CO_2热泵-太阳能热水系统在温和地区的节能分析

Energy Efficiency of a CO_2 Heat Pump-Solar Water Heating System in Mild Area

以温和地区昆明某酒店中央热水系统改造为例,对比分析了太阳能-CO_2热泵系统和太阳能-电加热系统的初步投资和后期的运行成本,结果表明太阳能-CO_2热泵系统具有重大的经济性和环保性优势,是具有节能、减排的先进技术,在我国太阳能资源丰富的地区可以推广使用。

Taking the central hot water system reconstruction of a hotel in Kunming as an example, the initial investment and the later operation cost of the solar-CO2 heat pump system and the solar-electric heating system are compared and analyzed. The results show that the solar-CO2 heat pump system is of great economic importance and environmentally friendly, which is an advanced technology with energy saving and emission reduction, and also can be promoted and used in areas with abundant solar energy resources in China.
