Learned from the experimental result, when the temperature of the in-flow cold water controlled at 7C, the air flow from this LTD-VAV FCU could be adjusted from 0.33 (700CFM) to 0.14 (300CFM) in a free rate. The variation rate of air conditioning capability is 84.8% from its maximal to the minimal. Meanwhile, the air conditioning capability is ranging between 5.26 kW and 0.8 kW.

By managing capacity supply comply with workload control, the LTD-VAV FCU hence sustain the temperature in the room to a fine range. And the temperature difference between air outflow and inflow can be minimized to 3C.
