Fan Performance Laws:
Fan performance is predicted using fan laws, which relate variables such as airflow (CFM), rotational speed (RPM), pressure (P), horsepower (Hp), fan wheel diameter (D), and air density (W). These laws apply to geometrically similar fans and include:
- Airflow varies directly with speed.
- Pressure varies as the square of speed.
- Horsepower varies as the cube of speed.
- Capacity and horsepower vary as the square of fan size.
- Speed varies inversely as fan size.
- Pressure remains constant with fan size changes.

Fan Selection Criteria:
1. System Requirements: Factors include airflow, static pressure, fan speed, brake horsepower, and sound level.
2. Pressure Considerations: Static pressure is the resistance of the system, influenced by components like ductwork and terminals. It varies as the square of airflow.
3. Stability: Fan operation should remain stable after disturbances. Instability can lead to system surge or fan stall.
4. Sound Considerations: Fans are major sound sources. Correct sizing and selection can minimize sound levels, especially in VAV systems.

Dirty Filtration Considerations:
When selecting fans for systems with dirty filters, consider:
- Adjusting fan selection for clean filter RPM but using motor horsepower for dirty filters.
- Using airfoil fans to minimize differences between clean and dirty airflow.

Heat Considerations:
Fan, motor, and drive heat contribute to airflow and pressure. Efficiency losses translate into heat, affecting power requirements and cooling/heating loads. Calculations for motor output and heat output are necessary to ensure proper sizing and performance.

Fan Application:
1. Forward-Curved Fans: Suitable for low to medium pressure applications, stable over a wide airflow range, and have the lowest first cost.
2. Airfoil Fans: Efficient at higher static pressures, with bhp decreasing as air volume decreases when using VAV devices.
3. Plenum Fans: Used in medium to high static pressure applications where discharge location flexibility is needed.

2. Airfoil Fans: Efficient at higher static pressures, with bhp decreasing as air volume decreases when using VAV devices.
3. Plenum Fans: Used in medium to high static pressure applications where discharge location flexibility is needed.
Plenum Fans: Plenum fans are used in situations with space limitations, discharge flexibility needs, or changing duct configurations. They have single-width, single-inlet construction and do not require a scroll to enclose the fan wheel. The entire interior of the plenum fan section is pressurized, and the fan shaft is parallel with the airflow. These fans are less efficient than double-width, double-inlet airfoil fans but are beneficial in reducing discharge sound levels. Pressure losses from duct takeoffs must be calculated and added to the system's external static pressure.
Duct Design Considerations: Proper duct design is crucial for fan performance. Straight discharge ductwork is recommended to allow airflow to develop a uniform velocity profile, aiding in velocity pressure recovery. For 100% recovery, the straight portion of the duct should be at least 2.5 times the discharge diameter for velocities of 2500 fpm or less.
Fan Control on Variable Air Volume (VAV) Systems: VAV systems reduce airflow to meet demand, saving energy. Fan control methods include terminal throttling and variable frequency drives (VFDs). VFDs modulate fan motor speed, offering greater energy savings and reduced sound levels compared to throttling methods. They are effective for systems with high turndown requirements.
Fan Types and Applications: Forward-curved (FC) fans are suitable for low to medium pressure applications, while airfoil (AF) fans are best for high capacity and pressure applications. Plenum fans are ideal for limited space or multiple duct applications. Each fan type has specific characteristics and applications based on pressure and airflow requirements.
Supply Fan Control: In VAV systems, supply fan control maintains constant static pressure in the supply duct. Variable frequency drives are preferred over inlet guide vanes for their efficiency and control over a larger airflow range. The DDC processor option helps maintain desired duct static pressure.
Indoor Air Quality (IAQ) Applications: CO2 demand-controlled ventilation (DCV) adjusts ventilation levels to maintain CO2 levels, achieving energy savings by ventilating only as needed. This feature adapts automatically without operator adjustments.
Coils: Coils in air-handling equipment are heat exchange devices that transfer heat between a medium and the airstream. They consist of tubes, fins, and headers, typically made of copper or aluminum, to enhance heat transfer efficiency.
Overview: This document provides technical specifications and guidelines for selecting and configuring air-handling units, focusing on components such as coils, headers, casings, and filters.

Air Handler Selection Guide
1. Unit Size Calculation: The coil face area is determined by dividing the design CFM by the maximum face velocity. For example, 12,000 CFM divided by 500 FPM results in a size of 24, rounded to Size 25.
2. Component Selection: Choose appropriate component sections based on the system requirements.
3. Dimensions and Weight: Determine the overall unit dimensions and weight. The height and width remain consistent across component sections for a given unit size.
4. Final Selection: Use Carrier’s AHUBuilder® program for finalizing selections, which aids in efficient air handler choice.

Features/Benefits (cont) Redefining flexibility Standard stacked fans and exhaust box sections reduce the footprint of the unit and ensure economical use of building space. Accessibility is required from only one side of the unit, increasing location options. This may result in floor space savings of 20% over competitive units. The use of non-staggered coils allows flat and cartridge style filter sections to maintain face velocities of 500 fpm or less at nominal airflow. Low velocity angle filtration sections typically have velocities of 350 fpm or less. Custom engineered for durability and longevity...
