The use of natural refrigerants in large AC chillers.

Type of article: Periodical article

Summary

Large air-conditioning chillers have traditionally used HCFC-22 as the refrigerant. To address stratospheric ozone depletion, most manufacturers have adopted either R407C (an HFC blend) or HFC-134a. However, both are potent greenhouse gases, restricted under the Kyoto Protocol. In response, Earthcare has adopted hydrocarbon refrigerants that are both ozone friendly and have a low global warming potential. The technical challenge has been to achieve compliance with the safety regulations governing the use of flammable refrigerants.
