Background technology
The structure of heat pump type air conditioner is substantially identical with single cold type air-conditioner, and when autumn and winter, it utilizes air-conditioning in the principle of cooling in summer, but adopts with contrary refrigerant flow direction in summer, reaches the object of indoor heating.As can be seen here, under indoor heating and indoor refrigeration both of these case, the heat exchanger of indoor set and the heat exchanger exchange function of off-premises station, namely when indoor refrigeration, refrigerant completes condensation change in the heat exchanger of off-premises station, completes evaporation change in the heat exchanger of indoor set, and when indoor heating, refrigerant completes condensation change in the heat exchanger of indoor set, completes evaporation change in the heat exchanger of off-premises station.For convenience, no matter heat pump type air conditioner is in indoor heating or indoor refrigeration, and this description all claims the heat exchanger of off-premises station to be condenser, and claims the heat exchanger of indoor set to be evaporimeter (being consistent with single cold type air-conditioner).
Work as autumn and winter, when heat pump type air conditioner is in indoor heating, because outdoor temperature is lower, and complete in condenser be refrigerant evaporation change, so in the easy frosting of condenser surface, thick frost layer can cause air constricted flow, affect the heating capacity of air-conditioning.In order to defrost, current heat pump type air conditioner usually adopts refrigeration, heats the mode of switching, but adopt in this way, in defrost process, indoor can not continue to heat, cause indoor temperature to fluctuate up and down comparatively large, have a strong impact on indoor comfortableness, therefore, how better defrost, avoiding affecting indoor comfortableness becomes those skilled in the art's technical problem urgently to be resolved hurrily.
Summary of the invention
In view of this, the invention provides a kind of off-premises station for heat pump type air conditioner, heat pump type air conditioner, described heat pump type air conditioner comprises described off-premises station, and described off-premises station can avoid the stability affecting indoor temperature when defrost, is conducive to maintaining indoor comfortableness.
In order to achieve the above object, the invention provides following technical scheme:
A kind of off-premises station for heat pump type air conditioner, the capillary comprising condenser coil and be connected with described condenser coil, described capillary is in order to be communicated with the evaporimeter of indoor set, described condenser coil and described intercapillary pipeline are provided with Electrothermal ring, the gauge tap of described Electrothermal ring detects that the temperature of described condenser coil is opened lower than making described Electrothermal ring be energized during the first preset temperature, the gauge tap of described Electrothermal ring detects that the temperature of described condenser coil is closed higher than making described Electrothermal ring power-off during the second preset temperature, described first preset temperature is less than described second preset temperature.
Preferably, in above-mentioned off-premises station, described Electrothermal ring wraps up along a complete cycle of pipeline outer wall.
Preferably, in above-mentioned off-premises station, the scope of described first preset temperature T1 is :-40 DEG C≤T1≤30 DEG C; The scope of described second preset temperature T2 is :-40 DEG C≤T2≤30 DEG C.
Preferably, in above-mentioned off-premises station, the material of described Electrothermal ring is copper, aluminium or iron.
A kind of heat pump type air conditioner, comprises indoor set and above-mentioned off-premises station.
According to technique scheme, when heat pump type air conditioner is in indoor heating, run a period of time, condenser coil temperature is reduced to below the first preset temperature, Electrothermal ring energising is opened, and condenser coil and intercapillary pipeline are heated, heat is directly passed to pipeline after producing heat by Electrothermal ring, pipeline transfers heat to the cold coal inside pipeline again after absorbing heat, improve the temperature entering refrigerant before condenser, off-premises station is made to reach the effect of defrosting, when defrost, heat pump type air conditioner processes without the need to carrying out shutdown like this, ensure that defrost has lasting hot blast to blow out in indoor simultaneously, make indoor temperature field evenly, avoid the stability affecting indoor temperature, be conducive to maintaining indoor comfortableness.
