摘要
系统通过空气源热泵、燃气锅炉两种热源联合进行热水供应,目的是为酒店群用户提供 50℃以上的生活热水.空气源热泵为主要热源,燃气锅炉为辅助热源进行调峰,用于在酒店群用户高峰用水期或天气寒冷的情况下保证足够的供水温度.通过PLC对系统中的热源、循环水泵、电动调节阀等进行集中自适应控制,以实现该双热源联合供热系统的连续稳定运行,满足实际供热需求.结果表明,双热源联合系统比单纯使用燃气锅炉更具经济性,宜在北方寒冷地区推广应用.
Abstract
The system provides hot water through the combination of air source heat pump and gas boiler,aiming to provide hotel group users with domestic hot water above 50℃.The air source heat pump is the main heat source,and the gas boiler is the auxiliary heat source for peak regulation,which is used to ensure enough water supply temperature during the peak water consumption period of hotel group users or in cold weather.The heat source,water pump and electric reg-ulating valve in the system are controlled by PLC,so as to realize the continuous and stable operation of the dual heat source coupling heating system and meet the actual heating demand.The results show that the dual heat source coupling system is more economical than the simple use of gas boiler,and is suitable for popularization and application in cold ar-eas in the north.
