This study presents a single CO2 vapour-compression system for independent cooling and dehumidification of indoor air conditioning systems. A CO2 gas cooler outlet split (GOS) ejector system is introduced to generate two levels of evaporating temperature, and therefore indoor air temperature and hum...

Waste heat is an abundant resource that if recovered with a heat pump would increase energy efficiency in industrial processes. This will provide improvements in heat utilization and reduce the environmental impact of greenhouse gas emissions from the combustion of fossil fuel. A hydrocarbon high te...

Evolution in modifications for CO2 system configuration came across from the last two decades has proven to hold the potential in order to improve the overall performance of the CO2 cooling system for various applications. However, performance of the CO2 system at high ambient context is not promisi...
