To determine the length of the battery, you need to find out what conditions are paramount for a certain room. In any circumstances, the calculation of the number of sections of heating radiators is made personally and will depend on:
The volume of the room. The height of the ceilings plays the main role.
The area of the room at the usual height.
A more detailed calculation is made, given the unification of the first 2 points.
Calculation of calculation needs to know what heat output 1 part. All normative signs of heat are taken into account in SNiP, for example:
The type of structure
Heat consumption for 1m3
Panel houses
41
The current structure with insulated double -glazed windows and walls
34
Example: room “5-10 m, area S = 50m2.Ceiling height “3 m, room volume V = 50-3 = 150m3.The house is panel, we calculate the desired power: 150-41 = 6150W. Cast iron radiators, heat return 1 part = 140 watts.6150: 140 = 43.9, which means that for the dwelling you will need 44 cast -iron parts. Basically, manufacturers overst the heat of the heat of radiators, and therefore should take a stock +20.For ordinary ceiling height, the number of radiators is considered to be the area of the room. In such conditions, the average feature “Distance of heat 1 part = 100W is accepted. Example: S rooms = 50m2 x 100 (average feature): 140W (nominal sign of heat transfer of the battery) = 35.7 = 36 sections.
How to definitely calculate the number of sections:
For a more specific calculation of sections, you need to know a lot of signs than the area or volume of the room. The power of the battery is considered according to the formula: Q = 100W/m2 x d1 x D2 x D3 x D4 x D5 xD6 x D7
