Oval Vav
Oval Vav
Variable Air Volume (VAV) systems improve energy efficiency by supplying conditioned air at a constant temperature while varying the airflow to meet the changing requirements of each zone. Compared to conventional HVAC systems, VAV systems offer energy savings of up to 30%, improved occupant comfort, lower installation costs, and enhanced operational efficiency. COSMOS VAV Terminal Units are precision-engineered to deliver accurate airflow control and reliable performance across a wide range of HVAC applications.
Product Introduction
Variable air volume (VAV) systems were developed to be more energy efficient and to meet the varying heating and cooling needs of different building zones. A zone can be a single room or group of rooms with the same heat gain and heat loss characteristics. VAV systems can save as much as 30% in energy costs as compared to conventional dual duct systems. In addition, they are economical to install and to operate. Duct sizes and central air handling units are smaller and the design
and installation is generally much simpler.
VAV units, or Variable Air Volume systems, supply constant temperature air to an area while the volume of air varies as opposed to a conventional HVAC system which has constant volume and varies the air temperature. Variable Air Volume Systems supply a constant temperature to an area and vary the volume as opposed to a conventional HVAC system which supplies a constant volume and varies the air temperature. VAV terminal units provide variable air volume (VAV) control beyond the typical single duct box. They are specifically designed for precise air delivery throughout the entire operating range, regardless of the installed inlet conditions. They also offer improved space comfort and flexibility for a wide variety of HVAC applications.and installation is generally much simpler.
General Information
COSMOS make single duct air terminals are designed to regulate the flow of conditioned air in single duct air distribution system. Air terminals include; Basic air terminal, Air terminal with sound attenuator for conventional ducting where Air terminal with rectangular inlet/discharge, Air terminal with flat oval inlet/discharge, Air terminal with circular inlet/discharge for exposed ducting.
Terminals are available with wide range of standard control sequence and work equally well in constant volume and variable volume system.
COSMOS VAV terminals provide variable volume (VAV) control beyond the typical signal duct box. They are control beyond the typical signal duct box. They are specifically designed for precise air delivery throughout the entire operating range, regardless of the installed inlet conditions. COSMOS VAV terminals provides the ultimate in airflow control with patented AK Star TM airflow sensor. No other sensor in the industry can match the AK Stars ability to quietly and precisely measure airflow. Accurate airflow measurement is basis of air flow control.
COSMOS VAV inlet design and AK Star TM flow sensor ensures accurate control, even when space constraints do not permit long straight inlet duct runs to the terminal. The highly amplified velocity pressure signal from the AK Star TM inlet flow sensor allows precise airflow control at low air velocities. COSMOS terminals and accessories are wired in compliance with all applicable requirements and tested in accordance with AHRI standard 880.

VAV PID Oval Module
For any PID VAV, air flow measurement is important to ensure better performance. Cosmos Flat Oval VAV module has specially designed inlet cone (oval to round adapter). This facilitates turbulence free air pattern at the VAV inlet, enabling precise air flow reading, even if the air flow rate is 20% of the set air flow. The Ak Star cross flow grid at the VAV inlet amplifies the signal upto 3.5 times. This adds to the accuracy of air flow measurement and super fine performance of Cosmos VAVs.
COSMOS introduces New VAV Module series which facilitates Ease of Installation & Precise Performance of VAV system. It enhances to the aesthetic values of exposed ducting with blemish free (no transition pieces) installation procedure. COSMOS VAV are specially designed for precise air delivery throughout the entire operating range regardless of installed inlet conditions. COSMOS VAV inlet design and AK STAR TM flow sensor ensures accurate airflow control, even when space constraints do not permit long straight inlet duct runs to the terminal.
