There is a great deal of concern over best practices in the design and operation of building HVAC systems in light of the recent worldwide COVID-19 pandemic. AAON shares these concerns and recommends following WHO, CDC and ASHRAE guidance on the operation of commercial buildings during this time. The need for healthy buildings has changed HVAC system design and operation going forward.
What are the most critical aspects of indoor air quality and how does AAON equipment meet those needs? Humidity control, fresh air intake, filtration, coil cleaning, and air disinfection.
Contact your local AAON representative for more information about Indoor Air Quality solutions with AAON systems.
AAON can offer an enthalpy energy recovery wheel which conditions fresh intake air both by transferring humidity and sensible heat from the outside air stream to the exhaust air stream or vice versa. AAON also offers DDC economizers which can include a CO2 override to ensure the CO2 levels within the space are always in the acceptable range.
Filtration, Coil Cleaning, and Air Disinfection – All these options work by removing undesirables from the return air stream for a cleaner supply air to the building.
AAON has offered modulating hot gas reheat for years for precise humidity control of the space. Operation of a variable speed compressor or variable-capacity compressor can increase the precision of humidity control while also provide unit efficiency.
Modulating Temperature and Humidity Control - Discusses the benefits associated with the modulating capacity scroll compressor and the modulating humidity control options. Benefits include energy savings, extended compressor operating life and improved temperature and humidity control, when compared to on/off systems. A comparison of the power usage of hot gas bypass and the modulating capacity scroll compressor is shown. Also includes a section on applications of modulating temperature and humidity control.
