Trane COL20927 Evaporator Coil

Trane COL20927 Evaporator Coil is an essential component in the many air conditioning and refrigeration circuits in HVAC systems. It works in the manner that it helps in the heat exchange mechanism while taking part several other activities. The refrigerant in its low-pressure low temperature passes through the internal passages of the coil. Heat is then exchanged from the warm air of the conditioned space to the refrigerant as the latter warms up from the external fins of the coil. This results to the evaporation of the refrigerant which in the process absorbs heat and in effect cools the air on the outer surface. The air thus cooled is then circulated back into the conditioned space and the people within it can be comfortable.
