Experiences with the refrigerant R134a as a "drop-in" replacement in a large water-water heat pump.

Author(s) : BEERMANN K., KRUSE H.

Summary

A considerable amount of large scale heat pumps working mainly with R12 but also partially with R114 have been installed in Germany in the past. This work presents first experiences with R134a as "drop-in" in a water-water heat pump with a design heat capacity of 80 kilowatts. In this plant R12 as well as a mineral oil as lubricant have been replaced by R134a and an ester oil. An energetic comparison of the plant operating with R12 and R134a is presented as well as an examination of the stability of refrigerant-oil under "drop-in" conditions.
