[0051] The operation of the control valve electronic expansion valve II 304 in the two branches where the control valve XV 303 and the control valve XVI 305 are located.

[0052] The heat exchange tube performance test section 300 is used to study the heat exchange characteristics of the refrigerant and the heat exchange tube test section 301. When conducting the test, only one of the branches where the control valve fifteen 303 and the control valve sixteen 305 are located is opened. The high-temperature and high-pressure refrigerant gas flows out from the exhaust port of the linear compressor 10, and on the pipeline, it is first cooled to a low-temperature and high-pressure subcooled refrigerant liquid by the refrigeration unit cooling section 100 through the control valve one 12, and then flows through the dryer filter 13, lens one 14, control valve five 15, Coriolis mass flowmeter 17, control valve seven 18, and preheater 302. The preheater 302 is used to adjust the subcooling degree of the refrigerant.

After the pressure-reduced refrigerant liquid passes through the heat exchange tube test section 301, control valve seventeen 306, lens two 20, and solenoid valve 204, then the control valve ten 207 is opened and the control valve nine 205 and the electronic expansion valve one 206 are closed. After the high-temperature and low-pressure refrigerant liquid enters and exits the calorimeter 201, it flows through the control valve twelve 22 and the control valve thirteen 11 and is connected to the suction port of the linear compressor 10; if the refrigerant does not need to be throttled before entering the heat exchange tube test section 301, the control valve sixteen 305 on one of the branches of the circuit is opened, and the control valve fifteen 303 and the electronic expansion valve two 304 on the other branch are closed. After the refrigerant flows through the control valve sixteen 305, it passes through the heat exchange tube test section 301, control valve seventeen 306, lens two 20, and solenoid valve 204. At this time, the control valve nine 205, the electronic expansion valve one 206 are opened and the control valve ten 207 is closed. After the pressure-reduced low-temperature refrigerant liquid enters and exits the calorimeter 201 and becomes a high-temperature and low-pressure refrigerant gas, it flows through the control valve twelve 22 and the control valve thirteen 11 and is connected to the suction port of the linear compressor 10. When the heat exchange tube performance test section is operating, the control valves on other performance test sections are all in the closed state.

[0053] When the heat exchange tube performance test section conducts the test, only one of the two branches where the control valve fifteen 303 and the control valve sixteen 305 are located is opened.

[0054] When the refrigerant is throttled before entering the heat exchange tube test section 301, the branch where the electronic expansion valve two 304 is located is opened, and the branch where the electronic expansion valve one 206 in the linear compressor performance test section 200 is located is closed; when the refrigerant is throttled after entering the heat exchange tube test section 301, the branch where the electronic expansion valve two 304 is located is closed, and the branch where the electronic expansion valve one 206 in the linear compressor performance test section 200 is located is opened.

[0059] The two branches where the control valve XVIII 402 and the control valve XIX 404 are located control the operation of the electronic expansion valve III 403.

[0060] The ice storage cooling performance test section 400 is used to study the performance of the refrigerant cooling the secondary refrigerant of the linear compressor 10 and provide effective data support for the design of the miniaturized compressor device. During the test, only one of the branches where the control valve XVIII 402 and the control valve XIX 404 are located is opened. The high-temperature and high-pressure refrigerant gas discharged from the exhaust port of the linear compressor 10 is cooled into a low-temperature and high-pressure subcooled refrigerant liquid by the refrigeration unit cooling section 100 through the pipeline in sequence via the control valve I 12, passes through the dryer filter 13, the lens I 14, the control valve V 15, the Coriolis mass flowmeter 17, and the control valve VII 18. If throttling is required before the refrigerant enters the ice storage cooling cylinder 401, the control valve XVIII 402 and the electronic expansion valve III 403 on the loop are opened to control the flow of the branch where they are located, the branch where the control valve XIX 404 is located is closed, the refrigerant passes through the control valve XVIII 402 and the electronic expansion valve III 403 and then enters and exits the ice storage cooling cylinder 301, and then passes through the control valve XX 405, the lens II 20, and the solenoid valve 204. At this time, after opening the control valve X 207 and closing the control valve IX 205 and the electronic expansion valve I 206, the low-pressure and low-temperature refrigerant liquid enters and exits the calorimeter 201 and becomes a high-temperature and low-pressure refrigerant gas, flows through the control valve XII 22 and the control valve XIII 11, and is connected to the suction port of the linear compressor 10; if throttling is not required before the refrigerant enters the ice storage cooling cylinder 401, the control valve XIX 404 on the loop is opened to control the flow of the branch where it is located, the branches where the control valve XVIII 402 and the electronic expansion valve III 403 are located are closed, the refrigerant enters and exits the ice storage cooling cylinder 401 through the control valve XX 405, the lens II 20, and the solenoid valve 204. At this time, the control valve IX 205, the electronic expansion valve I 206 are opened and the control valve X 207 is closed, the low-pressure refrigerant liquid with reduced pressure enters and exits the calorimeter 201 and becomes a high-temperature and low-pressure refrigerant gas, and passes through the control valve XII 22 and the control valve XIII 11 and is connected to the suction port of the linear compressor 10. When the ice storage cooling performance test loop is running, the control valves on other performance test sections are all in the closed state.

[0061] When the ice thermal storage performance test unit 400 conducts tests, only one of the two branches where the control valve XVIII 402 and the control valve XIX 404 are located is opened.

[0062] In the ice thermal storage performance test unit 400, when the refrigerant is throttled before entering the ice thermal storage cylinder 401, the branch where the electronic expansion valve III 403 is located is opened, and the branch where the electronic expansion valve I 206 in the linear compressor performance test unit 200 is located is closed; when the refrigerant is throttled after entering the ice thermal storage cylinder 401, the branch where the electronic expansion valve III 403 is located is closed, and the branch where the electronic expansion valve I 206 in the linear compressor performance test unit 200 is located is opened.

[0063] If it is observed from the lens II 20 that the refrigerant gas is liquid-free in the heat exchange tube performance test unit 300 and the ice thermal storage performance test unit 400, the solenoid valve 204 and the control valve XII 22 are closed, and the control valve XIV 23 is opened. Instead of passing through the calorimeter 201, the test circuit passes through the control valve XIV 23 and the control valve XIII 11 and is connected to the suction port of the linear compressor 10, which can reduce the fluid resistance loss and heat exchange loss in the circuit.
