Venmar is a Heating, Ventilation, and Air Conditioning company

Two Canadian offices: Saskatoon and St-Léonard-d'Aston, Quebec

Specialize in manufacturing commercial HVAC units

Their main focus is on efficiency and energy recovery methods

1. Enthalpy wheel not always needed: Most effective for large temperature

differences Wheel causes pressure drop and consumes

energy

2. Accurate flow rates measurement needed:

Cost effective means of measuring airstreams is needed

Integrated into control system to control air flow

1. Bypass the enthalpy wheel: Determine increased flow rate due to

decrease in pressure drop Determine annual energy savings due to

reduced fan speed

2. Flow measuring device: Develop cost effective means of measuring

airstreams Requires an accuracy of 8% Ensure compliance with existing control

system
