摘要
针对空气源热泵冷热水机组冬季制热运行时换热器结霜与除霜的问题,提出了一种能量分析法。从能量转换和能量传递的角度出发,分析一种常见的除霜方法——逆循环除霜。通过对除霜过程的讨论,找出了相应的减少除霜损失的方法。
In this paper, a view about energy analysis is stated to resolve the problem of frosting and defrosting onheat exchangers, when air source heat pump operates in winter. And a method named contra-cycle defrosting is ana-lyzed according to the energy transform and transfer. After discussing the defrosting process, corresponding ways todecrease defrosting loss are put forward.
