The specific working principle is:

In summer, the room needs to be cooled, and this part of the cooling capacity is provided by the air source heat pump. The second electric three-way valve 4-2 initially turns to the outdoor heat exchanger 6. At this time, the compressor 8, the four-way reversing valve 7, and the outdoor heat exchanger 6. Throttle valve 9, tubular heat exchanger 2 5' form a refrigeration cycle; tubular heat exchanger 2 5', heat storage/cold storage water tank 11, and second circulating water pump 3-2 form a cold water cycle. When the second temperature sensor T2 detects that the water temperature T2 of the heat storage/cool storage water tank 11 is greater than or equal to 7° C., the heat pump starts a refrigeration cycle to provide cold water for the air conditioner terminal 17 . When the second temperature sensor T2 detects that the water temperature of the cold storage water tank is T2<6°C during the peak power period (T2<4°C during the valley power period), the heat pump stops. Use the valley power at night for cold storage to reduce the peak power usage during the day.

The automatic water mixing valve 14, the terminal circulating water pump 15 and the thermostat 16 constitute the water mixing center. The thermostat 16 detects the water supply temperature Tg. When Tg>7°C, the automatic water mixing valve 14 controls the opening and closing angle of the valve to decrease for The amount of return water mixed with cold water, when Tg<7°C, the automatic water mixing valve 14 controls the opening and closing angle of the valve to increase the amount of return water mixed with cold water to provide cold water with a constant temperature of 7°C for the air-conditioning terminal 17.

When the solar energy is sufficient in summer, the solar heat collector 2 absorbs solar radiation to heat the water in the circulation pipeline. When the temperature T1 at the outlet of the solar heat collector 2 is ≥ 22°C, the first electric three-way valve 4-1 initially turns to the solar collector. The heater 2 stores heat for the hot water storage tank 12. At this time, the solar heat collector 2, the hot water storage tank 12, and the first circulating water pump 3-1 form a heat collection cycle. When it is detected that the temperature T1 at the outlet of the solar heat collector 2<22°C, the first circulating water pump 3-1 stops running. When the temperature T3 detected by the third temperature sensor T3 is greater than or equal to 70° C., the first circulating water pump 3 - 1 stops running.

When there is a useful heat demand, but the solar heat collection cycle cannot meet the heat demand, that is, when the temperature T3 of the heat storage tank 12 is <45°C, the electric heater 13 is manually turned on, and when the temperature of the heat storage tank 12 reaches 45°C , the electric heater 13 is stopped to meet the basic heat demand. During electric heating, the temperature of the hot water storage tank 12 can be set at 45°C-70°C, and the electric heating temperature can be adjusted according to different demands.

When the cooling demand is met in summer, the cold storage water tank stores enough cold energy), and the air source heat pump heating cycle can also be turned on to heat domestic hot water.

In winter, it is necessary to provide heat to the heat storage/cool storage tank 11 and the hot water storage tank 12 to meet the demand for heating and domestic hot water. The initial operation mode is that the solar thermal collector 2 provides heat for the heat storage tank 12 and the air source heat pump provides heat for the heat storage/cold storage water tank 11 . When there is a demand for heating, the air source heat pump is turned on, and the second electric three-way valve 4-2 initially turns to the outdoor heat exchanger 6. At this time, the compressor 8, the four-way reversing valve 7, the outdoor heat exchanger 6, and the throttle valve 9 and tubular heat exchanger two 5' form a heat pump heating cycle. Heat is provided to the heat storage/cold storage water tank 11 and the hot water storage tank 12 respectively by switching the fourth electric three-way valve 4-4 and the fifth electric three-way valve 4-5.

When the first temperature sensor T1 at the outlet of the solar collector 2 detects that the outlet water temperature T1≥22°C, the first electric three-way valve 4-1 initially turns to the hot water storage tank 12.

When the air source heat pump is operated with valley electricity, when the second temperature sensor T2 detects that the water temperature T2 is greater than or equal to 60° C., the air source heat pump stops heating.

When the first temperature sensor T1 at the outlet of the solar collector 2 detects that the outlet water temperature T1≥47°C, the air source heat pump stops, and the solar collector 2 provides heat for the heat storage/cool storage water tank 11 . When the second temperature sensor T2 detects that the water temperature T2 is greater than or equal to 70° C., the first circulating water pump 3 - 1 stops running, so as to prevent the thermal insulation performance from being affected by the high water temperature of the heat storage/cold storage water tank 11 .

When the first temperature sensor T at the outlet of the solar collector 2 detects that the outlet water temperature is 12°C≤T1<22°C, the first electric three-way valve 4-1 turns to the tubular heat exchanger 15, and the solar heat collector 2, tubular heat exchanger 15 and the first circulating water pump 3-1 form a cycle, and tubular heat exchanger 15 is used as the evaporator of the heat pump cycle, and at the same time, the second electric three-way valve 4-2 in the heat pump cycle Turning to tube heat exchanger one 5, the air source heat pump provides heat for heat storage/cold storage water tank 11 and hot water storage tank 12 .

In severe cold weather, when the temperature of the heat storage/cold storage water tank 11 cannot meet the temperature set by the heating demand after the air source heat pump has been running for a period of time, the electric heater 13 is turned on.

The initial setting temperature of the hot water tank 12 is 45°C, and it can be set at 45°C-70°C. When there is a useful heat demand, and the solar heat collection cycle cannot meet the heat demand, that is, the water temperature T3 detected by the third temperature sensor T3< At 45°C, the air source heat pump is used to provide heat for the heat storage tank 12, and the heat storage in the heat storage tank 12 is realized by adjusting the steering of the fifth electric three-way valve 4-5. When the air source heat pump is used to store heat in the hot water storage tank 12, the heat supply to the heat storage/cold storage water tank 11 is suspended to realize priority control of domestic hot water. When the water temperature T3 cannot reach the set temperature Td after the air source heat pump runs for 10 minutes, the electric heater 13 is turned on to heat the water temperature to the set water temperature, and the air source heat pump is converted to heat storage/cold storage water tank 11 for heat supply; if 10 minutes The inside can be heated to the set water temperature Td, and the air source heat pump is directly turned to provide heat for the heat storage/cold storage water tank 11, and the electric heater 13 does not need to be turned on.

When the electric heater 13 is turned on to heat the heat storage tank 12, the sixth electric three-way valve 4-6 turns to the first circulating water pump 3-1 to prevent the heat generated by the electric heating from being taken away. When the third temperature sensor T3 detects that T3<35°C, the sixth electric three-way valve 4-6 turns to the hot water storage tank 12 and returns to the initial turning.
