Specific embodiment
With reference to the accompanying drawings and examples this utility model is further described.
As shown in Figure 1.
It is a kind of can highly effective defrosting the circulating air-source heat pump hot water of directly-heated, including by compressor 1, cross valve 2, water side
The refrigerant-cycle systems of heat exchanger 3, electric expansion valve 4, air-side heat exchanger 5 and gas-liquid separator 6 composition.The water side is changed
Water route and the water inlet and outlet for external water turnover are provided with hot device 3, make external water source enter in the water-side heat 3 with
Cold-producing medium carries out heat exchange, so as to obtain hot water.The water inlet connects directly-heated water inlet pipe 10 and circulation water inlet pipe 13 simultaneously；Institute
State directly-heated water inlet pipe 10 and be provided with directly-heated check valve 9, electromagnetic valve 8 and Water flow adjusting valve 7, the break-make of water can be controlled, and
Adjust the size of current.The circulation water inlet pipe 13 is provided with circulation check valve 12 and water circulating pump 14, and the circulation water inlet
Pipe 13 connects storage tank 15, the water in storage tank 15 can be delivered to the water inlet by water circulating pump 14.The water outlet
Mouthful by outlet pipe 11 connect storage tank 15, make through heat exchange water energy enough first deposit in the storage tank 15, facilitate user with
When take.
The conducting direction of the directly-heated check valve 9 and circulation check valve 12 is sensing water inlet, can avoid in water route
Occurs the phenomenon for flowing backwards during switching.
The connection tap water of directly-heated water inlet pipe 10 water pipe 16, can be used directly the operation that tap water participates in directly-heated pattern.
Running of the present utility model is：
When unit normally runs directly-heated pattern, coolant enters water-side heat through cross valve after compressor compresses,
Exchanged heat with the external water through water-side heat, then after electric expansion valve throttling, air inlet side heat exchanger, with
Air is exchanged heat, the heat in draw air, then after cross valve and gas-liquid separator, is pressed by compressor suction
Contracting, forms refrigerant circulation.Meanwhile, tap water enters directly-heated water inlet pipe by tap water pipe flow, and is adjusted by Water flow adjusting valve
After amount of restriction, become hot water after heat exchange being carried out into water-side heat and coolant system, then water storage box is flowed into by outlet pipe
Storage.
During winter operation, if air-side heat exchanger fin surface be less than 0 DEG C, unit operation for a period of time after, the sky
On the heat exchanger fin of gas side, meeting frosting, declines unit performance.Now, unit operation defrosting mode：First waterway switching system, opens
Water circulating pump is opened, the hot water of water storage box is entered into water-side heat by circulation water inlet pipe.After operation a period of time, directly-heated is closed
Electromagnetic valve on water inlet pipe, prevents tap water from entering water-side heat by directly-heated water inlet pipe.Meanwhile, switching four-way Vavle switching is cold
Matchmaker's system, makes coolant after compressor compresses, and through cross valve air inlet side, heat exchanger carries out heat release, and the air side is changed
Frost removing on hot device fin.Then, throttle through electric expansion valve, into water-side heat, the draw heat from recirculated water,
Again after cross valve and gas-liquid separator, it is compressed by compressor suction, forms the defrosting circulation of coolant.
After defrosting terminates, then directly-heated pattern is switched back into, specially first waterway switching system, opens solenoid valve allow tap water
Into water-side heat, simultaneously close off water circulating pump and switch to directly-heated water route.Switch cross valve simultaneously, enter coolant system straight
The refrigerant circulation of heat pattern.
This utility model is realized in the case of compressor is non-stop-machine by switching water system and coolant circulating system,
Quickly defrosting is carried out, makes the operation of unit more efficiently and reliable.
This utility model is not directed to partly same as the prior art or can be realized using prior art.
