Narbonne V VT

Vertical design radiators - Narbonne V VT

Convectors Narbonne V VT are composed of several interconnected profiled steel heating elements of a rectangular cross section. Each convector has got two bottom connecting openings, each with external thread G ½”, enabling bottom connection. Four side openings with internal thread G ½” are normally designed for mounting the Danfoss thermostatic valve insert with pre-regulation, plus the air vent and closing plugs. Narbonne V VT convectors are equipped with two side covers, but no top masking grille. The heating profiles are mounted vertically, so that to retain the 2 mm-wide distancing between each two, necessary to compensate for the heat expansion of the elements, and enabling the perfect varnish cover of the entire convector’s surface. Most models are equipped with convective elements, increasing the heating efficiency of the convectors.

Hydraulic characteristics

The value of pressure drop in the radiator depends on the mass flow of water flowing through.:

Example of preset setpoint selection

Given:

heat demand - Qc = 1160 W 
rótemperature diff erence - Δt = 20 K (80/60°C) 
pressure drop - Δp = 6 kPa

Δp = 6000 Pa 
calculation constant - C = 1,163

calculations:

mass flow of water

q = Qc / C * Δt = 1160 / 1,163 * 20 = 50 kg/h

For the flow q = 50 kg/h and the pressure flow 6000 Pa the preset setpoint value 3 is red off the nomogram.
