process 1: solar energy antifreeze solution collection heat transmission circulation system: when sunlight exists, the circulating pump M1 starts to circulate the antifreeze in the pipelines 403 and 404 to send the heat collected by the solar heat collecting plate 4A to the plate heat exchanger 4B, so that heat collection is realized;
and (2) a process: solar heat transfer circulation system: after heat is accumulated in the plate heat exchanger 4B, the heat of the plate heat exchanger 4B is pumped to the coupling water tank 2A through circulating pipes 401 and 402 by a circulating pump M2, so that the heat accumulated by solar energy is transferred to the coupling water tank 2A;
and 3, process: soil energy storage district and coupling water tank heat transfer circulation system: along with the continuous accumulation of the heat of the coupling water tank 2A, when the temperature of the coupling water tank 2A is 10 ℃ higher than that of the soil energy storage area 1, the heat of the coupling water tank 2A is pumped to the soil energy storage area for storage through a circulating pump M3 by a pipeline 201, a water collector and water collector switching valve S1, a pipeline 101, the soil energy storage area 1, a pipeline 102, a water collector and water collector switching valve S2 and a pipeline 202, so that the heat of the coupling water tank is transferred to the soil energy storage area 1 for storage; on the contrary, when the temperature of the soil energy storage area 1 is 5 ℃ higher than that of the coupling water tank 2A, the heat is supplied from the soil energy storage area 1 to the heat storage water tank 2A through the soil energy storage area 1, the pipeline 101, the switching valve S1 of the water collecting and distributing device, the pipeline 201, the coupling water tank 2A, the pipeline 202, the water collecting and distributing device S2 and the pipeline 102 to the soil energy storage area 1 under the action of the circulating pump M3;

and (5) a process: heat transfer and warm-up circulation system of evaporator and condenser: when the heat pump machine 3A operates, fluorine circulation is performed, the water flow heat of the evaporator 301 evaporates and gasifies low-temperature and low-pressure liquid refrigerant, the heat pump machine 3A compresses and applies work to the gasified refrigerant by consuming a small amount of electric power to form high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gaseous refrigerant is sent to the condenser 302, the refrigerant is condensed into high-pressure liquid refrigerant after the water flow of the condenser 302 absorbs heat and is heated, the liquid refrigerant circulates to the interceptor and is intercepted into low-pressure liquid refrigerant, the low-pressure liquid refrigerant is then sent to the evaporator 301 to absorb heat and gasify the low-;
and 6, a process: condenser and coupling water tank heat transfer cycle system: when the heat pump machine 3A is operated, the water flow on the condenser 302 side starts to circulate, and the heat of the condenser 302 is transferred to the coupling water tank 2A by the circulation pump M4 through the condenser 302, the pipeline 303, the coupling water tank 2A, the pipeline 304 and the condenser 302;
and (7) a process: a heat transfer system coupling the water tank and the fan coil: when the fan coil 5A operates, water flow returns to the coupling water tank 2A from the coupling water tank 2A through the circulating pump M5 through the pipeline 305, the fan coil 5A and the pipeline 306, so that heat of the coupling water tank 2A is transferred to the fan coil 5A;
and (8) a process: the processes 1, 2 and 3 are operated in a linkage manner, so that heat storage of the solar heat collecting plate 4A to the soil energy storage area 1 can be realized, it is pointed out that the solar heat collecting plate is firstly stored in the central energy storage area 1A, the valve A of the water collector S1 is opened in the process, and other valves B, C, D and E are closed, because the energy storage of the central energy storage area is limited, when the heat of the solar heat collecting plate is larger than the heat storage amount of the central energy storage area, the valve A of the water collector S1 is closed, and the valves B, C, D and E of any water collector S1 are opened, so that the energy is stored in any peripheral heat preservation area;
and a process 9: in the earlier stage of heat supply, when the temperature of the central energy storage area 1A or the peripheral heat preservation area 1B is higher than that of the coupling water tank 2A, the heat supply from the soil energy storage area 1 to the coupling water tank 2A can be realized by directly operating the process 3 when the heat supply is directly supplied to the coupling water tank.
The process 10: in the later stage of heat supply, when the temperature of the central energy storage area 1A or the peripheral heat preservation area 1B is lower than 40 ℃ and does not meet the heat supply temperature of the coupling water tank, the processes 4, 5 and 6 are operated in a linkage manner, so that the temperature of low-temperature heat released by the central energy storage area 1A or the peripheral heat preservation area 1B can be increased to be higher than 45 ℃ through a heat pump, and then heat is supplied to the coupling water tank 2A. This mode of operation can be used to achieve cold accumulation in the central energy storage region 1A or the peripheral insulation region 1B for cooling purposes in items requiring cooling;
the process 11: when the heat of the peripheral heat preservation area 1B needs to be prevented from being dissipated to the periphery or the heat of the peripheral heat preservation area 1B needs to be transferred and collected to the central energy storage area 1A, the heat of the peripheral heat preservation area 1B can be transferred to the central energy storage area 1A through the process 4, the process 5, the process 6 and the process 3 in sequence and linkage operation.
In the whole energy storage process of the central energy storage area 1A and the peripheral heat preservation area 1B of the energy storage areas, as the heat is preserved by using the surrounding soil, the heat stored in the central energy storage area 1A can be dissipated to the surrounding soil to form a plurality of concentric circle temperature difference layers which radiate outwards by taking the central energy storage area 1A as a circle center, in order to reduce the heat dissipation in the central energy storage area 1A, the heat pump machine 3A extracts the heat dissipated in the soil of the peripheral heat preservation area 1B and sends the heat back to the central energy storage area 1A through the operation mode of the process 11. To reduce heat dissipation, the conventional passive heat preservation is changed into active heat preservation, and it can be seen from fig. 4 that the energy storage temperature of the central energy storage area 1A can be maintained relatively stable with less power consumption.
In particular, the switching valves at S1, S2, S3 and S4 in fig. 1 are A, B, C, D and E from top to bottom, and can be opened and closed according to the operation requirement to switch the water flow of the central energy storage area 1A or the peripheral heat preservation area 1B.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
