Assessment of propane as a refrigerant in residential air-conditioning and heat pump applications.

Author(s) : KELLER F. J., LIANG H., FARZAD M.

Summary

The performance, cost, and environmental impact of propane systems were evaluated in two typical residential air-conditioning and heat pump applications: ducted air-to-air split systems and window room air conditioners. Flammability mitigation strategies were analyzed and the corresponding safety modifications were used for each product type. R22 systems were used for the baseline designs. R410A and propane designs were compared to the baseline systems. The total equivalent warming impacts (TEWI) reduction per unit of investment was the primary comparison criterion for each equipment category. Results are given. There are other risks and concerns not discussed in the paper that must be addressed before propane could be considered a safe refrigerant for the applications investigated. Further research will be necessary to provide sufficient evidence that propane can be safely applied in the products discussed in the paper.
