Case Study Report

Location: Minnesota

Application Type: Parking Garage

Design: This underground parking facility received limited amounts of natural ventilation air, necessitating mechanical ventilation to prevent the buildup of noxious fumes. A direct fired heater was installed to properly ventilate the space and provide comfortable space temperatures during the winter months.


Advantages:

  1. 100% efficient direct fired burner provides heating and ventilation
  2. Space thermostats prevent cold zones
  3. Interlocked NO2 and CO detectors prevent accumulation of vehicle emissions
  4. Constantly meets ASHRAE 62.1 fresh air requirements while exceeding ASHRAE 90.1 efficiency standards
  5. 30:1 turndown ratio allows wide range of burner modulation
