In the present study, the performance of a 33 kW multiejector trans-critical CO2 cooling system is experimentally evaluated for a supermarket application with/without internal heat exchanger and evaporative cooling. In order to enhance the overall performance of the system for tropical regions, the...

CO2 cascade heat pump system has been developed to realize an ultra‐low temperature below the triple point of 0.518 MPa and − 56.6°C or less by flowing dry ice solid‐gas state of CO2 in a refrigeration system. Solid CO2 in the refrigeration system may cause to block the flow in the evaporation...
