Abstract

The invention discloses a kind of compressed air refrigeration system, be mainly made up of compressor, heat exchanger, decompressor, motor and circuit control system;When Summer Indoor needs refrigeration, indoor heating system is switched to refrigeration module by circuit control system, Indoor Thermal air A passes into after adiabatic compression heats up from compressor and enters heat exchanger a mouth, send from b mouth after heat exchanger heat exchange is lowered the temperature, enter back into decompressor and send cold air B through the backward indoor of adiabatic expansion cooling;When winter, indoor needed to heat, indoor heating system is switched to heating module by circuit control system, and cold air inside C enters heat exchanger c mouth, sends hot-air D to indoor from heat exchanger d mouth after a heat exchange.In this compressed air refrigeration system, the heat exchanging process of heating module is at high temperature carried out, fundamentally avoid frosting problem, not only improved heating effect but also energy efficient, air is also selected to do heat transfer medium, avoid the synthesis cold-producing medium pollution to environment, can be widely applied to warming, cooling in summer system, it is possible to be applied to the refrigeration system such as refrigerator-freezer, refrigerator.

Description

A kind of compressed air refrigeration system
Technical field
The invention belongs to technical field of air conditioner refrigeration, particularly relate to a kind of compressed-air actuated refrigeration system.
Background technology
At present, air-conditioning is when entering winter heating's work, and along with ambient temperature reduces, heating effect is gradually reduced. This is because it is that off-premises station absorbs heat from outside air and passes to indoor by indoor set that winter air-conditioning heats principle, but the winter Season, outside air humidity was generally large, and the steam in air is met condensation on off-premises station and formed frost, reduces heat conductivity, thus Heating effect is made to be deteriorated.
In order to improve the heating effect of winter air-conditioning, off-premises station need to be carried out defrosting process.General use periodically defrosting or Constant temperature defrosting two ways, becomes refrigeration mode by four-way change-over valve switching by heating mode, now heat exchanger of outdoor unit Play condenser effect and release heat, by frost melts.But this Defrost mode not only affects air-conditioning entirety heating effect, also results in Energy waste.
Summary of the invention
The problem that it is an object of the invention to overcome above-mentioned prior art to exist, and a kind of compressed air refrigeration system is provided System, this refrigeration system heat exchanger at high temperature heat exchange, fundamentally avoid frosting problem.
The present invention solves technical problem and adopts the following technical scheme that
A kind of compressed air refrigeration system, including compressor, heat exchanger, decompressor, motor and circuit control system;Described Compressor is connected with heat exchanger a mouth;Described decompressor is connected with heat exchanger b mouth;Described cold air C is from heat exchanger c mouth Enter, after heat exchange, send hot-air D from heat exchanger d mouth;Described hot-air A enters from compressor, heats up through adiabatic compression Rear entrance heat exchanger a mouth, sends from b mouth after heat exchanger heat exchange is lowered the temperature, and enters back into decompressor and lowers the temperature through adiabatic expansion After send cold air B;When winter, indoor needed to heat, indoor heating system is switched to heating module by circuit control system, indoor cold Air C enters heat exchanger c mouth, sends hot-air D to indoor from heat exchanger d mouth after a heat exchange;Summer Indoor When needing refrigeration, indoor heating system is switched to refrigeration module by circuit control system, and Indoor Thermal air A passes into absolutely from compressor Hot compression enters heat exchanger a mouth after heating up, and sends from b mouth after heat exchanger heat exchange is lowered the temperature, and enters back into decompressor through absolutely Cold air B is sent in the backward indoor of thermal expansion cooling.
The above heat transfer medium is air, it is possible to need to become cold-producing medium according to operating mode.
The above heat exchanger is heat-exchangers of the plate type.
The above compressor is centrifugal split-compressor, and described decompressor is centrifugal one-stage expansion machine, compressor With the transmission between decompressor is in same rotating shaft, i.e. in one stage impeller in compressor, sencond stage impeller and decompressor Level impeller is in same rotating shaft, and in compressor, sencond stage impeller is identical with one stage impeller rotating speed in decompressor.
The above motor is connected with compressor, decompressor by rotating shaft, it is possible to by belt pulley, gear and compression Machine, decompressor are connected.
The above heat transfer medium is air, conducts heat for one-level, is not required to pass through change of medium.
The heat exchanging process of the present invention is at high temperature carried out, will not frosting, it is to avoid defrosted during refrigeration below hoarfrost point Journey, had not only improved heating effect but also energy efficient, and used air to do heat transfer medium, it is not necessary to cold-producing medium, it is to avoid synthesis refrigeration The agent pollution to environment.The composite can be widely applied to warming, cooling in summer system, it is possible to be applied to refrigerator-freezer, refrigerator etc. Refrigeration system.
