O’Dell recently completed a design-build project for a group of net zero warehouses in Cambridge, ON. This project required a highly efficient and innovative solution to provide heating via VRF technology while addressing the challenges of heating outdoor air in a cold climate.
Challenges
The Meaford long-term care home is a new facility near Collingwood, Ontario, which features 77 beds and 24-hour nursing and personal care. O’Dell worked with the mechanical contractor on the project, McKenzie Mechanical, to supply rooftop ERVs and a ventilation kitchen system. Due to the large facility and large kitchen, they required a highly efficient demand control ventilation system.
The Solution
For the rooftop ERVs, we recommended (5) Valent Roof Top ERVs with packaged heating and cooling, and BACnet controls integration. With condition control so critical for an LTC, we made sure to include features with our units that could provide the building with the best performance. The packaged DX cooling system was supplied with hot gas reheat for dehumidification control and low sound ECM condenser fans. The gas heating system featured a 16:1 turndown to accurately control heating output.
Our Approach
The high-efficiency demand control ventilation kitchen system included the SpringAir Dynaflow kitchen hood, exhaust fan, MUA, and TruFlow control panel. The Dynaflow kitchen hood reduces energy costs by generating an air curtain with specific airflow rates based on the cooking appliances used to reduce the exhaust and MUA rate required. It also includes a comfort tuning dial which allows cooking staff to control how much fresh air is directed at them versus into the space. The TruFlow control panel monitors appliance usage and modulates the exhaust and make-up air accordingly in unison to maximize energy efficiency.
Conclusion
By implementing advanced ERV systems with precise control features and a high-efficiency kitchen ventilation system, O’Dell
ensured that the Meaford long-term care home operates with optimal performance and energy efficiency. Our tailored solutions addressed the unique challenges of the facility, providing a comfortable and well-regulated environment for residents and staff.
