In the serious companies which are carrying out sales of conditioners it is obligatory to eat the expert making all calculations and making necessary recommendations. But if for any reasons you need to calculate independently the power of this equipment, use special receptions.
1. When calculating necessary power of the conditioner for your living space, consider the following factors: F1 – heat coming to the room from the sun or others – artificial luminous sources; F2 – heat generated by the people who are in this room; F3 – heat which arrives from heating; F4 – heat arriving from office equipment or household appliances.
2. It is possible to look at approximate values of heatreceipts from above-mentioned sources in tables on the website: http://www.ic21.ru/sov/vibor/
3. Summarize all values of each of factors among themselves to find peak value which the conditioner has to "extinguish". The formula will look so: By F = F1 + F2 + F3 + F4 Choose the conditioner power exceeding the received digit (F).
4. Look at approximate values of heatreceipts from above-mentioned sources in tables on one of the websites, the corresponding subject, for example: http://www.ic21.ru/sov/vibor/
5. For determination of necessary power of the conditioner it is possible to use the approximate data given below. When calculating it is necessary to consider what on cooling of 30 square meters of room space will be required to 1 kW of power of the conditioner. If the room has no door, then to its area add the area of the adjacent room.
6. In view of to what party there are windows of your room, on 1 sq.m of window consider the following values of receipt of solar heat: South: 0.2 kW; West: 0.35 kW; East: 0.12 kW; North: 0 kW.
7. Consider the fact that power on removal of all heatsurpluses from the working electrical equipment, as a rule, undertakes equal 300 W, from people – peak value - 350 W.
8. Make calculation of the required conditioner power as follows: the power considering room space + power, considering the area of window and part of the world + 300 W (0.3 kW) on electrical equipment + 150 - 350 W depending on the number of the people who are in the room.
9. For example, to calculate power Split system for the room of 28 sq.m and windows of 3.4 sq.m which face the west it is necessary: 1 + 3.4 × 0.35 + 0.6 = 2.8 kW. Means, the 3 kW conditioner will be suitable for this room.
