[0001] The present invention relates to the technical field of air conditioning, and in particular to an anti-condensation method, an air conditioner and a computer storage medium. Background Art

[0002] Current air conditioning systems with fresh air functions present a risk of condensation during exhaust. Three main solutions exist for preventing condensation: 1. Designing two ducts, one for intake and one for exhaust, within the fresh air duct to achieve heat exchange and lower the exhaust air temperature, thus preventing condensation; 2. Installing dampers at the exhaust outlet to regulate the airflow; and 3. Incorporating diversion structures within the exhaust structure to direct condensation to specific locations.

[0003] However, for some air conditioning systems with simpler structures and plastic ducts for fresh air inlets, it is difficult to use different channels for fresh air intake and exhaust.

[0039] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The main solution of the embodiment of the present invention is: after the fresh air function of the air conditioner is turned on, it is monitored that the air conditioner enters the exhaust mode, and the current set wind speed of the air conditioner is obtained; if the current set wind speed is lower than the preset wind speed, the air conditioner is made to perform the exhaust operation alternately according to the current set wind speed and the preset wind speed; the present invention solves the condensation problem of the fresh air duct during the exhaust process, reduces the production cost of the anti-condensation setting, and improves the reliability of the air conditioner.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] Before further explaining the embodiments of the present invention in detail, the nouns and terms involved in the embodiments of the present invention are explained. The nouns and terms involved in the embodiments of the present invention are subject to the following interpretations.

[0043] Air conditioning, or air conditioner, refers to equipment that manually regulates and controls the temperature, humidity, flow rate, and other parameters of the ambient air within a building or structure. It generally consists of several components: a cooling / heating source, a cold / hot medium distribution system, a terminal unit, and other auxiliary equipment. These primarily include a refrigeration unit, a water pump, a fan, and a piping system. The terminal unit utilizes the distributed cold and heat to specifically condition the air, ensuring that the desired air parameters are met.

[0044] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. This application mainly solves the condensation problem in the air duct of the exhaust system; specifically, it can solve the condensation problem caused by air conditioning heating in cold areas; the cold area can be an outdoor environment temperature of minus 5 degrees Celsius.

[0045] The fresh air device in this application is built into the air conditioner, and can also be a separate fresh air system, which is not limited here.

[0046] Reference Figure 1 , Figure 1 Schematic diagram of the fresh air device and its fresh air function components in the air conditioner; Figure 1 As shown in a, the fresh air device 100 comprises at least: a fresh air outlet 101, a self-replaceable plug-in functional module 102, an external circulation fresh air inlet 103 and an internal circulation fresh air inlet 104; Figure 1 As shown in b, the fresh air functional component 200 includes at least a fresh air temperature and humidity sensor 201, a fresh air fan 202 and an exhaust switch door 203.

[0047] Reference Figure 2 , Figure 2 This is the first embodiment of the present application, applied to an air conditioner, and the method includes:

[0048] Step S110: After the fresh air function of the air conditioner is turned on, it is monitored that the air conditioner enters the exhaust mode, and the current set wind speed of the air conditioner is obtained.

[0049] Specifically, when the air conditioner turns on the fresh air function, it is monitored whether the air conditioner enters the exhaust mode; for example, it can be monitoring the command signal of the air conditioner remote control to turn on the fresh air function; it can also be monitoring the command signal of the fresh air function turned on issued by the air conditioner-related application in the user's mobile terminal; it can also be by identifying the user's voice command to turn on the fresh air function; the specific monitoring method is not limited here, and can be dynamically adjusted according to business needs; wherein, the exhaust mode can be that after the air conditioner turns on the fresh air function, it starts to perform exhaust operations on the indoor air.

[0050] Specifically, the currently set wind speed can be obtained by obtaining and analyzing the current operating data of the air conditioner to obtain the current set wind speed selected by the user; similarly, the currently set wind speed can be set through the air conditioner remote control, through the air conditioner-related application on the user's mobile terminal, or through the device user's voice command. In addition, the currently set wind speed can also be automatically calculated by the air conditioner based on indoor and outdoor environmental data to better meet user needs and improve user experience; wherein, the indoor environmental data may include indoor ambient temperature and indoor relative humidity; and the outdoor environmental data may include outdoor ambient temperature and outdoor relative humidity.

[0051] Step S120: If the currently set wind speed is lower than the preset wind speed, the air conditioner is caused to perform exhaust operations alternately according to the currently set wind speed and the preset wind speed.

[0052] Specifically, the currently set wind speed obtained is judged. If the currently set wind speed obtained from the user is less than the preset wind speed, the air conditioner is operated alternately according to the two exhaust modes; wherein, the two exhaust modes are alternately performed by executing the first exhaust time at the current set wind speed, and then executing the second exhaust time at the preset wind speed, and the two exhaust modes are executed alternately in a cycle until the air conditioner is monitored to leave the exhaust mode, specifically, the air conditioner may turn off the fresh air function, etc.

[0053] Specifically, the preset wind speed is greater than or equal to the current set wind speed.

[0054] Furthermore, the alternating execution of the two exhaust modes can ensure that the high wind speed is not maintained for a long time during the exhaust process, which can reduce the waste of electricity resources and thus reduce the user's usage cost. At the same time, during the exhaust process, the exhaust is carried out at the current set wind speed or the preset wind speed, changing the wind speed of the fresh air duct, increasing the wind speed of the fresh air duct, and at the same time increasing the evaporation amount of liquid water in the air in the fresh air duct, thereby destroying the conditions for condensation and preventing the formation of condensation.

[0055] In the above embodiment, the beneficial effects are as follows: by monitoring whether the air conditioner enters the exhaust mode and correctly obtaining the current set wind speed of the air conditioner, data support is provided for subsequent exhaust operations, ensuring the correctness of the judgment of the current set wind speed when performing the exhaust operation, thereby ensuring the correctness of the exhaust operation; by making the air conditioner perform the exhaust operation alternately according to the two exhaust modes, the exhaust air volume of the fresh air duct is increased, the conditions for condensation generation are destroyed, and condensation cannot be generated, thereby achieving the effect of avoiding condensation generation. This application solves the condensation problem of the fresh air duct during the exhaust process, reduces the waste of electricity and the cost of air conditioning use during the exhaust process, and improves the reliability of the air conditioner; at the same time, this application can avoid the occurrence of condensation through the fresh air fan, which is easy to implement and low in cost.

[0056] Reference Figure 3 , Figure 3 The specific implementation steps of step S120 in the first embodiment of the present application include:

[0057] Step S121: If the currently set wind speed is less than the preset wind speed, the air conditioner is caused to perform an exhaust operation according to the currently set wind speed, and a first exhaust time is monitored.

[0058] Step S122: If the first exhaust time is greater than a first time threshold, the wind speed of the air conditioner is adjusted to a preset wind speed, and a second exhaust time is monitored.

[0059] Step S123: If the second exhaust time is greater than a second time threshold, the wind speed of the air conditioner is restored to the current set wind speed to perform an exhaust operation; wherein the first time threshold is greater than the second time threshold.

[0060] Step S124: until it is monitored that the air conditioner is not in exhaust mode, the exhaust operation is stopped.

[0061] Specifically, when the outdoor ambient temperature is below -5°C, the indoor dry-bulb temperature is 20°C, and the relative humidity is 80% (the indoor air dew point is 16.35°C), and the fresh air function is turned on for more than 8 hours, the low outdoor air will flow through the fresh air duct for a long time, causing the air conditioner's exhaust pipe wall temperature to drop. If the exhaust function is turned on at this time, the air conditioner's exhaust pipe wall temperature may be lower than the indoor exhaust air's dew point temperature, and the wind speed is not high enough to meet the condensation requirements, which will cause condensation risk inside the duct. Therefore, when the exhaust function is turned on, the exhaust air volume is increased to increase the evaporation of liquid water in the air, thereby raising the inner pipe wall temperature to suppress condensation.

[0062] The steps of alternately performing the exhaust operation according to the current set wind speed and the preset wind speed include:

[0063] Step 1: If the air conditioner is monitored to enter the exhaust mode, the current set wind speed of the air conditioner is obtained and the current set wind speed is judged; at the same time, the exhaust switch door is opened and the internal circulation indoor air inlet switch door is opened.

[0064] Step 2: If the current wind speed setting is high (preset wind speed), continue to run at high speed. Otherwise, run at the current wind speed setting for a period of time t1 (first exhaust time), and determine the value of t1.

[0065] Step 3: If t1 (first exhaust time) < 30min (first time threshold), continue to operate at the currently set wind speed until t1 > 30min; if t1 (first exhaust time) > 30min (first time threshold), adjust the wind speed of the air conditioner to a high wind gear (preset wind speed) and run t2 (second exhaust time), and determine the value of t2.

[0066] Step 4: If t2 (second exhaust time) < 10min (second time threshold), continue to operate at high wind gear (preset wind speed) until t2> 10min; if t2 (second exhaust time) > 10min (second time threshold), restore the wind speed of the air conditioner to the current set wind speed, and then repeat step 3, and the current set wind speed and the preset wind speed are operated alternately at 30 minutes and 10 minutes; wherein the first time threshold is not limited to 30 minutes, and the second time threshold is not limited to 10 minutes.

[0067] By alternately exhausting air according to the current set wind speed and the preset wind speed according to the first time threshold and the second time threshold, while increasing the exhaust volume of the fresh air duct, the time that the fresh air duct remains at the preset wind speed is reduced, thereby greatly reducing the consumption of electricity resources and reducing usage costs.

[0068] Reference Figure 4 , Figure 4 The second embodiment of the anti-condensation method of the present application includes:

[0069] Step S210: After the fresh air function of the air conditioner is turned on, it is monitored that the air conditioner enters the exhaust mode, and the current set wind speed of the air conditioner is obtained.

[0070] Step S220: If the currently set wind speed is lower than the preset wind speed, the air conditioner is caused to perform exhaust operations alternately according to the currently set wind speed and the preset wind speed.

[0071] Step S230: When the currently set wind speed is equal to the preset wind speed, the exhaust operation is performed according to the preset wind speed.

[0072] Compared with the first embodiment, the second embodiment includes step S230 . Step S210 and step S220 have been described in the first embodiment and will not be repeated here.

[0073] Specifically, the current preset wind speed is judged, and if the current set wind speed is equal to the preset wind speed, the exhaust operation is performed according to the preset wind speed;

[0074] Furthermore, the preset wind speed can be the highest gear, and the exhaust is maintained at the highest gear, which greatly increases the exhaust volume of the fresh air duct and further avoids the occurrence of condensation.

[0075] Reference Figure 5 , Figure 5 The third embodiment of the anti-condensation method of the present application includes:

[0076] Step S310: After the air conditioner turns on the fresh air function, monitoring that the air conditioner enters the exhaust mode;

[0077] Step S320: Obtain the outdoor ambient temperature, the wall temperature of the exhaust pipe of the air conditioner, the indoor ambient temperature and relative humidity.

[0078] Specifically, the outdoor ambient temperature, the wall temperature of the exhaust pipe of the air conditioner, the indoor ambient temperature and the relative humidity can be obtained from a fresh air temperature and humidity sensor.

[0079] Furthermore, ambient temperature is a physical quantity that indicates the degree of heat or coldness of an environment; the indoor ambient temperature can be measured using the dry-bulb, wet-bulb, and globe methods. Relative humidity refers to the percentage of the water vapor pressure in the air to the saturated water vapor pressure at the same temperature. Alternatively, it is the ratio of the absolute humidity of moist air to the maximum absolute humidity achievable at the same temperature; it can also be expressed as the ratio of the water vapor partial pressure in moist air to the saturated pressure of water at the same temperature. The air conditioner's exhaust duct wall temperature can be the temperature of the inner wall of the fresh air exhaust duct.

[0080] Step S330: Obtaining the dew point temperature based on the indoor ambient temperature and the relative humidity.

[0081] Specifically, the temperature at which air is cooled to saturation while maintaining a constant water vapor content and pressure is called the dew point, or simply dew point, and is expressed in degrees Celsius or degrees Fahrenheit. This is essentially the temperature at which water vapor and water reach equilibrium.

[0082] Furthermore, the dew point temperature can be obtained through a temperature and humidity and dew point temperature comparison table; it can also be obtained by directly inverse calculation through the saturated water vapor pressure formula; it can also be obtained by using the conversion form of the Malagas formula; and this is not limited here.

[0083] Step S340: If the outdoor ambient temperature is lower than the preset temperature, the exhaust pipe inner wall temperature and the dew point temperature are judged.

[0084] Specifically, the preset temperature may be 15 degrees Celsius, but is not limited thereto, and may be dynamically adjusted based on the environment of the area where the air conditioner is located. That is, if the outdoor ambient temperature is lower than the preset temperature, there is a risk of condensation, and the difference between the exhaust pipe wall temperature and the dew point temperature is further determined.

[0085] It should be noted that if the outdoor ambient temperature is higher than the preset temperature, the exhaust operation is performed at the currently set wind speed. In other words, if the outdoor ambient temperature is higher than the preset temperature, indicating that the current outdoor temperature is high and there is no risk of condensation, the exhaust operation is performed at the currently set wind speed, thereby avoiding the formation of condensation and maintaining the exhaust wind speed at the currently set wind speed, thereby reducing power waste and lowering usage costs.

[0086] Step S350: If the exhaust pipe inner wall temperature is lower than the dew point temperature, the step of obtaining the current set wind speed of the air conditioner is executed.

[0087] Specifically, if the exhaust pipe inner wall temperature is lower than the dew point temperature, there is a condensation risk, and the current set wind speed of the air conditioner is further obtained, and then it is determined whether the current set wind speed is the preset wind speed.

[0088] It should be noted that if the wall temperature of the exhaust pipe is higher than the dew point temperature, there is no risk of condensation, and there is no need to increase the exhaust volume of the fresh air duct, so the exhaust operation can be performed according to the currently set wind speed.

[0089] Step S360: If the currently set wind speed is lower than the preset wind speed, the air conditioner is caused to perform exhaust operations alternately according to the currently set wind speed and the preset wind speed.

[0090] If it is equal to the preset wind speed, the preset wind speed is maintained to perform the exhaust operation. If it is less than the preset wind speed, the exhaust operation is performed by alternating the current set wind speed and the preset wind speed.

[0091] Compared with the first embodiment, the third embodiment includes step S320, step S330, step S340 and step S350. The other steps have been described in the first embodiment and will not be repeated here.

[0092] In the above embodiment, the beneficial effect is: based on the dew point temperature, the time point for increasing the exhaust volume of the fresh air duct is determined more accurately, thereby reducing the time that the fresh air duct is in a high-level exhaust position, further reducing the consumption of electricity resources and usage costs.

[0093] Reference Figure 6 , Figure 6 Another specific implementation step of step S120 in the anti-condensation method of this application includes:

[0094] Step S121': if the currently set wind speed is less than the preset wind speed, the air conditioner is caused to perform an exhaust operation according to the currently set wind speed, and a first exhaust time is monitored;

[0095] Step S122': if the first exhaust time is greater than a first time threshold, the wind speed of the air conditioner is adjusted to a preset wind speed, and a second exhaust time is monitored;

[0096] Step S123': if the second exhaust time is greater than a second time threshold, the exhaust pipe inner wall temperature and the dew point temperature are judged;

[0097] Step S124': if the wall temperature of the exhaust pipe is higher than the dew point temperature, the wind speed of the air conditioner is restored to the current set wind speed to perform the exhaust operation;

[0098] Step S125': if the exhaust pipe inner wall temperature is lower than the dew point temperature, the exhaust operation is performed according to the preset wind speed for an exhaust time of the second time threshold, and the exhaust pipe inner wall temperature and the dew point temperature are re-judged until the exhaust pipe inner wall temperature is higher than the dew point temperature.

[0099] Step S126 ′: until it is monitored that the air conditioner is not in exhaust mode, the exhaust operation is stopped.

[0100] Specifically, in this embodiment, the exhaust gear is controlled based on the dew point temperature. The specific steps are as follows:

[0101] Step 1: Monitor the air conditioner and enter exhaust mode. At this time, detect the outdoor ambient temperature T4, the exhaust pipe wall temperature T1, the indoor ambient temperature T2, and the humidity d2, and calculate the dew point temperature T3. At the same time, determine the value of the outdoor ambient temperature T4. If the outdoor ambient temperature T4 is greater than 15°C, turn on the exhaust function according to the current set wind speed. Otherwise, proceed to step 2.

[0102] Step 2: Determine the values ​​of the exhaust pipe wall temperature T1 and the dew point temperature T3. If the exhaust pipe wall temperature T1 is greater than the dew point temperature T3, start the exhaust function according to the current set wind speed. Otherwise, proceed to step 3.

[0103] Step 3: Determine whether the currently set wind speed is the preset wind speed. If the currently set gear is the high wind gear (preset wind speed), then continue to operate at the high wind gear. Otherwise, run at the currently set wind speed for a period of time t1 (the first exhaust time) and determine the value of t1;

[0104] Step 4: If t1 (first exhaust time) > 30min (first time threshold), run the windshield at high wind gear for a period of time t2 (second exhaust time), and judge the value of t2. If t2 (second exhaust time) > 10min (second time threshold), re-judge the values ​​of exhaust pipe wall temperature T1 and dew point temperature T3 until exhaust pipe wall temperature T1 > dew point temperature T3, and then exhaust at the currently set wind speed.

[0105] The second time threshold may be 10 minutes, but is not limited thereto.

[0106] In this embodiment, by combining the dew point temperature, when the exhaust pipe inner wall temperature is higher than the dew point temperature, there is no condensation risk, and exhaust is performed at the currently set wind speed; only when the exhaust pipe inner wall temperature is lower than the dew point temperature and there is a condensation risk, the preset wind speed is used to execute the preset time, and the size of the exhaust pipe inner wall temperature and the dew point temperature is re-judged to determine whether there is a condensation risk. If there is a condensation risk, the preset wind speed is continued to be maintained to perform the exhaust operation; if there is no condensation risk, the exhaust is reduced to the currently set wind speed, and the time point for executing the high wind gear is determined more accurately to avoid waste of power resources.

[0107] In one embodiment, the specific implementation steps of step S125′ in the anti-condensation method of the present application include:

[0108] If the exhaust pipe inner wall temperature is lower than the dew point temperature, a heating operation with a heating time of the second time threshold is performed on the exhaust pipe inner wall and an exhaust operation with an exhaust time of the second time threshold is performed according to the preset wind speed at the same time, and the exhaust pipe inner wall temperature and the dew point temperature are re-judged until the exhaust pipe inner wall temperature is higher than the dew point temperature.

[0109] Specifically, the second time threshold can be 10 minutes, but it is not limited here. The electric heating belt is suitable for heating and heat preservation of tanks, pipes, tanks and other containers of various industrial equipment. It is mainly composed of electric heating materials and insulating materials. The electric heating material is a nickel-chromium alloy belt, which has the characteristics of fast heating, high thermal efficiency and long service life. The insulating material is a multi-layer alkali-free glass fiber, which has good temperature resistance and reliable insulation performance. In addition, a heating film can also be applied to the exhaust pipe wall to complete the heating of the exhaust pipe wall. The specific heating film can be a resistance heating film. The resistance heating film is composed of a base film, which is usually made of plastic and printed or coated with a resistance material and has an electrical contact bus.

[0110] Specifically, an electric heating tape can be wrapped between the outer wall of the fresh air plastic duct and the insulation foam to adjust the exhaust pipe wall temperature. If the exhaust pipe wall temperature is lower than the dew point, posing a risk of condensation, the electric heating tape is heated to increase the exhaust pipe wall temperature, thereby eliminating the condensation risk. In this embodiment, the heating operation is combined with the exhaust operation to rapidly increase the exhaust pipe wall temperature, quickly eliminating the condensation risk and increasing the reliability of the air conditioner. When it is detected that the exhaust pipe wall temperature is lower than the dew point, the internal and external circulation fresh air inlets are first closed, and the electric heating tape is simultaneously heated.

[0111] The present application also protects a computer storage medium, on which an anti-condensation method program is stored. When the anti-condensation method program is executed by a processor, any of the steps of the above-mentioned anti-condensation method is implemented.

[0112] The present application also protects an air conditioner 010, comprising a memory, a processor, and an anti-condensation method program stored in the memory and executable on the processor, wherein the processor implements any of the steps of the anti-condensation method described above when executing the anti-condensation method program.

[0113] This application relates to an air conditioner 010 including Figure 7 Shown: at least one processor 012 and memory 011.

[0114] Processor 012 may be an integrated circuit chip with signal processing capabilities. During implementation, each step of the above method can be completed by hardware integrated logic circuits in processor 012 or software instructions. The above-mentioned processor 012 can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component. 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 can be a microprocessor or any conventional processor. The software module can be located in a storage medium mature in the art, such as random access memory, flash memory, read-only memory, programmable read-only memory, electrically erasable programmable memory, registers, etc. The storage medium is located in memory 011, and processor 012 reads the information in memory 011 and completes the steps of the above method in combination with its hardware.
