and a water outlet;

[0204] Refrigeration equipment also includes:

[0205] a first pump body 710, wherein the water suction port of the first pump body 710 is connected to the first interface of the water collecting tank 200, and the discharge port of the first pump body 710 is connected to the water inlet of the second heat exchanger 420;

[0206] And / or, the refrigeration equipment further comprises:

[0207] The second pump body 720 , the water suction port of the second pump body 720 is communicated with the water outlet of the second heat exchanger 420 , and the discharge port of the second pump body 720 is communicated with the second interface of the water collecting tank 200 .

[0208] It is understood that the water collection tank 200 can be set vertically or horizontally. When it is set vertically, the cooling water therein can enter the second heat exchanger 420 under the action of gravity, but the chilled water cannot circulate within the second heat exchanger 420. Therefore, in this embodiment, the water inlet and water outlet of the heat exchange tube 401 of the second heat exchanger 420 are connected to the first and second interfaces of the water collection tank 200 respectively. The first pump body 710 can drive the lower-temperature chilled water through the first interface of the water collection tank 200 and into the second heat exchanger 420 from the water inlet of the heat exchange tube 401. After heat exchange with the surrounding environment in the second heat exchanger 420, it becomes higher-temperature chilled water. The first pump body 710 can drive the higher-temperature chilled water back to the water collection tank 200 from the water outlet of the heat exchange tube 401 and the second interface of the water collection tank 200 to continue evaporation and heat absorption. In this way, both configurations of the water collection tank 200 can be met. The rotational speed of the first pump 710 regulates the flow rate of chilled water circulating between the water collection tank 200 and the second heat exchanger 420. Since the function and operating principle of the second pump 720 are similar to those of the first pump 710, they are not described here. The second pump 720 is disposed between the water outlet of the second heat exchanger 420 and the second interface of the water collection tank 200.

[0209] See also Figure 5 In the second embodiment of the refrigeration device, the heat exchange device 400 includes a second heat exchanger 420, and the second heat exchanger 420 is connected to the water collecting tank 200 to receive the chilled water generated in the water collecting tank 200 after evaporation and cooling by the vacuum device 300;

[0210] The air inlet 310 of the vacuum device 300 is in communication with the air in the sump 200 .

[0211] In this embodiment, a sufficient amount of room-temperature water is stored in the water collection tank 200. The air intake 310 of the vacuum device 300 is connected to the water collection tank 200, forming a vacuum chamber. Under the action of the vacuum device 300, the room-temperature water in the water collection tank 200 is converted into chilled water through evaporation. The water collection tank 200 is connected to the second heat exchanger 420, and the chilled water can flow through the second heat exchanger 420, reducing the internal temperature of the second heat exchanger 420. The heat is absorbed from the outside through the shell wall of the second heat exchanger 420, thereby reducing the temperature in the area where the second heat exchanger 420 is located, generating refrigerated air.

[0212] See also Figure 6 In the third embodiment of the refrigeration device, the heat exchange device 400 includes a third heat exchanger 430 disposed in the water collecting tank 200 and a fourth heat exchanger 440 disposed outside the water collecting tank 200. The two ends of the third heat exchanger 430 are respectively connected to the two ends of the fourth heat exchanger 440 in a one-to-one manner.

[0213] The fan 500 is provided corresponding to the fourth heat exchanger 440 .

[0214] In this embodiment, the two ends of the third heat exchanger 430 are connected one-to-one with the two ends of the fourth heat exchanger 440, forming a closed annular flow path between the third heat exchanger 430 and the fourth heat exchanger 440. A heat exchange medium can then be injected into the third heat exchanger 430 and the fourth heat exchanger 440. This heat exchange medium can be a material with high thermal conductivity, but the specific embodiment is not limited thereto. For example, it can be a solid material such as metal fiber, a gaseous material such as air, or a fluid material such as various refrigerant solvents.

[0215] A sufficient amount of room-temperature water is stored in the water collection tank 200. The air intake 310 of the vacuum device 300 is connected to the water collection tank 200, forming a vacuum chamber. Under the action of the vacuum device 300, the room-temperature water in the water collection tank 200 is converted into chilled water through evaporation. The third heat exchanger 430 is located in the water collection tank 200. After exchanging heat with the chilled water in the water collection tank 200, it transfers the cooling energy to the fourth heat exchanger 440. The fourth heat exchanger 440 absorbs heat from the outside through its shell, reducing the temperature in the area and generating refrigerated air.

[0216] Of course, the third heat exchanger 430 can also be configured to be connected to the water collection tank 200, connected to the chilled water in the water collection tank 200, and at the same time receive the cooling effect of the chilled water in the water collection tank 200, which also helps to improve the heat exchange effect; the fourth heat exchanger 440 can also be configured to be connected to the environment. At this time, when the fan 500 guides the air flow, part of the air can enter the fourth heat exchanger 440, so that the air constitutes the above-mentioned heat exchange medium.

[0217] Similar to the configuration of the first pump body 710 and / or the second pump body 720 described above, the refrigeration equipment further includes a third pump body 730 and / or a fourth pump body 740. The configuration of the third pump body 730 can be similar to that of the first pump body 710, i.e., it is disposed between the water outlet of the third heat exchanger 430 and the water inlet of the fourth heat exchanger 440 to drive the heat exchange medium to circulate between the third heat exchanger 430 and the fourth heat exchanger 440. It is understood that the third pump body 730 can drive the heat exchange medium with a lower temperature at the third heat exchanger 430 into the fourth heat exchanger 440. After the fourth heat exchanger 440 exchanges heat with the surrounding environment, the heat exchange medium with a higher temperature is formed. The third pump body 730 can then drive the heat exchange medium with a higher temperature from the fourth heat exchanger 440 back to the third heat exchanger 430, so that the heat exchange medium in the third heat exchanger 430 continues to cool down in the sump 200. The rotational speed of the second pump body 720 can be adjusted to adjust the circulation flow rate of the heat exchange medium between the third heat exchanger 430 and the fourth heat exchanger 440. The fourth pump body 740 can be arranged similarly to the second pump body 720, that is, it is arranged between the water inlet of the third heat exchanger 430 and the water outlet of the fourth heat exchanger 440, and will not be further described here.

[0218] It should be noted that, in any of the above embodiments, there is no limitation on the specific form of the heat exchange tube 401. The heat exchange tube 401 can be set to any suitable shape, size, material, etc. For example, Figures 1 to 3 In the embodiment, the heat exchange tube 401 has two ports arranged opposite to each other, and the heat exchange tube 401 includes a straight pipe section respectively connected to the two ports, and a bent pipe section located between the two straight pipe sections and respectively connected to the two straight pipe sections, and the bent pipe section is formed by at least one bend.

[0219] In addition, according to actual needs, the above-mentioned first to third embodiments can be combined, for example, the solution of the first embodiment can be combined with the solution of the second embodiment to further improve the cooling effect, which will not be described in detail here.

[0220] The fan 500 is provided in correspondence with the heat exchange device 400. Based on the above, it can be seen that the heat exchange device 400 can reduce the temperature in the area in which it is located and generate cooling air. The function of the fan 500 is to blow the cooling air into the air duct 110 so that the cooling air can cool the air in the air duct 110 in a timely manner. When the heat exchange device 400 is provided outside the air duct 110, the fan 500 can be provided on the side of the heat exchange device 400 facing away from the air inlet of the air duct 110 to blow the cooling air into the air duct 110; the fan 500 can also be provided on the side of the heat exchange device 400 close to the air inlet of the air duct 110 to draw the cooling air into the air duct 110. The rotation speed of the fan 500 can be used to adjust the flow rate of the cooling air entering the air duct 110 from the heat exchange device 400.

[0221] In the above embodiment, the refrigeration device further includes a water level sensor 600 . The water level sensor 600 is disposed in the water collection tank 200 and is electrically connected to the control device. The water level sensor 600 is used to sense the water level in the water collection tank 200 .

[0222] The control device is also electrically connected to the water supply device 800. Under the control of the control device, the water level sensor 600 senses the water level in the sump 200 in real time and generates a sensing signal when the water level falls below or rises above a preset level. The sensing signal is then transmitted to the control device. For example, when the water level in the sump 200 is below the preset level, the control device controls the water supply device 800 to start supplying water based on the received sensing signal. When the water level in the sump 200 is above the preset level, the control device controls the water supply device 800 to stop supplying water based on the received sensing signal.

[0223] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
