耦合燃气加热功能的集中制冷加热系统应用研究
Application of centralized cooling and heating system coupled with gas heating
摘要：
以夏热冬冷地区某燃气-蒸汽联合循环热电厂的集中制冷加热系统为例，简要介绍了制冷加热系统的不同运行工况，在忽略系统自身能耗和各项损失的前提下，仅考虑水源热泵机组电耗，对联合应用循环冷却水的集中制冷加热系统进行了节能、节水效果分析。结果表明：该多功能系统加热天然气比其他常规加热方式年节约天然气数十万甚至上百万m3；循环冷却水中的废热利用还间接获得每年数千m3的节水效果。
Abstract：
Taking a centralized cooling and heating system of a gas-steam combined cycle thermal power plant in hot summer and cold winter zone as an example, briefly presents the different operating conditions of the centralized cooling and heating system, and analyses the energy saving and water saving effects of the centralized cooling and heating system combined with circulating cooling water on the premise of ignoring the system energy consumption and various losses and only considering the power consumption of the water-source heat pump. The results show that the multi-function system saves hundreds of thousands or even millions of cubic meters of natural gas per year compared with other conventional heating methods, and the utilization of waste heat in circulating cooling water indirectly achieves a thousands of cubic meters of water saving effect per year.
