Power System Driven By A Low-Temperature Heat Source

Abstract

A power system driven by a low-temperature heat source includes a power cycling unit and a heat pump unit. The power cycling unit includes a turbine, a condenser, a pump, a first heat exchanger, and a second heat exchanger. The turbine, the condenser, the pump, the first heat exchanger, and the second heat exchanger are connected in sequence. The heat pump unit includes a condenser and an evaporator. The condenser of the heat pump unit is connected to the second heat exchanger. The evaporator is connected to the condenser of the heat pump unit. The evaporator absorbs heat of a working fluid in a waste heat pipe.
