Description

Technical Field

[0001] The present invention relates to the field of deicing technology, and in particular to a water tray deicing device, an air cooling unit, a deicing control method, equipment and a medium. Background Art

[0002] The outdoor unit of the air-cooled chiller (hot water unit) uses air to exchange heat with the refrigerant. During winter heating operation, the surface temperature of the outdoor heat exchanger will be lower than the dew point temperature of the outdoor air, causing the moisture in the air to condense into frost on the surface of the outdoor heat exchanger. As the frost layer gradually thickens, it will affect the heat exchange efficiency, so regular defrosting operations are required. During the defrosting process, the heating is stopped and switched to cooling. At this time, the outdoor heat exchanger acts as a condenser, and the surface temperature of the outdoor heat exchanger rises to melt the frost layer. The melted frost water is collected through the defrost water tray and discharged through the drain pipe.

[0003] In some cases, the defrost water tray may freeze, which is usually caused by the ambient temperature being too low. At present, the water tray is mainly defrosted by electric heating, which increases operating energy consumption, has poor ice melting effect, low efficiency, and greatly increases operating costs. The unit can also be set to defrost multiple times for a long time. Multiple defrosting is a periodic operation. Each defrost will clean the system once. The heat during defrosting is transferred to the water tray to help melt the ice in the water tray, which helps to reduce the formation of ice in the water tray and gradually melt it. In the long run, this periodic heat treatment helps prevent the accumulation of ice in the water tray, but this method will shorten the heating time and affect user comfort.

[0067] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0068] Example 1

[0069] This embodiment provides a water tray deicing device, referring to Figures 1 to 3 The water tray deicing device includes: a deicing pipeline 10, a heat storage structure 20, a circulation pump 30 and a heat conduction structure 40.

[0070] The deicing pipe 10 is arranged on the water receiving tray 50. The deicing pipe 10 can be arranged on the upper surface or the lower surface of the water receiving tray 50, as long as the working fluid flowing through the deicing pipe 10 can exchange heat with the water receiving tray 50 to achieve deicing of the water receiving tray 50. Of course, the deicing effect will be better if the deicing pipe 10 is densely and evenly arranged.

[0071] The heat storage structure 20 is connected to the deicing pipeline 10, and the circulation pump 30 is connected to the heat storage structure 20 and the deicing pipeline 10. The circulation pump 30 is used to drive the working medium in the heat storage structure 20 to circulate along the deicing pipeline 10 to connect the water tray 50 for deicing. Driven by the circulation pump 30, the working medium in the heat storage structure 20 can flow into the deicing pipeline 10, flow along the deicing pipeline 10 and return to the heat storage structure 20. The working medium in the heat storage structure 20 can be ethylene glycol, etc. By controlling the working pressure of the circulation pump 30, the flow rate of the working medium in the deicing pipeline 10 can be controlled to meet the deicing requirements.

[0072] The heat-conducting structure 40 contains a working medium, which can undergo phase change and flow in the heat-conducting structure 40. The heat-conducting structure 40 includes an evaporation section 41 and a condensation section 42. The liquid working medium is located in the evaporation section 41. The liquid working medium absorbs heat in the evaporation section 41, undergoes phase change and vaporizes, and becomes a gaseous working medium. The gaseous working medium flows to the condensation section 42. The gaseous working medium releases heat in the condensation section 42, undergoes phase change and liquefies, and becomes a liquid working medium. The liquid working medium returns to the evaporation section 41. In other words, for the heat-conducting structure 40, the part for absorbing heat is called the evaporation section 41, and the part for releasing heat is called the condensation section 42.

[0073] The evaporation section 41 is in contact with the IPM module 60, and the working fluid in the heat-conducting structure 40 absorbs the heat of the IPM module 60 in the evaporation section 41. The condensation section 42 is in contact with the heat storage structure 20, and the working fluid in the heat-conducting structure 40 releases heat to the heat storage structure 20 in the condensation section 42. When the unit is running, the temperature of the IPM module 60 rises, and the working fluid in the heat-conducting structure 40 absorbs the heat of the IPM module 60 in the evaporation section 41, enters the condensation section 42 after vaporization, and the gaseous working fluid releases heat to the heat storage structure 20 in the condensation section 42, completing the transfer of heat from the IPM module 60 to the heat storage structure 20, that is, the evaporation section 41 is used to continuously absorb the heat of the IPM module 60, and the condensation section 42 is used to continuously release heat to the heat storage structure 20, so that the heat of the IPM module 60 can be used to achieve deicing of the water receiving tray. The heat-conducting structure 40 can be a phase change heat-conducting structure such as a heat spreader or a heat pipe, which uses the phase change of liquid-vapor to transfer heat.

[0074] In this embodiment, the heat conducting structure 40 is used to absorb the residual heat of the IPM module 60 and release it to the heat storage structure 20. Under the drive of the circulating pump 30, the hot working medium in the heat storage structure 20 circulates along the deicing pipeline 10 arranged on the water receiving tray 50, and the residual heat of the IPM module 60 is transferred to the water receiving tray 50, so as to realize efficient deicing of the water receiving tray. Compared with the existing electric heating ice melting method or the deicing method of long-term and multiple defrosting, since the evaporation section 41 continuously absorbs heat, the condensation section 42 can continuously release heat for deicing, the electric power loss is small, and a better deicing effect can be achieved, so as to prevent the water receiving tray and even the drain pipe from freezing, ensure the normal operation of the unit, and will not affect the user comfort. The problem of poor deicing effect of the outdoor unit water receiving tray in the prior art is solved, and the heat dissipation of the IPM module can also be realized.

[0075] refer to Figure 3 The circulation pump 30 includes a liquid suction port 31 and a liquid spray port 32. The liquid suction port 31 is connected to the interior of the thermal storage structure 20 through a liquid suction pipeline, and is used to absorb the working medium from the thermal storage structure 20. The liquid spray port 32 is connected to the inlet of the deicing pipeline 10. The thermal storage structure 20 includes a liquid inlet 21, and the liquid inlet 21 is connected to the outlet of the deicing pipeline 10. Thus, a working medium circulation flow path is formed, and the working medium can circulate in the water receiving tray 50 to achieve efficient deicing.

[0076] Based on the principle of phase change heat conduction, the heat conducting structure 40 is a unidirectional heat conductor. During design and installation, the evaporation section 41 is located below the condensation section 42. The liquid working medium in the heat conducting structure 40 is heated and evaporated in the evaporation section 41 and becomes gas. The gas flows upward to the condensation section 42 under the action of pressure difference and releases heat and condenses into liquid in the condensation section 42. Due to the capillary force and gravity of the heat conducting structure 40, the liquid working medium flows back to the evaporation section 41, and the cycle is repeated to achieve efficient heat transfer.

[0077] The heat conducting structure 40 can be a planar structure or a bent structure. Figure 2 The heat conducting structure 40 is a bent structure, the evaporation section 41 is embedded in the IPM module 60, and the condensation section 42 is installed on the upper surface of the water receiving tray 50. Figure 1 and Figure 3 The heat storage structure 20 is also installed on the upper surface of the water receiving tray 50, and the bottom surface 22 of the heat storage structure 20 serves as a heating surface, close to the condensation section 42, that is, the condensation section 42 is located between the bottom surface 22 of the heat storage structure 20 and the upper surface of the water receiving tray 50, so that the bottom surface 22 of the heat storage structure 20 can continuously absorb the heat of the condensation section 42, and through the continuous heat absorption and heat release of the heat conductive structure 40, efficient deicing is achieved.

[0078] like Figure 1 and Figure 2 As shown, the water receiving tray 50 includes at least one drainage hole 51 for drainage.

[0079] Preferably, the water receiving tray 50 is tilted at a preset angle, and the at least one drainage hole 51 is located at the low point of the water receiving tray 50. The preset angle can be set according to actual conditions, for example, the preset angle is set to 3°. In this embodiment, the water receiving tray 50 is tilted at a certain angle and the drainage hole 51 is located at the low point, and the water flows toward the drainage hole 51 under the influence of gravity, ensuring that the water in the water receiving tray after the ice melts can flow smoothly into the drainage hole 51.

[0080] Preferably, reference Figure 1 , the at least one drain hole 51 is arranged on a side close to the condensation section 42. The deicing pipeline 10 can be divided into at least one section of the pipeline, the at least one drain hole 51 corresponds to the at least one section of the pipeline one by one, and any drain hole 51 is located within a preset distance around its corresponding pipeline. The preset distance can be set according to actual conditions, and the value of the preset distance is small to ensure that the drain hole 51 is located near its corresponding pipeline. In this embodiment, a deicing pipeline is arranged around each drain hole, and a drain hole is close to the condensation section 42, which can preferentially prevent the drain hole from freezing, thereby ensuring that the water after the ice in the water receiving tray melts can flow smoothly into the drain hole.

[0081] by Figure 1 For example, a baffle is provided on the side of the water receiving tray 50. When the circulating pump 30 is working, the working fluid in the heat storage structure 20 flows out from the liquid spray port 32, enters the middle deicing pipeline, and is divided into two paths when it flows to the first water receiving tray baffle. The two paths flow along the second water receiving tray baffle (left side) and the third water receiving tray baffle (right side) respectively, and then flow to the side of the fourth water receiving tray baffle. After merging, they return to the heat storage structure 20 through the liquid inlet 21 of the heat storage structure 20 to continue to absorb the heat of the condensation section 42.

[0082] The de-icing pipeline can use a bellows. The wave height and wave period of the bellows will affect the turbulent state of the fluid and the longer the flow path, the more conducive to heat exchange. The bellows are easy to form turbulence, thereby enhancing the heat exchange effect and accelerating ice melting. In addition, the contact area of ​​the bellows placed on the water tray is larger than that of ordinary pipes, and the de-icing effect is better.

[0083] During cooling operation, the temperature of the IPM module 60 increases. In the prior art, the refrigerant before throttling is usually used to continuously cool the IPM module 60, but this increases the enthalpy value, loses the supercooling degree, reduces the cooling capacity, and leads to reduced energy efficiency.

[0084] refer to Figure 4The air-cooling unit includes: a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, a heating electronic expansion valve 4, an IPM module 60, a cooling electronic expansion valve 5, an indoor heat exchanger 6, and a gas-liquid separator 7. A temperature sensing package is provided at the IPM module 60 for detecting the temperature of the IPM module 60, and the temperature sensing package can be controlled by a timing program. In this embodiment, a cooling electronic expansion valve 5, a valve 8, an IPM module 60, and a heating electronic expansion valve 4 are sequentially connected in series between the indoor heat exchanger 6 and the outdoor heat exchanger 3. The cooling electronic expansion valve 5, the valve 8, and the IPM module 60 are connected in parallel with a first one-way valve 91, and the conduction direction of the first one-way valve 91 is from the indoor heat exchanger 6 to the outdoor heat exchanger 3. The heating electronic expansion valve 4 is connected in parallel with a second one-way valve 92, and the conduction direction of the second one-way valve 92 is from the outdoor heat exchanger 3 to the indoor heat exchanger 6. A first pipeline 93 is connected in series between the outlet of the first one-way valve 91 and the inlet of the cooling electronic expansion valve 5. The valve 8 may be a valve element with an on-off control function.

[0085] In this embodiment, a valve 8 is set between the IPM module 60 and the refrigeration electronic expansion valve 5, and a first pipeline 93 is set. During refrigeration operation, the heat of the IPM module 60 can be absorbed by the heat-conducting structure 40 to cool the IPM module 60. The refrigerant flowing out through the second one-way valve 92 can enter the refrigeration electronic expansion valve 5 through the first pipeline 93. At this time, the refrigerant does not flow through the IPM module 60 to avoid loss of cold. When the temperature of the IPM module 60 is too high and the heat-conducting structure 40 is insufficient to cool the IPM module 60, the valve 8 is opened to lead a refrigerant to the IPM module 60 for cooling, thereby reducing the impact on the heat exchange of the unit. At the same time, the problem of de-icing the water tray and the problem of loss of cold caused by continuous use of refrigerant to cool the IPM module 60 during refrigeration of the unit are solved.

[0086] In this embodiment, when the unit is running, the heat of the IPM module 60 can be transferred to the water receiving pan 50, and the water receiving pan 50 can be efficiently melted with good ice melting effect during heating operation. During cooling operation, the heat conducting structure 40 can help dissipate the heat of the IPM module 60 to reduce the cooling loss caused by continuous use of refrigerant to dissipate heat from the IPM module 60.

[0087] Example 2

[0088] This embodiment provides an air-cooled unit, including: the water tray deicing device described in the above embodiment.

[0089] In this embodiment, the heat conducting structure 40 is used to absorb the residual heat of the IPM module 60 and release it to the heat storage structure 20. Under the drive of the circulating pump 30, the hot working medium in the heat storage structure 20 circulates along the deicing pipeline 10 arranged on the water receiving tray 50, and the residual heat of the IPM module 60 is transferred to the water receiving tray 50, so as to realize efficient deicing of the water receiving tray. Compared with the existing electric heating ice melting method or the deicing method of long-term and multiple defrosting, since the evaporation section 41 continuously absorbs heat, the condensation section 42 can continuously release heat for deicing, the electric power loss is small, and a better deicing effect can be achieved, so as to prevent the water receiving tray and even the drain pipe from freezing, ensure the normal operation of the unit, and will not affect the user comfort. The problem of poor deicing effect of the outdoor unit water receiving tray in the prior art is solved, and the heat dissipation of the IPM module can also be realized.

[0090] Example 3

[0091] This embodiment provides a deicing control method, which is applied to the water tray deicing device described in the above embodiment. Figure 5 is a flow chart of a deicing control method provided by an embodiment of the present invention, such as Figure 5 As shown, the method comprises the following steps:

[0092] S501, when the air-cooled unit is in heating operation, the outdoor ambient temperature is detected.

[0093] S502 , controlling the circulation pump 30 according to the outdoor ambient temperature, so as to utilize the heat of the IPM module 60 to de-ice the docking water tray 50 .

[0094] In this embodiment, the waste heat of the IPM module 60 is transferred to the water receiving pan 50, so as to realize efficient de-icing of the water receiving pan. Compared with the existing electric heating ice melting method or the de-icing method of long-term multiple defrosting, since the evaporation section 41 continuously absorbs heat, the condensation section 42 can continuously release heat for de-icing, the electric power loss is small, and a better de-icing effect can be achieved, thereby preventing the water receiving pan and even the drain pipe from freezing, ensuring the normal operation of the unit, and not affecting the user comfort. The problem of poor de-icing effect of the outdoor unit water receiving pan in the prior art is solved, and the heat dissipation of the IPM module 60 can also be realized.

[0095] In one embodiment, the circulation pump 30 is controlled according to the outdoor ambient temperature to utilize the heat of the IPM module 60 to connect the water tray 50 for de-icing, including: determining whether the outdoor ambient temperature is less than a first preset temperature; if the outdoor ambient temperature is less than the first preset temperature, turning on the circulation pump 30 (the circulation pump 30 runs at the minimum pressure by default when it is just turned on), and adjusting the working pressure of the circulation pump 30 according to the liquid spray port temperature of the circulation pump 30 and the liquid inlet temperature of the heat storage structure 20; if the outdoor ambient temperature is greater than or equal to the first preset temperature, turning off the circulation pump 30.

[0096] The first preset temperature is used to measure the outdoor ambient temperature to determine whether the water receiving pan 50 is prone to freezing. If the outdoor ambient temperature is lower than the first preset temperature, it means that the water in the water receiving pan 50 has a tendency to freeze, and the circulation pump 30 needs to be turned on. The first preset temperature can be set according to actual conditions, for example, the first preset temperature is set to 0°C.

[0097] This embodiment can control the circulation pump 30 according to actual conditions, thereby meeting the deicing requirements of the water receiving tray.

[0098] Furthermore, the working pressure of the circulation pump 30 is adjusted according to the temperature of the liquid spray port of the circulation pump 30 and the temperature of the liquid inlet of the heat storage structure 20, including: detecting the temperature of the liquid spray port of the circulation pump 30, and detecting the temperature of the liquid inlet of the heat storage structure 20 after a first preset time; calculating the absolute value of the difference between the liquid inlet temperature and the liquid spray port temperature to obtain the current actual temperature difference; determining the working pressure corresponding to the current actual temperature difference as the target pressure of the circulation pump 30 according to the corresponding relationship between the preset temperature difference and the working pressure of the circulation pump; and controlling the circulation pump 30 to operate according to the target pressure.

[0099] Among them, the first preset time can be set according to actual conditions, for example, the first preset time is set to 1 minute. The absolute value of the difference between the liquid inlet temperature and the liquid spray outlet temperature can reflect the deicing demand of the water tray 50. If the absolute value of the difference is large, it means that the heat exchange between the deicing pipeline 10 and the water tray 50 is large. At this time, there is an ice layer on the water tray 50. The larger the absolute value of the difference, the more ice needs to be melted. The working pressure of the circulation pump 30 should be increased to speed up the flow rate of the working fluid, and the bellows is easy to form turbulence to enhance the heat exchange effect and accelerate ice melting; if the absolute value of the difference is small, it means that the deicing demand is not large, and the working pressure of the circulation pump 30 can be reduced to slow down the flow rate of the working fluid.

[0100] The corresponding relationship between the temperature difference and the working pressure of the circulating pump can be established in advance through experiments. For example, the working pressure P of the circulating pump and the temperature difference △T are linearly related, and the specific values ​​are obtained through theoretical calculation and experimental verification, P=k×△T+b, k and b are constants, and different working pressures of the circulating pump are set at multiple different temperature differences to observe the ice melting effects respectively. The value is taken when the ice melting effect is the best, and two sets of data are taken for each temperature difference of 5°C. For example, two sets of data (△T1, P1) and (△T2, P2) are taken between the temperature difference of 0°C and 5°C, and the corresponding coefficients k and b values ​​are calculated based on the two sets of data, thereby obtaining the relationship corresponding to the temperature difference interval of [0°C, 5°C]. Similarly, two sets of data are taken between the temperature difference of 5°C and 10°C to obtain the relationship corresponding to the temperature difference interval of [5°C, 10°C]. Therefore, in actual control, after obtaining the actual temperature difference, the working pressure of the circulation pump corresponding to the actual temperature difference can be calculated as the required target pressure by using the relationship corresponding to the temperature difference interval in which the actual temperature difference is located.

[0101] This embodiment controls the working pressure of the circulation pump 30 based on the actual temperature difference between the liquid inlet temperature and the liquid injection port temperature, which can meet the deicing requirements.

[0102] When the air-cooled unit is in heating operation, it also includes: closing the valve 8, wherein the valve 8 is located between the refrigeration electronic expansion valve 5 and the IPM module 60. At this time, the refrigerant flowing out of the first one-way valve 91 directly enters the heating electronic expansion valve 4, and the refrigerant does not flow through the IPM module 60. The IPM module 60 is cooled by continuously absorbing heat from the evaporation section 41, and the condensation section 42 continuously releases heat to the heat storage structure 20, thereby achieving de-icing of the water tray and cooling of the IPM module.

[0103] When the air-cooled unit is in cooling operation, the temperature of the IPM module 60 rises. In the prior art, the refrigerant before throttling is usually used to continuously cool the IPM module 60, but this increases the enthalpy value, loses the supercooling degree, reduces the cooling capacity, and leads to reduced energy efficiency.

[0104] In order to solve this problem, the above method may also include: when the air-cooled unit is in refrigeration operation, turning on the circulation pump 30 and controlling the circulation pump 30 to operate at a preset pressure; detecting the temperature of the IPM module 60; and controlling the valve 8 and the circulation pump 30 according to the temperature of the IPM module 60, wherein the valve 8 is located between the refrigeration electronic expansion valve 5 and the IPM module 60.

[0105] Among them, the preset pressure is the circulating pump working pressure corresponding to the best heat exchange effect between the de-icing pipeline 10 and the water receiving tray 50. For example, the preset pressure can be determined by the cooling speed. When the temperature of the IPM module 60 is 70°C, the circulating pump 30 is turned on to different working pressures. When the temperature of the IPM module 60 drops to 60°C, the time required for the temperature to drop by 10°C at different working pressures is calculated, and the working pressure corresponding to the shortest time is used as the circulating pump working pressure with the best heat exchange effect.

[0106] In the present embodiment, during refrigeration operation, the circulation pump 30 is turned on, and the heat-conducting structure 40 and the heat storage structure 20 are preferentially used to dissipate heat and cool the IPM module 60, thereby avoiding the problem of cooling loss caused by continuous use of refrigerant to cool the IPM module 60.

[0107] Further, the valve 8 and the circulation pump 30 are controlled according to the temperature of the IPM module 60, including:

[0108] Step 1, determining whether the temperature of the IPM module 60 is less than a second preset temperature;

[0109] Step 2: If the temperature of the IPM module 60 is lower than the second preset temperature, the valve 8 is closed. At this time, the refrigerant flows into the refrigeration electronic expansion valve 5 through the first pipeline 93, and the refrigerant does not flow through the IPM module 60, thereby avoiding the situation where the refrigerant is absorbed by the high temperature of the IPM module 60, resulting in loss of cooling capacity and reduction of the unit capacity.

[0110] Step 3: If the temperature of the IPM module 60 is greater than or equal to the second preset temperature, control the valve 8 and the circulation pump 30 according to the temperature change of the IPM module 60 .

[0111] The second preset temperature is used to measure the temperature of the IPM module 60 . The second preset temperature can be set according to actual conditions. For example, the second preset temperature is set to 70° C.

[0112] This embodiment controls the valve 8 and the circulation pump 30 according to the temperature of the IPM module 60, and can take appropriate cooling measures to dissipate the heat of the IPM module 60, thereby achieving effective heat dissipation and avoiding cold loss.

[0113] Further, the valve 8 and the circulation pump 30 are controlled according to the temperature change of the IPM module 60, including:

[0114] Step 31, detecting the temperature of the IPM module 60 once every second preset time, and determining the temperature change of the IPM module 60, wherein the second preset time can be set according to actual conditions, for example, the second preset time is set to 1 minute;

[0115] Step 32, if the temperature of the IPM module 60 increases or remains unchanged, it means that the heat dissipation efficiency of the circulation pump 30 is not high at this time, and the heat-conducting structure 40 is insufficient to dissipate the heat of the IPM module 60. At this time, the valve 8 is opened and the circulation pump 30 is closed, and a pre-throttling refrigerant is introduced to effectively cool the IPM module 60. Closing the circulation pump 30 can reduce the power of the unit;

[0116] Step 33, if the temperature of the IPM module 60 decreases, it means that the heat absorbed by the evaporation section 41 of the heat-conducting structure is higher than the heat generated by the IPM module. The IPM module 60 tends to cool down, and there is no need to introduce refrigerant to cool down the IPM module 60. At this time, the valve 8 is closed and the circulation pump 30 is controlled to maintain the preset pressure.

[0117] In this embodiment, when the temperature of the IPM module 60 is greater than or equal to the second preset temperature, the valve 8 and the circulation pump 30 are controlled according to the temperature change of the IPM module, and appropriate cooling measures can be taken to dissipate the heat of the IPM module 60, which can both effectively reduce the temperature in time and avoid cooling loss.

[0118] While closing the valve 8 and controlling the circulation pump 30 to maintain the preset pressure, it also includes: if the number of consecutive executions of the step of determining the temperature change of the IPM module 60 is greater than the preset number, it means that the IPM module 60 dissipates heat too slowly, and at this time, the valve 8 is opened and the circulation pump 30 is closed, and the IPM module 60 is quickly and effectively dissipated by the refrigerant before throttling; if the number of consecutive executions of the step of determining the temperature change of the IPM module 60 is less than or equal to the preset number, return to the step of determining whether the temperature of the IPM module 60 is less than the second preset temperature. The preset number can be set according to actual conditions, for example, the preset number is set to 5 times.

[0119] In this embodiment, when the IPM module 60 dissipates heat too slowly, the refrigerant before throttling is used to quickly and effectively dissipate heat for the IPM module 60, and the circulating pump 30 is turned off to reduce the power of the unit and improve energy efficiency. It should be noted that in this case, the effect of the circulating pump 30 and the refrigerant dissipating heat for the IPM module 60 is certainly better, but when the two act at the same time, the effect of the refrigerant dissipating heat is much greater than that of the circulating pump 30. At this time, the temperature of the IPM module drops quickly, and the heat acting on the heat-conducting structure 40 is not much. If the circulating pump 30 is turned on at this time, the disadvantages outweigh the advantages, and the power increases but the heat dissipation effect is not greatly improved.

[0120] In one embodiment, after the valve 8 is opened and the circulation pump 30 is closed, the process further includes: when the temperature of the IPM module 60 drops to a third preset temperature, the valve 8 is closed, the circulation pump 30 is opened, and the circulation pump 30 is controlled to operate at the preset pressure, wherein the third preset temperature is lower than the second preset temperature. The third preset temperature can be set according to actual conditions, for example, the third preset temperature is set to 60°C.

[0121] In this embodiment, when the temperature of the IPM module drops to the third preset temperature, the valve 8 is closed and the circulation pump 30 is turned on to run at a preset pressure to continue to dissipate heat from the IPM module 60, delaying the temperature of the IPM module from rising to the second preset temperature without causing cooling loss.

[0122] The above deicing control method is described below in conjunction with a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustrating the present application and does not constitute an improper limitation on the present application. The explanation of terms that are the same or corresponding to the above embodiment will not be repeated in this embodiment.

[0123] like Figure 6 As shown, de-icing control includes the following steps:

[0124] S601, unit operation.

[0125] S602: When the unit is in heating operation, close valve 8 and detect the outdoor ambient temperature T1. Figure 4 During heating operation, the D end and the E end of the four-way valve 2 are connected, and the C end and the S end are connected, and the refrigerant flow direction is: 1→D→E→6→91→4→3→C→S→7→1.

[0126] S603, determine whether T1<T2 is satisfied, if yes, proceed to S605, if no, proceed to S604. T2 represents the first preset temperature, which can be 0°C.

[0127] S604, the circulation pump 30 is turned off.

[0128] S605, the circulation pump 30 is turned on and operates at the minimum pressure by default when it is just turned on.

[0129] S606, detecting the temperature T3 of the liquid spraying port of the circulation pump 30, and detecting the temperature T4 of the liquid inlet of the heat storage structure 20 after 1 minute.

[0130] S607, calculate the temperature difference △T=|T4-T3|.

[0131] S608, adjusting the working pressure of the circulation pump according to ΔT.

[0132] S609, when the unit is in refrigeration operation, the circulation pump 30 is turned on and operates at a preset pressure, and the temperature T5 of the IPM module 60 is detected.

[0133] S610, determine whether T5<T6 is satisfied, if so, proceed to S611, if not, proceed to S612. T6 represents the second preset temperature, which can be 70°C.

[0134] S611, close valve 8.

[0135] S612, recording the temperature of the IPM module 60 every 1 minute.

[0136] S613, determine whether the temperature of the IPM module 60 is reduced. If so, proceed to S614, if not, proceed to S616.

[0137] S614, the valve 8 is closed and the circulation pump 30 operates at a preset pressure.

[0138] S615, determine whether the number of consecutive executions of the temperature change determination step (ie, S613) is greater than 5. If so, it means that the time exceeds 5 minutes and the IPM module 60 dissipates heat too slowly, and enter S616. If not, return to S610.

[0139] S616, open valve 8 and close circulation pump 30.

[0140] S617, when the temperature of the IPM module drops to T7, the valve 8 is closed and the circulation pump 30 is turned on to operate at a preset pressure. T7 represents the third preset temperature, which can be 60°C.

[0141] refer to Figure 4 During refrigeration operation, the D end and the C end of the four-way valve 2 are connected, and the E end and the S end are connected. If the valve 8 is closed, the refrigerant flows as follows: 1→D→C→3→92→93→5→6→E→S→7→1. If the valve 8 is opened, the refrigerant flowing out of the second one-way valve 92 is divided into two paths, one path enters the refrigeration electronic expansion valve 5 through the first pipeline 93, and the other path enters the refrigeration electronic expansion valve 5 through the IPM module 60 and the valve 8.

[0142] In this embodiment, the waste heat of the IPM module 60 is transferred to the water tray 50 for de-icing through the heat-conducting structure 40, thereby realizing efficient de-icing of the water tray with good de-icing effect, ensuring the normal operation of the unit, greatly reducing power consumption, saving energy consumption, and not affecting user comfort. In addition, the waste heat of the IPM module 60 is fully utilized to realize effective heat dissipation of the IPM module 60. During cooling operation, the heat of the IPM module 60 is helped to be dissipated, reducing the loss of cooling capacity, and solving the problems of poor de-icing effect of the water tray of the outdoor unit during heating and the loss of cooling capacity caused by continuous heat dissipation of the IPM module by the refrigerant during cooling.
