U Type Coil for R22

U Type Coil for R22

In an R22 - based refrigeration or air - conditioning system, the U - type coil serves as either an evaporator or a condenser, depending on the cycle.

Evaporator Function: When functioning as an evaporator, the R22 refrigerant enters the U - type coil in a liquid state. As it flows through the coil, it absorbs heat from the surrounding air or the fluid being cooled. The low - pressure R22 evaporates, changing from a liquid to a vapor state, thereby extracting heat and cooling the surrounding environment. This process is crucial for providing cooling in applications such as air conditioning, where the indoor air is passed over the evaporator coil to remove heat and humidity.

Condenser Function: In the condenser mode, the high - pressure, high - temperature R22 vapor enters the U - type coil. As the vapor passes through the coil, it releases heat to the surrounding air or cooling medium. The heat transfer causes the R22 to condense back into a liquid state. This condensed liquid is then returned to the expansion valve or other components in the refrigeration cycle for reuse.
