Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a control method for preventing condensation of an air conditioner, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the control method for preventing condensation of the air conditioner.
While a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different sequence than that shown or described herein.
The control method for preventing condensation of the air conditioner comprises the following steps:
and step S10, acquiring the air temperature and the air humidity corresponding to the power module in the air conditioner, and acquiring the coil temperature of the heat dissipation coil corresponding to the power module.
Referring to fig. 2, in a heat dissipation system diagram of a power module 161 of an air conditioner, a throttle part compressor 110 is connected to a condenser 120 and an evaporator 130, the throttle part includes a first throttle part 140 and a second throttle part 150, the condenser 120 is connected to the first throttle part 140, the evaporator 130 is connected to the second throttle part 150, and the power module 161 is connected to the first throttle part 140 and the second throttle part 150. The compressor 110 is a power of an air conditioner, in the air conditioner, the purpose of the compressor 110 is to compress low-temperature gas into high-temperature gas through the compressor 110, and finally the gas exchanges heat with other media in a heat exchanger. The condenser 120 cools the high-temperature and high-pressure refrigerant superheated vapor discharged from the compressor 110 into a liquid or a gas-liquid mixture, and the heat released by the refrigerant in the condenser 120 is taken away by a cooling medium (water or air), and in this embodiment, the condenser 120 may be a water-cooled condenser 120 or an air-cooled condenser 120. The evaporator 130 utilizes the liquid low-temperature refrigerant to evaporate at a low pressure, change into vapor and absorb heat of the cooled medium, so as to achieve the purpose of cooling, and in this embodiment, the evaporator 130 can be a cooling liquid refrigerant evaporator 130 or a cooling air evaporator 130. The throttling element is used to throttle the high pressure liquid exiting the condenser 120 down to a reduced pressure, allowing the liquid refrigerant to vaporize and absorb heat at a lower pressure (low temperature). In this embodiment, the throttling device is an automatically adjustable throttling device. Preferably, the throttling means is an electronic expansion valve. The Power Module 161(IPM, Intelligent Power Module) is internally composed of three groups (two in each group) of high-Power switching transistors, and is configured to convert the dc voltage of the input Module into a three-phase ac Power supply for driving the compressor 110 through the switching action of an Insulated Gate Bipolar Transistor (IGBT) therein; the operation frequency of the compressor 110 is completely controlled by the operation voltage outputted by the power module 161, and the higher the voltage outputted by the power module 161 is, the higher the operation frequency and the output power of the compressor 110 are; conversely, the lower the operating frequency and output power of the compressor 110.
The air conditioner obtains the air temperature and air humidity corresponding to the power module 161, and obtains the coil temperature of the heat dissipation coil corresponding to the power module 161. The power module 161 is a part of the electronic control system 160, a temperature sensor and a humidity sensor are installed in the electronic control system 160, and the temperature around an electronic control board in the electronic control system 160 is obtained through the temperature sensor in the electronic control system 160 to obtain the air temperature corresponding to the power module 161; the humidity around the electric control board in the electric control system 160 is obtained through a humidity sensor in the electric control system 160, and the air humidity corresponding to the power module 161 is obtained. It will be appreciated that the electronic control system 160 is used to control the operation of the air conditioner. In this embodiment, in order to dissipate heat of the power module 161 during the operation of the air conditioner, a mechanism for introducing the refrigerant in the air conditioner to the power module 161 is provided. Specifically, a pipeline for flowing the refrigerant may be disposed at a position of the power module 161, and a heat dissipation coil serving as the refrigerant is wound on an outer surface of the power module 161, so that heat of the power module 161 is taken away by the flow of the refrigerant in the heat dissipation coil. Further, a heat dissipation assembly may be disposed on an outer surface of the power module 161, and a heat dissipation coil is disposed in the heat dissipation assembly, and the heat dissipation coil is connected to a refrigerant flowing pipeline, and the refrigerant is introduced into the heat dissipation coil through the refrigerant flowing pipeline to dissipate heat of the power module 161. In this embodiment, as long as it is ensured that the heat dissipation coil and the outer surface of the power module 161 are in a stacked relationship, so that the refrigerant can dissipate heat of the power module 161 through the heat dissipation coil, and the specific connection relationship between the heat dissipation coil and the power module 161 is not specifically limited. In the heat radiation coil, a temperature sensor 1611 is installed, and the coil temperature of the heat radiation coil can be acquired by the temperature sensor 1611, and in this embodiment, the installation position of the temperature sensor 1611 in the heat radiation coil is not limited. The 1611 knowledge in fig. 2 is a schematic diagram of a temperature sensor for detecting the temperature of the heat-dissipating coil, and does not limit the installation location of the temperature sensor for detecting the temperature of the heat-dissipating coil according to the embodiment of the present invention.
And step S20, determining the dew point temperature according to the air temperature and the air humidity.
After the air temperature and the air humidity acquired by the air conditioner, the air conditioner determines the dew point temperature according to the air humidity and the air temperature, wherein the dew point temperature is that when the air temperature is reduced, part of moisture in the air is separated out to form dew or frost, namely under the condition that the content of the water vapor is not changed, the original unsaturated water vapor in the air is changed into saturated vapor due to the reduction of the temperature, and the excessive moisture is separated out to enable the water vapor to reach the temperature when the water vapor is saturated. In the air conditioner, mapping relations between different air temperatures and air humidity and dew point temperatures can be stored in advance, and after the air conditioner obtains the air temperatures and the air humidity, the air conditioner searches the dew point temperatures corresponding to the obtained air temperatures and the obtained air humidity in the mapping relations so as to determine the dew point temperatures. Further, the dew point temperature may also be calculated from the air humidity and the air temperature.
And step S30, if the temperature of the coil pipe is less than the dew point temperature, adjusting the opening of a throttling component in the air conditioner to increase the temperature of the coil pipe and prevent the power module from generating condensation.
When the air conditioner determines the dew point temperature and determines that the acquired coil temperature is less than the dew point temperature, the air conditioner adjusts the opening degree of the throttling component, the coil temperature of the heat dissipation coil is increased by adjusting the opening degree of the throttling component, condensation on the power module 161 is prevented, and normal operation of the power module 161 is guaranteed. It will be appreciated that when the temperature of the coil of the radiator coil decreases, water vapor in the electronic control system 160 will condense due to the temperature decrease, and if the condensation adheres to the power module 161, the power module 161 will not operate normally, and the air conditioner will be in a failure state.
Further, the step S30 includes:
step a, if the temperature of the coil pipe is smaller than the dew point temperature, the opening degree of a first throttling part connected with the condenser is increased so as to increase the temperature of the coil pipe to be larger than or equal to the dew point temperature, and condensation is prevented from being generated on the power module.
Specifically, if the air conditioner determines that the coil temperature is less than the dew point temperature, the air conditioner increases the opening degree of the first throttling part 140 connected to the condenser 120, and increases the coil temperature to be greater than or equal to the dew point temperature by increasing the opening degree of the first throttling part 140, thereby preventing the generation of dew on the power module 161. It should be noted that when the coil temperature is less than the dew point temperature, it indicates that water vapor in the heat dissipation coil will condense, which will adhere to the power module 160. In the present embodiment, the purpose of increasing the opening degree of the first throttling part 140 is to increase the coil temperature of the heat radiating coil, and the magnitude of the increase of the opening degree of the first throttling part 140 is determined by the temperature difference between the coil temperature and the dew point temperature. In the present embodiment, the mapping relationship between the increase amplitude of the opening degree of the throttling part and the temperature difference between the coil temperature and the dew point temperature may be determined in advance through experiments, and stored. When the air conditioner determines that the coil temperature is less than the dew point temperature, the air conditioner calculates a temperature difference between the coil temperature and the dew point temperature, finds an increase amplitude of the opening of the throttling component in the mapping relation according to the temperature difference, and adjusts the opening of the first throttling component 140 according to the increase amplitude. Further, the air conditioner may also directly increase the opening degree of the first throttling component 140, monitor the magnitude relationship between the coil temperature and the dew-point temperature in real time during the process of increasing the opening degree of the first throttling component 140, trigger a stop instruction when the coil temperature is greater than or equal to the dew-point temperature, and stop increasing the increase amplitude of the first throttling component 140 according to the stop instruction.
Further, the control method for preventing condensation of the air conditioner further comprises the following steps:
and b, detecting whether the temperature of the coil is greater than or equal to the dew point temperature.
And c, if the temperature of the coil is detected to be greater than or equal to the dew point temperature, controlling the air conditioner to continue to operate in the current operation state.
Further, after the air conditioner obtains the coil temperature and determines the dew point temperature, the air conditioner detects whether the coil temperature is greater than or equal to the dew point temperature. If the air conditioner detects that the temperature of the coil is greater than or equal to the dew point temperature, the air conditioner continues to operate in the current operation state, namely the opening degree of the throttling component is not adjusted.
The dew point temperature is determined according to the air temperature and the air humidity corresponding to the power module 161 in the air conditioner, when the coil temperature of the heat dissipation coil corresponding to the power module 161 is lower than the dew point temperature, the opening degree of the throttling component in the air conditioner is adjusted, so that the coil temperature of the heat dissipation coil is improved, condensation on the power module 161 is prevented, the opening degree of the throttling component is adjusted, the problem that condensation is generated on the power module 161 in the heat dissipation process of the power module 161 is solved, the normal operation of the power module 161 of the air conditioner is guaranteed, and the normal operation of the air conditioner is guaranteed.
Further, a second embodiment of the control method for preventing condensation of the air conditioner is provided.
The second embodiment of the control method for preventing condensation of an air conditioner is different from the first embodiment of the control method for preventing condensation of an air conditioner in that the control method for preventing condensation of an air conditioner further comprises:
and d, reducing the opening degree of a second throttling part connected with the evaporator to adjust the flow rate of the refrigerant in the air conditioner, so that the flow rate of the refrigerant in the air conditioner is unchanged before and after the opening degree of the throttling part is adjusted.
When the air conditioner is increasing the opening degree of the first throttling part 140, in order to ensure that the output capacity and energy efficiency of the air conditioner are not changed before and after the air conditioner adjusts the opening degree of the throttling part, the air conditioner decreases the opening degree of the second throttling part 150 connected with the evaporator 130 to adjust the flow rate of the refrigerant in the air conditioner, so that the total refrigerant flow rate in the air conditioner is not changed before and after the opening degree of the throttling part is adjusted. When the output capacity of the air conditioner is not changed before and after the opening degree of the throttling part is adjusted, it means that the total refrigerant flow rate in the air conditioner is not changed before and after the opening degree of the throttling part is adjusted. It can be understood that, when the opening degree of the first throttling part 140 is increased, the flow rate of the refrigerant flowing through the first throttling part 140 is increased, and when the opening degree of the second throttling part 150 is decreased, the flow rate of the refrigerant flowing through the second throttling part 150 is decreased.
It should be noted that the air conditioner may decrease the opening degree of the second throttling part 150 while increasing the opening degree of the first throttling part 140; the air conditioner may also decrease the opening degree of the second throttling part 150 after completing the operation of increasing the opening degree of the first throttling part 140.
Further, the control method for preventing condensation of the air conditioner further comprises the following steps:
and e, determining the increasing amplitude of the opening of the first throttling part, and detecting whether the opening and closing steps corresponding to the first throttling part and the second throttling part are the same or not.
If the number of switching steps corresponding to the first throttling component and the second throttling component is the same, the step d comprises the following steps:
and d1, reducing the opening of a second throttling part connected with the evaporator according to the increasing amplitude to adjust the flow rate of the refrigerant in the air conditioner, so that the flow rate of the refrigerant in the air conditioner is unchanged before and after the opening of the throttling part is adjusted, wherein the reducing amplitude of the opening of the second throttling part is equal to the increasing amplitude.
Further, in the process of the air conditioner decreasing the opening degree of the second throttling part 150, the air conditioner determines the increasing magnitude of the opening degree of the first throttling part 140. It is understood that the increase width is a first opening degree, which is an opening degree after the adjustment of the first throttling part 140, to a second opening degree, which is an opening degree before the adjustment of the first throttling part 140. The air conditioner detects whether the number of opening and closing steps of the first throttling part 140 and the number of opening and closing steps of the second throttling part 150 are the same. If the air conditioner detects that the number of opening and closing steps of the first throttling part 140 is the same as the number of opening and closing steps of the second throttling part 150, the air conditioner decreases the opening of the second throttling part 150 connected with the evaporator 130 according to the increase range to adjust the flow rate of the refrigerant in the air conditioner, so that the flow rate of the refrigerant in the air conditioner before the opening of the throttling part is adjusted and the flow rate of the refrigerant in the air conditioner adjusting the opening of the throttling part are not changed, wherein the decrease range of the opening of the second throttling part 150 is equal to the increase range. It is understood that the magnitude of the decrease is a third opening degree, which is an opening degree before the second throttling part 150 is adjusted, to a fourth opening degree, which is an opening degree after the second throttling part 150 is adjusted. When the magnitude of the decrease in the opening degree of the second throttling part 150 is equal to the magnitude of the increase in the opening degree of the first throttling part 140, it indicates that the magnitude of the adjustment in the opening degree of the second throttling part 150 coincides with the magnitude of the adjustment in the opening degree of the first throttling part 140. If the opening degree of the first throttling part 140 is increased by X steps, the opening degree of the second throttling part 150 is decreased by X steps.
Further, in order to improve the accuracy of controlling the refrigerant flow rate in the air conditioner to be constant, when the air conditioner detects that the number of switching steps of the first throttling part 140 is the same as the number of switching steps of the second throttling part 150, it is further detected whether the first caliber corresponding to each switching step of the first throttling part 140 is the same as the second caliber corresponding to each switching step of the second throttling part 150. It can be understood that even if the switching step numbers of the two throttling components are consistent, if the corresponding calibers of the switching step numbers are different, the flow rates of the refrigerant finally flowing through the throttling components are different. In this embodiment, the aperture corresponding to each switching step of the same throttling element is the same.
If it is detected that the first aperture of the first throttling part 140 is the same as the second aperture of the second throttling part 150, the air conditioner decreases the opening degree of the second throttling part 150 connected with the evaporator 130 according to the increase range, so that the decrease range of the opening degree of the second throttling part 150 is equal to the increase range, and the flow rate of the refrigerant in the air conditioner is adjusted; if the first caliber of the first throttling part 140 is different from the second caliber of the second throttling part 150, the air conditioner calculates the caliber ratio between the first caliber and the second caliber, and adjusts the flow rate of the refrigerant in the air conditioner according to the caliber ratio, so that the total refrigerant flow rate in the air conditioner is not changed before and after the opening degree of the throttling part is adjusted.
Further, the control method for preventing condensation of the air conditioner further comprises the following steps:
if the number of switching steps corresponding to the first throttling component and the second throttling component is different, the step d comprises the following steps:
and d2, reducing the opening of a second throttling part connected with the evaporator according to the increasing amplitude to adjust the flow rate of the refrigerant in the air conditioner, so that the flow rate of the refrigerant in the air conditioner is unchanged before and after the opening of the throttling part is adjusted, wherein the ratio of the reducing amplitude and the increasing amplitude of the opening of the second throttling part is equal to a preset ratio.
Further, if the air conditioner detects that the number of opening and closing steps of the first throttling part 140 is different from the number of opening and closing steps of the second throttling part 150, the air conditioner decreases the opening degree of the second throttling part 150 connected with the evaporator 130 according to the increase amplitude to adjust the flow rate of the refrigerant in the air conditioner, so that the total refrigerant flow rate in the air conditioner before and after the opening degree of the throttling part is adjusted is unchanged, wherein the ratio between the decrease amplitude and the increase amplitude of the opening degree of the second throttling part 150 is equal to a preset ratio. It should be noted that what the preset ratio is determined by the number of switching steps of the first throttling part 140 and the number of switching steps of the second throttling part 150.
Further, in order to improve the accuracy of controlling the refrigerant flow in the air conditioner to be constant, when the air conditioner detects that the number of switching steps of the first throttling component 140 is different from the number of switching steps of the second throttling component 150, the air conditioner further detects whether the first caliber of the first throttling component 140 is the same as the second caliber of the second throttling component 150. If the air conditioner detects that the first aperture is equal to the second aperture, the air conditioner reduces the opening of a second throttling component 150 connected with the evaporator 130 according to the increasing amplitude to adjust the flow of the refrigerant in the air conditioner, so that the flow of the refrigerant in the air conditioner is unchanged before the opening of the throttling component is adjusted and after the opening of the throttling component is adjusted, wherein the ratio of the reducing amplitude to the increasing amplitude of the opening of the second throttling component 150 is equal to a preset ratio; if the air conditioner detects that the first caliber is not equal to the second caliber, the air conditioner calculates the caliber ratio between the first caliber and the second caliber, and reduces the opening degree of the second throttling part 150 according to the caliber ratio and the increasing amplitude, so that the refrigerant flow in the air conditioner is unchanged before and after the opening degree of the throttling part is adjusted.
