A new kind of solar collecting and temperature-adjusting system is main component of passive solar greenhouse, which is operated by the main component, and the function of the greenhouse is defined by the experiments carried on in winter. The quantity of expended heat is the basic foundation to design and make the system and its auxiliary heating system. The paper has studied the method to estimate quantity of the expended heat of the greenhouse and the function of the temperature of the greenhouse raised by the solar collecting and temperature-adjusting. The results are following: (1)Using the calculating method of the quantity of the basic heat in the book of the building pluck warm design standard for reference, one can estimate the quantity of the basic expended heat of the greenhouse. (2)In Kun Ming district, the inside air temperature can be 4 8 0C higher than the outdoor air temperature at night in winter, if the solar collecting and temperature-adjusting system is designed according to 25kg/in2 of water quantity distribution(the temperature of the heat water is above 35 0C). Wanting to keep the inside air temperature higher than 10 慍, we must keep the distribution more than 5 0kg/rn2.
Keywords/Search Tags:solar greenhouse, quantity of the expended heat, solar collecting and temperature-adjusting system, winter.
