Abstract
The utility model relates to an air source heat pump water heating machine provided with a defrosting device, belonging to the heat pump water heating machine technical field and aiming at providing the air source heat pump water heating machine which can quickly and thoroughly remove a frost layer generated on the surface of an evaporator of the heat pump water heating machine. The utility model is provide with the main technical points that on the basis of the existing air source heat pump water heating machine, a water draining pipe (5) in a heat pump hot water loop formed by a water feeding pipe, a water draining pipe, a refrigerant heat transmission tube of a bushing condenser, a water heat exchanger and a water tank is connected with a spraying device (12) arranged on the upper part of an evaporator (9) by a bypass through a hot water tube (7). As the spraying device arranged on the upper part of the evaporator (9) is connected with the water draining pipe in the heat pump hot water loop by the bypass, the utility model can make use of parts of the heated hot water in the heat pump hot water loop to spray the evaporator and then to carry out a reverse defrosting matching with a four-way reversing valve, thus realizing the aim of safe, quick and thorough defrosting and further enhancing heat exchanging efficiency of the air source heat pump water heating machine.
Description
Technical field:
The utility model relates to a kind of air-source heat pump hot water, particularly a kind of air-source heat pump hot water that is provided with defroster.
Background technology:
Heat pump water-heating machine is emerging in recent years a kind of health hot water generator, wherein is most widely used with air heat source.But when the air-source heat pump hot water environment that temperature is lower in the winter time moved down, evaporator surface generated one deck frost layer easily, causes heat exchange efficiency to reduce, so air-source heat pump hot water need possess the defrosting measure.The reverse defrost of four-way change-over valve is mainly adopted in the defrosting of air source hot pump water heater at present, hot-gas bypass defrosting, electrical heating defrosting mode.The unclean defective of its preceding two kinds of Defrost modes existence defrosting, and last a kind of electrical heating defrosting mode, the then potential safety hazard that power consumption is big and existence is leaked electricity.
Summary of the invention:
The purpose of this utility model provides a kind of air-source heat pump hot water that is provided with defroster, and it can carry out rapidly, defrost up hill and dale the frost layer of evaporator surface generation, with the heat exchange efficiency of raising evaporimeter, and need not consume a large amount of electric energy.
Its technical scheme is: a kind of air-source heat pump hot water that is provided with defroster, comprise blower fan, by compressor, four-way change-over valve, double-pipe condenser-cold-producing medium heat pipe and water heat exchanger, two-way heating power expansion valve, the refrigerant circulation loop that evaporimeter and pipeline constitute, by advancing, outlet pipe, the heat-pump hot-water loop that double-pipe condenser-cold-producing medium heat pipe and water heat exchanger and water tank constitute, and automaton, it is characterized in that: on the outlet pipe in the described heat-pump hot-water loop, connect the spray equipment that is arranged on evaporimeter top by the hot-water line bypass.
Be connected with magnetic valve between hot-water line that described bypass connects and the spray equipment by automaton control.
Described spray equipment is that shower is provided with a plurality of apopores.
Its technique effect is: owing to bypass connection one on the outlet pipe in the heat-pump hot-water loop is arranged on the spray equipment on evaporimeter top, utilize the part hot water after being heated in the heat-pump hot-water loop to go evaporimeter is sprayed, cooperate the reverse defrost of four-way change-over valve again, can remove the frost layer of evaporator surface effectively, both can overcome and only depend on reverse defrost of four-way change-over valve or the hot-gas bypass unclean defective of existing defrosting that defrosts, it is big and have a deficiency of the potential safety hazard of electric leakage to have solved electrical heating defrosting power consumption again, thereby can realize safety, fast, thoroughly defrost, further improve the purpose of air-source heat pump hot water heat exchange efficiency; And it is simple in structure, and defrosting is reliable.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
As shown in Figure 1, a kind of air-source heat pump hot water that is provided with defroster, comprise blower fan 11, by the refrigerant circulation loop of compressor 1, four-way change-over valve 2, double-pipe condenser-cold-producing medium heat pipe and water heat exchanger 3, two-way heating power expansion valve 8, evaporimeter 9 and pipeline 13 formations and the heat-pump hot-water loop that constitutes by inlet tube and outlet tube 4,5, double-pipe condenser-cold-producing medium heat pipe and water heat exchanger and water tank 6.On the outlet pipe 5 in the heat-pump hot-water loop, connect the spray equipment 12 that is arranged on evaporimeter top by hot-water line 7 bypass.
Be connected with magnetic valve 10 between hot-water line 7 that described bypass connects and the spray equipment 12 by automaton control.
Described spray equipment 12 is provided with a plurality of apopores for shower.
Its course of work that defrosts: in running order down when air-source heat pump hot water, when reaching the defrosting condition of setting, automaton cuts off the power supply of blower fan 11 automatically, makes blower fan out of service.Meanwhile, 2 commutations of automaton control four-way change-over valve, working medium is discharged from compressor 1, flows through four-way change-over valve 2, evaporimeter 9, two-way heating power expansion valve 8 successively to double-pipe condenser-cold-producing medium heat pipe and water heat exchanger 3, gets back to compressor 1 after heat exchange.In this process, the working medium of evaporimeter of flowing through defrosts to it by heat release, simultaneously, automaton is connected the power supply of magnetic valve 10 automatically, this magnetic valve must be conducted, will be through the hot water that produces after double-pipe condenser-cold-producing medium heat pipe and water heat exchanger 3 heat exchange, by hot-water line 7 through magnetic valve 10 to spray equipment 12, the apopore on the spray equipment carries out defrosting with hot water spray to evaporimeter 9.
