HCFC-22, widely used in variety of refrigerating/heating equipment, has been scheduled to
be phased out by Montreal Protocol. This decision will result in significant reduction of ozone …

The adequate and efficient performance of HVAC systems are signs of luxury and human
comfort, and the improvement of their performance has been the target of continuous …

International agreements will restrict in the near future the use of high-GWP refrigerants in
Europe. These restrictions will favour the implantation of refrigeration systems with low-GWP …

Steady state performance of residential air conditioning systems using R22 and alternatives
R290, R407C, R410A, at high ambient temperatures, have been investigated …

This work evaluates R-454C, R-459B, R-457A and R-455A as R-404A low-GWP substitutes
in a stand-alone commercial refrigeration system for fresh product under ISO 23953-2 …

This work analyses and quantifies the effects caused by the use of an internal heat
exchanger (IHX) at the CO 2 subcritical cycle in an HFC134a/CO 2 cascade refrigeration …

Owing to environmental problems arising from the use of refrigerants, first the ozone
depletion and later the global warming, various refrigerants have been banned and their …

In this study, thermal and exergy performance analyses for an air conditioner split unit
(ACSU) operating with R-161 were analysed under different Iraq climatic conditions to …

It is well-known from previous investigations that energy parameters of the systems, which
operate using directly alternative refrigerants, have poorer energy parameters compared …

The R22 refrigerant widely used in refrigerating and air conditioning devices is invariably
released to the atmosphere due to reasons such as breakdown and/or translocation. As the …
