Methods of Testing Propeller Fan Vibration----Diagnostic Test Methods
Establishes laboratory and on-site diagnostic test methods for identifying causes of vibration problems involving direct-driven propeller fans for condenser cooling in air-conditioning units, heat pumps, and chillers. Applies to all types and sizes of air-conditioning units, heat pumps, and chillers using direct-driven 250 mm to 750 mm (10 in. To 30 in.) diameter propeller fans. Does not cover system vibration problems excited by the compressor in the unit or by external sources. SI units of measurements.
