Diagnosis and Treatment of Ice and Frost Formation in Cooling Coils in Air Conditioners or Heat Pumps, Refrigerant Line Frost Caused and Remedy. Evaporator Coil Icing: Ice and frost formation in air conditioning system air handling units, fan units, plumbing, or other air conditioning system components problems. Freezing or frosting/air conditioning coil block air flow, resulting in loss of cooling. Simple basic diagnostics are also in the cooling coil for freezing or leaking.
In the form of cooling coils, where there is no more frost on the coil, we know that there is a point where there is no more liquid refrigerant on the coil. That is, all of the introduced liquid refrigerant as it travels through the cooling coil has boiled to gas at this point. Now, because of all the vapor, the refrigerant starts to absorb sensible heat and its temperature will increase. There is a lot of pressure increase on the coil at this point, but it's all insignificant.
In the refrigeration class demonstration, we learned that one can, given no other data, determine the proper refrigerant charge by adjusting the refrigerant flow to the coil or, better yet, the proper adjustment of an adjustable refrigerant metering device so that just The frost line stops before the end of the coil.
Normal cooling of built-in air over cooling coils: In normal operation an air conditioning system cools air by moving it through an "evaporator coil" that cools in the refrigerant, or a "cooling coil" in the air handler.
The Dehumidifying Cooling Coil: Cooling the air through the coil also removes moisture from the air - a key factor in making indoor air comfortable in hot weather.
Usually this is the moisture removed from the surface of the air condensing cooling coil in the architectural form, ie the surface flows down into a collection pan, where it is drained.
