Taking a thermal power plant as the research object,according to the waste heat resources and cooling and heating load requirements of the plant,a steam-type absorption heat pump system based on waste heat recovery was proposed.The system recovers the waste heat from the circulating water of the desulfurization tower in winter for the heating and heating boilers in the plant area,and uses the boiler desalinated water at 20℃ as a coolant in the summer to recover the heat gained from the building.Then,the energy consumption model of the original air-conditioning system and the waste heat recovery system was constructed by using EnergyPlus software,and the differences between the two in terms of energy consumption,operating cost and environmental protection benefits were compared and analyzed by taking a simulation cycle as an example.The results show that the system can recover 103.05 tce of heat,save 3.79 tons of standard coal,and reduce CO2 emissions by 18.53 tons per year,which has significant energy saving and environmental protection effects.
