PK stands for Paard Kracht. Normal AC capacity is assessed from how many PK AC’s. This is often also referred to as horsepower or power from the AC. In the meantime, check out the excellent aircon singapore service center near your area as well.
The formula for calculating the required PK
Use the formula below to calculate what AC capacity is needed.
= Room Size in m2 x 500
= Width x Length x 500
This calculation assumes that the height of the room you want to install AC is the standard height in the country, which is generally 2.50 – 3 meters.
The calculation above also does not take into account if for a room with lots of people or rooms that often open and close windows or open spaces.
The above formula will produce numbers in Btu units. This number needs to be matched with the ability of the AC to cool the room in a Btu / h unit that is common in every air conditioner. Laypeople use PK units in determining AC so that a chart is displayed here to help you convert how many PKs you need.
1 / 2PK = 5000 Btu / h (room size 10m2)
3 / 4PK = 7000 Btu / h (room size 14m2)
1KK = 9000 Btu / h (room size 18m2)
1 1 / 2PK = 12000 Btu / h (room size 24m2)
2PK = 18000 Btu / h (room size 36m2)
The size of my room is 20m2 and uses AC 3/4 PK. The Results Are Also Cold, Is It Not Wrong To Calculate?
The air conditioner is designed to cool the room. The benchmark number above is the capacity of the air conditioner to cool the room in a matter of 1 hour. So for a bigger room, it will still be cool and cool but it will take longer and consume more electricity than it should.
Conversely, if you use 1 pk AC in a 10m2 room, the AC will still work and the room will be cooler. But the electricity used will be too much so it is not efficient.
What if your room is larger than 1 AC capacity
As an illustration, if you have a room of 50m2 we recommend that you use 2 x AC 1 1/2 PK to cool your room.
