What is an Insulating material? Explain. |
|
Answer» Heat always travels from high temperature to low temperature space. In all the refrigeration systems, the surroundings are always at higher temperature and heat tends to travel from the surroundings to the refrigerated space. It is necessary to isolate the refrigerated space from surroundings with a good thermal insulating material. These materials are mostly non-metallic and have a basic structure in which there are numerous cells containing air or other gases. However, some insulating materials are metallic and have heat reflecting surfaces. |
