Getting air to the breathing zone in a pool

Gas detectors should be mounted upright on a vertical surface like a wall, column or beam - do not mountВ upside down, sideways or flat on the floor.

If you have any questions, please ask your Regional Sales Manager or our Technical Service Department. Some applications may require the sensor to be mounted at a different height than indicated below. The air shower principle creates a zone of clean air around the worker and pushes the contaminant plume away from the breathing zone. For example, a sensor mounted 30 feet (9 m) off the floor will be difficult or even hazardous to service. Pay particular attention to 'dead air spots' where there is little or no air movement.Д¬onsideration should be given to accessibility for calibration when locating sensors. They should be placed in areas where there is good air circulation, but not in the path of rapidly moving air. Sensors should not be placed near ventilation fans or openings to outside. 62.1 does not specifically define outside air turnover rates. For example, near the compressor or piping. Keywords: Pool, Airflow, Turnover rate, Breathing zone. Sensors should be placed near the source of the gas if possible. Zones with intermittent interruption of supply air: The average outdoor airflow supplied to the breathing zone over time (T) shall be not less than the breathing zone outdoor airflow (V bz) calculated using Equation 403.2.1.

This is a good default location for sensors, as many gasesВ often disperse well in air. and amount of fresh air per occupant delivered to the breathing zone. The sensor mounting height depends the type of application and on the density of the target gas relative to air.В Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the 'breathing zone' 4 - 6 ft (1.2 - 1.8 m) from the floor.В The breathing zone refers to the area 4 - 6 ft (1.2 - 1.8m) from the floor, where most human breathing takes place. 1) Short circuiting is when air is supplied into the natatorium and fails to reach much of the room because it shortcuts back into the return vent beforehand. Investigations of indoor air quality (IAQ) often fail to identify any harmful. в–є What should the mounting height of the sensors be?
