When the second temperature sensor 63 detects that the temperature of the water in the heat collecting water tank 6 is lower than a seventh set value (e.g., 5-10 ℃), the controller 9 controls the bidirectional water pump 81 to be turned on in the reverse direction to feed the water of higher temperature in the heat storage water tank 8 into the heat collecting water tank 6, so as to prevent the water in the heat collecting water tank 6 from freezing.
The controller also controls the on and off of the heat pump according to signals detected by the first and second water level sensors and the second and third temperature sensors,
when the second temperature sensor 63 detects that the temperature of the water in the heat collecting water tank 6 is lower than a first set value, that is, the heat collecting water tank 6 cannot take water from the heat collector R, the controller 9 controls the ground source heat pump to start, so as to transfer the underground heat to the heat storage water tank 8 for heating the water in the heat storage water tank 8;
when the first water level sensor detects that the water level in the heat collection water tank 6 reaches a second set height, the controller 9 controls the water source heat pump to operate, absorbs heat in the heat collection water tank 6, heats water in the heat storage water tank 8 after the heat collection water tank is lifted, and when the third temperature sensor detects that the water temperature in the heat storage water tank 8 reaches a sixth set value, the water source heat pump is controlled to stop operating.
When the first water level sensor detects that the water level in the heat collecting water tank 6 reaches a third set height (for example, the heat collecting water tank 6 is full of water), the second water level sensor 86 detects that the water level in the heat storage water tank 8 reaches the second set height, the second temperature sensor detects that the water temperature in the heat collecting water tank 6 reaches a first set value, and the third temperature sensor 85 detects that the water temperature in the heat storage water tank 8 reaches a fifth set value, that is, when the heat collecting water tank 6 and the heat storage water tank 8 are full of water and the water temperatures in the heat collecting water tank 6 and the heat storage water tank 8 are higher, the controller 9 controls the ground source heat pump to operate, so that the ground source heat pump 83 transfers the heat in the heat collecting water tank 6 to; and when the water temperature in the heat collecting water tank 6 reaches the second set value, the ground source heat pump 83 stops running. The situation generally occurs in summer, so that when the water temperature of the heat collector R reaches 25 ℃, the circulating water pump 62 can pump water with lower temperature in the heat collecting water tank 6 into the heat collector R, so that the solar photovoltaic power generation assembly 1 can keep an ideal power generation temperature;
when the first water level sensor detects that the water level in the heat collecting water tank 6 reaches the third set height, the second water level sensor 86 detects that the water level in the heat storage water tank 8 reaches the second set height, and the second temperature sensor detects that the water temperature in the heat collecting water tank 6 is lower than the seventh set value, that is, when the water in the heat collecting water tank 6 and the heat storage water tank 8 is full and the water temperature in the heat collecting water tank 6 is lower, the controller 9 controls the ground source heat pump to operate, so as to absorb the underground heat source and heat the water in the heat collecting water tank 6. This situation generally occurs in winter or cloudy days, so that the temperature of the water in the heat collecting water tank 6 can be raised to prevent the water therein from being frozen, and further, the water heated in the heat collecting water tank 6 can be pumped into the heat collector R through the circulating water pump 62 to prevent the water in the heat collector R from being frozen.
When the third temperature sensor 85 detects that the temperature of the water in the hot water storage tank 8 still does not reach the fifth set value (for example, 60 ℃) after the set time is reached, the controller 9 controls the ground source heat pump to operate, so as to absorb the underground heat source and heat the water in the hot water storage tank 8 by using the underground heat source until the temperature of the water rises to the sixth set value (for example, 60 ℃), and then the controller 9 controls the ground source heat pump to stop working.
In the above embodiment, the water in the hot water storage tank 8 can be provided for use in life and production.
