热泵季节性能系数的研究

Research on Heat Pump Seasonal Performance Factor

热泵是开发可再生能源的机械。它通过使用一份电能或机械能,获得数倍的可再生能源,是重要的节能技术和环保技术。本文重点研究热泵的季节性能系数。由于环境温度的变化或供热负荷的变化,热泵的瞬时特性可能变化,其季节性能系数的分析有重要的理论意义和实用价值。文中建议把热泵可再生能源贡献率的计算方法作为国家标准,以促进我国热泵制造产业发展,大力推广热泵节能技术。

Heat pump is a machine for renewable energy recovery. Several units of renewable energy can be obtained with the consumption of one unit of electric or mechanical energy. Therefore,heat pump is an important energy saving and environmental protection technology. This paper focuses on the heat pump seasonal performance factor. The transient characteristic of heat pump may change with the variation of ambient temperature or heating capacity. Thus,the research on seasonal performance factor has a significant theoretical and practical value. It is recommended that the renewable energy contribution rate calculation method of heat pump be set as a national standard so that heat pump manufacturing industry will benefit,and the heat pump technology will be applied.
