Abstract
The utility model provides a thermal-storage phase-change defrosting device comprising a thermal-storage phase-change device and a defrosting pipeline. The defrosting pipeline is led out from a compressor, passes through an outdoor heat exchanger, converges with a heat supply pipeline sequentially passing through a four-way valve and an indoor heat exchanger, and returns to the compressor after passing through the thermal-storage phase-change device, thus forming circulation. The thermal-storage phase-change device is arranged on a coolant circulation pipeline and is serially connected between the indoor heat exchanger and the outdoor heat exchanger and between the outdoor heat exchanger and the four-way valve and the compressor in an on-off way. The thermal-storage phase-change defrosting device utilizes the heat supply pipeline and the defrosting pipeline which are parallel to each other, and the performance of the original system is not influenced; and with adoption of waste heat of the compressor, the defrosting time is shortened greatly, and heat continues to be supplied to a room.
Description
Technical field
The utility model relates to the defroster field, particularly a kind of accumulation of heat phase transformation defroster.
Background technology
The domestic Defrost mode that heat pump air conditioner and water heater adopted mostly is to utilize the delivery temperature of compressor to carry out the hot gas defrosting at present.Concrete defrost process is: get into defrosting mode-compressor to stop-cross valve switching-over-compressor start-hot gas defrosting-compressor stops-the cross valve switching-over-compressor start-end of spreading unfounded rumours-defrost.
The following weak point that prior art exists:
1, a defrost periods needs start and stop compressor 2 times, and it is high to start energy consumption, and electrical network is had bigger impact, and start and stop frequently reduce the life-span of compressor greatly;
2, a defrost periods cross valve commutates 2 times, and the slide block of inside easy to wear causes cross valve commutation failure rate to raise, the life-span of reduction cross valve;
3, the start and stop of cross valve switching-over and compressor need spend about 4 minutes, and whole defrost process need spend about 12 minutes, need the cost longer time under the adverse circumstances;
4, indoorly during defrost do not heat, also need put a period of time cold wind after defrost finishes could normally heat, and has a strong impact on indoor comfort;
5, defrost only relies on compressor air-discharging to carry out the hot gas defrosting, and energy source is in compressor work, and the highest the highest operate power that can only reach compressor of the energy that is used to defrost causes defrost time length or defrost unclean under the adverse circumstances;
6, wall and external environment are carried out heat exchange during compressor operating, and distribute heat causes delivery temperature to descend to some extent, wastes energy.
External some technology at present adopts the thermal storage defrosting mode.This method is to utilize when normally heating regenerative apparatus to draw and the heat radiation of store compressed machine, derives the heat in the regenerative apparatus during defrosting to be used for defrosting and heat supply again.Cross valve need not commutate during the defrosting of this Defrost mode, compressor do not quit work, and can partly solve the deficiency that above-mentioned domestic prior art exists.
But also there is weak point in this Defrost mode:
Cold-producing medium does not pass through throttling and evaporation when 1, defrosting, and does not have complete kind of refrigeration cycle, can not bring into play the effect that energy is carried in the cold-producing medium phase transformation.
2, cold-producing medium is flowed through becomes supercooled state behind the outdoor heat exchanger, becomes superheated steam behind the regenerative apparatus of flowing through, and it is bigger that both mix the back energy loss.
3, flow through and to be wet-steam phase after the refrigerant mixed of outdoor heat exchanger and storage heater, cause the compressor Wet Compression after getting into compressor, seriously shorten the service life of compressor, also can cause the strong vibrations of outer machine.
4, heat-storing material does not undergo phase transition, and heat storage capacity is relatively poor.Heat-storing material is in a liquid state, and is prone to take place to leak and volatilization.
5, the heat exchanger tube in the storage heater is the snakelike shape of level, is difficult for bending.And its copper pipe is a light pipe, and exchange capability of heat is poor.
6, refrigerant gets into from the condenser bottom during defrost, and by the upwards defrost of condenser bottom, the water that frost is melted into flows down the heat of taking away the bottom from top, be unfavorable for defrost.
