Abstract: 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.

Abstract: The use of sealants based on organosilanes for refrigeration and air conditioning systems is made possible by control of the rate of introduction and viscosity of the sealant mixture within certain ranges. An appropriate choice of organosilane sealant is made to allow effective sealing of small pinhole size leaks in the air conditioning or refrigeration system. The organosilane is then combined with a miscible lubricant at particular ratios to provide the proper mixture viscosity for injection into the refrigerant system to prevent bearing seizure. Specific orifice sizes are selected for an apparatus to ensure that the composition is injected at the flow rates required to prevent liquid slugging and subsequent compressor shutdown or failure. In addition, effective introduction of the mixture requires certain procedures be performed. Injection procedures are also described that prevent temporary or catastrophic equipment shutdown.

Abstract: A vacuum gauge has a scale having a safe zone indicia, a working zone indicia, an indicator to indicate a particular location on the scale, and a pressure sensing mechanism and housing having a pressure sensing port accessible for fluid connection to the refrigeration system to receive fluid for sensing. The indicia are distinctly coded for user differentiation. The scale may include a leak indicating zone indicia and a non-working zone indicia The safe zone indicia may represent 0 to 500 microns, the working zone indicia 500 to 2000 microns, the leak indicating zone indicia 2000 to 25,400 microns, and the non-working zone indicia 25,400 to 30,000 microns. Service tool combination includes body assembly, shaft assembly and gauge in direct sealed connection with a fitting for releasable sealed fluid connection. There are methods using the combination. Tool has gripper with cavity to receive valve core pin. Gripper has base to prevent pin from pulling gripper from tool.
