“…The result shows a decrease in the global warming potential by 52% for the R442A, and 55% for the R443A. The R453A is made up of R600 butane (0.6%) and R601a (0.6%) isopentane, which is a Class A3 natural and cheap refrigerant, see Figure 8, in its component which accounts for not more than 1.2%, and is also a Class A1 incombustible refrigerant [25].…”

This study presents the performance simulation of the R463A that has been developed to be retrofitted to replace the R404A. The R463A is primarily composed of hydrofluorocarbons/hydrocarbon/carbon dioxide (HFCs/HCs/CO2). The R463A refrigerant (GWP=1494) is a non azeotropic mixture of R32 (36%), R125 (30%), R134a (14%), R1234yf (14%), and R744 (6%). It is composed of polyol ester oil (POE), and classified as a Class A1 incombustible and non-toxic refrigerant. The R463A has a higher cooling capacity (Qe) than the R404A, as it is composed of hydrofluorocarbons (HFCs) R32 and carbon dioxide (CO2) R744, and also has a lower global warming potential (GWP) than the R404A due to the hydrofluoroolefins (HFOs) by R1234yf. The properties of the R463A and R404A that uses the REFPROP and CYCLE_D-HX software, is in accordance to the CAN/ANSI/AHRI540 standard airconditioning , heating, and refrigeration institute (AHRI). The normal boiling point of the R463A was found to be higher than the R404A by 23%, with a higher cooling capacity and a lower GWP value by 63% than the R404A. The critical pressure and temperature of the R463A was found to be higher than the R404A, i.e. it can be used in a high ambient temperature environment, and emits a higher refrigerant effect and heat reject with a lower global warming potential (GWP) than the R404A by 52%, due to its hydrofluoroolefins (HFOs) by R1234yf component. The COP of the R463A was found to be higher than the R404A by 10% under low temperature application.

“…Several strategies, such as leak detection and drop-in retrofits, can halve the environmental impact of emissions while simultaneously reducing repair costs. While HFO units are generally less energy efficient than halocarbon systems, existing HFC drop-in replacements and natural refrigerants use up to 14% less energy than currently-used halocarbons to achieve the same cooling capacity [25,26]. This reduces operating costs and can offset the higher capital costs of new halocarbon-free systems over the equipment lifetime.…”

Halocarbon refrigerant emissions are the fastest-growing source of greenhouse gas emissions around the globe. The continued use of these refrigerants poses serious environmental threats. In the absence of strong federal regulation on halocarbon use, state and local governments and institutions can commit to reducing halocarbon refrigerant emissions. Here, we outline policies that governments and users of these refrigerants can adopt to minimize their emissions. These policies include cataloging and maintaining their climate control equipment and committing to alternative refrigerants with lesser environmental impacts.

“…Commercial refrigeration [4] is one of the sectors pointed out by this regulation because of the high accidental leakage ratio, the high amount of refrigerant required and the high global warming potential (GWP) of the refrigerant most commonly used, R404A [5,6]. R404A has good thermophysical and transport properties to operate at low and medium evaporating temperatures, but its GWP is 3922 (3922 times the GWP of CO 2 based on a 100-year time horizon) [8]. Due to the recently imposed restrictions, the most relevant chemical companies are developing alternatives to R404A [8].…”

Due to the recently imposed restrictions, the most relevant chemical companies are developing alternatives to R404A [8]. These alternatives should be chosen considering different factors such as low environmental degradation, safety, and adaptation to required operating temperatures [9].…”

HIGHLIGHTS  R454C and R455A have similar properties to R404A and low global warming potential.  The experimental operation and performance of these mixtures and R404A are compared.  The average alternatives cooling capacity is comparable to that of R404A.  The R454C and R455A energy performance is higher than that of R404A.  An internal heat exchanger does not provide significant benefits to R454C and R455A.
