[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0014] like Figure 1 As shown in the figure, the pipeline system of the environmental simulation test chamber that can adjust the evaporation effect proposed in this utility model embodiment includes a compressor 1, an oil separator 2, a condenser 3, a liquid storage tank 4, a dryer filter 5, a first solenoid valve 6, a thermal bypass valve 7, a second solenoid valve 8, a thermal expansion valve 9, a third solenoid valve 10, a first manual expansion valve 11, a fourth solenoid valve 12, a second manual expansion valve 13, a fifth solenoid valve 14, a third manual expansion valve 15, a main control solenoid valve 16, a first evaporator 17, a second evaporator 18, and a main return gas pipe 19.

[0015] The outlet of compressor 1 is connected to one end of oil separator 2 via a pipeline, and the other end of oil separator 2 is connected to one end of condenser 3 and one end of first solenoid valve 6 via a pipeline; the oil return port of oil separator 2 is connected to compressor 1 via a pipeline; the other end of first solenoid valve 6 is connected to one end of thermal bypass valve 7 via a pipeline, and the other end of thermal bypass valve 7 is connected to main return gas pipe 19 via a pipeline; the other end of condenser 3 is connected to the inlet of liquid storage tank 4 via a pipeline, and the outlet of liquid storage tank 4 is connected to one end of dryer filter 5 via a pipeline; the other end of dryer filter 5 is connected to one end of second solenoid valve 8, one end of third solenoid valve 10, and one end of master control solenoid valve 16 via a pipeline; the other end of second solenoid valve 8 is connected to one end of thermal expansion valve 9 via a pipeline, and the other end of thermal expansion valve 9 is connected to main return gas pipe 19 via a pipeline; the third The other end of solenoid valve 10 is connected to one end of first manual expansion valve 11 via a pipeline, and the other end of first manual expansion valve 11 is connected to the inlet of first evaporator 17 via a pipeline; the other end of master control solenoid valve 16 is connected to one end of fourth solenoid valve 12 and one end of fifth solenoid valve 14 via pipelines; the other end of fourth solenoid valve 12 is connected to one end of second manual expansion valve 13 via a pipeline, and the other end of second manual expansion valve 13 is connected to the inlet of first evaporator 17 via a pipeline; the other end of fifth solenoid valve 14 is connected to one end of third manual expansion valve 15 via a pipeline, and the other end of third manual expansion valve 15 is connected to the inlet of second evaporator 18 via a pipeline; the outlet of first evaporator 17 and outlet of second evaporator 18 are respectively connected to main return gas pipe 19 via pipelines; main return gas pipe 19 is connected to the inlet of compressor 1;

[0016] Compressor 1 pressurizes the refrigerant to form a high-temperature, high-pressure gaseous refrigerant. The lubricating oil is separated by oil separator 2 and returned to the compressor. The high-temperature, high-pressure gaseous refrigerant then enters condenser 3 for condensation, forming a room-temperature, high-pressure liquid refrigerant. When the ambient temperature is high, the refrigerant coming out of condenser 3 will be a gas-liquid mixture. The liquid saturation of the refrigerant can be increased by passing through liquid storage tank 4. The room-temperature, high-pressure liquid refrigerant is dried and impurities are filtered out by dryer filter 5.

[0017] When the ambient temperature is high in summer, the main control solenoid valve 16, the third solenoid valve 10, the fourth solenoid valve 12, and the fifth solenoid valve 14 can be opened; the first manual expansion valve 11, the second manual expansion valve 13, the third manual expansion valve 15, as well as the first evaporator 17 and the second evaporator 18 can all be put into operation, which can enhance the evaporation effect and maximize the cooling effect of the environmental simulation test chamber; each manual expansion valve can reduce the refrigerant pressure and adjust the gas-liquid mixing ratio of the refrigerant entering the evaporator to improve the evaporation efficiency of the refrigerant in the evaporator;

[0018] When the ambient temperature is moderate in spring and autumn, the main control solenoid valve 16, the third solenoid valve 10, and the fourth solenoid valve 12 can be opened, and the fifth solenoid valve 14 can be closed; the first manual expansion valve 11, the second manual expansion valve 13, and the first evaporator 17 can be put into operation, and the evaporation effect of the evaporator is moderate.

[0019] When the ambient temperature is low in winter, the third solenoid valve 10 can be opened and the main control solenoid valve 16 can be closed, so that only the first manual expansion valve 11 and the first evaporator 17 are put into operation, which weakens the evaporation effect of the evaporator and thus reduces the cooling effect of the environmental simulation test chamber.

[0020] The gaseous refrigerant (i.e., return gas) coming out of the evaporator (first evaporator 17 and / or second evaporator 18) returns to the compressor 1 through the main return gas pipe 19 for repressurization. When the return gas temperature is too high, the thermostatic expansion valve 9 increases its opening, allowing some room temperature high-pressure liquid refrigerant to enter the main return gas pipe 19, evaporate and absorb heat, thus lowering the return gas temperature. When the ambient temperature is too low, the first solenoid valve 6 can be opened, allowing a small amount of high temperature high-pressure gaseous refrigerant to enter the main return gas pipe 19 through the thermostatic bypass valve 7, preventing liquid slugging in the compressor 1.

[0021] More preferably, the oil return port of the oil separator 2 is provided with a shock-absorbing ring 20 on the pipeline connecting to the compressor 1; the shock-absorbing ring 20 can reduce the impact of the vibration of the compressor 1 on other components.

[0022] More preferably, a high-pressure gauge 21 and a first pressure relief valve 22 are provided on the outlet pipe of the compressor 1 via a tee; the high-pressure gauge 21 can be used to observe the refrigerant pressure in the outlet pipe of the compressor 1; the first pressure relief valve 22 can prevent the refrigerant pressure in the outlet pipe of the compressor 1 from being too high.

[0023] More preferably, a low-pressure gauge 23 and a second pressure relief valve 24 are provided on the inlet pipe of the compressor 1 via a tee; the low-pressure gauge 23 can be used to observe the refrigerant pressure in the inlet pipe of the compressor 1; the second pressure relief valve 24 can prevent the refrigerant pressure in the inlet pipe of the compressor 1 from being too high.

[0024] More preferably, a sight glass 25 is provided on the pipe at the other end of the dryer filter 5 for observing the liquid saturation of the refrigerant.

[0025] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
