The GEA SiCo floor convectors SBQ and SBI assure enhanced comfort

The GEA SiCo floor convectors SBQ and SBI offer energy-efficient and comfortable heating of offices, museums, public buildings, and salesrooms. The units are installed in raised floors, and are particularly effective for facilities with large-area glass façades.

The principle: temperature-controlled air is emitted upward from the floor convector, at an oblique angle in the direction of the windows. The warm or cold air therefore rises along the window front, in accordance with the Coandă effect. This phenomenon prevents descent of cold air in the winter, as well as heat accumulation on the inside of the façade during the summer. The air rising along the window is deflected inward at the ceiling, and flows throughout the room in the form of a recirculation zone. The effect: room air is uniformly temperature-controlled, and the low air velocity prevents draughts throughout areas occupied by persons. The principle of dry cooling (the feed temperature of the cold water is approx. 16°C) eliminates the need for condensation pans and pumps, and prevents any collection of moisture. Despite the main 230-volt power supply, 24-volt technology throughout the system assures great safety levels.
 

The combination of the two floor convector systems (left: SBI; right: SBQ) allows the user to successfully cope with the conditions in rooms with varying degrees of occupancy density, and with different supply-air requirements.

SBQ

When GEA development specialists designed the GEA SiCo floor convector SBQ for heating and cooling, their primary objectives were to achieve great room comfort as well as low consumption of resources. The SBQ operates with a 4-line system, and is highly effective for installation in conventional raised floors. With a depth of 345 mm and a length of 1,250 mm (the outer dimensions of the cover grill), the SBQ takes up little space and can also be inconspicuously integrated in the interior furnishings of buildings with large glazed areas. The cross-flow fan of the SBQ operates extremely quietly, with a total of 5 speeds. As a result, fast temperature-control of the rooms is no problem – for example, after a weekend. At its top fan speed, the SBQ passes up to 320 m³ of room air per hour over the heat exchangers. With cooling capacity of 460 W and heating output of 920 W per floor convector, these units offer enough capacity to provide pleasant temperature control of conventional offices, without further support (both of these capacity ratings are for operation with medium fan speed).

During cooling operations (see illustration), highly uniform temperature distribution, with low air velocities, is produced in a large zone occupied by persons.
