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 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： An oil separator for use in separating oil from refrigerant gas in a chiller system is provided. Its operation is based on centrifugal separation principles and does not require the use any type of filter or media pack to remove oil from refrigerant gas. The oil separator includes a non-circular (e.g., elliptical) refrigerant outlet pipe that transitions the linear flow from the inlet connection to a swirling (e.g., circular) flow within the cylindrical housing. The non-circular shape of the entrance to the refrigerant outlet pipe provides for more turbulent gas flow and a greater extraction of oil as well as minimization of pressure losses.

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： Air cooled chillers having a condenser section (300) sized to match chiller capacity and auxiliary cooling requirements satisfied by use of an independent cooling coil (314) dedicated to providing auxiliary cooling. The independent cooling coil (314) is located within the current condenser (300), but utilizes available space within the existing condenser, as well as a small portion of the airflow driven by the existing condenser fan (320). Thus, the auxiliary cooling capacity is provided with a single dedicated coil design, but which otherwise uses existing equipment and space.
