Lower-GWP alternatives in stationary air conditioning: a compilation of case studies
Stationary air conditioning systems are used to provide cooling for indoor occupants for their thermal comfort at a suitable indoor air quality. Within the cooling sector the stationary air conditioning sub-sector represents the largest and most rapidly growing area of HFC use. It is associated with significant indirect emissions of CO2 due to electricity consumption, particularly in developing countries. In order to encourage industry and government policymakers to implement the phase-down of HFCs in stationary air conditioning through the adoption of lower-GWP energy efficient refrigerants, the CCAC has developed this booklet of ten case studies from around the globe, which represents various countries, climates and alternative technologies. This booklet can also serve as a reference guide for end-user and system purchasers on factors to consider when transitioning to lower-GWP air conditioning. While the case studies mainly discuss experiences relating to transitioning from HFCs to lower-GWP refrigerants, the information provided is also relevant for transitioning directly from HCFCs to such refrigerants.
