Abstract
Heat exchange experimental research results during refrigerants R404а, R407с and R410a boiling on smooth technically roughened surface in free movement conditions in large volume are presented. The dependencies between the quantitative characteristics of the boiling heat transfer process, security settings, and other factors affecting the intensity of heat transfer are established.
