Mixing box damper testing." ASHRAE Transactions 104(2):1226.
As shown in Table 1, an example of
mixing box (dampers) illustrates the typical categories in a component module setup.
Then the effect of heating/cooling systems is removed from the DAT, and the performance of the
mixing box is evaluated by analyzing its functionality effect on the filtered DAT.
The PmxC[O.sub.2] was measured using a fast
mixing box and side-stream capnography, avoiding the complex cross-multiplication and integration of in-line flow and PetC[O.sub.2] measurements required in other software.
Of the burglary in April last year, she said that someone forced the door of the victim's room in the house while he was out and stole his DJ mixing decks and
mixing box.
APAR also successfully identified several occurrences of faults with the
mixing box dampers.
Once we even designed our own twin shaft
mixing box and suspended it from a Cat dozer."
Each zone has its own upstream and downstream air flows; ambient air is drawn through heat exchangers and mixed in a specially-designed
mixing box. It is then passed through the fries, which are carried on a plate belt.
Pure argon was admitted at a constant rate from a mass controlled source (tylan FC 260 USA) into the
mixing box in order to calculate the respiratory volume |5~.
For example, measurements of the supply air-flow rate from air handling units (AHUs), the outdoor air-flow rate into air handlers, the temperature of the mixed-air leaving the AHU
mixing box, and the chilled water flow rate through cooling coils are usually not available or not accurate enough for HVAC control and fault detection.
