Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1As shown, the solar interseasonal soil energy storage heating system is collected by the solar collector 19 installed on the heating building 18. When the spring, summer, autumn, non-heating season and winter sunshine are sufficient, the excess heat collected by the solar collector 19 is Water or air is used as the heat transfer carrier, and the valve is controlled by the controller 16 and injected into the heat storage tank 7 for heat storage through the transmission pipeline; figure 2 As shown, the heat storage tank 7 is composed of a plurality of heat exchange wells 2. The heat exchange wells 2 are built with U-shaped heat exchange tubes 1, and the U-shaped heat exchange tubes 1 transfer heat to the soil through water or air. The heat energy is stored in the soil between the wells 2, and water or air is pum...

Abstract

The invention relates to the technical field of solar heat utilization, in particular to a solar cross-quarter soil energy storage and heating supply system. The system comprises a solar heat collector arranged in a heating building, a radiator arranged in the heating building, a heat storage tank arranged under the earth surface, a transmission pipeline communicating with the solar heat collector, the radiator and the heat storage tank, a heat transfer carrier arranged in the transmission pipeline and the like. The heat storage tank is composed of heat exchange wells distributed radially fromthe center. U-shaped heat exchange tubes are arranged in the heat exchange wells. The upper ends of the U-shaped heat exchange tubes are connected in series through buried collecting tubes. The depthof the heat exchange wells is 30-50 m. Compared with a ground source heat pump soil heat storage method, the occupied area is reduced by 70%, the manufacturing cost is reduced by 40%, the heat storage time is shortened by 50%, the heat supply temperature is increased by 12-15 DEG C during the same period, the heat supply time is prolonged by 1.5-1.8 times, and economic benefits and the thermal performance index are both substantially improved.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization, and is especially suitable for heating in winter in most parts of North China, and in particular relates to a solar energy cross-seasonal soil energy storage heating system. Background technique [0002] At present, the bottleneck of smog reduction in northern China is the emission of coal-fired heating in winter. Using solar energy as an auxiliary heating energy is a powerful measure to solve the cause of smog. The long-term economic benefits, ecological and social benefits are significant. But because the solar energy system is restricted by weather and night, it is impossible to work around the clock. At present, the use of solar energy for heating must be equipped with other auxiliary energy sources and corresponding equipment. In order to solve the problem of effective utilization of solar energy in the heating season, various energy storage technologies supporting solar therm...
