Calculation of power conditioner

Approximate calculation of cooling power Q (in kilowatts) is made according to the standard technique:

Q = Q1 + Q2 + Q3, where Q1 - heat leakage from the window, walls, floor and ceiling.
Q1 = S * h * q / 1000, where

S is the area of ​​the room (m2);

h - room height (m);

q - coefficient equal to:

q = 30 for a shaded room;

q = 35 with medium illumination;

q = 40 for rooms in which a lot of sunlight falls.

If direct sunlight comes into the room, then there should be light curtains or blinds on the windows.

Q2 - the amount of heat gain from people.

Heat leaks from an adult:

0.1 kW - at rest;

0.13 kW - with easy movement;

0.2 kW - during exercise;

Q3 - the sum of heat gains from household appliances.

Heat leaks from household appliances:

0.3 kW - from the computer;

0.2 kW - from the TV;

For other devices, we can assume that they emit 30% of the maximum power consumption as heat (that is, it is assumed that the average power consumption is 30% of the maximum)

The power of the selected air conditioner should be in the range of -5% to + 15% of the calculated power Q.
