Abstract
A method and apparatus for sampling the purity of refrigerant flowing through a refrigeration system is provided. A refrigerant sampling chamber is operably connected and parralel fluid flow communication with a compressor of the refrigeration system. Operation of the compressor to establish the flow of refrigerant through the system results in withdrawal of a quantity of refrigerant from the high pressure side of the system. The withdrawn refrigerant passes through the refrigerant sampling chamber and a refrigerant quality testing tube contained therein. Following passage through the test chamber the withdrawn refrigerant is returned to the low pressure side of the refrigeration system.
