The Relationship between the medium giving up heat and the heat exchange surface (evaporator). This relates to the velocity of the medium passing over the evaporator. When the velocity is too slow, the film between the air and the evaporator becomes greater and becomes an insulator, which slows the heat exchanger.

An evaporator that has stamped refrigerant passages in sheet steel or aluminum.

The condition in the evaporator when the metering device is not feeding enough refrigerant to the evaporator.

A refrigerant system operated with the liquid refrigerant level very close to the outlet of the evaporator coil for improved heat exchange.

The refrigerant when all of the liquid has just changed to a vapor.

A copper or aluminum tube that has fins, usually made of aluminum, pressed onto the copper lines to extend the surface area of the tubes.

A cleaning of the compressor's bearing surfaces, which causes lack of lubrication. It is usually caused by liquid refrigerant mixing with the compressor's crankcase oil due to liquid floodback or migration.

Saturated refrigerant vapors being compressed by the compressor, which will turn into liquid refrigerant droplets when compressed.

The process of removing heat from a place where it is not wanted and transferring that heat to a place where it make little or no difference is known as__________
