Description

A kind of steam compression type refrigeration circulatory system

Technical field

The utility model relates to be heat-treated and equipment technical field, specially a kind of steam compression type refrigeration circulatory system.

Background technique

Steam compression type refrigeration absorbs the latent heat of vaporization on the basis of this when being built upon liquid vaporization, and its refrigeration energy Power is bigger, therefore steam compression type refrigeration is current using very wide refrigerating method；This refrigerating plant mainly by compressor, Condenser, expansion valve and evaporator composition, firstly, refrigerant vapour is inhaled into compressor, and the insulated overheat that is collapsed into is steamed Vapour；Then the refrigerant vapour under superheat state enters condenser, by constant pressure condensation become refrigerant liquid, refrigerant liquid after And by expansion valve adiabatic throttling, pressure and temperature substantially reduces；Finally, throttling after high humility low-temperature low-pressure refrigerant into Enter evaporator, absorbs heat and evaporate from cold house, to reduce cold house's temperature；And become dry saturated steam after the heat absorption of refrigerant moist steam, Again it is inhaled into compressor again, so constantly recycled；Compressor is refrigeration power-equipment, needs inputing power that can just carry out work Make, but in process of refrigerastion, the power consumption of compressor is bigger, and the height of compressor exhaust temperature will affect energy consumption Size must just reduce compressor exhaust temperature as far as possible then in order to reduce energy consumption, although however at present use various coolings Mode cools down compressor, but is essentially all indirect cooling, and cooling effect is not promoted further, then pressing The delivery temperature of contracting machine is just restricted, and power consumption cannot also further decrease.

Summary of the invention

For in existing steam compression type refrigeration cycle operation, the delivery temperature of compressor is limited, and cooling effect is undesirable, The big problem of power consumption, the utility model provide a kind of steam compression type refrigeration circulatory system, compression can be greatly reduced Machine delivery temperature improves cooling effect, saves power consumption.

Its technical solution is such that a kind of steam compression type refrigeration circulatory system comprising compressor, condenser, steaming Send out device, which is characterized in that it further includes fluid reservoir, atomizer, the compressor, condenser, fluid reservoir, between evaporator successively Closed cycle connection, the atomizer are connected between the fluid reservoir, compressor.

It is further characterized by:

Throttle valve is connected between the fluid reservoir, evaporator.

The beneficial achievement of the utility model is, by being additionally arranged fluid reservoir, atomizer, made of condenser constant pressure condensation Refrigerant liquid is stored in fluid reservoir, is then divided into two-way, is respectively enterd in atomizer and evaporator, then the liquid in atomizer It is mixed into compressor with the refrigerant vapour in compressor, carries out direct-evaporation-type heat exchange, it can be achieved that rapid cooling, cold But effect is relatively good, also significantly reduces the delivery temperature of compressor, is evaporated heat absorption into the liquid in evaporator and forms system Refrigerant vapour is then again sucked into compressor, so constantly recycles and realizes refrigeration, to realize the power consumption of refrigeration Further decrease, solve the problems, such as that existing steam compression type refrigeration energy consumption is excessively high, have preferable use value.

Detailed description of the invention

Fig. 1 is the work structuring flow chart of the utility model.

Specific embodiment

As shown in Figure 1, a kind of steam compression type refrigeration circulatory system of the utility model comprising compressor 1, condenser 2, Evaporator 5, further includes fluid reservoir 3, atomizer 6, compressor 1, condenser 2, fluid reservoir 3, throttle valve 4, between evaporator 5 according to Secondary closed cycle connection, atomizer 6 are connected between fluid reservoir 3, compressor 1.

Compressor 1 is the equipment for improving refrigerant vapor pressure and temperature, provides power for refrigerant circulation.Compressor 1 Refrigerant vapour import is connected by pipeline and the outlet of evaporator 5, and refrigerant vapour outlet is connected by pipeline and 2 import of condenser It connects, the refrigerant atomization liquid-inlet of compressor 1, which is directly exported with atomizer 6, to be connected；

Condenser 2 is refrigerant cooler, and refrigerant heat release under the action of cooling medium is cooling, and condenser 2 exports It is connect by pipeline with the high pressure refrigerant inlet of fluid reservoir 3；

Fluid reservoir 3 is refrigerant storage device, and fluid reservoir 3 sets that there are two high-pressure refrigerants to export, and passes through pipeline difference It is connect with 6 import of atomizer, 4 import of throttle valve；

Evaporator 5 is refrigerant evaporation endothermic device, refrigerant suction coolant media heat of vaporization, and 5 import of evaporator is logical Piping and the outlet of throttle valve 4 connect；

Atomizer 6 is that equipment is steamed in refrigerant liquid atomization, and 6 import of atomizer passes through one of them of pipeline and fluid reservoir 3 High-pressure refrigerant outlet connection, atomizer 6, which exports, directly to be connect with 1 refrigerant of compressor atomization liquid-inlet.

A kind of application method of the steam compression type refrigeration circulatory system comprising following steps:

(1), firstly, the low-temperature low-pressure refrigerant steam in evaporator 5 is inhaled into compressor by refrigerant vapour import 1, the refrigerant liquid that atomizer 6 flows out enters in compressor 1, then compressor 1 is mixed with refrigerant liquid in compression, changed Heat is compacted into superheated steam together, then by 1 refrigerant vapour of compressor outlet discharge, the superheat state after discharge Under the refrigerant vapour of high pressure low temperature enter condenser 2, refrigerant liquid is become by constant pressure condensation；

(2), in the deposit of the refrigerant liquid made of constant pressure condensation fluid reservoir 3, and the refrigerant liquid in fluid reservoir 3 point For two parts outflow, be atomized wherein sub-fraction high pressure refrigerant liquid is only needed to enter in atomizer 6, atomize the liquid into for Fine particle is passed through it in 1 cylinder of compressor, and heat is easy evaporation rapidly, is unlikely to generate liquid hit phenomenon, then can basis The practical pressure and temp situation by compression refrigerant vapour, the liquid after atomization are atomized liquid-inlet by refrigerant and step into In compressor 1, vapour-liquid is carried out with the refrigerant vapour of 1 inner edge of compressor boosting side heating and is mixed, and carries out direct-evaporation-type Heat exchange can inhibit refrigerant vapour and continue to heat up, and become steam after its own heat absorption；And most refrigerant liquid be into Enter to be evaporated heat absorption in evaporator 5 and form refrigerant vapour, i.e., in evaporator 5, low-temperature low-pressure refrigerant absorbs coolant media Heat of vaporization, coolant media are released thermal temperature and are reduced, and realize refrigeration purpose, the low-temperature low-pressure refrigerant steam after evaporation endothermic It is again sucked into compressor 1, refrigerant liquid mixing, the heat exchange that side compression Bian Yucong atomizer 6 comes, then again by pressure Contracting machine 1 exports discharge, so constantly recycles, to can not only realize fast to the refrigerant vapour progress direct-evaporation-type in compression Quickly cooling but, good cooling results, and to steam compression type refrigeration recycle improve refrigerating capacity, reduce electric energy effect consumption it is highly effective so that Steam compression type refrigeration circulation can increase substantially coefficient of refrigerating performance and be possibly realized.
