多源互补生活热水热源系统在酒店节能中的应用研究

Study on the Application of Multi-energy Complementary Living Hotwater Heating System Available for Hotel Energy Conservation

生活热水热源系统是酒店实现节能的关键系统之一,热源利用形式多种多样,废热余热的回收及天然热源的利用是降低热水加热能耗的重要措施。针对杭州的气象条件,在分析各种热源利用特性的基础上,梳理热源结构并充分考虑季节及温度变化条件下各类热源的性能优势,提出结合太阳能、空气源热泵与冷凝锅炉的多源互补生活热水热源形式,在满足使用条件下对热源配置进行合理优化,以降低运行能耗,为酒店生活热水节能改进提出一种可行方案。

Living hotwater heating system is one of the key systems for a hotel to realize energy conservation.There is a variety of energy supplies for heating such as the recovery of waste heat and the utilization of natural heat source which are major countermeasures to reduce the energy consumption of hotwater heating.In allusion to the meteorological conditions of Hangzhou,based on the analysis of various utilization characteristics of heat sources,the configuration for applicable heat sources is summarized,and full consideration is made on the performance advantages of all kinds of heat sources under different season and temperature conditions,upon which a multi-energy complementary living hotwater heating system is proposed combined with solar energy,air heating pump and condensing boiler.The system enables a reasonable optimization of heat sources under applicable conditions so as to reduce operating energy consumption,which offers a feasible scheme for hotel improvements in living hotwater energy conservation.
