[0040] The refrigerant input assembly 21, the refrigerant output assembly 22 and the temperature sensor are all in communication connection with the controller.

[0041] like Figure 3 and Figure 4 As shown, the refrigerant input assembly 21 includes a refrigerant input tank 23, a pump body 1 and an input pipe 25, and the refrigerant output assembly 22 includes a refrigerant output tank 24, a pump body 2 and an output pipe 26. The refrigerant input tank 23 is connected to the first liquid storage tank 31 through the input pipe 25, and the refrigerant output tank 24 is connected to the second liquid storage tank 32 through the output pipe 26. The pump body 1 is installed on the input pipe 25, and the pump body 2 is installed on the output pipe 26. Both the pump body 1 and the pump body 2 are communicatively connected to the controller.

[0042] like Figure 2 and Figure 3 As shown, the refrigerant input assembly 21 further includes a one-way valve 27 , and the refrigerant output assembly 22 further includes a one-way valve 28 . The one-way valve 27 is installed on the input pipe 25 , and the one-way valve 28 is installed on the output pipe 26 .

[0043] like Figure 2 and Figure 3 As shown, the refrigerant quantitative control mechanism 2 further includes a refrigerant connecting pipe 29, and both ends of the refrigerant connecting pipe 29 are respectively connected to the refrigerant input tank 23 and the refrigerant output tank 24.

[0044] The detection mechanism also includes a pressure gauge, which is installed on the compressor 1 and is communicatively connected with the controller.

[0045] It also includes an alarm component and a timer. The alarm component is installed on the first liquid storage tank 31, and the timer is installed on the first liquid storage tank 31. Both the alarm component and the timer are connected to the controller for communication.

[0047] like Figure 1 As shown, a drying filter 9 is also included, and the drying filter 9 is located between the expansion valve 8 and the liquid storage tank mechanism 3.

[0048] Air-cooled modular unit refrigeration working principle:

[0049] During refrigeration, the compressor 1 sucks in the low-pressure and low-temperature gas refrigerant in the gas-liquid separator 6. The gas refrigerant works through the compressor 1 and becomes a gas refrigerant with higher pressure and temperature. It enters the air heat exchanger 4 through the four-way reversing valve 5. The air circulates in the air heat exchanger 4 to take away the heat. At this time, the gas refrigerant with higher pressure and temperature releases heat and becomes a liquid refrigerant with lower temperature. Then, it flows through the first liquid storage tank 31, the second liquid storage tank 32, the drying filter 9 and the expansion valve 8 in sequence. It is decompressed and expanded by the expansion valve 8 to become a low-pressure liquid refrigerant. Then, the liquid refrigerant flows into the water heat exchanger 7. Then, the liquid refrigerant absorbs heat and vaporizes. The water outside the water heat exchanger 7 is cooled to meet the use requirements. Then, the refrigerant flows into the gas-liquid separator 6 through the four-way reversing valve 5 to complete a refrigeration cycle.

[0050] In multiple refrigeration cycles, if the pressure gauge detects that the corresponding condensing pressure is too low, or the temperature sensor detects that the corresponding evaporation temperature is too low, the pressure gauge or the temperature sensor sends a signal to the controller, and the controller sends a signal to the refrigerant input component 21, and the refrigerant input component 21 re-inputs liquid refrigerant into the first liquid storage tank 31 to prevent the actual working refrigerant from being too little;

[0051] In multiple refrigeration cycles, if the pressure gauge detects that the corresponding condensing pressure is too high or the temperature sensor detects that the corresponding evaporating temperature is too high, the pressure gauge or the temperature sensor sends a signal to the controller, and the controller sends a signal to the refrigerant output component 22. The refrigerant output component 22 re-sucks out part of the liquid condensing agent from the first liquid storage tank 31 to prevent excessive condensing agent in actual work.
