The document, developed by the United Nations Environment Programme (UNEP) OzonAction Branch as part of UNEP’s work programme under the CCAC, provides a number of new
commercial refrigeration case studies as well as case studies from the transport refrigeration sector, including alternatives not previously considered in the first volume published in 2014.
This publication comprises two sections. Section 1 on commercial refrigeration, specifically retail food refrigeration, provides a brief sector overview and includes six new case studies. These include a CO2/HFO blend cascade system, two different ammonia and CO2 cascade systems, a CO2 transcritical system, a propane system, and a retrofit of a centralised direct expansion refrigeration systems from an HFC to a lower GWP HFC/HFO blend refrigerant.
Section 2 provides an overview of the transport refrigeration sector and includes three case studies: two CO2 systems and a liquid nitrogen system.
