Abstrakt
Transcritical heat pumps using CO2 as a working fluid can be more environmentally friendly than conventional heat pumps. To increase the efficiency of the system, a two-phase ejector with an adjustable needle is considered in this work. Considering the type of operation, heat transfer using plate heat exchangers is considered in the paper. The paper deals with the design of an experimental supercritical heat pump concept with CO2 refrigerant for use in residential wastewater heat recovery applications.
