    摘要： A chiller system includes a refrigerant loop, the refrigerant loop further including a compressor, an air-cooled condenser arrangement and an evaporator arrangement connected in a first closed refrigerant loop. A motor is connected to the compressor to drive the compressor, a drive is connected to the motor to power the motor and a power/control panel controls the refrigerant loop. The power/control panel and the condenser arrangement are connected in a second closed coolant loop. The second closed coolant loop provides cooling to the enclosure and/or components within the enclosure disposed on a chill plate. Condensation is substantially prevented from forming inside the enclosure, despite the enclosure lacking a humidity control device.

    摘要： A system and method are provided for variable speed operation of a screw compressor to obtain increased capacity and efficiency. The screw compressor is connected to an induction motor driven by a variable speed drive, wherein the screw compressor has a variable output capacity that is dependent on the output speed of the motor. To obtain increased capacity and efficiency, the screw compressor is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor, which speed is greater than the rated speed, is related to the maximum operating speed of the motor when operated at a voltage and frequency provided by the variable speed drive that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.

    摘要： A liquid refrigerant drainage mechanism is described for use in a flooded evaporator to mitigate liquid carryover. The drainage mechanism can trap liquid refrigerant droplets, create a liquid column to overcome a pressure difference across the mechanism and drain liquid back to the pool in the evaporator. The drainage mechanism is disposed in a suction baffle, and has a mesh pad and a tapered pipe secured to the bottom of the baffle. The pipe has a drainage aperture at one end to allow the accumulated liquid refrigerant to return to the refrigerant pool below. The mesh pad helps to separate liquid droplets that coalesce and fall into the tapered pipe. By using this liquid drainage mechanism in conjunction with a suction baffle, liquid carryover can be reduced and chiller performance improved.

    摘要： A method for determining the composition of a ternary refrigerant in a refrigeration system. The method calculates the composition of the ternary refrigerant under the assumption that the expansion cycle is isenthalpic and that the ratio of two components in the ternary mixture remain fixed in relation to one another before and after the expansion. These assumptions permit the calculation of composition of a ternary mixture with relatively few inputs.

    摘要： 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. The filtered liquid refrigerant, from which otherwise soluble contaminants and insoluble contaminants have been removed, can then be supplied to downstream components such as expansion devices, evaporators, and compressors.

    摘要： A plate heat exchanger for accommodating a circulating refrigerant and heat transfer fluid. The plate heat exchanger includes a plurality of heat transfer plates and at least one electrode plate. The plurality of heat transfer plates are mounted in parallel relationship to each other defining alternating flow spaces for a refrigerant and a heat transfer fluid. The electrode plate is located in each refrigerant flow space and is spaced from the adjacent heat transfer plates. The electrode plate includes outer electrode surfaces on each side thereof to produce an electric field. The effect of the electric field is an increase in the heat transfer rate between the refrigerant and heat transfer fluid. The invention also includes a method of exchanging heat between a heat transfer fluid and a refrigerant in a plate heat exchanger.
