Vapor compression refrigerant system monitor and gas removal apparatus

摘要

A monitor for a vapor compression refrigerant system using halocarbon refrigerants that accumulates contaminant gases present or generated in an operating system and provides a readout indicative of the presence of significant amounts of contaminant gases which readout serves to provide an indication of an incipient malfunction of the refrigerant system. Embodiments of the monitor are disclosed which provide continuous and automatice purging of the contaminant gases from the system using perm- selective membranes with or without provision for providing indicia of the presence or build-up of contaminant gases in the monitor.
