摘要
针对风冷热泵机组在制热工况下容易结霜的特性 ,本文论述了利用压缩机排出的热气来除霜的方法 ,阐述了热气除霜循环的原理和过程 ,并提出了除霜总负荷及除霜时间的计算方法。
Heat-pump units tend to frost in heating cycle. Therefore this paper presents a new defrosting methods using hot gas. Meanwhile the principle and process are also illustrated together with the calculation methods for total defrosting heat load and defrosting time. The total heat load includes the preheating load and melting load.
