Abstract
The utility model relates to a variable cycle water flow air source heat pump water heater, wherein an outlet of a circulating water pump is connected with a regulating valve which can regulate the flow rate of circulating-cooling water to fully utilize the cooling capacity of cooling water, and adopt variable cycle water circulation to regulate condensation pressure, thereby improving heating efficiency, and being stable and reliable in work.
Description
Technical field
The utility model relates to a kind of air source hot pump water heater, particularly relates to controlling the air source hot pump water heater of condensing pressure by regulating circulating water flow.
Background technology
Air source hot pump water heater is in kind of refrigeration cycle parameter area allowable, improve the hot water temperature who produces, general bigger water-cooled condenser and the bigger cooling water circular flow of adopting, like this when relatively low especially winter of cooling water temperature, the air source hot pump water heater condensing pressure is just lower, and influence heats the reliability service of circulation.
Summary of the invention
The utility model be at the air source hot pump water heater condensing pressure cross the problem of the reliability service that low directly influence heats circulation and propose to become circulating water flow air source hot pump water heater, make full use of the cooling capacity of cooling water, adopt flow-changing water to circulate and regulate condensing pressure, improve heating efficiency, working stability is reliable.
The technical solution of the utility model is a kind of air source hot pump water heater with condensation pressure regulation, comprises Teat pump boiler, and the recirculated water delivery side of pump in the Teat pump boiler connects a control valve, can regulate circulating cooling water flow.Described water circulating pump is selected velocity fluctuation pump or water pump group for use.
The beneficial effects of the utility model are: make full use of the cooling capacity of cooling water, adopt flow-changing water to circulate and regulate condensing pressure, improve heating efficiency, working stability is reliable.
Description of drawings
Fig. 1 is the air source hot pump water heater structured flowchart that the utility model becomes circulating water flow.
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 connects a control valve 7 in the outlet of water circulating pump 5, regulate circulating cooling water flow by regulating its aperture, the recirculated water of air source hot pump water heater is heated to design temperature (as 60 ℃) from environment temperature always, condensing pressure is too low in the time of should preventing in the work that circulating water temperature is low, condensing pressure is too high when preventing again that circulating water temperature is high, for this reason, adopts the flow-changing water circulation, when circulating water temperature is low, the recirculated water low discharge; When circulating water temperature is high, the big flow of recirculated water.Improve condensing pressure with respect to utilizing hot and cold water to mix the raising circulating water temperature, the circulation of unsteady flow amount cooling water has made full use of the cooling capacity of cooling water, heats the efficient height of circulation.
Water circulating pump 5 selects for use velocity fluctuation pump or water pump group to regulate the effect that circulating cooling water flow all can reach the unsteady flow amount in addition, if use 2-3 water pump to control the number of running water pump according to water temperature, and can also mutual emergency power during emergency.
Claims (3)
1, a kind of air source hot pump water heater that becomes circulating water flow comprises Teat pump boiler, it is characterized in that the recirculated water delivery side of pump in the Teat pump boiler connects a control valve, can regulate circulating cooling water flow.
2, the air source hot pump water heater of change circulating water flow according to claim 1 is characterized in that described water circulating pump selects velocity fluctuation pump for use.
