    摘要: 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.

    摘要: An apparatus for recovering refrigerant from an air conditioning system includes an evaporator arranged to receive the refrigerant from the air conditioning system and to separate it from impurities present in it, obtaining purified refrigerant, a compressor for circulating the purified refrigerant, a condenser, and a storage container arranged to contain the condensed refrigerant. The storage container defines a storage chamber arranged to contain a liquid phase of the refrigerant and a gaseous phase including a vapor component of the refrigerant and an air component. The apparatus also includes a measuring means configured to measure operating parameters of the refrigerant present in the storage chamber, purge device arranged at a purge opening configured to purge the gaseous phase present in the storage chamber responsive to the operating parameters, and at least one first separation chamber connected to the storage container.

    摘要: The purpose of the present invention is to achieve stable operation when using a low pressure, low GWP refrigerant. In the present invention, a control device (16) is provided with an estimation unit (31), a determination unit (32), and an activation control unit (33). The estimation unit (31) estimates the amount of air entering using a degree of influence of air entering, which represents the ease with which air enters determined by the structure of the chiller, and a variable obtained by a function including pressure as a parameter. The determination unit (32) determines whether a total value for the amount of air entering is greater than or equal to a preset tolerance value. The activation control unit (33) activates a bleed device when the total value of the amount of air entering is equal to or greater than the tolerance value.

    摘要: An air drying system includes a first air dryer that receives ambient air and provides as output exceptionally dry air having a moisture concentration of approximately 16 ppm or below, a second air dryer that receives ambient air and provides as output exceptionally dry air having a moisture concentration of approximately 16 ppm or below, and a valve coupled to and selectively switching between output from the air dryers to provide exceptionally dry air, where one of the first and second air dryers is automatically regenerated while the valve switches to provide exceptionally dry air from an other one of the first and second air dryers. The air dryers may remove moisture from ambient air by cooling the ambient air to approximately −57° C. Each of the air dryers may include a heat sink section, a cooling section (possibly with cooling elements), and an air flow section.

    摘要: A system includes a condenser and an evaporator. The condenser is configured to condense a working fluid, and the evaporator is configured to evaporate the working fluid. The system also includes piping that is configured to circulate the working fluid between the condenser and the evaporator. In addition, the system includes a low point configured to collect condensed working fluid. A controller is configured to selectively enable heating of the condensed working fluid collected within the low point based on a working fluid pressure of the low point.
