太阳能热泵复合系统应用与节能分析

Application and Energy-saving Analysis of Solar Hea Pump Composite System

本文分析计算了广东某地区一个300间客房的酒店采用太阳能和热泵复合系统供应热水的方案,并且和采用电热水器供热水的方案进行了对比。研究表明,采用太阳能热泵复合系统仅需要18匹的热泵配20平米的太阳能集热器,即可满足每间客房8小时供热水的需求。供应热水的方案无论从初投资还是运行费用以及环保方面,都具有明显的优势。该方案可以为类似热水需求单位提供理论和现实的指导。

This paper analyzes and calculates a solar energy and heat pump composite system with a 300-room hotel in Guangdong Province to supply hot water,and the system is compared with that of using electric water heater.Studies have shown that the composite system only needs 18HP heat pump and 20 square meters of solar collector to meet the demand of hot water for 8 hours per room.The solution of hot water supply has obvious advantages in terms of initial investment,operating costs and environmental protection.This study can provide theoretical and practical guidance for similar hot water demand.
