Description
Technical field
the utility model relates to a kind of air-source water heater, especially a kind of once-through cycle formula air-source water heater.
Background technology
enter 21 century, along with the fast development of economy and people live improving constantly of grade, hot water for life has become the daily necessities of people.At present, widely used hot water apparatus mainly contains gas fired-boiler, coal-burning boiler, oil burning boiler and electric heater unit.These devices not only will consume a large amount of matchmaker's resources or fuel resource or electric power resource, and the environment of returning had causes pollution in various degree.The heat pump water heater utilizing compressor to heat is development in recent years new technology faster.Existing Teat pump boiler is generally single heat source Teat pump boiler, utilizes air as thermal source, by consuming a small amount of electrical energy drive compressor work, the Energy extraction deposited in air out, for heating water, therefore also referred to as air-source water heater.
But existing air-source water heater on market, especially for the water heater of static state heating, when the hot water in water tank is not enough, now needs from extraneous amount of makeup water.Current is directly the cold water in the external world or normal-temperature water are first inputted in water tank to mix with hot water original in water tank, and then start unit the water in water tank is heated, this kind of heat form, easily phenomenon uneven in temperature is there is in water tank, cause by water effect poor, impact normally uses.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of once-through cycle formula air-source water heater, by the circulating-heating voluntarily of the water in heat storage water tank, and the running water in the external world first heated after enter heat storage water tank again, ensure that even water temperature is consistent.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of once-through cycle formula air-source water heater, comprise heat pump assembly and heat storage water tank, the delivery port of described heat storage water tank is connected with heat pump assembly by outlet pipe, and the water inlet of heat storage water tank is connected with heat pump assembly by return duct, also comprise water inlet pipe, this water inlet pipe is connected with outlet pipe.
Described heat pump assembly comprises the compressor, hot water heat exchanger, throttling arrangement, the evaporimeter that are linked in sequence successively by pipeline, and tieback is to compressor again for evaporimeter, and outlet pipe is connected with hot water heat exchanger respectively with return duct.
Described evaporimeter is finned evaporator, is also provided with blower fan at this finned evaporator place.
Described outlet pipe is provided with water circulating pump.
Described outlet pipe is also provided with check valve, makes the water on outlet pipe can only flow to hot water heat exchanger by heat storage water tank.
Described water inlet pipe is provided with water flow switch and check valve, makes water inlet pipe can only flow to hot water heat exchanger.
The utility model compared with prior art has following beneficial effect:
When system water, compressor start, water circulating pump is inoperative, and running water first exports hot water through heat storage water tank again after hot water heat exchanger once heats; During without water, when heat storage water tank temperature is lower than design temperature, water circulating pump and compressor start, carry out circulating-heating to design temperature to the water of heat storage water tank, store for future use.Avoid when using water, tap water direct taps into and mixes with original hot water into heat storage water tank, occurs phenomenon uneven in temperature.

Accompanying drawing 1 is the utility model pipeline catenation principle schematic diagram;
Structural representation when accompanying drawing 2 is the utility model DC heating;
Structural representation when accompanying drawing 3 is the utility model circulating-heating.
In above figure, the direction of arrow represents the flow direction of material.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of once-through cycle formula air-source water heater, comprise heat pump assembly and heat storage water tank 6, the delivery port of described heat storage water tank 6 is connected with heat pump assembly by outlet pipe 12, the water inlet of heat storage water tank 6 is connected with heat pump assembly by return duct 13, also comprise water inlet pipe 11, this water inlet pipe 11 is connected with outlet pipe 12.Heat pump assembly comprises the compressor 1, hot water heat exchanger 2, throttling arrangement 3, the evaporimeter 4 that are linked in sequence successively by pipeline, and tieback is to compressor 1 again for evaporimeter 4, and outlet pipe 12 is connected with hot water heat exchanger 2 respectively with return duct 13.Compressor, hot water heat exchanger, connecting line between throttling arrangement and evaporimeter are the heat transfer pipe for refrigerant flowing.
Evaporimeter is finned evaporator, is also provided with blower fan, draw heat from air at this finned evaporator place, increases heat.
Outlet pipe 12 is provided with water circulating pump 7, the water in heat storage water tank 6 is extracted and is delivered to hot water heat exchanger 2.Outlet pipe 12 is also provided with check valve 8, make the water on outlet pipe 12 can only flow to hot water heat exchanger by heat storage water tank, and water can not flows back in heat storage water tank from outlet pipe.
Water inlet pipe 11 is provided with water flow switch 9 and check valve 10, makes water inlet pipe 11 can only flow to hot water heat exchanger, also makes water can not backflow away from water inlet pipe.
When the water level in heat storage water tank is lower, now need, from extraneous amount of makeup water, to utilize the microcomputer control system of peripheral hardware, when the system of detecting meets executive condition, water heater automatically switches to DC heating pattern.As shown in Figure 2, start compressor, hot water now in heat storage water tank can not be drawn out of, extraneous running water enters from water inlet pipe and enters into hot water heat exchanger, compressor 1 discharges heat energy by sending in hot water heat exchanger 2 after refrigerant compression, the water entering into hot water heat exchanger then absorbs this heat makes water temperature raise, and the water after heating enters into heat storage water tank again for use.Refrigerant to enter in evaporimeter 4 after throttling arrangement 3, is run the heat energy absorbed in air by blower fan 5, then returns in compressor 1 and enter next circulation.
As shown in Figure 3, when the water level in heat storage water tank is higher than designated water level line, water inlet pipe is closed.Now utilize the microcomputer control system of peripheral hardware, when detecting that the water in heat storage water tank 6 is lower than design temperature, i.e. start cycles water pump 7 and compressor 1, water circulating pump 7 drives the water in heat storage water tank 6 to circulate in outlet pipe 12 and return duct 13 as active force, compressor 1 discharges heat energy by sending in hot water heat exchanger 2 after refrigerant compression, thus heating is from the water of heat storage water tank 6.Refrigerant enters in evaporimeter 4 after throttling arrangement 3, runs by blower fan 5 heat energy absorbed in air, then returns in compressor 1 and enter next circulation.Until the water in heat storage water tank 6 be heated to design temperature after unit out of service.
The utility model is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
