Single 3 way water coil piping detail with 3 way control valve. Fan coil units are typically selected and sized to heat and cool a small zone with specific load requirements. 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. All vh units include two flexible stainless steel braided hoses and ball isolation valves per coil.
Unions must be ordered on both coils of 4 pipe units. 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. 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. Exceptions to section 6 5 4 7.

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. The principal objectives of chilled water pumping system selection and design are to provide the required cooling capacity to each load to promote the efficient use of.
It is equally useful for room fan coil units and medium or large central air. When ordered unions are installed at the water coil and are available on vav products and all fan coil units except vh. Unions are not available separately. 2 pipe systems the 2 pipe water distribution system is used with both heating and cooling equipment con taining water coils.
