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 single- duct VAV 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.

VAV-SVN01E-EN, Trane specifications

The Trane VAV-SVN01E-EN is an advanced variable air volume (VAV) system designed to optimize indoor air quality and energy efficiency in commercial buildings. This system is part of Trane’s commitment to offering reliable, innovative HVAC solutions that meet the demands of modern architectural designs and energy standards.

One of the main features of the VAV-SVN01E-EN is its ability to control air flow based on occupancy and environmental conditions. This ensures that energy is used efficiently, as airflow can be adjusted to match real-time needs, rather than operating at a constant rate. The integration of intelligent sensors allows the system to adapt dynamically, leading to both reduced energy consumption and improved comfort for building occupants.

The technology behind the VAV-SVN01E-EN includes advanced digital controls and integration capabilities. These controls enable the system to communicate seamlessly with building management systems (BMS), allowing for centralized monitoring and management. This interconnected approach not only enhances operational efficiency but also enables predictive maintenance, helping facility managers identify and address potential issues before they become problematic.

Energy efficiency is further enhanced through the use of VAV technology, which reduces the amount of conditioned air delivered when spaces are unoccupied or when less cooling or heating is required. This tailored approach contributes to lower energy costs and supports sustainability initiatives by decreasing the overall carbon footprint of the building.

Key characteristics of the Trane VAV-SVN01E-EN include its compact design, which facilitates easy installation in existing spaces without significant modifications. The unit is also designed for low sound levels, ensuring that it operates quietly, contributing to a more pleasant indoor environment. Moreover, the VAV system is engineered to be reliable and durable, with rigorous testing and high-quality components ensuring long-term performance.

In summary, the Trane VAV-SVN01E-EN stands out in the field of HVAC solutions, bringing together advanced technology, energy efficiency, and user comfort. Its features are tailored for modern building requirements, making it a preferred choice for facility managers aiming to enhance indoor air quality while reducing operational costs.
