Fan Coil Units
These are the standards in SynC Standards 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, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 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.
Standards
- Split-System Air Conditioners and Heat Pumps
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) Systems
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.
