Development of binary refrigeration system using CO2 refrigerant for convenience store This work analyses and quantifies the effects caused by the use of an internal heat exchanger (IHX) at the CO2 subcritical cycle in an HFC134a/CO2 cascade ... Y Yamaguchi,K Amagai - 《Mechanical Engineering ...
In CO2 refrigeration systems, the system can operate in subcritical or transcritical cycle depending on ambient temperature. When the system is operating in transcritical cycle the heat exchanger at the high-pressure side of the system is well known as gas cooler. The gas cooler rejects heat from...
Comparison of State-of-the-art CO_2 and Alternative Refrigeration Systems for Supermarkets This paper investigates the state-of-the art features of CO_2 trans-critical booster systems. The performance ofvarious modified features have been compared to the standard CO_2 booster system. Subsequently, ...
Modest research has been done in cascaded systems based on natural refrigerants thereby offering good potential for research. In this paper, a cascaded system for simultaneous heating and cooling (refrigeration and heat pump system) with a carbon dioxide based HT cycle and propane based LT cycle ...
