dc.description.abstractChemical stable chlorinated hydrocarbons destroy the protecting ozone layer in the upper parts of the atmosphere - this has been found about 15 years ago, and since that time it became more and more clear how serious the problem is. Traditional refrigerants, e.g. R11 (CCl 3F) and R12 (CCl 2F 2), have to be replaced in course of the next few years by substances which contain less or even no chlorine, for example by R123 (C2HCl 2F 3) and R134a (C 2H2 F4) respectively. Application of new substances as working fluids in refrigeration cycles and as blowing agents in foaming of polyurethane (PUR) requires detailed information about toxicological, chemical and thermophysical properties, like latent heat of vaporization, density, boiling curve, viscosity - and thermal conductivity.en
