ABSTRACT:
An alcohol, specifically ethanol, methanol and isopropanol, is used to remove acid from a refrigeration system, a heat pump or an air conditioner. The alcohol vaporizes acid, primarily inorganic acid, in the system and, in the filter/dryer, reacts with surfaces or is adsorbed. The alcohol, the quantity of which is determined from the capacity of the filter/dryer, is introduced into the compressor oil sump for thorough mixing with the oil during compressor lubrication.
