The utility model provides a refrigerating system.
In the embodiment of the present invention, referring to fig. 1, the refrigeration system includes a compressor 10, a cooler 20, a condenser 30 and an evaporator 40, which are connected in sequence, wherein the evaporator 40 is communicated with a gas return pipeline of the compressor 10; the refrigeration system further comprises a heat regulating device 50, wherein an inlet of the heat regulating device 50 is communicated with an outlet of the cooler 20, a cold end 51 of the heat regulating device 50 is communicated with an outlet of the condenser 30, and a hot end 52 of the heat regulating device 50 is communicated with an outlet of the evaporator 40; the heat quantity adjusting device 50 is used to adjust the supercooling degree of the refrigerant flowing through the condenser 30 and the return air temperature of the compressor 10.
Specifically, the compressor 10 is a driven fluid machine that raises low-pressure gas into high-pressure gas, sucks low-temperature and low-pressure refrigerant gas, compresses the refrigerant gas by driving a piston through operation of a motor, and discharges high-temperature and high-pressure refrigerant gas to power a refrigeration cycle. The compressor 10 may be reciprocating, screw, rotary, scroll, and centrifugal, respectively. The low-temperature and low-pressure gaseous refrigerant in the gas return line is compressed by the compressor 10 to form a high-temperature and high-pressure gaseous refrigerant.
Referring to fig. 1, the high temperature, high pressure gaseous refrigerant flows from the compressor 10 into the cooler 20. The cooler 20 is a heat exchange arrangement for cooling a fluid, which may be in a liquid or gaseous state, thereby reducing the temperature of the fluid. The coolant may be used to remove heat from the fluid, and may be water, air or other coolant capable of removing heat. The high-temperature high-pressure gaseous refrigerant is changed into an intermediate-temperature high-pressure gaseous refrigerant by the cooling action of the cooler 20.
Referring to fig. 1, an outlet of the cooler 20 is communicated with an inlet of the condenser 30, and the medium-temperature high-pressure gas refrigerant flows out of the cooler 20 and then enters the condenser 30. The condenser 30 is one of heat exchangers capable of converting a gaseous state into a liquid state. Specifically, gaseous state refrigerant lets in a tubular metal resonator, because the heat conductivility of metal is strong, gaseous state refrigerant gives the tubular metal resonator with heat transfer, and gaseous state refrigerant becomes liquid refrigerant, and the tubular metal resonator gives off the heat to the air again. In order to improve the heat exchange efficiency of the condenser 30, heat dissipation fins with excellent heat conduction performance are often attached to the metal tubes, so that the heat dissipation area is increased to accelerate the heat dissipation, and the air convection is accelerated by the fan to take away the heat. Therefore, the condenser 30 further lowers the temperature of the medium-temperature high-pressure gas refrigerant to liquefy the medium-temperature high-pressure gas refrigerant into a medium-temperature high-pressure liquid refrigerant.
The evaporator 40 is used for converting the liquid refrigerant into the gaseous refrigerant, and the liquid refrigerant passes through the evaporator 40, exchanges heat with the external air, is gasified to absorb heat, and is evaporated into the gaseous refrigerant, so that the external temperature is reduced, and the refrigeration effect is achieved. The evaporator 40 can be classified into a circulation type and a membrane type. The liquid refrigerant is converted to a gaseous refrigerant by evaporation in the evaporator 40 for return to the compressor 10. Thus, the refrigeration cycle of the refrigeration system is compression by the compressor 10, cooling by the cooler 20, condensation by the condenser 30 and evaporation by the evaporator 40, and finally returning to the compressor 10.
Referring to fig. 1, the refrigeration system further includes a heat regulating device 50, an inlet of the heat regulating device 50 is communicated with an outlet of the cooler 20, the cooler 20 converts the high-temperature high-pressure refrigerant into a medium-temperature high-pressure refrigerant, and the heat regulating device 50 performs temperature regulation on the input medium-temperature high-pressure refrigerant to output hot gas (high-temperature gaseous refrigerant) and cold gas (low-temperature gaseous refrigerant) to regulate the temperature of the refrigerant in the refrigeration cycle. That is, the temperature of the refrigerant in the refrigeration cycle is adjusted by using the refrigerant in the refrigeration system, and no additional temperature adjusting liquid is required to be added, so that the compressor 10, the condenser 30 and the evaporator 40 are not damaged, and the cost performance is high.
Referring to fig. 1, the cold end 51 of the heat regulating device 50 is communicated with the outlet of the condenser 30, and the cold air output from the cold end 51 of the heat regulating device 50 is mixed with the medium temperature liquid refrigerant output from the condenser 30 to reduce the temperature of the refrigerant output from the condenser 30, thereby improving the supercooling degree of the refrigerant, facilitating the improvement of the refrigeration efficiency of the refrigeration system, and realizing the refrigeration effect of rapid refrigeration.
Referring to fig. 1, the hot end 52 of the thermal regulator 50 is connected to the outlet of the evaporator 40, and the hot gas output from the hot end 52 of the thermal regulator 50 is mixed with the refrigerant output from the evaporator 40 to increase the temperature of the output refrigerant, so as to further heat the liquid refrigerant that is not evaporated by the evaporator 40 to be completely evaporated, thereby avoiding liquid impact on the compressor 10 and ensuring the reliability of the compressor 10. Thus, the heat regulating device 50 reduces the temperature of the refrigerant flowing out of the condenser 30, and improves the supercooling degree of the refrigerant; at the same time, the refrigerant flowing out of the evaporator 40 is heated, increasing the temperature of the return air of the compressor 10.
The utility model discloses technical scheme passes through heat adjusting device 50's cold junction 51 intercommunication condenser 30's export to cooling down the refrigerant that flows out condenser 30, and then improving the super-cooled rate of the refrigerant of condenser 30 of flowing through, finally improved refrigerating system's refrigeration efficiency. Moreover, the hot end 52 of the heat regulating device 50 is communicated with the outlet of the evaporator 40, and the heat regulating device 50 further heats the refrigerant flowing out of the evaporator 40, so that the refrigerant is completely evaporated into a gaseous state, liquid impact of the compressor 10 is prevented, and the service life of the compressor 10 is prolonged. In addition, the high-temperature and high-pressure gas flowing out of the compressor 10 is the medium-temperature and high-pressure gas after being cooled by the cooler 20, that is, the cooler 20 primarily cools the refrigerant, which is beneficial to further temperature adjustment of the coolant by the heat adjusting device 50.

The vortex tube is an energy separation device which is simple in structure, free of moving parts and easy to control, high-pressure gas can be separated into cold air and hot air flows without consuming extra electric energy or mechanical energy, and the cold and hot separation effect and the air inlet pressure are in a large relation. Generally, the higher the pressure, the better the cold-hot separation effect. Therefore, the vortex tube is adopted to act on the high-pressure refrigerant, and a good cold and hot adjusting effect can be obtained.
Referring to fig. 1, after entering the vortex tube along the tangential direction, the gaseous refrigerant flowing out of the cooler 20 forms a vortex at a high rotation speed, the gaseous refrigerant along the wall of the vortex tube rubs against the wall of the vortex tube to increase the temperature, a part of the gas flow goes out of the hot end 52 of the vortex tube to form a hot gas flow, and the other part of the gas flow returns along the center line to form a backflow, flows in the direction of the gas flow outside the hot end 52 and generates heat exchange, and the temperature is continuously reduced to form a cold gas flow which is discharged from the cold end 51. In this way, by the action of the vortex tube, hot gas is output from the hot end 52 and cooling is output from the cold end 51, thereby adjusting the temperature of the refrigerant in the refrigeration cycle.
