Function

Radiant panels use both radiant and convective heat transfer to heat or cool the space. Radiant heat transfer is approximately 55% and convective 45% with ceiling integrated radiant panels (Fig.1.) in typical cooling conditions. Radiant heat transfer is approximately 90% and convective 10% with ceiling integrated radiant panels (Fig.2) in typical heating conditions. 


Fig.1.  Cooling


Fig.2. Heating

Cooling and heating capacities are typically higher in exposed installation without top insulation compared to ceiling integrated installation.  Cooling or heating of the space above suspended ceiling can be reduced by using top insulation with the panel. Alternatively, panels without top insulation in suspended ceiling can be utilised to conduct cooling or heating capacity through the slab to the upper floor.

Effective panel area is the area of a radiant panel covered with heat exchanger piping. The cooling capacity of radiant panel is measured according the standard EN-14240. The standard describes the specification of cooling capacity measurement of the radiant panel in exposed and ceiling integrated installation.

The capacity of radiant panels is dependent on the ratio of effective panel area to the whole ceiling area. Decreasing the ratio increases the capacity of the effective panel area. Cooling capacity measurement according the standard EN-14240 requires the ratio being less than 50% in exposed installation. In ceiling integrated installation, the ratio shall be over 70%. The effect of the ratio is taken into account in Halton HIT Design’s performance tool. Also, both cases of the EN-14240 can be calculated with the tool.

The standardised measurement of heating capacity is done according to EN-14037, which includes five parts. The Declaration of Conformity (CE mark) for radiant panels is required for radiant panels used for heating. This includes measurement results for the CE mark according to the EN-14037-2 (part 2). This measurement is done in accredited laboratory for one and two loop AVP-3000-600 radiant panels in exposed installation and with top insulation. The measurement standard EN-14037-5 (part 5) contains also other standardised measurement of radiant panel heating capacity.     

Convective heat transfer and the total capacity of the radiant panel can be increased with air distribution. The total capacity will increase in the areas where supply air jets are flushing the radiant panel surface. Typically this can be approximately 5–10% in cooling conditions (with 16 °C supply air temperature) and 10–30% in heating conditions depending on the air distribution method and operating conditions. This effect is not included in Halton HIT Design, and should be analysed separately.

Installation

Halton Ava AVP radiant panels are suitable for exposed and ceiling integrated installation.


Adjustable installation brackets make installation easier.
Threaded rods and flexible hoses are not included in Halton Ava AVP delivery.

See locations of installation brackets in Dimensions tab .

Adjustment

Cooling

The recommended cooling water mass flow rate is 0.020-0.035 kg/s, resulting in a temperature rise of 1-3 °C in the heat exchanger. To avoid condensation, the recommended inlet water temperature of the heat exchanger is over 14 °C.   

Heating

The recommended heating water mass flow rate is 0.015-0.030 kg/s, resulting in a temperature drop of 3-10 °C in the heat exchanger. In typical rooms (room height up to 3 m), usual recommended maximum temperature of the inlet water is 50 °C due to the risk of too high radiation asymmetry. With exposed installation to minimum 3 m from floor and with effective panel area / whole ceiling area less than 50% also higher inlet water temperature (e.g. 60 °C) can be used without risk of too high radiant asymmetry.    

Servicing

Clean the front panel and other visible painted plates using a damp cloth.

Also top panel of exposed installed Halton Ava AVP panel can be easily cleaned with a vacuum cleaner or a damp cloth.

Specification

The radiant panel is 595 or 1195 mm wide and 9 or 16 mm thick.

The front panel, top panel and installation brackets are made of galvanised steel.
All visible parts are white, painted to RAL 9010, 20% gloss.

All pipes are manufactured from copper, and wall thickness of the pipes is 0.6 mm.
Maximum operation pressure for the pipework is 1.0 MPa.

Visible surfaces of the radiant panels are protected by removable plastic coating.
The pipe ends are sealed during delivery.
The radiant panels are identified by a label attached to the top side of the panel.
