Re: [EnergyPlus_Support] will the higher cooling coil setpoint affect indoor air temperature control?
You need to maintain enough capacity to meet the load. If the supply air
temperature is increased (delta T from supply air to room air is lower),
the air flow rate should also be increased.
Capacity Q = mCpDeltaT
