摘要
针对单一制冷剂热泵热水器运行工况和除霜等方面的不足,给出了一种双制冷剂热泵热水器,具有不同季节运行参数波动小、可提供低温和中温两种热水、除霜耗能少等特点。
In order to overcome deficiency of heat pump water heaters with single refrigerant in working states and defrosting,a dual-refrigerant heat pump water heater with little fluctuation of operation parameters in different seasons,supply of low-temperature and medium-temperature water respectively,and less energy consumption in deforsting was presented.
