The evaporator is an important component among the four major components of refrigeration. The low-temperature condensed liquid exchanges heat with the outside air through the evaporator, vaporizes and absorbs heat, achieving the effect of refrigeration. The condenser is another important component of the refrigeration system, which can convert gases or vapors into liquids and quickly transfer heat from the pipes to the air, thus achieving the purpose of heat exchange. Condensers are usually divided into two types: evaporative condensers and air-cooled condensers.
