What is direct expansion coil?

- Mar 12, 2020-

The direct expansion coil is a very important part of the four major pieces of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, and the vaporization absorbs heat to achieve the cooling effect.

The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber supplies the liquid with the heat needed for evaporation, which promotes the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.
