太阳能和空气能联合供热水、供暖系统方案设计

Preliminary design on solar and air energy joint for hot water and heating system

根据开发商提供的太阳能水箱和集热器的参数,确定了空气能容量及型号、供热末端的选型和负荷计算,并对太阳能、空气能及供热末端热水管道采用的两种循环系统安装方案进行了论述,得出:热水循环系统方案1和热水循环系统方案2在非供暖季节区别不大;在供暖季节,方案1中太阳能作为预热系统,太阳能凉水的补入不影响冬季供暖效果,更优于热水循环系统方案2,因此选择热水循环系统方案1作为实施方案。

The prehmlnary deslgn on solar and mr joint for hot water and heating system was carried out. Based on the solar water heater and solar collector parameters, the air capacity and model, the selection of heating end and the calculation of load are determined. And two kinds of circulation system installation schemes for solar energy, air energy and heating end - heating pipes are discussed. It is con- eluded that the scheme of hot water circulation system 1 and the scheme 2 of hot water circulation system are not very different in non - heating season; In the heating season, in the program 1, when the solar energy serves as a preheating system, solar cold water supple- ment does not affect the effect of heating in winter, hot water system is better than the program 2, so the hot water recycling system 1 is chosen as an implementation plan.
