Features and advantages
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.
