摘要
作为其核心部件而使被动式太阳能温室运作的一
    种新型太阳能集热调温系统,其性能主要通过冬季实验研究
    确定;温室的耗热量是设计、制作该系统和辅助加热系统的
    基本依据。通过冬季实验,本文研究了温室耗热量的估算方
    法,以及该集热调温系统冬季对温室的增温性能。得到如下
    结论:
    (1)可借鉴建筑采暖设计规范中基本耗热量的计算方法估算
    温室的基本耗热量;
    (2)在昆明地区,当按每平方米温室占地面积配备25kg水
    设计集热调温系统时(热水温度不低于35℃),可以使冬季
    夜间的室温比室外环境温度高4~8℃;若需要将室温维持在
    不低于12℃,其水量配比应不小于50kg/m~2。
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.
