Rural active solar heat storage floor system

[0016] Such as Figure 1~3 As shown, a rural active solar heat storage ground system consists of four parts: a solar heat collection system, a hot water storage tank 4, a geothermal buried pipe heating system, and a heat storage ground 11, including a solar heat collector 1, a heat collector Water outlet pipe 2, heat exchange coil of hot water storage tank 3, hot water storage tank 4, collector water inlet pipe 5, solar collector heat pump 6, solar collector probe temperature sensor T17, water supply pipe 8, water supply pipe 9 , heat storage and heat exchange coil 10, heat storage floor 11, hot water circulation pump 12, return pipe 13, temperature sensor T214 of the hot water storage tank, leveling layer 15, building body 16, kang 17, and regulating valve 18. Before the winter heating season, the heat collected by the solar collector 1 heats the water in it, and under the action of the solar collector heat pump 6, the heated water passes through the collector outlet pipe 2, the

[0018] Such as Figure 2~3 As shown, the thermal storage ground 11 in the rural active solar thermal storage ground system is transformed from the traditional ground in rural residential buildings. First, cement is used for leveling to form a leveling layer 15, and a moisture-proof layer is firstly installed on the upper part of the leveling layer 15. 23. The purpose of the moisture-proof layer 23 is to prevent the lower part of the ground from getting wet, and a plastic film is selected for moisture-proof treatment. What is located at the top of the moisture-proof layer 23 is the thermal insulation layer 22, the material of the thermal insulation layer 22 is selected polystyrene foam board, the clay layer 21 is set on the thermal insulation layer 22 top, and the purpose of the thermal insulation layer 22 is set at the bottom of the clay layer 21 is to prevent heat from being transmitted downwards. The clay layer 21 is made of clay with low heat transfer and easy to form in rural a

[0020] Such as figure 1 As shown, the operation control of the whole system changes the traditional way of single temperature value control, and realizes the control and adjustment of the whole system through the combination of temperature change trend and temperature range. The probe temperature sensor T17 of the solar collector and the temperature sensor T214 of the hot water storage tank control the operation of the solar collector heat pump 6 and the hot water circulation pump 12 respectively through the combination of the temperature change trend and the temperature range. When the needle temperature sensor T17 does not change or rises and the temperature of the solar collector probe temperature sensor T17 is lower than the control temperature, the solar collector heat pump 6 remains closed; when the solar collector probe temperature sensor T17 does not change or rises and the solar collector When the temperature of the collector probe temperature sensor T17 is higher than o
