Heattechnical calculation is necessary for determination of thickness of a wall of the building and thickness of heater for comfortable existence of people. It is carried out according to Construction Norms and Regulations 23-02-2003 "Thermal protection of the building".
Instruction
1. Define type of the building and choose the corresponding materials. It can be a house, the public building heated periodically or seasonally. Thanks to it, you will be able to save construction materials and to prevent the room from moistening, soaking and emergence of a mold.
2. Define a type of an enclosing structure, type on uniformity, the location of rather external environment. Provide the scheme of a protection of a design with the indication of all structural elements and materials with their characteristics.
3. Choose the area of construction and its climatic conditions. Proceeding from it, you decide on duration of the heating period, average temperature of external air, a zone by humidity of construction.
4. Define characteristics of construction materials and designs. It is density, specific heat, vapor permeability coefficient, specific heat, heatassimilation coefficient, thermal resistance of air layers.
5. Choose the constructive solution of enclosing structures. They have to have the necessary durability, rigidity, stability, durability. In multilayered structures of buildings from the warm party have layers of bigger heat conductivity and with a big resistance to a paropronitsaniye, than outer layers.
6. Remember that the settlement temperature difference between temperature of internal air and temperature of an internal enclosing structure should not exceed the normalized sizes.
7. Define gradusosutka of the heating period. Round the received value to whole. Determine heater thickness.
8. As a result you receive that condensation of water vapor on an internal surface of an enclosing structure is impossible, so the constructive decision conforms to requirements Construction Norms and Regulations 23-02-2003 "Thermal protection of the building".
