Abstract
A transcritical heating system for providing heat to a heating medium includes a controller and a heat pump. The heat pump includes a working fluid characterized by a critical pressure and a critical temperature, a compressor configured to compress the working fluid above its critical pressure and temperature, a first heat exchanger (HX) in fluid communication with the compressor and with a closed medium flow circuit, a high-pressure valve, and an evaporator for cooling the working fluid. The controller is in communication with the heat pump in order to regulate a temperature of the heating medium in the closed medium flow circuit. The system may also include a second heat exchanger in fluid communication with the first HX and with an open medium flow circuit.
