Unlike many designers, our low
temperature air buildings only provide low temperature air on the peak load days - the
supply air temperature is continually reset as required to minimize tenant complaints and
fan and chiller plant energy, in that order. It
does no good to have minimum fan energy if the tenants are always cold in the interior
zones, and the system is always in reheat. Reducing
the overall cost of operation while maintaining tenant comfort is the driving goal.
The use of
low temperature air can reduce fan energy by 50% or more in a facility, when coupled with
our proprietary control system sequences of operation.
On
many buildings that were originally designed with inadequate supply air volumes to meet
the needs of todays computer-laden tenants, the conversion to low temperature air
distribution is an extremely
cost effective means to satisfy the cooling loads. |
