| description | The use of heat pump to recover the condensing heat of the unit can realize the cascade utilization of energy, improve the utilization efficiency of energy, not only can effectively increase the heating capacity of the unit, but also can improve the use efficiency of heating extraction steam, so as to improve the economy of the thermal power plant. Heat pumps suitable for use in power plants can be divided into absorption heat pumps and compression heat pumps. Which type of heat pump is more economical needs specific judgment for the specific application environment. In this paper, a specific example is used to compare the economy of the two heat pump systems. The calculation results show that the economy of the compressed heat pump is better than that of the absorption heat pump only when the COP of the compressed heat pump is greater than the critical value, and the waste heat recovery ability and water saving performance of the compressed heat pump are better. |
