System performance characteristics of a helical rotary screw air-cooled chiller operating over a range of refrigerant charge conditions.

Author(s) : BAILEY M. B.

Summary

The paper presents a study involving the operation of a 70-ton helical rotary, dual-circuit, air-cooled chiller while three independent variables are experimentally altered. It examines the three independent variables on superheat and subcooling temperatures, chiller kilowatts per ton, chilled water setpoint temperature control, and compressor suction and discharge pressures. The consequences of refrigerant undercharge or overcharge are fully investigated and documented.
