Embodiment 1

[0076] Such as 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 underg...

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.

Abstract

The invention provides a seasonal heat storage and heating system and a heating method of the seasonal heat storage and heating system and relates to the technical field of heat storage and heat supply. The heat storage and heating system comprises a solar heat collector, a buffer water tank, a first heat exchanger, a second heat exchanger and an underground heat storage system. The solar heat collector heats water in the buffer water tank through the first heat exchanger. The underground heat storage system comprises a heat storage pool and first heat exchange coil pipes, all of which are buried in the ground. The first heat exchange coil pipes are arranged around the heat storage pool. The second heat exchanger communicates with the first heat exchange coil pipes through the heat storage pool and used for heating a heat storage medium in the heat storage pool and heating soil around the heat storage pool. By the adoption of the seasonable heat storage and heating system and the heating method, solar heat in the non-heating season is stored through the heat storage pool, the soil around the heat storage pool is heated through the first heat exchange coil pipes arranged around the heat storage pool, and the heat storage of the soil around the heat storage pool is used effectively; and furthermore, heat emitted by the heat storage pool can be used for the second time due to the arrangement of the first heat exchange coil pipes around the heat storage pool, and the system efficiency is provided.

Description

technical field [0001] The invention relates to the technical field of heat storage and heat supply, in particular to a cross-seasonal heat storage and heat supply system and a heating method thereof. Background technique [0002] At present, solar energy is an inexhaustible renewable energy source. With the decrease of fossil fuels and the increasingly severe international energy situation, the development and utilization of solar energy is one of the important ways to realize the diversification of energy supply and ensure energy security. Solar heating is one of the effective ways to reduce the heating coal consumption of buildings in northern my country. [0003] Due to seasonal changes, the efficiency of heat collection systems such as solar energy is different. At the same time, people's demand for hot water and other heat energy also changes in different seasons; The heat collection efficiency is high, but people's demand for hot water and other heating is low; and i...
