This is because the internal thermal insulation system effectively prevented heat loss inside the greenhouse. The temperature of the air below the internal thermal insulation system can be maintained at a high level because the air below the system has a heating source (water heat storage system) that continuously releases heat.
Water absorbed solar energy through heat collector system and stored heat in heat storage system during the daytime, and released heat into the greenhouse through convection heat transfer at night. The envelope structure of greenhouse conducted energy in five ways: soil, south roof, north roof, wall and internal thermal insulation system.
The demand for the quality and yield requirements of crops in high latitudes and cold regions is increasing. The traditional structure design of the Chinese solar greenhouse (CSG) can't meet the needs of over-winter production of warm-season crops, the thermal insulation and heat storage capacity of the CSG need to be further improved.
Fig. 4 shows the thermal energy exchange of the new greenhouse involved incoming solar radiation during the daytime and greenhouse energy consumption. Greenhouse energy consumption was categorized into four modules: air temperature altering energy, convection energy, conduction energy and ventilation energy.
In response to the problems of passive heat storage, many scholars have introduced active heat storage technology into solar greenhouses to further improve solar energy utilization,
