摘　　要：本文介绍了一种新的热泵技术应用形式——蒸发冷却式热泵,可以克服传统风冷热泵在结霜、融霜情况下热量的损失。试验结果表明:在低环境温度下,风冷热泵机组的平均制热量衰减较为严重;在环境温度?2℃时,风冷热泵的平均制热量只有名义制热工况热量的约53%;在环境温度低于3℃时,蒸发冷却式热泵机组提供的平均制热量高于风冷热泵的平均制热量。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.
