Detailed description of the invention
Fig. 1 is the utility model structure configuration diagram.
In figure, 1. compressors, 2. condensers, 3.1. crosses cold heat exchanger, 3.2. evaporating heat exchanger, 4. expansion valves, 5. evaporations
Device, 6. return-air ducts, 7. oil return interfaces, 8. rich oil refrigerant interfaces, 9. refrigerant oil return pipes.
Specific embodiment
Compressor 1 is connect by pipeline with condenser 2, and condenser is connect further through pipeline with cold heat exchanger 3.1 is crossed, in mistake
The upper end of cold heat exchanger in expansion valve 4 and evaporator 5 by connecting, and portion side is connected with oil return interface 7 and richness under the vaporizers
Oily refrigerant interface 8 is connected to the lower end of evaporating heat exchanger 3.2, the refrigerant oil return in evaporating heat exchanger after the convergence of two interfaces
Pipe 9 and the return-air duct 6 that portion on an evaporator is arranged are linked into the import of compressor together.
Technical principle:
Compressor absorbs the refrigerant in gaseous refrigerant and refrigerant oil return pipe in evaporator, by compressor compresses
Condenser is sent to further through pipeline, and gaseous refrigerant is converted into liquid refrigerant, liquid refrigeration through condenser cooling condensation
Agent passed through cold heat exchanger and continues to cool down, and became gas-liquid mixed refrigerant using expansion valve decompression, output is passed through to evaporator
Evaporator evaporates liquid refrigerant, absorbs heat, and the oil return interface and rich oil that are connected by evaporator middle and lower part freeze
The refrigerant of agent interface further through refrigerant oil return pipe is transported to gaseous refrigerant return-air duct after exchanging heat via evaporating heat exchanger,
Enter compressor by gaseous refrigerant return-air duct, then is recycled by compressor compresses.
In refrigerant circulating process, the effect of condenser is heat dissipation, is applied to and is closed with thermal field, and crosses cold heat exchanger and steam
Sending out heat exchanger is to play the role of recuperation of heat, and the function of evaporator is to evaporate refrigerant, amount of heat is absorbed, for field of freezing
It closes.
It is by evaporating heat exchanger and to cross the heat exchange between cold heat exchanger that this, which expires liquid water cooler, during recycling oil return
Cold consumption in refrigerant, to improve the thermal efficiency of unit.
Condenser is heat-releasing device, and using needs thermal field to close, and evaporator is heat sink, uses refrigeration occasion, and working medium is followed
Ring relies on compressor.
Innovative point is: portion is respectively equipped with oil return interface and rich oil refrigerant interface under the vaporizers, and is provided with supercooling
Heat exchanger and evaporating heat exchanger carry out the cold and hot exchange of cycle fluid by heat exchanger, and by the gaseous refrigerant in evaporator
It is conveyed to compressor together with the refrigerant for being mixed with compressor oil and carries out working medium circulation, exchanged heat using gravity oil return and realize energy conservation.
The course of work:
Refrigeration heat:
High temperature and high pressure gaseous refrigerant is discharged in compressor, enters condenser through pipeline, refrigerant cools down within the condenser to be released
Thermal discharge forms high pressure liquid refrigerant.High pressure liquid refrigerant entered cold heat exchanger through pipeline, and high pressure liquid refrigerant exists
It crosses in cold heat exchanger and is cooled into supercooling high pressure liquid refrigerant.High pressure liquid refrigerant is subcooled and enters expansion valve through pipeline.System
The expanded valve of cryogen depressurizes to form low-temp low-pressure gas liquid mixture.Low-temp low-pressure gas liquid mixture enters evaporator through pipeline.Absolutely
Most of liquid refrigerant absorbs heat in evaporator, forms gaseous refrigerant.Gaseous refrigerant cooled via return air in evaporator
Pipeline enters the air inlet of compressor.High temperature and high pressure gaseous refrigerant is formed through compressor compresses again.
Oil return:
Oil return interface is located at the middle and lower part of evaporator.According to refrigerant property, rich oil refrigerant interface is located at oil-enriched layer.It steams
Part oil-containing liquid refrigerant in device is sent out, evaporation is flowed under the influence of gravity into through oil return interface and rich oil refrigerant interface respectively and changes
Hot device, evaporation generates gaseous refrigerant in evaporating heat exchanger, and contained refrigerator oil passes through refrigerant oil return under air-flow drive
Pipe enters return-air duct.Enter the air inlet of compressor together with the gaseous refrigerant that evaporator generates.
Feature:
Energy loss in refrigeration cycle is avoided using gravity heat exchange oil return.
The two heat exchangers being arranged under the vaporizers are respectively used to generate gaseous refrigerant and high pressure liquid refrigerant are subcooled,
The state conversion for forming refrigerant, is conducive to the interaction of circularly cooling agent, reaches the technical effect of refrigeration recuperation of heat.
