A STUDY ON THE BASEMENT CLIMATIC ENVIRONMENT IMPROVEMENT BY SOLAR ENERGY

本文分析了地下室的热负荷和太阳能采暖降湿热风系统的供热能力,并以开封市的地下室为例,作了具体计算研究。

Warm and dry in winter but cold and humid in summer are the main features of basement climate, the Latter being the main hindrance to exploit the basement.With plentful solar radiation in summer as heat source and air as conducting medium, and by the use of solar heating and humidity-reducing system and the ventilation equipment in the air-raid shelter, the heated air can be coducted into the basement to warm up it and reduce the humidity, which has proved to be the effective way to solve the cold and humid problem in basement in summer.The key of the system is how to estimate scientifically the value of heat load(W), heat supply capacity (Qs) and the effective heating collect area ( Ac) .The equation of W = W1(heat lost )-Qp ( person's heat rediation) - W (equipment heat radiation)and Q3 = Qd η v, Ac = W/Qs have been used in the paper to calculate the value of W,Qs and Ac.Taking the heating system in Kaifeng air-raid shelter as an example,these values have been made out by these equations.Practice has proved that by the method suggested in this paper,it can not only meet the technical standard, improve the basement climatic environment ,but also feasible economically to design solar heating and humi-dioty reducing system and determine effective heating-collecting area.
