In this programme, gas-liquid separator 100 is set and is connected between gas returning port 11 and evaporation tube 72, can so avoid
The problem of 10 times liquid of compressor, improves 10 operational reliability of compressor.
Preferably, energy-accumulation material is Polyethylene Glycol phase-change material or is paraffin, expanded graphite phase change composite material.
In sum, the air conditioning system that this utility model is provided, on the basis of traditional air conditioning system increased accumulation of energy and changes
Thermal and the first valve 92, accumulation of energy heat-exchanger rig have two imports, two outlets, are specifically divided into 72 part of evaporation tube and accumulation of heat
73 part of pipe, and inside accumulation of energy heat-exchanger rig, it is filled with heat-storing material, it is considered to heat and defrost time ratio, the heat exchange of evaporation tube 72
The ratio of area and the heat exchange area of heat accumulation pipe 73 is 2-8, in addition, 72 entrance of evaporation tube arranges capillary tube 80, evaporation tube 72 enters
Mouthful with the outlet of evaporation tube 72 by muffler 91 be connected and muffler 91 be provided with described in the first valve 92, the can be controlled
One valve 92 is connected and is disconnected.When air-conditioning is normally heated, the first valve 92 is connection, and coolant is directly by the first valve 92 times
To compressor 10, the aerofluxuss of heating operations through accumulation of energy heat-exchanger rig, as in accumulation of energy heat-exchanger rig, 73 part of heat accumulation pipe is changed
Hot area less, so coolant is trapped during lower minor heat has been put into indoor heat exchanger 40 carries out condensing heating, and stores
Energy heat-exchanger rig stores the heat for obtaining, when, when defrost, throttling arrangement 50 gets to maximum opening, changes from interior
The coolant of hot device 40 is without throttling, or high-temp liquid, so outdoor heat exchanger 60 is entered into after outdoor heat exchanger 60 at which
Row defrosting, now, as the first valve 92 is to close, so coolant can only enter the evaporation tube 72 of accumulation of energy heat-exchanger rig, and
Heat absorption, the evaporation inside accumulation of energy heat-exchanger rig after capillary tube 80 throttles, finally, is compressed beginning into compressor 10 next
Individual circulation, so reach need not shut down commutation also can defrost effect.
