Abstract
The utility model discloses an air source heat pump water heater set with an adjustable evaporation area. A fin evaporator and an expansion valve are arranged in a heat pump system, wherein liquid separators are arranged between the fin evaporator and the expansion valve. The two liquid separators are connected in parallel, and one liquid separator is connected with a control valve. Each liquid separator is connected with a plurality of thin pipes which are connected with the fin evaporator. The utility model with reasonable structure reduces the evaporating pressure and the evaporating temperature during the heat production under high temperature in summer by adjusting the evaporation area so as to prolong the service life of the set.
Description
Technical field:
The utility model relates to a kind of heat pump.
Background technology:
Existing heat-pump hot-water unit is when heat summer, because environment temperature height, humidity reach, the load of evaporimeter increases a lot, and directly consequence is exactly that evaporating temperature, suction superheat are too high, so evaporating pressure, suction temperature height.Evaporating pressure is too high, and pressure ratio is crossed the low compressor electric motor overload that makes easily, causes the generator protection shutdown, heats and can not normally move.Regular protection simultaneously also can be shortened compressor service life.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can improve the unit adjustable air-source heat pump hot water group of disengagement area in service life by regulating disengagement area, reduce summer high temperature evaporating pressure and evaporating temperature when heating.
Technical solution of the present utility model is:
The air-source heat pump hot water group that a kind of disengagement area is adjustable, evaporator fin, expansion valve are arranged in the heat pump, between evaporator fin and expansion valve, knockout is set, it is characterized in that: knockout is the knockout of two parallel connections, one of them knockout is connected with control valve, each knockout coupling part tubule, tubule is connected with evaporator fin.
The utility model is rational in infrastructure, has used two knockouts in the system, and evaporating pressure is in normal range of operation the time, cold-producing medium is walked two knockouts, when evaporating pressure is higher than normal value, passes through adjusting control valve, only allow single knockout work, thereby realize the reasonable adjusting of disengagement area.Evaporating pressure and evaporating temperature when heating by regulating disengagement area, reducing summer high temperature make system's operation reach the Performance Match of more optimizing, and the raising unit is the service life of compressor particularly.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
The air-source heat pump hot water group that a kind of disengagement area is adjustable, evaporator fin 1, expansion valve 2 are arranged in the heat pump, between evaporimeter 1 and expansion valve 2, knockout is set, knockout is the knockout 3,4 of two parallel connections, one of them knockout 3 is connected with magnetic valve 5, each knockout coupling part tubule 6, tubule 6 is connected with evaporator fin 1.
Present embodiment heat the water circulation process: compressor 7-cross valve 8-water-cooled condenser 9-reservoir 10-device for drying and filtering 11-expansion valve 2-evaporator fin 1-cross valve 8-gas-liquid separator 12-compressor 7 (magnetic valve controls according to low pressure and cuts out and open);
The defrost cycle flow process is:
Compressor 7-cross valve 8-evaporator fin 1-expansion valve 2-device for drying and filtering 11-reservoir 10-water-cooled condenser 9-cross valve 8-gas-liquid separator 12-compressor 7.
