End 17 provides the cold water that steady temperature is 7 DEG C.
When summer solar energy is sufficient, solar thermal collector 2 absorbs the water in solar radiation heat cycles pipeline, works as solar energy
During temperature T1 >=22 DEG C in the exit of heat collector 2, the first electric T-shaped valve 4-1 initial steers solar thermal collector 2 is accumulation of heat water
The accumulation of heat of case 12, now solar thermal collector 2, hot water storage tank 12, first circulation water pump 3-1 formation collection thermal cycles.When detecting too
The temperature T1 in positive energy heat collector 2 exit<At 22 DEG C, first circulation water pump 3-1 is out of service.When three-temperature sensor T3 inspections
During temperature T3 >=70 DEG C measured, first circulation water pump 3-1 is out of service.
When useful heat demand, but solar energy heating circulation can't reach and use heat demand, i.e. the temperature of hot water storage tank 12
T3<At 45 DEG C, manually opened electric heater 13, after the temperature of hot water storage tank 12 reaches 45 DEG C, electric heater 13 stops, and meets base
This uses heat demand.The temperature of hot water storage tank 12 can set 45 DEG C -70 DEG C during electrical heating, be added according to different demands lower water temperature electricity
Hot temperature.
When summer meeting refrigeration demand, cold-storage water tank stores enough colds, can also open air source heat pump and heat circulation
Heating domestic hot water.Now compressor 8, four-way reversing valve 7, outdoor heat exchanger 6, choke valve 9, pipe heat exchanger 5 ' are collectively formed
Heat circulation；Pipe heat exchanger 5 ', second circulation water pump 3-2, the formation hot water circuit of hot water storage tank 12.When the temperature of hot water storage tank 12
Reach after 45 DEG C, air source heat pump, which heats circulation, to be stopped, and automatically switches to kind of refrigeration cycle for the cooling water of accumulation of heat/cold-storage water tank 11.
Winter needs that accumulation of heat/cold-storage water tank 11 and hot water storage tank 12 are provided heat to meet the need of heating and domestic hot-water
Ask.Initial launch pattern is that solar thermal collector 2 is that to provide heat and air source heat pump be accumulation of heat/cold-storage water tank to hot water storage tank 12
11 provide heat.When there is heating demands, air source heat pump is opened, the second electric T-shaped valve 4-2 initial steer outdoor heat exchangers
6, now compressor 8, four-way reversing valve 7, outdoor heat exchanger 6, choke valve 9 and pipe heat exchanger 5 ' constitute heat pump and heat circulation.

Stopping is heated.Air source heat pump is being run using paddy electricity, when second temperature sensor T2 detects 2 >=60 DEG C of water temperature T, air
Source heat pump stops heating.
When the first temperature sensor T1 in the exit of solar thermal collector 2 detects exit water temperature T1 >=47 DEG C, air
Source heat pump stops, and solar thermal collector 2 is that accumulation of heat/cold-storage water tank 11 provides heat.When second temperature sensor T2 detects water
During warm T2 >=70 DEG C, first circulation water pump 3-1 is out of service, in order to avoid the accumulation of heat/water temperature over-high of cold-storage water tank 11 influence heat-insulating property.
When the first temperature sensor T in the exit of solar thermal collector 2 detects 12 DEG C≤T1 of exit water temperature<At 22 DEG C,
First electric T-shaped valve 4-1 turns to pipe heat exchanger 5, now solar thermal collector 2, pipe heat exchanger 5 and first circulation water pump
3-1 constitute circulation, pipe heat exchanger 5 as heat pump cycle evaporator, meanwhile, the second electric T-shaped valve 4- in heat pump cycle
2 turn to pipe heat exchanger 5, are that accumulation of heat/cold-storage water tank 11 and hot water storage tank 12 provide heat by air source heat pump.
When the first temperature sensor T1 in the exit of solar thermal collector 2 detects exit water temperature T1<At 12 DEG C, first follows
Ring water pump 3-1 is out of service.Pipe heat exchanger 5 is switched to outdoor heat exchanger 6 in heat pump cycle.
Severe cold weather is run into, the temperature of accumulation of heat/cold-storage water tank 11 can not also expire after air source heat pump runs a period of time
During temperature set by sufficient heating demands, then opening electric heater 13.
45 DEG C of 12 preliminary set time of hot water storage tank, can set 45 DEG C -70 DEG C, when useful heat demand, and solar energy
Collection thermal cycle, which can not be met, uses heat demand, i.e. the water temperature T 3 that three-temperature sensor T3 is detected<At 45 DEG C, air-source heat is utilized
Pump is that hot water storage tank 12 provides heat, is realized by the steering for adjusting the 5th electric T-shaped valve 4-5 to the accumulation of heat of hot water storage tank 12.When
During using air source heat pump for 12 accumulation of heat of hot water storage tank, pause provides heat to accumulation of heat/cold-storage water tank 11, realizes domestic hot-water's
Priority acccess control.Water temperature T 3 can't reach the temperature Td of setting after air source heat pump is run 10 minutes, and electric heater 13 is opened,
By water temperature heating to set water temperature, air source heat pump is converted to accumulation of heat/heat supply of cold-storage water tank 11；If can be heated in 10 minutes
Set water temperature Td, air source heat pump is directly to for accumulation of heat/heat supply of cold-storage water tank 11, and electric heater 13 is without opening.
When the unlatching of electric heater 13 heats for hot water storage tank 12, the 6th electric T-shaped valve 4-6 turns to first circulation water pump 3-
1, prevent the heat for producing electrical heating from taking away.When three-temperature sensor T3 detects T3<At 35 DEG C, the 6th electric T-shaped valve
4-6 turns to hot water storage tank 12 and returns to initial steer.
Above-mentioned embodiment is only the specific case of the present invention, is not the limitation for making other forms to the present invention,
Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent implementations.But on the premise of every principle without departing from the technology of the present invention, the technical spirit according to the present invention is to the above
Any simple modification, equivalent variations and remodeling that embodiment is made, should all fall into the scope of patent protection of the present invention.
