How do I know how much HP my aircon needs?
Aircon capacity to room size guide To get a rough calculation, multiply your room size by 500. So if your room is 10 sqm. in size, you need an aircon with 5,000 kJ/hr of cooling capacity – which most 0.5 HP window type aircons have.
What size AC do I need calculator?
Room size
| Room size | Example | Approx. capacity |
|---|---|---|
| Small (up to 20m2) | Bedroom, study, small kitchen | 2–2.5kW |
| Medium (20–40m2) | Bedroom with ensuite, small lounge | 2.5–5kW |
| Large (40–60m2) | Large bedroom, mid-sized lounge, large kitchen | 4–6kW |
| Extra large (60+m2) | Open-plan areas, large lounges | 5–9kW |

How do I calculate aircon for a room?
To calculate a room’s area in square feet, simply multiply its length by its width. For instance, if the room is a rectangular 10 feet by 20 feet, the area would be 200 square feet. If the room is a perfectly-square 20 feet by 20 feet, the total area would be 400 square feet.
How do you calculate cooling requirements?
Take the total wattage of the lighting and multiply by 4.25. Add all the BTUs together. This is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.
How do you convert BTU to horsepower?
Converting BTU to Horsepower For example, the power of a boiler is often expressed in BTU, and car engines’ power is often expressed in horsepower. To convert BTU per hour to horsepower use the following equation: Power (Horsepower) = Power (BTU per hour) x 2,545.
How many Btus is 1hp aircon?
9,000 BTU/
When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.
How do you calculate hp motor without nameplate?
If there is no name plate, you won’t be able to know the rated voltage too. In that case, you may have to guess the approx. HP depending upon the size of the motor, select appropriate auto transformer and then run at no load by slowly increasing the voltage till it reaches steady state.
How is aircon load calculated?
Calculating a Home’s Cooling Load
- Determine the dimensions of the room or home that needs cooling. For a room, you can do this with a measuring tape.
- For a room, multiply its length by its width to get the square footage.
- Multiply the square footage by 20. This is the measure of the BTU cooling load of the space.
