If you wish to purchase and install the air conditioner to cool the air in the room is simply not enough to choose your favorite model. Previous How to determine the air-conditioned, you need to make calculations, To determine its capacity. Calculation of the power conditioner to cool the room, It will help determine the main parameters and functionality required air-conditioning.

To calculate the cooling capacity of the room quickly and easily, You can use the online calculator.

Calculation of the power conditioner is based on the formula:

**Q = Q _{1} + Q_{2} + Q_{3}**

Where,

**Q**heat inflow space;_{1}—**Q**Heat influx of people, inside the room;_{2}—**Q**heat inflow from computers, televisions and household appliances._{3}—

To calculate the ratio Q_{1} formula is used for the main parameters:

**Q _{1} = S · h · q / 1000**

Where,

- S - area of the room (m²);
- h - height of the room (m);
- q - room lighting ratio, equal 30 – 40 W / m³:

also on **Q _{1}** influenced by a number of additional parameters such as:

- Ventilation - increases the coefficient of base coefficient
**Q**from 10% and higher, depending on the multiplicity of ventilation_{1 } - Support temperature 20 ° C - increased required power for 20%;
- Floors - Top Floor, increasing base
**Q**on 15%;_{1} - glass area - depending on the area of the window depends on the power conditioner.

calculation coefficients **Q _{2} and Q_{3 }**simple enough:

- Q2 = the number of people in the room
**·****0,1 kW** - Q3 = Number of computers
**· 0,3 kW + Number of TVs · 0,2 kW + Power remaining devices · 0,3**
