Jet Range Recommendation
NOTE:
1. The maximum spread width of the unit jet flow is about 40% of the jet range. Therefore, unit deployment should take into consideration the air flow spread angle,
and the distance between units should not be too large.
2. The units can be deployed on a single side or on opposite sides. If neither the deployment can meet the jet range, an induction fan can be adopted to continue the
air supply. The induction fan is deployed by every 4 to 6 meters in vertical direction, and by every 6 to 10 meters in horizontal direction.
The thermal performance parameter calculation of the ordinary ceiling type unit is the same with that of the jet type air
handling unit adopting the spherical nozzle. Design selection mainly includes the calculation of air flow organization. For a
specified project, the proper jet type air handling unit needs to be selected after the air supply distance, unit installation height,
air supply temperature, and air supply volume are determined, and the cold and hot air flow supplied by the unit must meet the
following requirements:
1. The cold and hot air are sent to the specified location.
2. The cold jet flow does not drop down during the supply process to avoid causing discomfort to people.
3. The hot air can be sent to the required distance and location.
4. Temperature difference meets the design requirement.
Design selection must take into account the mutual impact of the multiple air supply nozzles of the unit. The spread of the
jet flow is approximately 0.4 times wider than the jet range. An appropriate configuration is to make the unit deployment density
slightly smaller than the diffusion width. If the unit is installed closely to the ceiling, the impact of adhesion should also be
considered. The jet range of the attached air flow is 1.4 times larger than the common air flow.
Based on the performances of the unit and the spherical nozzle, the recommended horizontal air supply range (unit: m) of
various types of air handling units is as follows:
