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。
This paper introduces a new application form of heat pump technology - evaporative cooling heat pump, which can overcome the heat loss of traditional air-cooled heat pump under frosting and defrosting conditions. The results show that at low ambient temperature, the average heating capacity of air-cooled heat pump unit decays more seriously. At ambient temperature of 2 ℃, the average heating capacity of air-cooled heat pump is only about 53% of that of nominal heating condition. When the ambient temperature is below 3 ℃, the average heating capacity provided by the evaporative cooling heat pump unit is higher than the average heating capacity of the air-cooled heat pump.
