According to the established thermodynamic model, the off-design performance was simulated based on heating load. The thermal economic performance was compared between the two heating models before and after the reformation under the same heating load. Calculate and compare the maximum heating area of the both heating model. Results show that with the increasing of heating load, the temperature of heating network water rises up, and the heat pump COP decreases . The absorption heat pump heating supplying system is superior to the traditional extraction heating supplying system . Under the same heating load, the total heating extraction volume of heat pump hating model is significantly lower than the tradition extraction heating model, the total power generation increases by about 3% the tradition extraction heating model, and the maximum reduction of standard coal consumption rate is nearly 3%. The maximum heating area of heat pump hating model can be increased by 17.5% compared with the traditional c extraction heating model, and the maximum heating capacity of the original system is obviously increased.
