An evaluation of HFC-245ca for use in low-pressure chillers.

Type of article: Article

Summary

The article summarizes the findings of an assessment of HFC-245ca as a possible alternative to CFC-11 and HCFC-123 in low-pressure chillers. It was concluded that chillers designed for HFC-245ca can provide efficiencies comparable to those of HCFC-123 and CFC-11 chillers. However, hurdles applying to HFC-245ca in centrifugal chillers include flammability, toxicity, unknown heat-transfer characteristics, uncertain thermodynamic properties, high refrigerant cost and high construction costs of HFC-245ca production plants. Moreover, it is unlikely that a large market will develop for converting existing chillers from CFC-11 or HCFC-123 to HFC-245ca.
