Embodiment 1
[0076] like figure 1 As shown, a cross-season heat storage and heat supply system provided in this embodiment includes: a solar collector 10, a buffer water tank 20, a first heat exchanger 11, a second heat exchanger 21, and an underground heat storage system;
[0077] The solar heat collector 10 is connected to the heat source side of the first heat exchanger 11 through a heat collection circulation pipeline 12;
[0078] The heat exchange side of the first heat exchanger 11 is connected with the buffer water tank 20 through the first heat exchange pipeline 13; the solar heat collector 10 heats the water in the buffer water tank 20 through the first heat exchanger 11;
[0079] The heat source side of the second heat exchanger 21 is connected to the buffer water tank 20 through the second heat exchange pipeline 22;
[0080] Both the first heat exchange pipeline 13 and the second heat exchange pipeline 22 are provided with water pumps and control valves;
[0081] The undergrou...
Embodiment 2
[0125] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0126] Among them such as Figure 4 As shown, the heat storage medium is gravel sand 35; the heat storage tank 30 is provided with a second heat exchange coil 36; The heat is obtained from the sand 35 ; the second heat exchange coil 36 is connected with the second heat exchange pipeline 22 .
[0127] The second heat exchange coil 36 includes a hot water port and a cold water port arranged up and down oppositely.
[0128] Compared with Example 1, the heat storage medium in this example is changed to gravel and sand, so that it has a certain pressure bearing capacity, so that the heat storage tank can be placed under roads, buildings, etc., so that no special occupation of land resources is required , which is convenient for popularization and application in cities and other areas where land resources are scarce.
