Abstract
The utility model discloses a thermal-electric coupling defrosting air-energy heat-pump water heater which comprises a heat pump assembly that is provided with an evaporator, a condenser, a compressor and an expansion valve, wherein a gas-liquid separator in which an electric heater is installed is arranged between the evaporator and a suction inlet of the compressor in the heat pump assembly. The utility model has the advantages of reasonable structure, good defrosting effect and long service life of the pump assembly.
Description
Technical field:
The utility model relates to a kind of Teat pump boiler, is a kind of air energy heat pump water heater.
Background technology:
Existing air energy heat pump water heater, its defrost mode comprises cross valve defrost, bypass defrosting etc., and unit carries out cold and hot switching when adopting the cross valve defrost, and making to heat needs the side forced refrigeration, has a strong impact on the use that heats side; The refrigerant gas heating frosting fin that the hot-gas bypass defrost is discharged by compressor, after the cold-producing medium heat release condensation, do not evaporate endothermic process, do not have heat to suck owing to have only heat to emit on the one hand, the unit operating mode is very unstable, and the defrost effect is relatively poor, liquid refrigerant is assembled in a large number in suction side on the other hand, probably can cause liquid refrigerant directly to enter compressor, cause compressor liquid hammer and lubricating oil dilution, reduce unit durability greatly; Evaporator fin electrification frost is that the electric heater coil pipe is placed on the evaporator fin, because the relative electric heater area of evaporator fin is very big, frostization on the whole evaporimeter is intact, need the long period, in addition in this longer defrost time, electric heater not only conducts heat to evaporimeter, and also low temperature environment heat radiation towards periphery in a large number causes very power consumption of defrost.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and defrost is effective, the thermocouple combination frost air energy heat pump water heater of unit long service life.
Technical solution of the present utility model is:
A kind of thermocouple combination frost air energy heat pump water heater, comprise source pump, source pump has evaporimeter, condenser, compressor, expansion valve, is provided with gas-liquid separator in the source pump between evaporimeter and compressor suction inlet, it is characterized in that: electric heater is housed in gas-liquid separator.
In source pump, be provided with the bypass defrosting device.Condenser adopts the inboard shell and tube condenser of leaking water, sidle fluorine outward.
The utility model is rational in infrastructure, service life is normal, specific volume is little mutually with the white heater of general evaporation device fin electrification to be placed on the interior electric heater of gas-liquid separator, easy for installation, and the heat that electric heater provides can be to all being used to the low temperature environment heat radiation, finally all be used for defrost, so the heat that electrical heating provides has also been accelerated the speed of defrost.When adopting bypass defrosting to combine, can effectively overcome the defective of simple bypass defrosting with the auxiliary heating of electricity defrost.Defectives such as overcome that unit that conventional air energy heat pump water heater exists air-breathingly forces down, the unit operating mode is very unstable, defrost weak effect, liquid refrigerant assemble, cause liquid refrigerant directly to enter compressor in a large number in suction side, cause compressor liquid hammer and lubricating oil dilution, unit service life is short.
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:
A kind of thermocouple combination frost air energy heat pump water heater, comprise source pump, source pump has evaporimeter 1, condenser 2, compressor 3, expansion valve 4, magnetic valve 5, filter 6, stop valve 7, reservoir 8 etc., between evaporimeter 1 and compressor 3 suction inlets, be provided with gas-liquid separator 9 in the source pump, electric heater 10 is housed in gas-liquid separator 9.In source pump, being provided with the bypass defrosting device--defrosting magnetic valve 11, one of defrosting magnetic valve 11 terminates between expansion valve and the evaporimeter.Condenser 2 adopts the inboard shell and tube condenser of leaking water, sidle fluorine outward, and fouling is few, easy cleaning.
