cooling Full-load Air Volume Rate for Ducted Units. The manufacturer must specify the Cooling Full-load Air Volume Rate.Use this value as long as the following two requirements are satisfied. First, when conducting the Aor A2test (exclusively), the measured air volume rate, when divided by the measured indoor air-side total cooling capacity, must not exceed 37.5 scfm per 1,000 Btu/h [0.06 m3/s per 1,000 W]. If this ratio is exceeded, reduce the air volume rate until this ratio is equaled. Use this reduced air volume rate for all tests that call for using the Cooling Full-load Air Volume Rate.The second requirement is as follows:
