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.

    Abstract: A refrigerant recovery unit is provided that can clear oil from an oil inject path in order to prepare the unit to switch over to a different kind of oil. The refrigerant recovery unit includes an oil inject circuit that receives an oil from the oil bottle into the refrigerant system. The refrigerant recovery circuit is coupled in fluid communication with the oil inject circuit. The refrigerant recovery circuit is operable to receive and transfer a fluid drawn through the oil inject circuit. A controller is operatively connected to the refrigerant recovery circuit and to the oil inject circuit so that as the fluid is drawn through the oil inject circuit a quantity of the oil in the oil inject circuit is removed.

  • Publication number: 20070277536
    Abstract: In a closed loop refrigerant system and method, a refrigerant liquid filter is provided downstream of the condenser to receive and clean high pressure, high temperature liquid refrigerant. The invention provides means for cooling liquid refrigerant so as to render otherwise soluble contaminants insoluble before leaving the filter. The means for cooling preferably includes a refrigerant line provided in thermal contact with the liquid refrigerant in the filter. The refrigerant line contains expanded refrigerant gas or expanded liquid/gas mixture, which is at a lower temperature than the liquid refrigerant received from the condenser. Condensed liquid refrigerant is provided to the filter, which filter further includes a filter element for removing contaminants that have been rendered insoluble by the cooling of the liquid refrigerant.
