HEAT FLOW THROUGH A TYPICAL WALL IN AKURE By Adeyinka
... The R-Value are also used to describe steady-state heat flow, but in a slightly different way. The R-Value is the thermal resistance to heat flow. A larger R-Value has greater thermal resistance, or more insulating ability, than a smaller R-Value. The big advantage of R-Values is that they can be ad ...

Heat exchanger
A heat exchanger is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air.
