REFRIGERANT REPORT 21

Fig. 1 Structural classification of refrigerants * Service refrigerants contain HCFC as blend component. They are therefore subject to the same legal regulations as R22 (see page 8). As a result of the continued refurbishment of older installations, the importance of these refrigerants is clearly on the decline.

The Future of Air Conditioning for Buildings - Energy

GWP refrigerants, reducing emissions during initial charging, servicing, and end-of-life disposal could help further mitigate direct emissions. Deeper reductions in emissions are possible in the long-term from lower-GWP refrigerants and improved efficiency. Without action by the international community, the expected demand for A/C in developing

CO2 Transcritical Systems Training Manual 042718

Regulation in the United States regarding refrigerants has been centered on two factors, ozone depletion potential (ODP) and global warming potential (GWP). ODP – Ozone Depletion Potential ODP is a measure of the potential of a substance to harm the ozone layer if released into the atmosphere.

GUIDELINES FOR USING R-452A AND R-448A/R-449A

Chlorine is not present in -452A and RR -448A/R-449A and consequently, these refrigerants have zero Ozone Depletion Potential (ODP) . Their Global Warming Potential is 45% and 64% respectively lower than R -404A . 3. Refrigerant Properties Glide …

Introduction to RefrigerationStandardEN378

Refrigerants should be selected with due regard to their potential influence on the global environment (ODP, GWP) as well as their possible effects on the local environment. Evaluation of the environmental performance requires a lifecycle approach. With regard to global climate change the Total Equivalent
