Environmental Economics and Policy Studies, 2021
If the pattern of appliance use varies between households, then we expect that appliance replacement cycle also varies between households. Although many studies identified early adopters of new energy-efficient products, few studies have examined households that have been using old energy-inefficient products and how their characteristics are ...

Sustainable development of refrigerator systems using replacement
The International Journal of Life Cycle Assessment, 2001Environmental considerations have led to the phase out of chlorofluorocarbon (CFC) refrigerants from the domestic refrigeration industry. One intriguing aspect is that the chlorine in CFCs is a good lubricating agent and any deterioration of system performance may adversely influence other environmental considerations.

Criteria for Drop-in Replacement of Existing Refrigerant with an Alternative Refrigerant
2019In the present work, criteria for substituting working refrigerant with alternative refrigerant is given through R134a being replaced with ternary mixtures of R134a/hydrocarbons. Thermodynamic properties were compared theoretically using REFPROP software for five refrigerant mixtures.

New Refrigerant Options For R404A Replacement In Truck Refrigeration Systems
2015R404A is largely used in refrigerated transportation systems. Given the relatively high refrigerant leakage rates of transportation systems and the relatively high 100-year GWP (3943) of R404A, it is increasingly under scrutiny. Furthermore, containment measures are included in the recent European Union F-Gas regulation 517/2014.

Replacing Ozone-Depleting Substances Used as Refrigerant Working Fluids
Chemical and Petroleum Engineering, 2001oping economies following closely: transport, communications, medicine, and food have all evolved beyond recognition within a very few generations. In support of these changes, whole new industries have developed and evolved. One of these is the refrigeration industry.

Applied Energy, 2011
Abstract This paper presents the results of an experimental analysis comparing the performance of a vapour compression refrigerating unit operating with R22, and its performance in comparison to a new HFC fluid, substituting the former according to Regulation No 2037/2000.

Chemical Engineering Journal, 2011
Abstract Replacement of halogenated refrigerants with a suitable refrigeration system in order to prevent ozone layer depletion and minimize global warming has been a matter of research and worldwide attention for some decades. This paper presents the design and description of a single chambered experimental model for cold generation based on ...
