Abstract
The utility model relates to an air source heat pump water heater with a hot water spraying defrosting device. A hot water circulating pipeline is provided with an electromagnetic valve and a hot water spraying pipe, fully combining the structural characteristics of the air source heat pump water heater. The water heater utilizes the existing hot water circulation to defrost directly with a circulating pipeline which is simple and reliable, fast to defrost and high in thermal efficiency.
Description
Technical field
The utility model relates to a kind of air source hot pump water heater, particularly with the air source hot pump water heater of heat water-spraying's defroster.
Background technology
At present, air source hot pump water heater generally defrosts by modes such as commutation of electric heating, cross valve or hot-gas bypass, the simple in structure but operating cost height of electric defrosting; Fast but the refrigerating circulation complexity of cross valve reverse cycle defrost speed, internal leakage influences the efficient of heat pump cycle and is difficult to guarantee reliable commutation.
Summary of the invention
The utility model is the air source hot pump water heater that proposes novel band heat water-spraying defroster in order to overcome problems such as having air source hot pump water heater defrosting structure complexity, poor reliability now, abundant design feature in conjunction with air source hot pump water heater, utilize the direct defrost of existing hot water circuit, circulation line is simple and reliable reliable, and defrosting speed is fast, thermal efficiency height.
The technical solution of the utility model is a kind of air source hot pump water heater with heat water-spraying's defroster, comprise Teat pump boiler, arrange heat water-spraying's pipe near the cold wind evaporimeter of described Teat pump boiler, be used for defrosting to evaporating heat exchanger, the recirculated water delivery side of pump connects a recirculated water bypass and enters described heat water-spraying's pipe, has magnetic valve to be used to control the bypass break-make in the recirculated water bypass.
The beneficial effects of the utility model are: fully in conjunction with the design feature of air source hot pump water heater, utilize the direct defrost of existing hot water circuit, circulation line is simple and reliable, and defrosting speed is fast, thermal efficiency height.
Description of drawings
Fig. 1 is the air source hot pump water heater structured flowchart of the utility model band heat water-spraying defroster.
The specific embodiment
As shown in Figure 1, divide working medium circulation and two circulations of water circulation in the heat pump, working medium cycles through compressor 1, make working medium (as R22) shuttling movement that the physical phase transition process take place repeatedly, vaporization heat absorption, the heat release of in water-cooled condenser 2, liquefying in cold wind evaporimeter 4 respectively, make heat constantly obtain exchange and transmit, water cycles through cyclic water tank 6, water circulating pump 5, water-cooled condenser 2 and takes the heat in the water-cooled condenser 2 out of cyclic water tank.
The utility model has increased a magnetic valve 7 and shower 8 at hot water circulating pipeline, arrange that near cold wind evaporimeter 4 heat water-spraying manages 8, outlet at water circulating pump 5 connects a recirculated water bypass, control its break-makes with magnetic valve 7 in the recirculated water bypass, when satisfied " defrosting enters " condition, stop to heat periodic duty, open the magnetic valve 7 of recirculated water bypass, the hot water that Teat pump boiler is produced directly sprays on the evaporating heat exchanger 4, melts the frost on fin and the evaporation coil; When satisfied " defrosting is withdrawed from " condition, close the magnetic valve 7 of recirculated water bypass, recover heating circulation then and work on.
Claims (1)
1. air source hot pump water heater with heat water-spraying's defroster, comprise Teat pump boiler, near the heat water-spraying of the layout pipe of cold wind evaporimeter that it is characterized in that described Teat pump boiler, be used for defrosting to evaporating heat exchanger, the recirculated water delivery side of pump connects a recirculated water bypass and enters described heat water-spraying's pipe, has magnetic valve to be used to control the recirculated water break-make in the recirculated water bypass.
