Composition and methods for injection of sealants into iivac and refrigeration systems

摘要

An apparatus (12) and method for injecting sealant mixtures based on organosilanes into a hermetically sealed refrigeration and air conditioning systems are described. The mixtures are injected at controlled flow rates and viscosity to prevent bearing seizure. The apparatus (12) comprises metering means (20, 22) such as orifices of different sizes regulating the flow of mixture from a sealed canister (15) into an injection port (17) installed on a low (10) or high (11) side of a compressor (5).
