重庆某项目蒸发冷却式热泵机组节能运行研究

Research on Energy-Saving Operation of Evaporative Cooling Heat Pump Units in a Project in Chongqing

分析了某项目全年空调运行的负荷特性,干湿球温度特性对SCOP的影响,从而制订出蒸发冷却式热泵机组的高效运行策略。与传统风冷热泵比,制冷季运行的节能效益优势以及在制热季低温环境下,蒸发冷却式热泵机组制热量高于风冷热泵制热量,可降低设备容量的特点。

This article provides a detailed analysis of the load characteristics during the annual air conditioning operation of a certain project,as well as the impact of dry and wet bulb tempera⁃ture characteristics on SCOP in different months.Based on this,an efficient operating strategy for evaporative cooling heat pump units under different months and load rates is formulated to guide practical applications.Compared with traditional air-cooled heat pumps,the energy-saving ben⁃efits of operating during the refrigeration season and the fact that in the low-temperature environ⁃ment during the heating season,the heat generated by evaporative cooling heat pump units is higher than that of air-cooled heat pumps,which can reduce equipment capacity.
