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.

We claim: 1. A method for injecting sealant into a charged air conditioning or refrigeration system having a compressor, a high pressure side (“high side”), and a low pressure side (“low-side”), the method comprising:injecting the sealant into the low pressure side of the system during operation of the charged air conditioning or refrigeration system in a quantity to provide sufficient lubrication to maintain proper operation of the compressor when the sealant is fully distributed in the system, whileinjecting the sealant at up to a maximum controlled rate controlled by a second orifice that is separate from and smaller than a first orifice created by a piercing valve, so as to maintain proper operation of the compressor before the sealant is fully distributed in the system.
