HFCs or the old refrigerants?

Author(s) : HALOZAN H., RIEBERER R.

Summary

The alternatives for the HCFCs, which are still in use, and the HFCs are the old refrigerants, substances like ammonia (R-717), the hydrocarbons (R-290, R-1270, R-600a), water (R-718) and CO2 (R-744). The selection criteria for refrigerants have to cover efficiency, safety, and environmental acceptability. Within these criteria the environment expressed by the TEWI, i.e. refrigerant losses during lifetime and CO2 emissions caused by the production of drive energy and the drive energy, respectively, becomes a very important issue. In this context efficiency gets the highest priority, and efficiency, as can be demonstrated, is mainly the result of technology development and the correct integration of units into systems.
