Information
Single-Duct Units |
Figure 1 –Typical Single-Duct Units |
|
The basic unit consists of a sheet metal |
|
|
casing with an air valve, which is used |
|
|
to modulate the air being delivered into |
|
|
the occupied zone.The unit is designed |
|
|
to modulate either cooling or heating |
|
|
air between the temperatures of 40°F |
|
|
and 140°F.Air enters the air valve |
|
|
through the round or rectangular inlet |
|
|
and exits into the sheet metal casing to |
|
|
be distributed to the zone either |
|
|
through integral round outlets in the |
|
|
casing or through rectangular duct |
|
|
attached to the discharge of the unit. |
VCCF |
|
The basic unit can also be ordered with |
||
|
||
factory-mounted electric or hot water |
|
|
heating coils attached to the discharge. |
|
|
(See Figure 1.) |
|
|
These re-heat units are used primarily |
|
|
to reheat air-to-zone temperature when |
|
|
the load in the occupied space is low. |
|
|
Primary air is modulated through the |
|
|
VariTrane air valve by rotating the |
|
|
damper blade. All air valves have a |
|
|
round/rectangular inlet for easy fit-up |
|
|
with incoming ductwork. |

Dual-Duct Units
Dual-duct units provide two air valves: one as heating primary air and the other as cooling primary air. Both discharge into the common outlet, which leads to the zone being controlled. (See Figure 2.)
The units are provided with a slip and drive rectangular duct connection or can be ordered with integral outlet plenum.
Sequencing of the hot and cold air valve is dependent upon job requirements. One typical control is the valves working in conjunction with each other to respond to zone temperature.
When the cooling valve becomes fully closed or reaches a specified minimum, then the heating valve will begin to modulate or vice versa.The typical result is that air flowing to the zone varies from the maximum down to a minimum and back up to a maximum as the load varies and as the controls would cause one air valve to close and the other to open.
Another typical application is when the unit provides a constant volume to the zone.When the zone sensor is tied directly to the heating valve, it will modulate the heating valve according to the zone temperature.
When the heating valve is fully closed or there is a call for cooling in the zone, the cooling valve will be at constant supply. As the space becomes too cool, the heating valve will modulate open, decreasing the cooling valve flow.The typical result is that the air flowing into the zone stays at a constant flow whether the unit is heating or cooling.

Information
Fan-Powered and Fan-Powered Low-Height Units
VariTrane fan-powered and low-height fan-powered units can be either parallel or series, with or without re-heat. (See Figure 3.)
The fan on a series unit runs continuously whenever the main air handler unit is in operation.There are various options for starting the fan.The fan can be started three ways: 1) remotely, 2) by a duct pressure switch, or 3) by a combination of both.The particular fan control method may vary from unit to unit, depending upon job needs.
Typically, the heater is off while the air valve modulates primary air and responds to zone temperature. If zone temperature decreases to the point where a decrease in primary air will not maintain the desired temperature, the re-heat will be activated to increase the temperature of the discharge air.
On a parallel unit, theVariTrane air valve delivers primary cooling air to the unit outlet.When the space temperature decreases beyond air valve control, the fan is turned on as the first stage of heat.The fan delivers plenum air from above the occupied space to the unit outlet, which is mixed with primary air and delivered to the occupied space.
Note: Either the fan, the air valve, or both can deliver airflow into the occupied space. In order to prevent primary airflow from exiting through the fan when the fan is not running on a parallel unit, a back draft damper is provided. When the fan is not running, the efficiency of this system is the same as a standard singleductVAV unit.
Typically, the control systems applied to parallel units cause the air valve to close to zero or a minimum flow before the fan is activated. After the fan is activated, the optional heat will be activated upon further reduction in zone temperature.Therefore, minimal primary air is mixed with the heated air.
VariTrane fan-powered unit fan sizes 02SQ–05SQ and 08SQ–10SQ were performance tested at .12 in. w.g. and sizes 06SQ and 07SQ were tested at .15 in. w.g. Units are not designed to operate unducted and below these tested static pressures.
Note: Fan-powered units are available with rectangular discharge connection only. The optional heater is mounted on the discharge of the unit. Hot water coils are connected to either the plenum inlet or on the discharge on parallel units, and to the discharge of series units.

Unit
Installation
Due to their weight, theVAV terminal units should be suspended from the uppermost ceiling, independent of the false ceiling grid. Suspension devices are to be supplied by the installer. Units must be installed level and upright. Failure to level the unit properly may prevent proper operation of the controls and/or terminal unit. Units are not designed to be installed vertically. Consequently, this will also void the UL ratings and any warranty on the unit.
Single-Duct
Depending upon the size and weight of the single-duct unit, it may be capable of being supported by the ductwork that is connected to it. No hanger brackets are provided on these units since the unit should be supported by means of a hanger strap.The hanger strap should be secured directly to the unit casing as shown in Figure 4.
For cooling only single-duct units or single-duct units with hot water coil, the unt may be rotated 180° for opposite side connections.
For units with electric heat, the unit must be ordered from the factory designating either rightor left-hand connections.

Single-Duct Hanging
Recommendations
Dual-Duct
Dual-duct units should be supported by either hanger straps or by using a threaded rod in conjunction with the hanger brackets that are provided on the unit. See Figure 5.
