Abstract
The work is devoted to the study of the boiling process of multicomponent working fluids (MWF) used in refrigeration and cryogenic engineering. The description of the method of determination of heat transfer coefficient during boiling of zeotropic mixtures in horizontal heated channel is given as well as the design of the experimental stand allowing to make such measurements. This stand is designed on the basis of a refrigeration unit operating on the JouleThomson throttle cycle and allows to measure the heat transfer coefficient with an error not exceeding 15 %. Knowing of the heat transfer coefficient will be very useful in the design of heat exchangers for refrigeration machines operating on a mixed refrigerant.
