A new standard fromASHRAEwill assist the marine industry in evaluating system performance results and installation techniques for shipboard HVACR systems. ANSI/ASHRAE Standard 151-2002, Practices for Measuring, Testing, Adjusting and Balancing Shipboard HVAC&R Systems, provides uniform and systematic practices for the marine industry. The standard describes methods for measuring temperature, humidity, enthalpy, current, wattage, voltage, rotation, fluid flow, heat flow, pressures, and sound and vibration levels in HVACR systems.
