Calculation of the area of the heat-releasing surface of the radiator of the heating system

To calculate and select the parameters of the radiator of the heating system, we use the formula

F • k • (Th – T_V) = α • V • (T_V – Tg),

where  

F - the area of a surface of the battery, m²;

V - the volume of the room, m³;

Th - temperature of the heat-carrier, ⁰С;

T_V - temperature in the room, ⁰С;

Tg - temperature outside of a room (external), ⁰С;

k - heat transfer coefficient through a wall, Watt/(m²•K);

α - coefficient of the heating characteristic of a building, 0.5...1.8 kWatt/(m³•K).
