COMPOSITIONS AND METHODS FOR INJECTION OF SEALANTS AND/OR DRYING AGENTS INTO AIR CONDITIONING AND REFRIGERATION SYSTEMS

摘要

A method for maintaining a charged and pressurized air conditioning or refrigeration system, such method including introducing into the system fluid of the air conditioning or refrigeration system a hydrolytic drying agent, and distributing the hydrolytic drying agent throughout the system fluid; methods of maintaining a charged and pressurized air conditioning or refrigeration system including introducing a hydrolytic drying agent and a sealing agent; devices for maintaining a charged and pressurized air conditioning or refrigeration system which include a sealed vessel containing a hydrolytic drying agent and a sealant; kits for the same.
