热、电、冷三联供的效益分析

The Benefit Analysis of Electricity Heat and Chilled Water Congenerating System

利用现有热电联产系统发展集供热、供电和供冷为一体的能源综合利用系统。该系统将溴化锂吸收式制冷机引入到热电厂的热电联产系统中，可增加热电厂的夏季热负荷，从而使冬夏热负荷平衡，保证热电厂更经济高效地运行。通过调查和计算，将热电冷联产与热电和冷量分供系统加以比较，表明该系统不但可节能，而且具有增加电能生产和保护环境的效益。

This paper puts forward an energy comprehensive utilization system Electrictiy Heat and Chilled Water Congenerating System (EHCWCS).This system introduces H 2O LiBr Absorption Refrigerating Machine into Heat and Power Plant to increase the heat load of the plant in summer,that can balance the heat Load in summer and winter, so Heat and Power Plant can run in a high efficiency.This paper also expounded and proved the feasibility of H 2O LiBr Absorption Refrigerating Machine running as heat pump in winter.The result of analysis states that this system can not only save energy,but also increase the output of electric power of Heat and Power Plant and protect environment.
