16 Twin Duct VAV Terminal Units Twin Pack - TPO 225 Twin Duct VAV unit System Description Twin Pack VAV units are designed to clip directly onto ductwork carrying two streams of conditioned air, namely Cold and Neutral air supplies. The ductwork is of a sandwich configuration. The VAV s function is to mix the two air supplies in response to Room Temperature and Prescribed Terminal Airflow requirements. As in the case of the standard VAV range, Twin Pack units employ Celmec s well proven Aerofoil Valve design. This is a critical feature having a linear flow/stroke characteristic ensuring precise control response and accurate mixing of the two air supplies. The Twin Pack system is further enhanced with its unique airflow sensing station which is independant of upstream and downstream system pressures and unaffected by turbulent air entry conditions. There is no equal to Celmec s patented Twin Pack VAV system.

17 VAV Terminal Units Air Control inear Control Accurate air flow control is provided by the Aerofoil type valve, configured to accept a standard 90 stroke, direct drive actuator. The valve has a near linear flow/stroke relationship as shown. AEROFOI VAVE AIR FO BADE DAMPER DAMPER POSITION aminar Flow The Celmec Aerofoil Valve produces laminar air flow patterns, in any position, as shown. This ensures even air distribution across the face area of the duct, or across the downstream HH heating coil or electric element. AEROFOI VAVE Air Resistence Due to the Aerodynamic nature of the valve, static regain is achieved, permitting more efficient use of fan energy, as well as allowing flexibility in future adjustment, should additional air flow be required

18 VAV Terminal Units Acoustic Performance Radiated Noise As a result of exhaustive Research and Development work, testing and experience with numberous VAV Air Valve configurations Celmec has developed a method of significantly reducing low to mid frequency noise and shifting high frequency noise energy away from Casing Break-out, towards the less critical direction of Unit Discharge, by means of reflection. Consequently, the above technology and acoustic expertise have been combined by Celmec to create a full range of VAV Terminal Units which offer greatly reduced Radiated and ow Frequency Noise evels compared to conventional systems.

20 VAV MAINTENANCE GUIDE As with all equipment, periodic checks should be carried out on variable air volume terminal units. e suggest the following items be attended to at six monthly intervals. 1. Electrical components: Isolator / Circuit Breakers, Fan Relays, Heater Relays and Contactors. Check operation and any sign of overheating, loose terminations, relay/contactor chatter or excessive switching, fused contact points or signs of deterioration of contact points. 2. Fans / Fan Motors / Fan Bearings No maintenance required. Check operating Voltage, to be no less than 130V. 3. Primary Air Damper No maintenance required. Operate damper from fully closed to fully open. Check for free operation. 4. Actuator Check operation and if stroked correctly. Stroking should be carried out, starting with the damper in fully closed position. Check motor to shaft fixing to ensure positive response and full closure. 5. Controls Refer to the control manufacturer s recommendations. 6. Velocity Sensor No maintenance required. Connect a manometer across the velocity sensor monitoring end connections, manually operate damper and observe changes in the readings to ensure the velocity sensor is not blocked (reading should be 0 Pa in fully closed position only). 7. Heating Elements (where applicable) Check operation and all connections are secure. Check for any signs of cable overheating, due to possibility of arching from loose terminations. 8. Heating Hot ater Coils (where applicable) No maintenance required. Check for water leaks
