Shown in the diagram.
The ahu s and fcu s are basically boxes with fans inside that suck air in from the building and push it across the heating or cooling coils to change the temperature.
2 pipe systems the 2 pipe water distribution system is used with both heating and cooling equipment con taining water coils.
Fan coil units are typically selected and sized to heat and cool a small zone with specific load requirements.
Hanger supports from wall.
Chilled water cooling co ils shall be selected to provide a 15 f or higher temperature difference between leaving and entering water temperatures and a minimum of 57 f leaving water temperature at design conditions.

The chilled water branches off the risers into smaller diameter pipes which head to the fan coil units fcu s and air handling units ahu s to provide air conditioning.
All vh units include two flexible stainless steel braided hoses and ball isolation valves per coil.
Unions are not available separately.

Chilled water would need to be redesigned so they are not prohibitively large expensive or space consuming.
Exceptions to section 6 5 4 7.
A chilled water system is a cooling system in which chilled water is circulated throughout the building or through cooling coils in an hvac system in order to provide space cooling.
A zone may consist of a single undivided space a partitioned room or multiple rooms with similar smaller loads that together add up to the total load the fan coil unit is designed to handle.
When ordered unions are installed at the water coil and are available on vav products and all fan coil units except vh.
