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.
