    摘要： An apparatus is disclosed for the recovery, separation and recycling of refrigerant from a number of refrigerant chiller systems having individual low efficiency purgers. The apparatus has a high efficiency purger which reduces refrigerant contaminants in the non-condensable gases vented to atmosphere by 90 percent over that of the low efficiency purgers, and operates without interference with the normal purging cycles of the chillers. The apparatus further comprises conduits, valves and a pump which enables the apparatus to completely evacuate the refrigerant gas and refrigerant liquid from the chiller systems.

    摘要： A monitor for a vapor compression refrigerant system that accumulates contaminant gases 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 are disclosed which provide selective accumulation and/or analysis of contaminant gases to provide an indication of both the existence and general nature of the incipient malfunction.

    摘要： The invention is directed to a system for removing water and noncondensible gases from a refrigerant used in a refrigeration system, which refrigerant has the property of supporting more water in the liquid phase than in the vapor phase. Liquid refrigerant is maintained at a level in a chamber and is heated to drive off the refrigerant vapor. As the liquid refrigerant in the chamber vaporizes, the water content increases until the refrigerant is saturated with water. The water being less dense than the refrigerant, it will collect on the surface of the refrigerant and can be conveniently drained off. The liquid refrigerant is preferably heated by hot gas refrigerant taken from the high side of the system and after passing through a heating coil in the chamber, it is passed to a second chamber in which the vapor of the refrigerant is condensed by the liquid refrigerant flowing to the first chamber. The noncondensible gases are vented from the second chamber in conventional manner.

    摘要： A heat pump apparatus (100) includes an evaporator (10), an electrochemical compressor (11), a condenser (16), a refrigerant delivery path (18), and a non-condensable gas return path (28). The non-condensable gas return path (28) is provided separately from the refrigerant delivery path (18), and is configured to communicate a discharge-side high-pressure space of the electrochemical compressor (11) with a suction-side low-pressure space of the electrochemical compressor (11) so as to return a non-condensable gas from the high-pressure space to the low-pressure space. The non-condensable gas is, for example, hydrogen gas.
