Each dual-staged packaged unit had a single constant-speed supply air
fan and two refrigeration systems with independent compressors, evaporators, condensers, condenser fans, and expansion devices.
Local thermal discomfort, which may be easily caused by supply air
heating, was not studied, because the simulations showed heating need outside occupied hours, as reported in Table 2.
In case 1, cold supply air
did not affect thermal plumes above occupants.
The supply air
temperature is an average of the three plenums.
Darchem Engineering will supply air
intake and exhaust systems for the two 65,000t carriers
can be introduced to the space warmer (typically at 62-64[degrees]F) since the diffusers are located in the occupied zone, and heat generated by ceiling level lights is removed, and thus is not included when estimating building cooling loads.
Systems can be designed to maintain vented exhaust air, HEPA filtered supply air
, or temperature-controlled, recirculated air.
The MAX 9000 Ceiling Module supply air
is pre-filtered through a 1" dust guard.
in the 20800 block of Placerita Canyon Road on Thursday and quickly destroyed about $10,000 worth of paper and plastic filters used to supply air
to turbines, fire officials said.
Finally, in a recent HPT implementation at a Minnesota hospital, energy from exhaust air could be recovered year-round to precool or preheat supply air
, but the hospital required that the supply air
not be contaminated by exhaust air.
The supply air
in the two acting areas are exchanged.
When the outdoor air humidity ratio is higher than the humidity ratio at desired return air conditions, usually 24[degrees]C (75[degrees]F) and 50% relative humidity (RH), the cooling coil of AHUs operates at completely wet conditions and supply air
is nearly saturated.
