空调冷凝热回收热水供应系统方案研究

Scheme development of air-conditioning condenser heat recovery hot water supply system

空调冷凝热与热水供应负荷之间的不平衡性问题是制约空调冷凝热回收热水供应系统(HeatRecov eryHotWaterSupplySystem,HRHWS)发展的主要因素.通过对香港地区中高档旅馆空调冷凝热的动态模拟以及对热水供应变化规律的研究,归纳出系统四种典型运行工况,直观展示出两者在时间和品位上的不平衡性.引入热泵、蓄热装置(包括蓄热水罐和消防水池)等技术措施,提出两种较为可行的HRHWS系统方案,从方案创新的角度解决以上问题.

The imbalance between air-conditioning condenser heat load and hot water supply load is the main factor that restricts the development of air-conditioning condenser heat recovery hot water supply system (HRHWS). By simulating the condenser heat in Hong Kong luxury hotel and packing up the variation rule of hot water supply load, four typical operation modes are concluded which intuitionally show the imbalance from the aspects of time and taste. Water heat pump, heat storage device and other technical managements are introduced in the current air-conditioning and hot water supply system. Two HRHWS system schemes are given. The improved system can solve the above problems in an effective way.
