The Generic Unitary Air Loop consists of a fan component (on/off, constant volume or variable volume), a cooling coil component, a heating coil component, and a reheat coil as shown below. When a draw through configuration is required, the fan is placed directly after the heating coil. If dehumidification control is selected, a reheat coil component is also required. If the reheat coil is present and the dehumidification control type input is not specified as CoolReheat, the reheat coil will not be active.
Note: All of the fan and coil components are optional which allows these loops to be configured for fan-only, heating-only, cooling-only, or both heating and cooling.
The image above shows a unitary generic air loop connected to a Zone group with heat recovery and recirculation.
