Abstract
Experimental data on the permittivity of water, ammonia and the refrigerants R134a and R152a in vapour and liquid phases have been summarized. On the basis of summarization, correlations were identified for dielectric permittivity of ammonia at saturation pressure.

Keywords: permittivity, water, ammonia, refrigerants, summarization, experimental data.
