摘要:
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.
