The inlet of the liquid introduction solenoid valve 205 is connected to the pipeline between the outlet of the evaporative cooling module heat exchanger and the liquid circuit solenoid valve 203.

[0046] The compressor 210 may be a step-by-step variable volume ratio compressor or a continuously variable volume ratio compressor.

[0047] The three-way valve 230 and the four-way valve 240 include conventional piston four-way valves and three-way valves or electric three-way valves and four-way valves, but are not limited to ball valve combinations or similar five-way valve designs without the three-way valve 230 and the four-way valve 240 design.

[0048] The copper tube aluminum fin heat exchanger 250 adopts a downstream flow mode under cooling conditions and a countercurrent flow mode under heating conditions; in the downstream flow mode, the air and the refrigerant flow in the same direction, and in the countercurrent flow mode, the air and the refrigerant flow in opposite directions.

[0049] The opening of the ejector 270 can adjust the refrigerant circulation volume of the coil ejection solenoid valve 273 and the EC ejection solenoid valve 271 circuit. The circuit composed of the liquid injection solenoid valve 205 and the one-way valve also plays a role in regulating the refrigerant circulation volume.

[0050] The evaporative cooling module heat exchanger plays a function of storing refrigerant in normal cooling mode or high-efficiency heating mode.

[0051] The boost solenoid valve 201 and the pressure relief solenoid valve 202 can adjust the pressure in the evaporative cooling module heat exchanger when the evaporative cooling module heat exchanger is idle.

[0052] This device is divided into ordinary cooling mode, high-efficiency cooling mode, and high-efficiency heating mode.

[0053] Specifically, such as Figure 3 As shown, when the device operates in the normal refrigeration mode, the compressor 210 discharges the high-temperature and high-pressure refrigerant by doing work, and the discharged high-temperature and high-pressure refrigerant passes through the oil separator 220 to separate the oil in the refrigerant, and is transported to the oil return port of the compressor 210 through the return oil port. The high-temperature and high-pressure refrigerant after the lubricating oil is filtered is transported to the first inlet interface of the four-way valve 240 through the outlet of the three-way valve 230, and the high-temperature and high-pressure refrigerant is transported to the copper tube aluminum fin heat exchanger 250 through the second interface of the four-way valve 240 for heat release and cooling, and is cooled to a medium-temperature and high-pressure liquid refrigerant. The outlet of the copper tube aluminum fin heat exchanger 250 transports the condensed medium-temperature and high-pressure liquid refrigerant through a one-way valve to the electronic expansion valve 204 for pressure reduction and throttling. The low-pressure and low-temperature gas-liquid two-phase refrigerant is transported to the full-liquid heat exchanger 280 through the one-way valve, where it absorbs heat and vaporizes to reduce the temperature of the water in the full-liquid heat exchanger 280. The vaporized low-pressure gaseous refrigerant is transported to the fourth interface of the four-way valve 240 through the outlet of the full-liquid heat exchanger 280 and flows to the intake port of the compressor 210 via the third interface of the four-way valve 240, thereby completing the entire ordinary refrigeration process, wherein the high-pressure and high-temperature gas leaving the outlet of the oil separator 220 passes through the ejector 270 to suck the oil and refrigerant mixture in the oil-rich area outlet of the full-liquid heat exchanger 280 into the ejector 270 interface through the opened cooler ejector solenoid valve 272, and then flows together to the intake port pipeline of the compressor 210. When the refrigerant circulation volume is too large in normal cooling mode, it is discharged to the evaporative cooling module heat exchanger through the liquid circuit solenoid valve 203. When the refrigerant circulation volume is too small, the refrigerant of the evaporative cooling module heat exchanger is transported to the system by opening the EC ejector solenoid valve 271.

[0054] like Figure 2 As shown, when the device operates in the high-efficiency refrigeration mode, the compressor 210 discharges the high-temperature and high-pressure refrigerant by doing work, and the discharged high-temperature and high-pressure refrigerant passes through the oil separator 220 to separate the oil in the refrigerant, and is transported to the oil return port of the compressor 210 through the oil return port. After the lubricating oil is filtered, the high-temperature and high-pressure refrigerant flows through the outlet of the oil separator 220 to the outlet of the three-way valve 230 and flows to the inlet of the precooler 110 in the evaporative cooling module heat exchanger. The high-temperature and high-pressure refrigerant is cooled to a medium-temperature and high-pressure saturated refrigerant through the precooler 110. Then it flows to the copper tube heat exchanger 120 for cooling, wherein the spray water pump 150 in the evaporative cooling module heat exchanger cools the saturated refrigerant in the copper tube heat exchanger 120 by spraying water above the copper tube heat exchanger 120. The spray water after passing through the heat exchange tube copper tube heat exchanger 120 exchanges heat with the air through the filler 160 to reduce its own temperature, and finally falls into the water tank 170 to complete the entire spray water cycle. The air passing through the filler 160 exchanges heat with the water to become humid air, which is heated by the precooler 110 and discharged into the atmosphere by the fan 130. The medium-temperature liquid refrigerant cooled by the copper tube heat exchanger 120 flows to the open liquid circuit solenoid valve 203 through the outlet of the evaporative cooling module heat exchanger, and then undergoes pressure reduction and throttling through the electronic expansion valve 204. The throttled low-pressure and low-temperature gas-liquid two-phase refrigerant is transported to the full-liquid heat exchanger 280 through a one-way valve to absorb heat and vaporize to reduce the temperature of the water in the heat exchanger. The vaporized low-pressure gaseous refrigerant is transported to the fourth interface of the four-way valve 240 through the outlet of the full-liquid heat exchanger 280 and flows to the intake port of the compressor 210 through the third interface of the four-way valve 240, thereby completing the entire high-efficiency refrigeration process. When the refrigerant circulation volume is too large in the high-efficiency refrigeration mode, it is discharged to the copper tube aluminum fin heat exchanger 250 through the liquid inlet solenoid valve 205. When the refrigerant circulation volume is too small, the refrigerant in the copper tube aluminum fin heat exchanger 250 is injected into the pipeline of the suction port of the compressor 210 through the injector 270 by opening the coil injection solenoid valve 273.

[0055] like Figure 4As shown, when the device operates in the high-efficiency heating mode, the compressor 210 discharges the high-temperature and high-pressure refrigerant by doing work, and the discharged high-temperature and high-pressure refrigerant passes through the oil separator 220 to separate the oil in the refrigerant, and is transported to the oil return port of the compressor 210 through the oil return port. After the lubricating oil is filtered, the high-temperature and high-pressure refrigerant flows to the outlet of the three-way valve 230 through the oil separation outlet, and the high-temperature and high-pressure refrigerant then flows from the first interface of the four-way valve 240 to the fourth interface of the four-way valve 240 and is transported to the full-liquid heat exchanger 280 for heat release and cooling, thereby heating the temperature of the water in the full-liquid heat exchanger 280. After cooling is completed, the medium-temperature and high-pressure liquid refrigerant flows to the one-way valve through the refrigerant inlet of the full-liquid heat exchanger 280, and then flows to the electronic expansion valve 2 04 performs pressure reduction and throttling. After completion, the low-temperature, low-pressure gas-liquid mixed refrigerant is transported through the open heating solenoid valve 206 and the one-way valve to the copper tube and aluminum fin heat exchanger 250 for heat absorption and vaporization. After heat exchange, the low-pressure gaseous refrigerant flows through the inlet of the copper tube and aluminum fin heat exchanger 250 to the second port of the four-way valve 240, and then through the third port of the four-way valve 240 to the intake port of the compressor 210, thus completing the high-efficiency heating cycle. When operating in high-efficiency heating mode, if the system refrigerant circulation volume is excessive, it is discharged to the evaporative cooling module heat exchanger through the liquid circuit solenoid valve 203. When the refrigerant circulation volume is insufficient, the refrigerant in the evaporative cooling module heat exchanger is transported back to the system by opening the boost solenoid valve 201 and the liquid introduction solenoid valve 205. When the system needs to defrost in high-efficiency heating mode, the excess refrigerant can be first directed to the evaporative cooling module heat exchanger through the liquid circuit solenoid valve 203 before switching the mode (to normal cooling mode), thereby avoiding the risk of liquid carryover in the compressor 210. When operating in defrost mode, if there is too much refrigerant in the system circulation, the refrigerant circulation amount is controlled by the combination of liquid circuit solenoid valve 203 and pressure relief solenoid valve 202. If the refrigerant circulation amount is too low, the refrigerant in the evaporative cooling module heat exchanger is transported into the system by opening the EC ejector solenoid valve 271.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
