摘要
建立了风冷热泵冬季运行状态下基于气液分相的集中参数模型 ,在模型中不仅对蒸发器干工况和结露工况作了数学描述 ,同时还分析了结霜过程中霜层密度和厚度变化对机组性能的影响。基于这一模型 ,选择某种热泵进行了计算 。
Establish a lumped parameter model of air source heat pump based on two-phase under heating mode. In the model, dry running, dewed running, frosted running of air source heat pump are considered. An ASHP unit is chosen to compute EER and performance under frosting as the unit operates under different air temperature, air humidity and different hot water.
