摘要： A system and method are provided for variable speed operation of a screw compressor (108) to obtain increased capacity and efficiency. The screw compressor (108) is connected to an induction motor (106) driven by a variable speed drive (104), wherein the screw compressor (108) has a variable output capacity that is dependent on the output speed of the motor (106). To obtain increased capacity and efficiency, the screw compressor (108) 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 (108), which speed is greater than the rated speed, is related to the maximum operating speed of the motor (106) when operated at a voltage and frequency provided by the variable speed drive (104) that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.

摘要： A capacity control algorithm for a multiple compressor liquid chiller system 300 is provided wherein the speed and number of compressors 302, 303 in operation are controlled in order to obtain a leaving liquid temperature setpoint. In response to an increase in the load in the chiller system 300, the algorithm determines if a compressor 302, 303 should be started and adjusts the operating speed of all operating compressors 302, 303 when an additional compressor 302, 303 is started. In response to a decrease in the load in the chiller system 300 with multiple compressors 302, 303 operating, the algorithm determines if a compressor 302, 303 should be de-energized and adjusts the operating speed of all remaining operating compressors 302, 303 when a compressor 302, 303 is de-energized.

摘要： Methods and systems for controlling the operation of condenser fans are provided. At most discharge pressures, the operation of the condenser fans may be controlled based on a capacity of the compressor system. To adjust operation of the condenser fans, the speed of the fans and/or the number or operational fans may be adjusted. The control of the condenser fans based on compressor system capacity may be overridden at compressor discharge pressures that rise above a high pressure level and fall below a low pressure level. At the high and low discharge pressures, the fan speed and/or number of operating fans may be adjusted based solely on the discharge pressure rather than on the compressor system capacity.

摘要： A refrigeration system is provided, such as for use with chillers. The system uses a tube-side condenser (24), such as a microchannel condenser, along with a shell-side evaporator (32) such as a falling film evaporator. A flash tank economizer (26) is disposed between the condenser and the evaporator, and an inlet valve (28) to the flash tank is controlled based upon subcooling of condensate from the condenser. The vapor exiting the flash tank may be fed via an economizer line (60) to a system compressor (50). Liquid phase refrigerant combined with some gas phase refrigerant exits the flash tank and is directed through an orifice (30) before entering the evaporator.
