HVAC systems for airside economizer high limit shutoff control strategies.

ASHRAE Standard 90.1 references four airside economizer high shutoff control strategies depending on the climate zone.

  1. Fixed Dry Bulb Temperature
  2. Differential Dry Bulb Temperature
  3. Fixed Dry Bulb Temperature & Fixed Enthalpy
  4. Differential Enthalpy and Fixed Dry Bulb Temperature

The ApacheHVAC file has HVAC systems with all four control strategies modeled.
