Description of drawings
Fig. 1 is the structural representation of existing heat pump water heater system;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 2, a kind of heat pump water heater system with the varying capacity water tank, comprise Teat pump boiler main frame 1, pressurized tank 2, also comprise volume-variable water tank 3, these volume-variable water tank 3 bottoms are provided with circulation water inlet 31, circulating outlet 32 and hot water outlet 33, the circulation water inlet 31 of described volume-variable water tank 3 connects the circulating outlet 11 of pressurized tank 2 and Teat pump boiler main frame 1 successively, the circulating outlet 32 of described volume-variable water tank 3 connects the circulation water inlet 12 of Teat pump boiler main frame 1, and is provided with water supplement port 4 before the circulation water inlet 12 of Teat pump boiler main frame 1.
Described volume-variable water tank is horizontal water tank.
After using the water tank of volume-variable, the water tank intake-outlet that circulates is located at the bottom, hot water outlet also is located at water tank bottom, before water supplement port is located at Teat pump boiler circulation water inlet place, installs pressurized tank additional before water tank circulation water inlet.When the user used, hot water constantly flowed out from outlet, and cold water constantly replenishes from water supplement port.Because before water supplement port was located at Teat pump boiler circulation water inlet, water temperature had had certain rising before therefore the cold water that replenishes flowed into water tank, the time of can proper extension hot water using.Generally, the cold water discharge of water supplement port is transferred smallerly, prevents that too much cold water from entering water tank.When the effect of pressurized tank was to use hot water, along with continuously outflowing of hot water, the pressure in the pressurized tank constantly entered water tank at this moment, and the water capacity in the water tank is progressively reduced.When water temperature drops to lower limit temperature, compressor start, heating water tank so moves in circles once more.Can see that in user's use, the water capacity in the water tank is progressively diminishing, promptly the Teat pump boiler water capacity that need heat is also diminishing, thereby has reduced the heat time heating time of Teat pump boiler on the other hand, satisfies the high water temperature requirement of bathing.Water capacity in water tank drops to certain position (be provided with as required, generally be set at the position slightly high apart from the cistern water level minimum point), and system sends certain prompting, stops using Teat pump boiler.At this moment, the hot water in the water tank has used and will use up, and the cold water that replenishes in this process continues to break simultaneously, makes water tank temperature relatively low.Then, regain pressure by pressurized tank, the cold water that replenishes in the water supplement port constantly enters water tank, and system is water filling heating operation again under low water temperature.With the performance of Teat pump boiler, it far above the high water temperature stage, has used the stronger stage of Teat pump boiler unit heating capacity at the heating capacity that hangs down the water temperature stage conscientiously, has reached energy-conservation effect.
To sum up, use the system of the water tank of volume-variable can use the performance advantage that heat pump hangs down the high COP of water temperature section well, and because the pressure in the pressurized tank enters the volume that water tank can reduce to add hot water in good time, thereby reach energy-saving effect preferably.Use the power saving that not only saves time of the heat pump water heater system of varying capacity water tank, and, can adopt horizontal being suspended in the room, reduce floor space, solved the bigger drawback of family expenses unit floor space to a certain extent because the water tank volume significantly reduces.
