HYBRID Terminal Air treatment 36XB Options Communicating controller • BMS compatible controller • For 2 pipe, 2 pipe + electric heater and 4 pipe applications • Aquasmart Evolution System compatible • Variable fan speed control, demand based ventilation (CO2 monitoring) and coil condensation control. • Integrated window blind and lighting control. • Motorised blinds & lighting control Aquasmart New System Manager Features • The 36XB Hybrid Terminal combines the advantages of both chilled beams and fan coils: energy efficiency, high levels of comfort, extremely low noise and high indoor air quality. • The low height profile (<200mm) of the unit facilitates installation in low height ceilings and allows increased room heights for refurbishment projects. • Unit aesthetics can be tailored to suit site specific ceiling layouts, colour schemes and return air grill design. • Unlike conventional chilled beams, the Carrier 36XB Hybrid terminal is fitted with a coil condensate drain pan as standard. Even if the cooling coil is supplied with chilled water at 6°C, there is no danger of condensate falling into the occupied space. • A unit mounted changeover valve allows the coil to be connected to a 4 pipe water system so providing either cooling or heating, as required. • If required, the Carrier 36XB Hybrid Terminal can be fitted with a room air return filter G3 to F5. This filter is accessible for cleaning / replacement without disturbing the unit / ceiling. Principals of Operation • Primary ventilation air is supplied to each unit inducing secondary (room) air flow over the cooling / heating coil without the need to run the unit fan. • During periods of peak demand, the unit fan may be energised to increase secondary air flow hence and boosting the unit cooling / heating output. • Unique Carrier supply air diffuser design ensures excellent air distribution, no ‘dumping’ and minimal room temperature gradients in both cooling and heating. • The primary ventilation air volume can be controlled based on room CO2 levels to maximise comfort and minimise system energy consumption • The CO2 sensor (optional) mounted in the secondary (room) air flow can modulate the supply of primary ventilation air to the unit from 2.8 to 33 l/s, depending on room occupancy. • Using the unit fan only when there is a peak demand in the occupied space offers energy savings for up to 80% of the annual building occupancy. • Based on a typical office profile & loads this economy can result in an average annual unit specific fan power (A-SFP) <0.05 W/l/s • Assured air quality; in addition to varying the quantity of hygienic air, the hybrid terminal 36XB may receive a filter on the return air available from the grid. • Energy efficiency, easy installation, comfort, low noise and high indoor air quality. 102
