VENTILATION System for hatchery By Dominic Babineau Engineer

VENTILATION System for hatchery By Dominic Babineau, Engineer Jamesway Incubator Company Inc.

-First stage of filtration -30% efficiency -Large access door -Pressure differential reading -Large access door

-Coil design with less than 10 fin per inch -Air flow speed less than 400 FPM -Stainless steel condensation pan -Easy to clean

-Direct drive fan (no belt to change) -8% more efficient then belt drive fan -High efficiency motor -Low speed motor for longer life -VFD for room pressure control and longer life -Large maintenance access

-Second stage of filtration -80 -85 % efficiency -Installed on positive side of the unit -Cleaner air

-No free wire -Washable unit

-Control section -Positive side -Clean and tempered environnement -Speed controller (VFD) mounted -Tool plug for maintenance

DEHUMIDIFICATION OF THE AIR Design temperature -93, 7 F DB -74, 6 F WB -ASHRAE Reference Room conditions -70 F to 85 F -73 F optimal temperature -50% Humidity -Jamesway requirement

DEHUMIDIFICATION OF THE AIR

Pressure control of the air Speed controller (VFD) -Quicker reaction time than damper -Better precision of control -Easier trouble shooting -Easier adjustment

AHU Benefit • • • Less maintenance Filter maintenance alarm Better air quality 80% efficiency Possibility to heat the fresh air with the chiller heat rejection Washable Lower electrical requirement No recirculation, less chance of contamination. Possibility of backup Only one spare part to keep in inventory (motor) Control system specially design for energy saving with energy optimization
