[0020] When the adaptive material distribution needs to be temperature adjusted, the device can be used. In the heating mode, the refrigerant leaves the compressor 1 in a high-pressure high-temperature steam state and flows into the discharge pipeline 2 and is transferred to the reversing valve. The reversing valve is in the heating mode. The operation of the reversing valve makes the refrigerant in the discharge pipeline 2 flow into the first return pipeline 3, flows into the left ordinary heat exchanger 6 from the branch pipe 5, and the branch pipe 5 is L-shaped, facilitating the flow of refrigerant. At the same time, the refrigerant flows into the right ordinary heat exchanger 6 from the first return pipeline 3, and then is switched by the operation of the second reversing valve 13. The water pump 12 is started again, so that the liquid in the corresponding layer flows through the second reversing valve 13 and flows into the refrigerant inlet 7 and enters the ordinary heat exchanger 6 to adjust the temperature of the refrigerant to a suitable temperature, so that the adjusted refrigerant flows from the refrigerant outlet 8 into the indoor heat exchanger 9, blows cold air through the indoor unit, detects the temperature through the temperature sensor 10, so that the cold air blows through the indoor heat exchanger 9 to remove heat energy, and provides warm air for the room. When the heat is removed, the adjusted refrigerant condenses into liquid and flows into the second return pipeline 11 and flows back to the liquid storage tank 14. The liquid storage tank 14 is divided into upper, middle and lower storage spaces. The heat conductivity of the refrigerant stored in each space is different. Then the water pump 12 is closed. The original refrigerant leaves the ordinary heat exchanger 6 in a high-temperature slightly cold liquid state, flows back to the third return pipeline 16, so that the refrigerant flows to the positions of the expansion valve 17 and the stop valve 18. The flow direction of the refrigerant is observed through the sight glass 20. At this time, the right stop valve 18 is in the open state, and the left stop valve 18 is in the closed state, so that the refrigerant flows through the bidirectional dry filter 19 to filter impurities from the right stop valve 18, and then flows into the left expansion valve 17. The refrigerant expands and changes back to a mixture of part liquid and part steam, so that the temperature and pressure are reduced. Then the refrigerant flows into the outdoor heat exchanger 15, so that the external environment air exchanges heat with the refrigerant to heat the refrigerant. The refrigerant boils at low temperature to absorb heat and leaves the outdoor heat exchanger 15 in the form of low-temperature low-pressure slightly overheated steam. Then the refrigerant flows into the discharge pipeline 2, flows back to the first reversing valve 4, and is reversed by the first reversing valve 4, so that the refrigerant flows back to the compressor 1 to repeat the cycle, thereby realizing heating for the room. When in cooling mode, the high-temperature high-pressure steam refrigerant flows into the discharge pipeline 2, and then flows into the outdoor heat exchanger 15. The outdoor unit blows the ambient air through the outdoor heat exchanger 15. Because the temperature is lower, it can drive the heat energy in the refrigerant. The refrigerant condenses when it loses heat energy. The refrigerant leaves the outdoor heat exchanger 15 in a high-pressure slightly cold liquid state, flows into the third return pipeline 16, and flows to the positions of the expansion valve 17 and the stop valve 18.The third reflux pipe 16 is E-shaped, facilitating the reflux of refrigerant, and the flow direction of refrigerant is observed through the sight glass 20. At this time, the left stop valve 18 is in an open state, and the right stop valve 18 is in a closed state, so that the refrigerant flows from the left stop valve 18, passes through the bidirectional dry filter 19 to filter impurities, and then flows into the expansion valve 17 of the right part to flow out, so that the refrigerant becomes a mixture of part liquid and part vapor, the temperature and pressure decrease, the refrigerant flows into the common heat exchanger 6, and then is switched by the operation of the second reversing valve 13. The water pump 12 is started again, so that the liquid in the corresponding layer flows through the second reversing valve 13 and flows into the refrigerant inlet 7 and enters the common heat exchanger 6 to adjust the temperature of the refrigerant to a suitable temperature. The adjusted refrigerant flows from the refrigerant outlet 8 into the indoor heat exchanger 9, blows warm air through the indoor unit, and the temperature is detected by the temperature sensor 10, so that the heat is transferred into the refrigerant, the refrigerant boils to take away heat, and the room is cooled. The refrigerant leaves the indoor heat exchanger 9 in a low-temperature, low-pressure and slightly superheated state, flows out from the second reflux pipe 11, and flows back to the liquid storage tank 14. Then the water pump 12 is turned off, the first reflux pipe 3, the second reflux pipe 11 and the third reflux pipe 16 are all made of copper material, which has good heat conductivity, mechanical strength and corrosion resistance. The original refrigerant in the left common heat exchanger 6 flows back to the first reflux pipe 3 from the branch pipe 5, and the original refrigerant in the right common heat exchanger 6 flows back to the first reflux pipe 3. The refrigerant enters the discharge pipe 2 through the operation of the first reversing valve 4, and then flows back to the compressor 1 to repeat the cycle, thereby realizing cooling for the room, and realizing self-adaptive material temperature adjustment. Thus, the refrigerant temperature can be adjusted according to the storage temperature of the material to supply heat to the room, realize self-adaptive temperature adjustment for material storage, reduce energy consumption, save cost, prolong the shelf life of the material, and after use, the compressor 1, the common heat exchanger 6, the indoor heat exchanger 9, the water pump 12, the outdoor heat exchanger 15, the expansion valve 17, the stop valve 18 and the bidirectional dry filter 19 can be turned off.
