摘要
通过对大型风冷热泵冷热水机组经济器运行的对比实验 ,从实验角度研究了经济器运行对低温环境下运行的风冷热泵在降低压缩机排气温度 ,提高热泵机组制热能力及运行效率等方面的作用 ,对比了换热器式经济器与闪蒸式经济器的工作及调节特点 ,为采用经济器运行的大型风冷热泵冷热水机组的设计提供了实验依据 .
By the comparison be tween the experiments on large air cooled heat pump/chiller using the economizer, the capacity of economizer is investigated in reducing discharge temperature of the screw compressor, and improving heating effect and running efficiency of air cooled heat pump/chiller lower temperature. The working characteristics of different economizers is studied, which gives a basis for designing large air cooled heat pump/chiller using the economizer.
