SynC · Topic
These are the standards in the SynC Standards library that cover Air Handling Units. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Central station air handling units that condition air and deliver it through a field-installed duct distribution system, whether factory-assembled in shipping sections or field-erected from components. Covers indoor and outdoor units, constant-volume and variable-air-volume systems, single-zone and multiple-zone arrangements, mixed-air units and dedicated outdoor air units, and units serving commercial, institutional, industrial, healthcare, and laboratory occupancies.
Specifying matched split-system unitary air conditioners and air-source heat pumps, including ducted split systems (outdoor condensing/heat-pump unit matched to an indoor air handler or coil) and single-zone ductless mini-split systems, serving residential, light-commercial, and small-zone applications.
