摘要
Abstract
A new application of heat pump technology, evaporative cooling heat pump, was proposed in order to overcome the drawback of the heat losses of conventional air cooled heat pump units during frosting and defrosting. The experimental results show that the average heating capacities of air cooled heat pump unit decrease seriously at low ambient temperatures. At –2 oC ambient temperature, the average heating capacity is 53%of the nominal heating capacity. At ambient temperatures lower than 3 oC, the average heating capacity of the evaporative cooling heat pump unit is higher than that of the air cooled heat pump unit.关键词
