Perspectives of chlorine free working fluids for European residential and industrial heat pumps.

Author(s) : KRUSE H.

Summary

Heat pumps will be used more, to help limit global warming. It is necessary to assess alternatives to R22 and the low-pressure gases R12 and R114, which are now in use. Carnot efficiency is related to critical temperature, which limits the choice. Chlorine-free compounds of methane are not suitable, and few of the ethane group can be used. Better performance is possible with ammonia, propane and pentane, and the limitations of these gases can be overcome. Studies are in progress with these, with the propane derivatives R227, R236 and R245 and the ethane compound R125. Some circuit design changes may be required. A.R.T.
