• A.Option C - Whole facility measurement
• B.Option A - Retrofit isolation: key parameter measurement
• C.Option B - Retrofit isolation: all parameter measurement

• E.Option E - Stipulated savings

A facility has the thermal cooling load profile shown in the table below. The utility rate tariff has an on-peak time-of-use billing period that begins at 10:00 a.m. and ends at 7:00p.m. Calculate the storage capacity required for a load-shifting operating strategy, to make sure that no thermal cooling Is generated by the chiller during the on-peak utility rate period.

[Question from the previous image, which was about storage capacity for load shifting, but the table was missing]

• A.66 GJ
• B.48 GJ
• C.72 GJ
• D.84 GJ

What instrument determines flow rate by measuring pressure differential?

• B.Pitot tube
• C.Infrared camera
• D.Hot-wire anemometer
• E.Ultrasonic flow meter

What is the uniform series present worth factor (P/A, i%, n) for an annual interest rate of 15% and a lifetime of 20 years?

• A.4.676
• B.6.259
• C.0.214
• D.0.160

• B.Decreasing supply air pressure
• C.Raising the air pressure
• D.Reducing the air distribution pipe size
• E.Reducing the capacity of the compressed air receiver tanks
