SynC · Topic
These are the standards in the SynC Standards library that cover Fan Coil 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.
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.
Variable refrigerant flow (VRF/VRV) air-conditioning and heat pump systems serving commercial, institutional, and multifamily buildings, in which one or more inverter-driven condensing units circulate refrigerant through a piped network to multiple indoor fan-coil units, each metered by an electronic expansion valve. Covers heat pump (cooling-or-heating) and heat recovery (simultaneous cooling and heating) systems, air-cooled and water-source (water-cooled) condensing units, ducted and non-ducted indoor unit types, branch controllers and refrigerant selector boxes, A2L refrigerant safety and leak detection, and coordination of a dedicated outdoor air system for ventilation.
