Low global warming refrigerants for stationary air conditioning applications.

Number: pap. ID: 919

Author(s) : SPATZ M., YANA MOTTA S., ACHAICHIA N.

Summary

Due to the growing global concerns around the use of working fluids with relatively high global warming potential, new working fluids with the positive attributes of both high thermal performance and low environmental impact are currently in development. These materials maintain the high level of system efficiency we are accustomed to with fluorocarbon refrigerants but with significantly lower global warming impact than current refrigerants. They also exhibit significantly lower flammability characteristics than the much more flammable hydrocarbons. Replacements for refrigerants used in unitary and chiller systems that employ DX heat exchangers as well as flooded ones will be discussed. Chemical and physical properties as well as experimental results in representative equipment will be presented.
