Description
Technical field
This utility model belongs to technical field of air conditioner refrigeration, more particularly, to a kind of refrigeration system of compressed air.
Background technology
At present, air-conditioning, when entering winter heating's work, reduces with ambient temperature, and heating effect is gradually reduced.
This is because it is that off-premises station absorbs heat from outside air and passes to interior by indoor set that winter air-conditioning heats principle, but the winter
Season, outside air humidity was generally large, and the vapor of in the air condenses into frost on off-premises station to the cold, reduces heat conductivity, thus
Heating effect is made to be deteriorated.
In order to improve the heating effect of winter air-conditioning, defrosting process need to be carried out to off-premises station.General using regular defrosting or
Heating mode is changed into refrigeration mode by four-way change-over valve switching, now heat exchanger of outdoor unit by constant temperature defrosting two ways
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.

Adiabatic expansion cooling sends cold air B in interior backward.
The above heat transfer medium is air, needs to be changed into cold-producing medium also dependent on 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
Transmission and decompressor between 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, also can be by belt pulley, gear and compression
Machine, decompressor are connected.
The above heat transfer medium is air, is one-level heat transfer, is not required to by change of medium.
Heat exchanging process of the present utility model is carried out at high temperature, will not frosting, it is to avoid remove when freezing below hoarfrost point
White process, had not only improved heating effect but also energy efficient, and do heat transfer medium using air it is not necessary to cold-producing medium, it is to avoid synthesis
The pollution to environment for the cold-producing medium.This utility model can be widely applied to warming, cooling in summer system, also apply be applicable to ice
