Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of a module assembly 100 according to an embodiment of the present invention is shown. The module group 100 includes, for example: a wind side heat exchanger 12 and a cooling module. The cooling module is disposed on one side of the wind-side heat exchanger 12, and the cooling module can exchange heat with the wind-side heat exchanger 12. When extreme high-temperature weather occurs, the outdoor environment temperature is extremely high, the temperature difference between the temperature of the wind side heat exchanger 12 and the outdoor environment temperature is small, the heat exchange efficiency is low, the low-temperature cooling module can be controlled to exchange heat with the high-temperature wind side heat exchanger 12 to cool the wind side heat exchanger 12, so that heat accumulated at the wind side heat exchanger 12 is dissipated, the phenomenon that the high-temperature protection or high-pressure protection abnormal shutdown occurs at the module unit 100 due to the overhigh temperature at the wind side heat exchanger 12, the normal refrigeration process is influenced, and the refrigeration effect is reduced; in addition, the operation load of the module unit 100 can be reduced, and the influence of the high-load operation of the module unit 100 on the service life of the module unit can be avoided.

When the cooling module can exchange heat with the wind side heat exchanger 12, low-temperature water at the water side heat exchanger 14 can be directly introduced into the cooling module communicated with the cooling module, and cooling fluid does not need to be additionally arranged for the cooling module, so that the cooling cost is reduced.
Further, the cooling module includes, for example: a cooling element 21, a first cooling line 22 and a second cooling line 23. Wherein the cooling member 21 is disposed at one side of the wind-side heat exchanger 12 and is provided with a first end 211 and a second end 212 opposite to each other; the first cooling pipeline 22 is arranged between the first end 211 and the water side heat exchanger 14, and the cooling piece 21 is communicated with the first end 211 of the water side heat exchanger 14 through the first cooling pipeline 22; the second cooling line 23 is provided between the second end 212 and the water-side heat exchanger 14, and the cooling member 21 communicates with the second end 212 of the water-side heat exchanger 14 through the second cooling line 23.

On one hand, the fan 13 can accelerate the heat exchange speed between the cooling piece 21 and the wind side heat exchanger 12 and improve the heat exchange efficiency between the cooling piece 21 and the wind side heat exchanger 12; on the other hand, the fan 13 itself can also improve the heat exchange efficiency between the outdoor environment and the heat exchanger. Therefore, when extreme high temperature weather is encountered, the wind-side heat exchanger 12 can exchange heat with the outdoor environment and the cooling member 21 quickly, and dissipate heat in time without causing heat accumulation.
In one embodiment, with reference to fig. 2, the cooling element 21 is a wind side cold water side heat exchanger; the air side heat exchanger 12 is an air side refrigerant heat exchanger. The module unit 100 is provided with 3 rows of fin heat exchangers, wherein two rows are air side heat exchangers 12, namely air side refrigerant heat exchangers, and refrigerants circulate in the tubes; the other row is a cooling element 21, namely a wind side cold water side heat exchanger, and cooling water flows in the pipe. Wherein, the air side cold water side heat exchanger is arranged between the fan 13 and the air side refrigerant heat exchanger.

Further, the module assembly 100, for example, further includes: a throttle assembly 15 and a refrigerant compressor 11. The throttling component 15 is arranged in a heat exchange loop of the module unit 100, and the flow of the refrigerant flowing into the wind-side heat exchanger 12 can be controlled by adjusting the opening degree of the throttling component 15. The refrigerant compression device 11 is used to compress a liquid refrigerant into a high-temperature high-pressure gaseous refrigerant. Specifically, when the opening degree of the throttle assembly 15 satisfies the opening degree threshold value and the discharge temperature of the refrigerant compression device satisfies the discharge temperature threshold value, the cooling regulation valve 25 is in the on state.
In one embodiment, the throttling assembly 15 is an electronic expansion valve; the cooling regulating valve 25 is a water path regulating valve; the refrigerant compression device 11 is a compressor. When the opening degree of the electronic expansion valve is opened to the maximum and the exhaust temperature of the compressor is not lower than 95 degrees for 10 seconds, the exhaust temperature of the compressor is too high and exceeds the applicable range of the conventional control and the opening degree of the electronic expansion valve, and if the operation is continued again, the unit is likely to be adversely affected. Therefore, the waterway regulating valve needs to be opened, cooling water in the water side heat exchanger 14 is conducted to the air side cold water side heat exchanger, the temperature of the unit is reduced through a mode that the low temperature air side cold water side heat exchanger exchanges heat with the high temperature air side refrigerant heat exchanger, and normal operation of the unit is guaranteed.
Further, the cooling module, for example, further includes: a discharge air temperature sensor 27 and an outdoor ambient temperature sensor 28. The exhaust temperature sensor 27 is disposed at an exhaust port of the refrigerant compression device 11, and is configured to detect an exhaust temperature of the refrigerant compression device 11; an outdoor ambient temperature sensor 28 is provided on the wind side heat exchanger 12 for outdoor ambient temperature. By arranging the exhaust temperature sensor 27 and the outdoor environment temperature sensor 28, the exhaust temperature and the outdoor environment temperature of the refrigerant compression device 11 can be acquired in real time, a numerical basis is provided for accurate control of the cooling regulating valve 25, and therefore reliability and accuracy of control of the cooling regulating valve 25 are guaranteed.
Further, the cooling module, for example, further includes: a filter device 24. Wherein the filter device 24 is arranged on the first cooling line 22 between the water side heat exchanger 14 and the cooling regulating valve 25. Because be equipped with filter equipment 24 between water side heat exchanger 14 and the cooling governing valve 25, can filter the impurity of water in the water side heat exchanger 14, avoid aquatic impurity to get into cooling governing valve 25 and cause jam and damage, influence the reliability and the accuracy of cooling governing valve 25 control.
Further, the cooling module, for example, further includes: a check valve 26. Wherein the check valve 26 is disposed on the second cooling line 23 such that water in the water-side heat exchanger 14 can only flow into the wind-side heat exchanger 12 through the first cooling line 22 and flow back to the water-side heat exchanger 14 through the second cooling line 23; cannot flow into the wind-side heat exchanger 12 through the second cooling line 23, thereby preventing the water in the cooling module from flowing backward.
The embodiment of the utility model also provides an air conditioner. The air conditioner comprises the module unit. When the air conditioner operates in a cooling mode, the exhaust temperature sensor 27 can detect the exhaust temperature of the refrigerant compression device 11 in real time, and the outdoor environment temperature sensor 28 can detect the outdoor environment temperature in real time; if the outdoor environment temperature is detected to be too high, the condition that the weather is extremely high temperature is indicated. If the opening degree of the electronic expansion valve is opened to the maximum and the exhaust temperature of the compressor is not lower than 95 degrees for 10 seconds, which indicates that the range applicable to the conventional control and the increase of the opening degree of the electronic expansion valve is exceeded, the cooling regulating valve 25 is controlled to be opened, and the temperature of the wind side heat exchanger 12 is rapidly reduced to the normal temperature range by the heat exchange between the cooling piece 21 and the wind side heat exchanger 12, so that the normal operation of the air conditioner is ensured.
Specifically, when the cooling regulating valve 25 is opened, the cooling water in the water-side heat exchanger 14 flows through the filtering device 24, the cooling regulating valve 25, the wind-side heat exchanger 12, the check valve 26 in this order, and finally flows back to the water-side heat exchanger 14.
