Often, ...the surgeon expects a lower room temperature than that stated in guidelines. for a 450 ftÂ² (42 mÂ²) surgery room with a 10 ft (3 m) ceiling height, 15 ACH equates to 1,125 cfm (531 L/s) of supply air.ensible heat added by the adsorption process raises the supply-air dry-bulb temperature to 55Â°F (13Â°C). Mixed air (MA) entering the regeneration side of the wheel is at a lower relative humidity (about 50%).
Smocking may be done in many sophisticated patterns. A. Cable stitch: a tight stitch of double rows that joins alternating columns of gathers. B. Stem stitch: a tight stitch with minimum flexibility that joins two columns of gathers at a time in single overlapping rows with a downward slope.
