The heat pump is a device that using high level to make the heat from the low level flow to high level heat. Heat pump can extract heat from a low temperature heat source for heating. The supplying heat of heat pump is much larger than it consumes mechanical energy, heat pump technology is an energy-saving technology of low-temperature waste heat utilization. Thermal power plant uses the absorption heat, which uses steam turbine exhaust steam waste heat to increase heating network water temperature, thereby increasing heat capacity and operation economy of thermal power plant, saving energy and protecting environment.
