寒冷地区浴池热水供应方式运行经济性比较分析

Comparative Analysis on Cost for Various Hot Water Supply Methods of Public Baths in Cold Region

太阳能-空气源热泵热水系统作为可再生能源已得到广泛应用,但在我国北方寒冷地区运用较少。再加上空气源热泵自身存在低温环境运行效率过低甚至损坏机组的现象,需要对不同辅助热源辅助太阳能热水系统进行经济技术比较分析,以得到最佳的运行方案。通过对不同辅助热源辅助太阳能热水系统进行技术分析与计算,建立数学模型,模拟计算加热100 t水的全年运行情况,计算、分析不同辅助热源太阳能热水系统运行方案在长春地区的年运行总成本,结果表明:太阳能-空气源热泵-水源热泵热水系统在我国北方寒冷地区使用有很可观的发展空间。

Solar energy-air source heat pump hot water system has been widely used as a renewable energy, but less in the cold area of northern Chin~ In addition, the running efficiency of the air source heat pump is worse in low temperature condition even damage to the unit, so solar hot water systems with difference auxiliary heat sources need to be compared and analyzed on cost and technology for selecting the optimal running scheme. Based on the analysis and calculation of solar hot water systems assisted with different auxiliary heat source, the mathematical model is established to simTtlate and calculate the annual operation of 100 tons of hot water. The running cost of various schemes in Changchun is expounded, the results show that solar energy-air source heat pump-water source heat pump hot water system has a very considerable enhancing space in cold regions of northern China.
