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

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.
