Round VAV Terminal Units

SDR

STEKON SDR; controls the volume of conditioned air into an occupied space in response to a thermostat or Building Management System control signal with minimal pressure drop and low sound levels. Thanks to its specially designed multipoint air flow sensor, terminal senses the air flow changes precisely and instantly and adjust the damper position independently of pressure.

Depending on environmental changes such as increased occupancy or cooling demand, VAV Unit adjusts air flow according to signals from a local or central control system, providing good air quality whilst avoiding excessive ventilation.

What Are VAV Terminal Units? | Efficient and Customizable Climate Control

VAV (Variable Air Volume) terminal units are a key component in modern HVAC (Heating, Ventilation, and Air Conditioning) systems, designed to provide energy-efficient climate control while enhancing indoor comfort. Unlike traditional constant air volume (CAV) systems, VAV units adjust the amount of air supplied to a space based on the current demand. This results in significant energy savings and more precise temperature control in commercial and residential buildings.

Benefits of VAV Terminal Units:

  • Energy Efficiency: By modulating airflow according to the room’s needs, VAV systems minimize energy consumption, making them ideal for large spaces or buildings with fluctuating occupancy.
  • Enhanced Comfort Control: VAV units allow for independent temperature control in different zones, maintaining optimal indoor comfort for all occupants.
  • Quiet Operation: Designed for low-noise performance, VAV terminal units ensure a peaceful environment without disruptive noise from the HVAC system.
  • Flexible Design: Available in various sizes and configurations, VAV units can be customized for individual rooms or larger, multi-zone buildings.
  • Ease of Installation and Maintenance: VAV units are known for their modular design, making them easier to install, operate, and maintain over time.

How Do VAV Terminal Units Work?

VAV terminal units control the amount of air distributed into a room or zone by modulating dampers in response to temperature sensors. When the room requires cooling or heating, the VAV unit adjusts the damper position to increase or decrease the air volume delivered, ensuring precise temperature control. This flexibility makes VAV systems particularly effective in large buildings where environmental conditions can vary across different areas.

Common Applications of VAV Terminal Units:

  • Office Buildings
  • Hospitals
  • Hotels
  • Shopping Malls
  • Educational Institutions
  • Airports
  • Industrial Facilities

VAV vs. CAV (Constant Air Volume) Systems:

  • Air Distribution: CAV systems deliver a constant flow of air regardless of temperature changes, while VAV systems adjust airflow based on real-time demand.
  • Energy Consumption: VAV terminal units are more energy-efficient because they only deliver the necessary amount of air to maintain the desired temperature, reducing energy waste.
  • Occupant Comfort: With VAV units, each zone or room can be controlled independently, ensuring that occupants in different parts of a building experience optimal comfort.

Types of VAV Terminal Units:

  1. Single-Duct VAV Units: These units regulate airflow through a single duct and are commonly used in commercial buildings for both cooling and heating.
  2. Fan-Powered VAV Units: These VAV units contain a small fan that helps to re-circulate air within the space, improving air distribution and comfort.
  3. Dual-Duct VAV Units: With two separate ducts (one for hot air and one for cold air), these units provide enhanced temperature control, making them ideal for spaces requiring precise climate regulation.

Key Considerations When Choosing VAV Terminal Units:

  1. Room Size and HVAC Requirements: The size of the room and its ventilation needs will determine the required VAV unit capacity.
  2. Energy Efficiency: Look for units with high energy efficiency ratings to minimize long-term energy costs.
  3. Installation and Maintenance Requirements: Opt for units that are easy to install and maintain to reduce operational disruptions and maintenance costs.
  4. Noise Levels: For noise-sensitive environments like hospitals and offices, choose VAV terminal units that offer low-noise operation.

Why Choose VAV Terminal Units for Your Project?

  • Cost Savings: Lower energy bills due to optimized air distribution and reduced energy waste.
  • Scalability: Whether it’s a single room or an entire building, VAV systems can easily scale to meet the needs of any project.
  • Sustainability: VAV terminal units support green building standards by lowering the overall carbon footprint of HVAC systems.
  • Precision: Achieve exact temperature control for different zones, enhancing comfort while optimizing efficiency.
