When choosing the capacity of the air conditioner, the area of the room must be taken into account. This indicator is also influenced by the degree of sunlight penetration, the size of the windows, the number of people and appliances. If these are not taken into account, indoor air conditioning will be ineffective. The action of too weak equipment at maximum loads will not be noticeable, the device will burn out faster. Choosing too powerful a device is also not advisable. The number of on-off cycles increases, which leads to rapid wear of the equipment.
Ideally, the choice of air conditioner from the area of the room should be carried out by a specialist. You can try to do this using an online calculator or using such formulas.
Fast way of calculating
Each room has its own air conditioner With ceilings up to three meters, one hundred watts of power should be calculated per square meter of area;
- Add one hundred watts per person in the room;
- Add three hundred watts for each stationary computer;
- Indoor air conditioning, in which TVs, printers and any other equipment are located, requires adding another 1/2 of the power of each device;
- If the room is often entered or windows are opened, another 25% is added to the resulting figure;
- Air conditioning in rooms facing south or lavishly furnished with indoor flowers requires an additional 25%.
More accurate calculation by formulas
Suitable for the selection of an air conditioner from an area of a small room: living space or office no more than 70 square meters, located in houses with warm walls.
Q = Q1 + Q2 + Q3,
Here Q - the required power of the air conditioner in kilowatts.
Q1 - multiplying the area of the room by the height of the ceilings and the coefficient (35 W per cubic meter).
The coefficient can be 30 if little sunlight enters the room or 40 if the windows face south. When calculating the capacity of a future air conditioner, it is imperative to know the area of the room.
Q2 - the amount of heat generated by people. One adult identifies:
- 0.1 kilowatts while reading or watching TV, sleeping;
- 0.13 kilowatts when working on a computer, washing dishes or cleaning an apartment;
- 0.2 kilowatts for hard work or sports.
Q3 - the amount of heat generated by the equipment.
- 0.2 kilowatts - TV;
- 0.3 kilowatts - desktop computer;
- The rest of the equipment generates 30 percent of the maximum power of the device.
To ensure effective indoor air conditioning, it is allowed to select an air conditioner that is less than 5 percent of the calculated figure or exceeds it by 15 percent.
