A refrigeration system for supermarkets using natural refrigerant CO2 [PDF]
International Journal of Low-Carbon Technologies, 2007 This paper describes a refrigeration system using a natural refrigerant that has been developed to reduce significantly both direct and indirect greenhouse gas emissions. The new system uses both R-404A and CO 2 (R-744) as refrigerants. The new system has very low global warming potential compared with conventional HFC systems which reduces ...
