A dynamic mathematical model of an air source heat pump water chiller/heater (ASHPWCH) under frosting was developed by connecting several of its component models according to principles of mass, momentum and energy conservation.

• 摘要在空气源热泵冷热水机组各部件模型的基础上，基于质量守恒定律、动量守恒定律和能量守恒定律，将这些部件模型有机地结合起来，建立了机组结霜工况下的动态数学模型。
