VENTILATION AIR
POSSIBILITIES
By adding a hot water or electric heating coil, SpacePak becomes a year
round cooling and heating ventilation system with continuous blower
operation any time a building is occupied and needs to be ventilated.
This configuration makes SpacePak ideal for Makeup Air applications
commonly required in office complexes, libraries, schools, apartment
buildings and other commercial/institutional buildings.
TYPICAL HRV/ERV SPACEPAK SYSTEM INSTALLATION
NOTES:
1. Furnace/AC Blower is required to operate when ventilation from HRV/ERV is required.
2. A minimum separation of 24-inches (610 mm) is required between the two direct connections.
3. The exhaust air connection should be upstream of the supply air connection to prevent exhausting any fresh air.
4. Weatherhood arrangement is for drawing purposes only. Six feet (2 m) minimum separation required. Eighteen inches (460 mm) above grade minimum.
5. Due to the differences in pressure between the HRV/ERV and the equipment it is being connected to, the HRV/ERV’s airflow must be confirmed on site
using the balancing procedure found in the HRV/ERV manufacturers manual.
The benefits for commercial applications include:
• Compact design increases billable space
• Energy recovery compatibility
• Reduces overall cooling load
• Satisfies ASHRAE 62.1 Ventilation Requirements
• Lowers labor and equipment costs
• Enhances and preserves architectural integrity
