Automatic Control and Energy Saving Analysis of Air Source Heat Pump Hot Water System

以热泵热水技术以及自动控制技术为基础,本文提出了一种自动控制并联式空气源热泵热水系统,可以实现自动控制,确保全年不同水温条件下系统能较好运行,满足用户不同的需求。选用CYCLEPAD软件对系统进行计算分析,结果表明:系统在夏季工况下平均COP(coefficient of performance,性能系数)从5升至6.20,提升24%;在冬季工况下平均COP从3.7升至5.3,提升43%;系统在夏季工况下平均每月运行能耗从2492kW·h降至1980kW·h,降低21%;在冬季工况下平均每月运行能耗从5122 kW·h降至3642 kW·h,降低29%。

Based on heat pump hot water technology and automatic control technology,this paper proposes an automatic control parallel air source heat pump hot water system,which can realize automatic control to ensure that the system can operate well under different water temperature conditions throughout the year to meet different user requirements.need.The CYCLEPAD software was used to calculate and analyze the system.The results showed that the average COP(coefficient of performance)of the system increased from 5 to 6.20 in summer,an increase of 24%;in winter,the average COP increased from 3.7 to 5.3.,An increase of 43%;the average monthly operating energy consumption of the system decreased from 2492 kW·h to 1980 kW·h under summer conditions,a reduction of 21%;the average monthly operating energy consumption under winter conditions decreased from 5122 kW·h h is reduced to 3642 kW·h,a reduction of 29%.
