Influence of the color of the refrigeration body on its thermal parameters

Abstract

The article discusses the issue of the impact of the color of refrigeration bodies on the thermal parameters of insulation. The tests of the density of heat flux flowing through metal claddings were carried out, and then their heat transfer coefficient was calculated on their basis. In the further part of the article, the influence of the body colour on the thermal conductivity of a three-layer wall consisting of an insulating core (expanded polystyrene) and two external claddings of different colour was analyzed. On the basis of the obtained results, it can be stated that the colour of the body affects the value of heat that passes through it.
