本文讨论了风冷热泵机组在规定环境温度下以及更低环境温度条件下制热能力的相对变化和膨胀阀的对应变化，提出了在低温环境下风冷热泵机组系统设计方案，并结合实际详细介绍了风冷热泵机组除霜技术与经验数据。
This article discusses the relative changes in the heating capacity of the air-cooled heat pump unit at the specified ambient temperature and at lower ambient temperatures and the corresponding changes in the expansion valve, and proposes a system design scheme for the air-cooled heat pump unit in a low-temperature environment, combined with actual details. Defrosting technology and experience data of air-cooled heat pump units are introduced.
