[0002] Currently, split air conditioners (split units) need to install outdoor units. The function of the outdoor unit is to discharge the heat of the condenser outdoors, so that the refrigerant in the refrigeration system condenses into a liquid state.

[0003] In special scenarios, such as kitchens and bathrooms, there is no space for installing outdoor units, and it is impossible to install split air conditioners. When using integrated air conditioners (all-in-one units), such as mobile air conditioners, heat is discharged indoors during refrigeration, resulting in an overall increase in indoor temperature or the heat is dissipated outdoors through an additional exhaust duct, resulting in inconvenient installation and affecting aesthetics. Summary of the Invention

[0004] The main purpose of the embodiments of the present invention is to provide a condenser cooling device, which can use a vacuum device to reduce the pressure in the boiling heat exchange container, so that the coolant boils under the condition of being lower than the condensation temperature of the refrigerant, absorbs the heat discharged by the condenser and vaporizes into steam to carry the heat out of the room. Therefore, the air conditioner does not need to install an outdoor unit.

Detailed implementation manners

[0032] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0033] As Figure 1 shown, an embodiment of the present invention provides a condenser cooling device, including a boiling heat exchange container 1 and a pressure maintaining system.

[0034] The boiling heat exchange container 1 has an accommodating cavity 11, which is arranged for placing the condenser 93 and the cooling liquid 12. After the condenser 93 is placed in the accommodating cavity 11, its shell is immersed in the cooling liquid 12. The boiling heat exchange container 1 also has a vapor outlet, which can be arranged at the top of the boiling heat exchange container 1. The vapor outlet is communicated with the accommodating cavity 11 so that the vapor generated after the cooling liquid 12 boils can be discharged from the vapor outlet.

[0035] The pressure maintaining system includes a vacuum device 2, and the vacuum device 2 has an air inlet, which is communicated with the vapor outlet through an intake pipeline 23.

[0036] The vacuum device 2 is used to evacuate the accommodation chamber 11 to make the pressure in the accommodation chamber 11 reach the set pressure. The boiling point (boiling temperature) of the coolant 12 at the set pressure is lower than the condensation temperature of the refrigerant in the condenser 93, so as to use the coolant 12 to boil and absorb heat to cool the condenser 93. Specifically, the vacuum device 2 evacuates the accommodation chamber 11 to reduce the pressure in the accommodation chamber 11, thereby reducing the boiling point of the coolant 12 in the accommodation chamber 11. After the pressure in the accommodation chamber 11 drops to the set pressure (which can be a set pressure range), the boiling point of the coolant 12 at this set pressure can be reduced to be lower than the condensation temperature of the refrigerant in the condenser 93. In this way, the coolant 12 with a temperature difference from the condenser 93 can absorb the heat discharged from the condenser 93 and boil. The vacuum device 2 operates to maintain the pressure in the accommodation chamber 11 at the set pressure, so that the coolant 12 can continuously boil and absorb heat, so as to achieve the purpose of dissipating heat from the condenser 93 by the coolant 12 boiling and absorbing heat. The vapor generated by the coolant 12 absorbing heat and boiling can be discharged by the vacuum device 2, such as discharged outdoors.

[0037] During the boiling process of the coolant 12, the latent heat of vaporization of the coolant 12 is used to carry heat. The heat carried is large and the consumed coolant 12 is small, so that the cooling effect of the condenser 93 is good. Therefore, after the condenser 93 of the air conditioner is cooled by this condenser cooling device, the air conditioner does not need to be set as a split structure, and the condenser 93 does not need to be set in the outdoor unit, thereby reducing the requirements for the installation space of the air conditioner and improving the applicability of the air conditioner.

[0038] In some exemplary embodiments, the coolant 12 can be selected as water or an aqueous solution (formed by adding a solute to water), which has low cost, is easy to obtain, and is pollution-free. Of course, other suitable liquids can also be selected, such as other media that can boil and absorb heat.

[0039] The cooling of the condenser 93 can be carried out in three ways: air cooling, liquid water cooling, and boiling vapor cooling. Air cooling generally requires installing an outdoor unit or using a thicker exhaust duct due to the large required condensation area; liquid water cooling uses the temperature rise of water to take away the heat of the condenser 93. If the liquid water is recycled, a cooling tower is required. If the liquid water is directly discharged, the water consumption is too large; boiling vapor cooling uses the latent heat of vaporization γ of water to carry heat, and the water consumption is low.

[0040] Assume that the temperature difference of water before and after heat exchange is ΔT degrees, then

[0041] The heat Q carried by the liquid water 1 can be expressed as:

[0042] Q 1 =m 1 c p ΔT

[0043] The heat Q carried by the boiling and vaporizing water 2It can be expressed as:

[0044] Q 2 = m 2 (c p ΔT + γ)

[0045] In the formula, m 1 、m 2 is the water consumption, c p is the specific heat capacity of water at constant pressure, approximately 4.2 kJ / (kg·°C), and γ is the latent heat of vaporization of water.

[0046] If the inlet water temperature is 20°C, the outlet water temperature and the steam temperature are both 70°C, and the latent heat of vaporization γ of water at 70°C is approximately 2386 kJ / kg, then under the condition of the same heat rejection amount (i.e., Q 1 = Q 2 ), the ratio of the water consumption of liquid water and steam for heat rejection is:

[0047] m 1 :

[0048] Therefore, compared with the liquid water cooling scheme, when using the scheme of the embodiment of the present application to cool the condenser 93, the water consumption can be reduced by 12 times, which is beneficial to cost reduction; and compared with the air cooling scheme, when using the scheme of the embodiment of the present application to cool the condenser 93, the surface area of the condenser 93 can be reduced, and there is no need to set the condenser 93 outdoors, that is, there is no need to set the air conditioner as a split structure including an outdoor unit, but the air conditioner can be set as an integrated structure (i.e., an all-in-one machine) to reduce the volume of the air conditioner and the required installation space, and improve the applicability of the air conditioner.

[0049] In some exemplary embodiments, as Figure 1 shown, the pressure maintaining system further includes a pressure detecting device 3 for detecting the pressure in the accommodating chamber 11. Among them, the pressure detecting device 3 can be a pressure gauge or other pressure sensors.

[0050] The pressure detecting device 3 can detect the pressure in the accommodating chamber 11, so as to control the operation of the vacuum device 2 according to the pressure detected by the pressure detecting device 3, so that the pressure in the accommodating chamber 11 can be maintained at a set pressure, so that the boiling point of the coolant 12 can be maintained below the condensation temperature of the refrigerant, so that the coolant 12 can continuously boil and absorb heat.

[0051] In some exemplary embodiments, as Figure 1 shown, the condenser cooling device further includes a liquid level maintaining system. The liquid level maintaining system includes a liquid level detecting device 4 and a liquid supply assembly. The liquid level detecting device 4 is arranged to detect the liquid level of the coolant 12 in the accommodating chamber 11, and the liquid supply assembly is arranged to supply the coolant 12 to the accommodating chamber 11. Among them, the liquid level detecting device 4 can be a liquid level gauge or other liquid level sensors.

[0052] The liquid level detection device 4 can detect the liquid level of the coolant 12 in the accommodation chamber 11, so as to control the liquid supply assembly to supply the coolant 12 to the accommodation chamber 11 according to the liquid level detected by the liquid level detection device 4, so that the liquid level in the accommodation chamber 11 can be maintained at a set liquid level (which can be a set liquid level range). Among them, the set liquid level can be higher than the top surface of the condenser 93, so that the condenser 93 can be completely immersed in the coolant 12, ensuring the contact area between the condenser 93 and the coolant 12 and ensuring the cooling effect on the condenser 93.

[0053] It should be understood that the set liquid level is not limited to being higher than the top surface of the condenser 93, and can also be set at other heights according to needs. The function of the liquid level maintenance system is to ensure that the liquid level in the accommodation chamber 11 is maintained at the set liquid level. It is necessary to prevent the liquid level in the accommodation chamber 11 from being too low, resulting in a reduction in the contact area between the coolant 12 and the condenser 93 and poor cooling effect, and to prevent the liquid level from being too high, causing the coolant 12 to be sucked into the vacuum device 2. Therefore, there needs to be a set distance between the set liquid level and the vapor outlet at the top of the boiling heat exchange container 1.

[0054] In some exemplary embodiments, as Figure 1 shown, the boiling heat exchange container 1 further has a liquid inlet communicating with the accommodation chamber 11, and the liquid inlet can be arranged at the bottom of the boiling heat exchange container 1.

[0055] The liquid supply assembly includes a liquid inlet pipeline 51, and the outlet end of the liquid inlet pipeline 51 is communicated with the liquid inlet, so as to supply the coolant 12 from the liquid inlet to the accommodation chamber 11 through the liquid inlet pipeline 51.

[0056] The liquid supply assembly further includes a first control valve 52, and the first control valve 52 is installed in the liquid inlet pipeline 51 to control the on-off of the liquid inlet pipeline 51. Among them, the opening and closing of the first control valve 52 can be controlled according to the liquid level detected by the liquid level detection device 4, and then the connection of the liquid inlet pipeline 51 can be controlled, so as to control the supply of the coolant 12 to the accommodation chamber 11, so that the liquid level in the accommodation chamber 11 can be maintained at the set liquid level.

[0057] In some exemplary embodiments, as Figure 1 shown, the liquid supply assembly further includes a pumping device 53, and the pumping device 53 is installed in the liquid inlet pipeline 51 and is located between the first control valve 52 and the boiling heat exchange container 1. Among them, the pumping device 53 can be a water pump.

[0058] The pumping device 53 can ensure the power during the supply of the coolant 12, so that the coolant 12 can be stably supplied to the accommodation chamber 11, which is beneficial to maintaining the coolant 12 in the accommodation chamber 11 within a certain range.

[0059] It should be understood that the liquid supply assembly may also not include the pumping device 53. For example, when the coolant 12 is water or an aqueous solution and the inlet end of the liquid inlet pipeline 51 is connected to a water source with sufficient water pressure such as a faucet, the water pressure of the water source can be directly utilized to achieve liquid supply without setting up the pumping device 53.

[0060] In some exemplary embodiments, such as Figure 1 As shown, the liquid supply assembly further includes a liquid storage device 54 for storing the coolant 12, and the liquid storage device 54 is communicated with the inlet end of the liquid inlet pipeline 51.

[0061] The liquid supply assembly includes a liquid storage device 54, and the liquid storage device 54 is communicated with the accommodation cavity 11 through the liquid inlet pipeline 51, so that the coolant 12 in the liquid supply device is conveyed to the accommodation cavity 11 under the action of the pumping device 53.

[0062] It should be understood that the liquid supply assembly may also not include the liquid storage device 54. For example, when the coolant 12 is water or an aqueous solution, the water supply from the faucet can be directly utilized without setting up the liquid storage device 54.

[0063] In some exemplary embodiments, such as Figure 1 As shown, the liquid supply assembly further includes a filter 55. The filter 55 can be arranged on the liquid inlet pipeline 51, such as between the pumping device 53 and the liquid inlet, to ensure the purity of the coolant 12, prevent impurities from entering the boiling heat exchanger and causing scaling in the boiling heat exchanger, which affects the heat exchange with the condenser 93.

[0064] Such as Figure 1 As shown, the liquid supply assembly includes a liquid storage device 54, a first control valve 52, a pumping device 53 and a filter 55 that are sequentially connected through the liquid inlet pipeline 51 and are connected to the liquid inlet of the boiling heat exchange container 1. The water source for supplying water or an aqueous solution can be the liquid storage device 54 for storing water or directly utilize the faucet as the water source; whether to supply water to the boiling heat exchange container 1 is controlled by the first control valve 52 to ensure that the liquid level in the boiling heat exchange container 1 is within a certain range; if the water source is the liquid storage device 54 and the water pressure is low, then a pumping device 53 needs to be installed to ensure the power during water supply. If the water source is the faucet and the water pressure is sufficient, the pumping device 53 may not be required; the filter 55 is used to ensure the purity of the water medium, prevent impurities from entering the boiling heat exchanger and causing scaling in the boiling heat exchanger, which affects the heat exchange.

[0065] In some exemplary embodiments, the vacuum device 2 is a primary vacuum device including one vacuum device, or the vacuum device 2 is a multi-stage vacuum device including a plurality of vacuum devices connected in sequence to obtain a higher vacuum degree, so that the pressure in the accommodation cavity 11 can be reduced to the set pressure.

[0066] Such as Figure 1As shown, the vacuum device 2 is a two-stage vacuum device including two vacuum units 21a and 21b, and the vacuum units 21a and 21b can be vacuum pumps.

[0067] Of course, the vacuum device 2 is not limited to being a single-stage or two-stage vacuum device. The number of vacuum units included in the vacuum device 2 can also be adjusted according to the set pressure in the accommodation chamber 11 or the boiling point of the coolant 12. For example, the vacuum device 2 can be configured to include three or more vacuum units connected in sequence.

[0068] In some exemplary embodiments, the vacuum device 2 further includes an air ballast assembly, and the air outlet of the air ballast assembly communicates with the compression chamber of the vacuum unit.

[0069] The air ballast assembly can supply air to the compression chamber of the vacuum unit to prevent the vapor (such as water vapor) vaporized from the coolant 12 from condensing into small droplets during the compression process in the compression chamber of the vacuum unit. The small droplets can cause oil contamination of the vacuum unit or enter the high-speed rotating blades, resulting in blade damage. In addition, the supplied air can also play a certain cooling role to prevent the temperature of the vacuum unit from being too high.

[0070] In some exemplary embodiments, such as Figure 1 As shown, the air ballast assembly includes an air ballast device 61 and an air ballast valve 62. Gas channels are provided in both the air ballast device 61 and the air ballast valve 62. The air ballast device 61 is arranged between the vacuum units 21a and 21b, and the exhaust port of the vacuum unit 21a, the gas channel of the air ballast device 61, and the intake port of the vacuum unit 21b are connected in sequence. The outlet end of the gas channel of the air ballast valve 62 communicates with the gas channel of the air ballast device 61, so as to control the supply of air to the air ballast device 61 through the opening and closing of the air ballast valve 62, prevent the vapor from compressing and condensing into small droplets in the compression chamber of the vacuum unit 21b, and the supplied cold air can cool down the vacuum unit 21b.

[0071] Of course, the air ballast assembly is not limited to the Figure 1 structure shown. For example, the air ballast assembly can include only one or more air ballast valves, and the outlet end of the gas channel of each air ballast valve can communicate with the compression chamber of a vacuum unit, so as to control the supply of air to the vacuum unit through the air ballast valve.

[0072] In some exemplary embodiments, the condenser cooling device further includes a heat dissipation system, and the heat dissipation system is configured to dissipate heat from the vacuum device 2.

[0073] The vacuum device 2 needs to compress the vapor (such as water vapor) formed by the boiling of the coolant 12 from a low-pressure vacuum state to a pressure higher than 1 atmosphere to be smoothly discharged into the atmosphere. When compressing the water vapor, the temperature of the water vapor will exceed 100 °C, causing the vacuum device 2 to overheat and affecting the service life of the device. During the process of the vacuum device 2 compressing the water vapor, air is introduced through the gas ballast component to reduce the partial pressure of the water vapor and thus lower the temperature of the water vapor, which can reduce the temperature of the vacuum device 2 to a certain extent. However, this method will increase the volume and flow rate of the total compressed gas. Therefore, a heat dissipation system is set up to dissipate heat from the vacuum device 2 to reduce the temperature of the vacuum device 2 and prevent the temperature of the vacuum device 2 from being too high during operation, thereby affecting the working performance and service life.

[0074] It should be understood that other methods can also be used to cool the vacuum device. For example, other measures can be adopted to replace the gas ballast component for inter-stage cooling of the vacuum device. A certain mass of water can be sprayed between the two vacuum devices of the two-stage vacuum device to mix with the vapor, thereby reducing the inter-stage temperature of the vacuum device. However, it is necessary to ensure that the sprayed water is completely vaporized and no small liquid droplets remain to enter the next-stage vacuum device.

[0075] In some exemplary embodiments, such as Figure 2 shown, the heat dissipation system includes a refrigerant heat dissipation device. The refrigerant heat dissipation device includes a refrigerant heat dissipation branch 71 (as shown by the dotted line in Figure 2 ). One end of the refrigerant heat dissipation branch 71 is arranged to communicate with the refrigerant pipeline between the throttling mechanism 94 and the evaporator 91 in the air conditioner including the condenser 93, and the other end of the refrigerant heat dissipation branch 71 is arranged to communicate with the refrigerant pipeline between the compressor 92 and the evaporator 91 of the air conditioner. And the refrigerant heat dissipation branch 71 is arranged on the vacuum device 2. For example, the refrigerant heat dissipation pipeline 71 can be wound around the outside of the vacuum device 2.

[0076] The cooling system includes a refrigerant cooling device to utilize the refrigerant in the air conditioner to cool the vacuum device 2. Specifically, the air conditioner includes an evaporator 91, a compressor 92, a condenser 93, and a throttling mechanism 94. The evaporator 91, the compressor 92, the condenser 93, and the throttling mechanism 94 are sequentially connected through refrigerant pipelines to form a refrigerant flow path. One end of the refrigerant cooling branch 71 of the refrigerant cooling device communicates with the refrigerant pipeline between the throttling mechanism 94 and the evaporator 91, and the other end communicates with the refrigerant pipeline between the compressor 92 and the evaporator 91, that is, the refrigerant cooling branch 71 is in parallel with the refrigerant branch where the evaporator 91 is located. A refrigerant cooling branch 71 is led out from the downstream of the throttling mechanism 94 to the vacuum devices 21a and 21b, and the refrigerant cooling branch 71 is wound around the outside of the vacuum devices 21a and 21b, so that a part of the refrigerant can flow to the evaporator 91 and evaporate to absorb heat, to cool the indoor air, and another part of the refrigerant can flow to the refrigerant cooling branch 71 and evaporate to absorb heat to lower the temperature of the vacuum devices 21a and 21b (such as lowering the temperature of components such as motors and bearings in the vacuum devices 21a and 21b). The two parts of the refrigerant after temperature rise converge at the suction port of the compressor 92 and flow back to the compressor 92.

[0077] In some exemplary embodiments, such as Figure 2 shown, the cooling system further includes a second control valve 72 and a check valve 73 disposed in the refrigerant cooling branch 71. Among them, the second control valve 72 can be disposed upstream of the vacuum device 2 (that is, on the refrigerant cooling branch 71 between the throttling mechanism 94 and the vacuum device 21a), and the check valve 73 can be disposed downstream of the vacuum device 2 (that is, on the refrigerant cooling branch 71 between the vacuum device 21b and the compressor 92).

[0078] The second control valve 72 can control whether the refrigerant flows into the refrigerant cooling branch 71, that is, control whether the refrigerant cooling system starts to cool the vacuum device 2; the check valve 73 can control the flow direction of the refrigerant in the refrigerant cooling branch 71, so that the refrigerant can evaporate in the refrigerant cooling branch 71 and absorb the heat of the vacuum device 2.

[0079] It should be understood that the cooling system for cooling the vacuum device 2 is not limited to using refrigerant for cooling, and can also be other devices, such as using a fan to cool the vacuum device 2.

[0080] In some exemplary embodiments, such as Figure 2 shown, the cooling system further includes a first temperature sensor 74, and the first temperature sensor 74 is arranged to detect the temperature of the vacuum device 2.

[0081] The first temperature sensor 74 can detect the temperature of the vacuum device 2 so as to control whether the heat dissipation system is started to dissipate heat from the vacuum device 2 according to the temperature detected by the first temperature sensor 74. When the first temperature sensor 74 detects that the temperature of the vacuum device 2 is too high (higher than the set temperature), the heat dissipation system can be started to dissipate heat; when the first temperature sensor 74 detects that the temperature of the vacuum device 2 decreases (not higher than the set temperature), the heat dissipation system can be controlled to stop dissipating heat to prevent the vacuum device 2 from overheating.

[0082] In some exemplary embodiments, such as Figure 1 shown, the condenser cooling device further includes a superheater 8. The superheater 8 has a steam flow channel 81 and a refrigerant flow channel 82 therein. The intake pipe 23 communicates with the steam outlet through the steam flow channel 81, and the refrigerant flow channel 82 is arranged to communicate with the refrigerant inlet of the condenser 93.

[0083] The condenser cooling device further includes a superheater 8. The steam flow channel 81 of the superheater 8 communicates with the steam outlet of the boiling heat exchange vessel 1, and the refrigerant flow channel 82 of the superheater 8 communicates with the refrigerant inlet of the condenser 93. In this way, the steam discharged from the steam outlet of the boiling heat exchange vessel 1 can exchange heat with the refrigerant again in the superheater 8 to heat the small droplets in the steam into steam. Therefore, the setting of the superheater 8 ensures that the steam entering the vacuum device 2 is in a superheated state, preventing the small droplets in the steam from hitting the blades in the vacuum device and affecting the operation of the vacuum device.

[0084] It should be understood that not only can the superheater 8 be used to heat the small droplets in the steam into steam to eliminate the small droplets in the steam, but it can also be achieved by other means. For example, in some other exemplary embodiments, the cooling device further includes a dryer, and the dryer is arranged in the intake pipe 23. The dryer can absorb the small droplets in the steam to achieve the purpose of eliminating the small droplets in the steam.

[0085] In some exemplary embodiments, such as Figure 1 shown, the condenser cooling device further includes an exhaust pipe 24. The vacuum device 2 also has an exhaust port. One end of the exhaust pipe 24 communicates with the exhaust port, and the other end is arranged to communicate to the outside of the room.

[0086] The pressure of the exhaust port of the vacuum device 2 is greater than the atmospheric pressure, so that the steam can be smoothly discharged into the outdoor atmosphere through the exhaust pipe 24. The way of discharging into the outdoor atmosphere can be determined according to the installation conditions, such as directly discharging into the outdoor through the exhaust pipe 24, or discharging into the sewer through the exhaust pipe 24, or discharging into the flue through the exhaust pipe 24, etc.

[0087] The embodiment of the present invention also provides a condenser cooling method. Among them, such as Figure 1As shown, the condenser 93 is disposed in the accommodation chamber 11 of the boiling heat exchange container 1, and a coolant 12 is provided in the accommodation chamber 11. The pressure maintaining system is used to evacuate the accommodation chamber 11. In some exemplary embodiments, the above-described condenser cooling device can be used to cool the condenser 93.

[0088] Based on this, as Figure 3 shown, the condenser cooling method includes:

[0089] S302: Control the pressure maintaining system to evacuate the accommodation chamber so that the pressure of the accommodation chamber reaches a set pressure, and the boiling point of the coolant at this set pressure is lower than the condensation temperature of the refrigerant in the condenser, so as to cool the condenser by using the boiling endotherm of the coolant.

[0090] As Figure 1 shown, the vacuum device 2 can be used to evacuate the accommodation chamber 11 to reduce the pressure in the accommodation chamber 11, thereby reducing the boiling point of the coolant 12 in the accommodation chamber 11 until the boiling point of the coolant 12 is lower than the condensation temperature of the refrigerant in the condenser 93. At this time, the condenser 93 can be cooled by using the boiling endotherm of the coolant 12. During the boiling process of the coolant 12, the latent heat of vaporization of the coolant 12 is used to carry heat, and the heat carried is large and the coolant 12 consumed is small, so that the cooling effect of the condenser 93 is good. Therefore, after the condenser 93 of the air conditioner is cooled by using this condenser cooling device, the air conditioner does not need to be set as a split structure, and the condenser 93 does not need to be disposed in the outdoor unit, thereby reducing the requirements for the installation space of the air conditioner and improving the applicability of the air conditioner.

[0091] In some exemplary embodiments, controlling the pressure maintaining system to evacuate the accommodation chamber so that the pressure of the accommodation chamber reaches a set pressure includes:

[0092] Obtain the set pressure according to the condensation temperature;

[0093] Detect the pressure in the accommodation chamber;

[0094] Control the pressure maintaining system to evacuate the accommodation chamber according to the detected pressure so that the pressure of the accommodation chamber is maintained at the set pressure.

[0095] The condensation temperature of the refrigerant in the condenser can be obtained, and the set pressure can be obtained according to this condensation temperature. For example, the set pressure can be calculated according to the condensation temperature, or the corresponding set pressure can be obtained by querying according to the condensation temperature. As Figure 1As shown, a pressure detection device 3 can be used to detect the pressure in the accommodation chamber 11, so as to control the evacuation of the accommodation chamber 11 by the vacuum device 2 (such as the vacuum devices 21a and 21b) according to the pressure detected by the pressure detection device 3, so that the pressure in the accommodation chamber 11 can be maintained at a set pressure, so that the boiling point of the coolant 12 at this set pressure can be maintained below the condensation temperature of the refrigerant, so that the coolant 12 can continuously absorb the heat of the condenser 93 and boil.

[0096] In some exemplary embodiments, controlling the pressure maintenance system to evacuate the accommodation chamber so that the boiling point of the coolant is lower than the condensation temperature of the refrigerant in the condenser includes:

[0097] Detecting the pressure in the accommodation chamber;

[0098] Obtaining the condenser temperature of the condenser;

[0099] Controlling the pressure maintenance system to evacuate the accommodation chamber according to the detected pressure and the condenser temperature, so that the boiling point of the coolant is lower than the condensation temperature of the refrigerant in the condenser.

[0100] During the cooling process of the condenser 93, not only the pressure in the accommodation chamber 11 is detected in real time, but also the condenser temperature is obtained (such as obtaining the condenser temperature according to the temperature sensor set on the condenser 93). According to the obtained condenser temperature, the set pressure required for the accommodation chamber 11 can be obtained, and according to the detected pressure in the accommodation chamber 11, the accommodation chamber 11 is maintained at this set pressure. There is a large temperature difference between the boiling point of the coolant 12 at this set pressure and the condenser temperature, so that the coolant 12 can quickly absorb the heat of the refrigerant in the condenser 93, accelerate the cooling effect of the condenser 93, and thus improve the refrigeration effect of the air conditioner.

[0101] In some exemplary embodiments, controlling the pressure maintenance system to evacuate the accommodation chamber so that the boiling point of the coolant is lower than the condensation temperature of the refrigerant in the condenser includes:

[0102] Detecting the pressure in the accommodation chamber;

[0103] Obtaining the set temperature of the air conditioner;

[0104] Controlling the pressure maintenance system to evacuate the accommodation chamber according to the detected pressure and the set temperature, so that the boiling point of the coolant is lower than the condensation temperature of the refrigerant in the condenser.

[0105] During the cooling process of the condenser 93, not only the pressure in the accommodation chamber 11 is detected in real time, but also the set temperature of the air conditioner is obtained. The set temperature of the air conditioner can be set by the user (for example, the user sets the set temperature of the air conditioner to 20 °C, etc.). According to the obtained set temperature of the air conditioner, the condenser temperature can be indirectly obtained. According to the set temperature of the air conditioner, the set pressure of the accommodation chamber 11 can be obtained, so that there is a large temperature difference between the boiling point of the coolant 12 at this set pressure and the condenser temperature, so that the coolant 12 can quickly absorb the heat of the refrigerant in the condenser 93, accelerate the cooling effect of the condenser 93, and thus improve the refrigeration effect of the air conditioner. According to the detected pressure in the accommodation chamber 11, the operation of the pressure maintaining system can be controlled to keep the accommodation chamber 11 at this set pressure.

[0106] In some exemplary embodiments, the boiling point of the coolant at the set pressure can be lower than the condensation temperature by a preset value, where the preset value can be 2 °C - 5 °C. For example: the boiling point of the coolant at the set pressure can be 2 °C, 3 °C, 4 °C, 5 °C, etc. lower than the condensation temperature.

[0107] The boiling point of the coolant 12 at the set pressure is 2 °C - 5 °C lower than the condensation temperature, so that there is a temperature difference between the boiling point of the coolant 12 and the temperature of the refrigerant in the condenser 93, so that the coolant 12 can absorb the heat discharged from the condenser 93 and boil.

[0108] Of course, the temperature difference between the boiling point of the coolant at the set pressure and the condensation temperature is not limited to 2 °C - 5 °C, and can also be adjusted as needed. For example, the temperature difference can be less than 2 °C or greater than 5 °C.

[0109] In some exemplary embodiments, the coolant is water or an aqueous solution.

[0110] Using water or an aqueous solution as the coolant 12 has low cost, is easy to obtain, and is pollution-free. Of course, other suitable liquids can also be selected as the coolant 12.

[0111] In some exemplary embodiments, the liquid level maintaining system is used to supply coolant to the accommodation chamber 11.

[0112] Based on this, the condenser cooling method further includes:

[0113] During the process of controlling the pressure maintaining system to evacuate the accommodation chamber, the liquid level in the accommodation chamber is detected;

[0114] According to the detected liquid level, the liquid level maintaining system is controlled to supply coolant to the accommodation chamber, so that the liquid level of the coolant in the accommodation chamber is maintained at the set liquid level;

[0115] Among them, the set liquid level is higher than the top surface of the condenser.

[0116] Such as Figure 1As shown, the liquid level detection device 4 can be used to detect the liquid level of the coolant 12 in the accommodation chamber 11, and the liquid supply assembly (such as the first control valve 52 and the pumping device 53, etc.) can be controlled according to the detected liquid level to supply the coolant 12 to the accommodation chamber 11. Among them, when the liquid level is lower than the set liquid level, the liquid supply assembly is controlled to supply liquid; when the liquid level reaches the set liquid level, the liquid supply assembly is controlled to stop supplying liquid, so that the liquid level in the accommodation chamber 11 can be maintained at the set liquid level.

[0117] The set liquid level can be higher than the top surface of the condenser 93, so that the condenser 93 can be completely immersed in the coolant 12, ensuring the contact area between the condenser 93 and the coolant 12 and ensuring the cooling effect on the condenser 93; there is a set distance between the set liquid level and the vapor outlet at the top of the boiling heat exchange container 1 to prevent the liquid level from being too high and causing the coolant 12 to be sucked into the vacuum device 2. Among them, the set distance can be set according to the suction power of the vacuum device 2.

[0118] In some exemplary embodiments, the pressure maintaining system includes a vacuum device 2 for evacuating the accommodation chamber 11, and the heat dissipation system is used to dissipate heat from the vacuum device 2.

[0119] Based on this, the condenser cooling method further includes:

[0120] During the process of controlling the pressure maintaining system to evacuate the accommodation chamber, the heat dissipation system is controlled to dissipate heat from the vacuum device.

[0121] During the process of compressing the boiling vapor of the coolant 12, the temperature of the vacuum device 2 will rise, causing the vacuum device 2 to overheat. Therefore, the heat dissipation system can be used to dissipate heat from the vacuum device 2 to prevent the vacuum device 2 from overheating and thus affecting its working performance and service life.

[0122] In some exemplary embodiments, controlling the heat dissipation system to dissipate heat from the vacuum device includes:

[0123] Detecting the temperature of the vacuum device;

[0124] Controlling the heat dissipation system to dissipate heat from the vacuum device according to the detected temperature.

[0125] As Figure 2 shown, the first temperature sensor 74 can be used to detect the temperature of the vacuum device 2, and the refrigerant heat dissipation device (such as controlling the second control valve 72) can be controlled to dissipate heat from the vacuum device 2 according to the detected temperature. Among them, when the temperature of the vacuum device 2 is higher than the set temperature, the refrigerant heat dissipation device is controlled to dissipate heat; when the temperature of the vacuum device 2 is not higher than the set temperature, the refrigerant heat dissipation device is controlled to stop dissipating heat to prevent the temperature of the vacuum device 2 from being too high.

[0126] An embodiment of the present invention further provides a condenser cooling control device, including a processor, a memory, and a computer program stored on the memory and executable on the processor. When the computer program is executed by the processor, the steps of the cooling method provided in any of the above embodiments are implemented.

[0127] The processor may be an integrated circuit chip with signal processing capabilities. The above-mentioned processor may be a general-purpose processor, including a central processing unit (CPU for short), a network processor (NP for short), etc.; it may also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. It can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present invention. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc.

[0128] As Figure 1 shown, an embodiment of the present invention further provides an air conditioner, including an air conditioner main body, and the air conditioner main body includes a condenser 93. The air conditioner also includes the condenser cooling device provided in any of the above embodiments, and the condenser 93 is arranged in the accommodation cavity 11.

[0129] In some exemplary embodiments, the air conditioner also includes the above-mentioned condenser cooling control device, and the condenser cooling control device is electrically connected to the condenser cooling device. For example, the condenser cooling control device can be electrically connected to the vacuum devices 21a and 21b, the pressure detection device 3, the liquid level detection device 4, the first control valve 52, the pumping device 53, etc. of the condenser cooling device.

[0130] The air conditioner includes an air conditioner main body, a condenser cooling device, and a condenser cooling control device. The air conditioner main body is used to cool and lower the temperature of indoor air. The condenser cooling control device can be electrically connected to the condenser cooling device to control the condenser cooling device to cool the condenser 93, absorb the heat released by the refrigerant at the condenser 93, ensure the cooling effect of the condenser cooling device on the condenser 93, and further ensure the refrigeration effect of the air conditioner main body.

[0131] In some exemplary embodiments, as Figure 1 shown, the air conditioner main body further includes an evaporator 91, a compressor 92, and a throttling mechanism 94. The evaporator 91, the compressor 92, the condenser 93, and the throttling mechanism 94 are sequentially connected through a refrigerant pipeline to form a refrigerant flow path.

[0132] The composition of the air conditioner main body is similar to that of a conventional air conditioner, which consists of an evaporator 91, a compressor 92, a condenser 93, and a throttling mechanism 94 connected in sequence. The condenser 93 is located in the boiling heat exchange container 1, and the heat of the refrigerant in the air conditioner main body is dissipated into the coolant 12 in the boiling heat exchange container 1. The function of the air conditioner main body is to blow cold air into the room through the cooling air blower 95 and the cooling air duct 96 provided at the evaporator 91 to cool the user, and no heat is discharged into the room. The second temperature sensor 97 can be used to detect the temperature of the indoor air so as to control the air conditioner main body to perform refrigeration work.

[0133] In some exemplary embodiments, such as Figure 2 shown, the condenser cooling device includes a refrigerant heat dissipation device for dissipating heat from the vacuum device 2. One end of the refrigerant pipeline between the throttling mechanism 94 and the evaporator 91 is communicated with one end of the refrigerant heat dissipation branch 71, and the other end of the refrigerant pipeline between the compressor 92 and the evaporator 91 is communicated with the other end of the refrigerant heat dissipation branch 71. So that after the refrigerant discharged from the compressor 92 flows through the condenser 93 and the throttling mechanism 94, a part of it can flow to the evaporator 91 and evaporate and absorb heat to cool the indoor air, and the other part can flow to the refrigerant heat dissipation branch 71 and evaporate and absorb heat to reduce the temperature of the vacuum device 2. The two parts of the refrigerant after being heated meet at the suction port of the compressor 92 and flow back to the compressor 92. The condenser cooling control device can also be electrically connected to the second control valve 72 and the first temperature sensor 74, so as to control the opening and closing of the second control valve 72 according to the temperature of the vacuum device 2 detected by the first temperature sensor 74, and further control whether the refrigerant flows to the refrigerant heat dissipation branch 71.

[0134] Among them, the flow direction of the refrigerant in the air conditioner main body is as shown by the solid arrow of the single solid arrow in Figure 1 and Figure 2 ; the flow direction of the refrigerant in the refrigerant heat dissipation branch 71 is as shown by the dotted arrow of the single solid arrow in Figure 2 ; the flow direction of the coolant vapor in the condenser cooling device is as shown by the solid arrow of the double arrow in Figure 1 and Figure 2 ; the flow direction of the indoor air is as shown by the hollow arrow in Figure 1 and Figure 2 .

[0135] In some exemplary embodiments, the air conditioner main body is an all-in-one machine.

[0136] Since the condenser 93 is cooled by a condenser cooling device, and the latent heat of vaporization during the boiling process of the coolant 12 is used to carry heat, with a large amount of heat carried and less coolant 12 consumed, the cooling effect of the condenser 93 is good. Therefore, the condenser 93 of the air conditioner does not need to be cooled by an air-cooling method, that is, the air conditioner does not need to be set as a split-type air conditioner, and the condenser 93 does not need to be set in the outdoor unit, thereby reducing the requirements for the installation space of the air conditioner and improving the applicability of the air conditioner.

[0137] As Figure 4 shown, the embodiment of the present invention also provides a control method for an air conditioner, including:

[0138] S402: Obtain the set temperature of the air conditioner and control the main body of the air conditioner to start running;

[0139] S404: Obtain the condensation temperature of the refrigerant in the condenser;

[0140] S406: Obtain the set pressure required for the accommodation cavity according to the condensation temperature, wherein the boiling point of the coolant in the accommodation cavity under the set pressure is lower than the condensation temperature;

[0141] S408: Control the pressure maintenance system to evacuate the accommodation cavity to make the pressure of the accommodation cavity reach the set pressure, so as to cool the condenser by using the coolant to boil and absorb heat.

[0142] During the operation of the air conditioner, first obtain the set temperature set by the user and control the main body of the air conditioner to start running to achieve refrigeration. During the operation of the main body of the air conditioner, obtain the condensation temperature of the refrigerant in the condenser 93, and obtain the set pressure required for the accommodation cavity 11 of the condenser cooling device according to the condensation temperature. According to this set pressure, control the vacuum device 2 of the pressure maintenance system to work, and the vacuum device 2 evacuates the accommodation cavity 11 to make the pressure of the accommodation cavity 11 reach the set pressure. The boiling point of the coolant 12 in the accommodation cavity 11 under this set pressure is lower than the condensation temperature. Therefore, the coolant 12 can quickly absorb the heat of the refrigerant in the condenser 93 and vaporize, realizing the cooling of the condenser 93.

[0143] In some exemplary embodiments, the control method of the air conditioner further includes:

[0144] During the operation of the main body of the air conditioner, detect the current ambient temperature;

[0145] When the ambient temperature does not reach the set temperature, adjust the operating parameters of the main body of the air conditioner and the condenser cooling device;

[0146] When the ambient temperature reaches the set temperature, control the operating parameters of the main body of the air conditioner and the condenser cooling device to remain unchanged.

[0147] During the operation of the air conditioner main body, the ambient temperature is detected to determine whether the ambient temperature reaches the set temperature set by the user. When the ambient temperature does not reach the set temperature, the operating parameters of the air conditioner main body are adjusted to make the ambient temperature reach the set temperature; when the operating parameters of the air conditioner main body change, the condensation temperature changes. Correspondingly, the set pressure in the accommodation chamber 11 also changes, so that the operating parameters of the condenser cooling device also change. When the ambient temperature reaches the set temperature, the operating parameters of the air conditioner main body remain unchanged. Correspondingly, the condensation temperature also remains unchanged, and the set pressure in the accommodation chamber 11 also remains unchanged, so that the operating parameters of the condenser cooling device also remain unchanged.

[0148] In some exemplary embodiments, the control method of the air conditioner further includes:

[0149] During the operation of the air conditioner main body, the liquid level in the accommodation chamber is detected;

[0150] According to the detected liquid level, the liquid level maintenance system is controlled to supply coolant to the accommodation chamber to keep the liquid level of the coolant in the accommodation chamber at the set liquid level.

[0151] During the operation of the air conditioner main body, the coolant 12 in the accommodation chamber 11 vaporizes, causing the liquid level of the coolant 12 in the accommodation chamber 11 to decrease. Therefore, the liquid level in the accommodation chamber 11 can be detected, and the liquid level maintenance system can be controlled according to the detected liquid level to supply coolant 12 to the accommodation chamber 11 to keep the liquid level of the coolant 12 in the accommodation chamber 11 at the set liquid level, so as to efficiently cool the condenser 93.

[0152] Figure 5 A control method of an air conditioner is disclosed, including the following steps:

[0153] S502: The user sets the temperature and turns on the air conditioner for cooling;

[0154] S504: Determine whether the accommodation chamber needs to be refilled with water. If so, execute S506; if not, execute S508;

[0155] S506: Start the liquid level maintenance system to complete the water replenishment;

[0156] S508: The air conditioner main body and the condenser cooling device start to operate;

[0157] S510: Obtain the condensation temperature of the refrigerant in the condenser and calculate the set pressure required for the accommodation chamber;

[0158] S512: Determine whether the pressure in the accommodation chamber is less than the set pressure. If so, execute S514; if not, execute S516;

[0159] S514: Adjust the operating parameters of the speed regulation pressure maintenance system to make the pressure in the accommodation chamber meet the set pressure;

[0160] S516: Obtain the current environmental parameters;

[0161] S518: Determine whether the environmental temperature has reached the user - set temperature. If so, execute S522; if not, execute S520;

[0162] S518: Adjust the operating parameters of the air - conditioner main body and return to S510;

[0163] S520: The air - conditioner main body and the condenser cooling device operate stably and return to S504.

[0164] An embodiment of the present invention also provides a non - transient computer - readable storage medium, on which a computer program that can run on a processor is stored. When the computer program is executed by the processor, the steps of the cooling method provided in any of the above embodiments are implemented.

[0168] 3) A vacuum device is used to reduce the pressure in the boiling heat - exchange container, so that the coolant boils under the condition of a temperature lower than the condensation temperature in the refrigerant refrigeration cycle, and absorbs the heat discharged from the condenser;

[0169] 4) The air - conditioner does not need to install an outdoor unit, the overall volume of the machine is reduced, the required installation space is reduced, and the applicability is improved.
