Title:
SOLAR GREENHOUSE HEAT STORAGE AND RELEASE SYSTEM AND HEAT STORAGE AND RELEASE METHOD
Document Type and Number:
WIPO Patent Application WO/2021/147399
Kind Code:
A1
Abstract:
A solar greenhouse heat storage and release system and a heat storage and release method. The solar greenhouse heat storage and release system comprises a solar greenhouse (1) constructed on soil, a heat pump unit (2), and a pipe (3). The heat pump unit (2) is provided in the solar greenhouse (1); the pipe (3) used for containing water is laid below a plough layer (4) of the soil, and the heat pump unit (2) is connected to the pipe (3), so that water in the pipe (3) is heated for warming the plough layer (4) of the soil. The heat pump unit (2) is placed in the solar greenhouse (1), when a temperature is high during daytime, excess heat energy in the solar greenhouse (1) in fine weather can be used for warming the soil, and the heat energy is stored in the soil; when the temperature is decreased at night, the heat energy stored in the soil is naturally released to maintain an air temperature in the solar greenhouse (1). The heat storage and release capacity of the soil is improved, the original heat insulation capacity of a rear wall body, a rear slope, and a gable wall is used, an effect of improving a ground temperature and the air temperature at night in the solar greenhouse (1) is achieved, so that planted crops can grow normally.
