基于热电厂与热水管网的集中供冷模式

Centralized cooling mode based on cogeneration power plant and hot water pipe network

介绍了一种利用热电联产集中供热系统实现夏季供冷的模式,其特点是在热电厂设置汽轮机抽汽驱动的吸收式热泵,回收汽轮机乏汽或循环冷却水余热,梯级加热热网水;在用户热力站设置热水型吸收式制冷机和溶液调湿型空气处理机,承担用户夏季空调冷负荷。该方式夏季利用热电厂的高温热水驱动制冷机,可提高集中供热系统的设备利用率,降低夏季城市的供电负荷。

Describes a new way for summer cooling based on the central heating system of combined heat and power generation.The characteristic is that the absorption heat pump driven by steam extracted from steam turbine is set up in cogeneration power plant.The absorption heat pump is used for recovering waste heat in exhausted steam of steam turbine or circulating cooling water.Network water is heated by cascade utilization.At the user＇ s heating station,absorption chillers driven by hot water and solution-humidifying air handling units are set up to undertake building cooling load in summer.By this way,high temperature hot water from cogeneration power plant is used to drive refrigeration units in summer,which can improve the equipment utilization rate of the central heating system and reduce the power load of cities in summer.
