Abstract:
In order to solve the storage heat increase cooling equipment suitable for solar greenhouses in southern Xinjiang and improve the ability of solar greenhouses to resist midday high temperature and night low temperature，an active heat storage system for surface air cooler was innovated.The system was installed in a solar greenhouse for operation tests，and the performance of the system such as heat storage，warming air，cooling air，warming nutrient solution and heat storage efficiency were analyzed.The results showed that the heat storage and heat discharge of the active heat storage system of the surface air cooler were 248.640 MJ and 139.776 MJ，respectively.The average temperature of indoor air during midday heat storage was 3.5 ℃ lower than that of controlled greenhouse.The air temperature in the greenhouse was 3 ℃ higher than that of the controlled greenhouse during the night heat release phase.Through data analysis，it could be seen that the heat storage efficiency of the active heat storage system of the surface air cooler was 89.4%.In short，the effect of the active heat storage system of the surface air cooler in the solar greenhouse was more obvious，and the system had a certain generalization significance in the southern Xinjiang region.
