# HOW TO CALCULATE COOLING CAPACITY OF AIR CONDITIONER UNIT

There are several factors that should always be considered when you want to calculate the cooling capacity of air conditioner.

## Living quarters and rooms

Household air conditioners will be quite enough for cooling of a ordinary apartments. If the building is an apartment but with many rooms then it is advisable to choose the multi split-system that provides installation of one outer block and several inner blocks. The internal blocks can work individually for each room’s air conditioning settings.

## Large commercial buildings

Huge commercial areas (e.g. gyms, supermarkets, etc.) require semi-industrial and industrial air conditioners. which not only good for humans but also for machinery.

## What you need to know before CALCULATion

When calculating the air conditioner cooling capacity, you have to calculate the area and height of the room. It is said by a specialists that to cool the area of 10 sq. m. you need a air conditioner with minimum cooling capacity of 1 kW. This value is optimal when calculating if the height of the ceilings is not more than 3 meters. It is also necessary to calculate the number of windows, their area and location. If the windows face the south and ingress heat influx in room, then the calculated capacity of the air conditioner should be increased approximately by 20 per cent.

you have to take all factors in mind while calculating air conditioner cooling capacity, it directly effects the cooling of your air conditioner. There are some other factors which can also effect the cooling such as the number of people in the premise, the number and characteristics of household appliances.

## HOW TO CALCULATE COOLING CAPACITY OF AIR CONDITIONER.

Calculation of the air conditioning system is very easy Everyone can calculate the required capacity of the air conditioner by himself, using a simple formula. First of all, you need to know heat gaining areas of room. To calculate them, the volume of the room should be multiplied by the heat transfer coefficient. The value of this coefficient is in the range from 35 to 40 W and depends on the orientation of window openings.

Further it is necessary to determine what heat energy is emitted by household appliances and energy of people who will constantly be in the room. All these values of heat inflows we sum up. We increase the found number by 15-20% and we receive the necessary power for cooling the air conditioner system.

EASYWAY OF CALCULATE CAPACITY OF AIR CONDITIONER.

The second way is very easy

• if you want to calculate the cooling capacity of a room then, multiply its length by its width to get the square foot area.
• Multiply the square foot area by 20. This is the measure of the cooling load of the space.
