    Abstract: A purge system for removing non-condensables from a chiller system includes a purge chamber, a plurality of carbon beds fluidly connected to the purge chamber into which a flow of refrigerant and non-condensables is selectably directed from the purge chamber to remove the non-condensables therefrom. A vent line is fluidly connected to the plurality of carbon beds to dispose of the collected non-condensables, and a heater is operably connected to the plurality of carbon beds to selectably heat one or more of the carbon beds of the plurality of carbon beds to release refrigerant therefrom and direct the released refrigerant to the purge chamber.

    Abstract: A system is provided including a vapor compression cycle. The vapor compression cycle includes an operably coupled compressor, condenser, first expansion device, and evaporator through which a refrigerant circulates. A thermal energy storage unit includes a heat exchanger arranged within a phase change material. The heat exchanger is fluidly coupled to the vapor compression cycle with a plurality of conduits and valves such that refrigerant flows through the heat exchanger in a heat transfer relationship with the phase change material. When the system is in a first mode, the heat exchanger is configured to function similar to the evaporator and the phase change material is configured to store thermal energy. When the system is in a second mode, the heat exchanger is configured to function similar to the condenser and the phase change material is configured to release thermal energy.

    Abstract: A method and an analyzer for detecting impurities in refrigerant (e.g. methyl chloride (R40) or Chlorodifiuoromethane (R22)), wherein the refrigerant analyzer (12) includes a first sensing device (16), preferably a non-dispersive infrared sensor (NDIR), in flow communication with a second sensing device (18), preferably an electrochemical sensor. The first sensing device is configured to determine a first characteristic of a refrigerant (e.g. absorbance in the IR range), and the second sensing device is configured to detect a second characteristic of the refrigerant (e.g. concentration in ppmv). Preferably, the refrigerant analyzer is a part of a system for detecting impurities (10) and further preferably it comprises flow regulators (20), a scrubber (24) and a processor (22). The scrubber is preferably in flow communication with the first sensing device and it preferably comprises a packing material comprising alumina (Al2O3, aluminum oxide).

    Abstract: A heat transfer system is disclosed that includes a heat exchanger comprising an inlet, an outlet, and a flow path through the heat exchanger between the inlet and the outlet. The system also includes a fluid circulation loop external to the heat exchanger connecting the outlet to the inlet. A phase change composition is disposed in the system flowing through the fluid circulation loop and the flow path through the heat exchanger. This the phase change composition includes a first PCM that is a plant or animal or paraffinic oil having a first melting point and a second PCM that is a plant or animal or paraffinic oil having a second melting point lower than the first melting point.
