Abstract

A heat supplying system of water source heat pump utilizing condensed steam residual heat is prepared as adding heat net heater, steam leading-in pipe, condensed water leading-out pipe, heat net pump, heat net water supply pipeline, heat net returning water pipeline and heat pump based on original cooling system of power plant, utilizing added system to lead all or partial exhausted steam from steam turbine of power plant to heat net heater then to heat pump set at user location for extracting residual heat out from heat net circulation water and for heating it up to certain temperature as well as for supplying heat to user.

Description

technical field [0001] The invention relates to a system and method for heat supply using the condensed waste heat of a power plant (including a thermal power plant) as a low-level heat source of a heat pump, and belongs to the technical field of thermal engineering. Background technique [0002] 1. Heat pump technology [0003] In recent years, with the maturity and development of heat pump technology, various heat pump heating technologies have been widely promoted and applied in our country. A heat pump is a device that uses high-level energy to make heat flow from a low-level heat source to a high-level heat source. The heat supplied by the heat pump (that is, the heat obtained by the high-level heat source) is the sum of the consumed high-level energy and the heat absorbed from the low-level heat source. Therefore, heat pumps are used The device can make full use of low-grade energy and save high-grade energy. [0004] At present, the low-level heat sources commonly u...
