A Heat Pump for Simultaneous Refrigeration and Water Heating

A novel heat pump has recently been proposed which provides both refrigeration and water heating using a transcritical CO2 cycle. Applications in the food processing industry have been identified where the transcritical CO2 heat pump could provide large energy cost savings with reduced environmental impact compared with conventional systems. In this paper, the energy efficiency of the heat pump is quantified and the potential economic and environmental benefits are discussed.
