摘　　要：空气源热泵机组是以空气为热源,它可以在炎热季节实现制冷,寒冷季节实现制热,从而省去了冷却水系统以及锅炉等设备。但其低压和结霜的问题一直是制约其应用的一个重要因素。对空气源热泵机组的工作原理进行了讨论,分析了其形成低压和结霜的原因,对热气旁通技术进行了讨论,阐述了其在解决空气源热泵机组两大主要问题方面的应用,并通过实验证明其有效性。Air source heat pump is the air as the heat source,it can be in the hot season of refrigeration,heating to achieve the cold season,thus eliminating the need for cooling water systems and boilers and other equipment.But the issue has been low and frost is a major restricting factor in their application.Air source heat pump works were discussed,analyzed the reasons for the formation of low pressure and frost on the hot gas bypass techniques are discussed,described its air source heat pump units in solving two major problems in the application,and Experiments prove its effectiveness.
