燃气机驱动的供热空调系统容量调节的研究

Investigation of capacity control of gas engine drived heat pump

在采用冷负荷系数法计算我国典型气象地区负荷分布的基础上 ,对燃气机驱动的供热空调系统在不同压缩机转速下的变工况特性、变速容量调节性及其节能机理进行分析 。

The seasonal characteristic of heating and cooling load of buildings has been analyzed.The behaviors of the capacity control by varying the speed of gas engine and compressor of gas driven heat pump have been investigated.The research results show that we can not only remove or reduce the on-off loss of ordinary heat pumps but can also improve its Energy Efficiency Ratio in part-load operating conditions and reduce the fluctuation of room temperature.
