BTU to PK calculator to help you choose your AirCon capacity

As a field engineer, my team and I often experience problems in calculating AirCon capacity and run out of time to find the formula to manually calculate it in a hurry or in a position that is less conducive to browsing. From this experience, we finally made an ac calculator that all of you can use to simplify the calculation.

How to determine AirCon capacity ? What is BTU to PK?

Air Conditioner or what people usually call (AC or AirCon) is one of the electronic devices that have become common needs in the community, installed from simple buildings to industrial level buildings. AC technology was designed more sophisticated with more affordable prices. The most frequent question we hear from the installer or owner (user) of the air conditioner itself is how to choose the appropriate AirCon capacity and how to calculate BTU to PK?

Often found in projects or residences there are cases where the air conditioner installed is small or the air conditioner installed is large.

To be able to maintain the life of an air conditioner and achieve energy efficiency, it is very important to determine the right room cooling needs. The global standard used to measure this need is to use BTU per Hour (BTU/h) units, which are then converted into PK (Horsepower) units.

The first step, we must first calculate the BTU/h needs.

The most common and fairly accurate formula for non-commercial (standard Home/Office) use is the method of room Area x heat factor.

BTU/h = Length (m) x Width (m) x Heat Factor

Heat Load Factor can be seen from the following list:

• 500: for a regular bedroom (less activity, less electronics, no direct sun exposure).
• 600: for living room, family room, or bedroom with large windows (sun load).
• 750 - 1,000: for the kitchen (stove), office space (many computers), shop, or restaurant.

Case Examples:

We engpocket team want to install air conditioning in the customer's living room size 4 x 5 meters. How to calculate the BTU to PK of the AieCon needs?? Which capacity should we choose?

BTU = 4 x 5 x 600 = 12.000 BTU/h

The second step is to convert BTU/h to PK

Here is a conversion table of AirCon standards :
1/2 PK = ± 5,000 BTU/h
3/4 PK = ± 7,000 BTU/h
1 PK = ± 9,000 BTU/h
1.5 PK = ± 12,000 BTU/h
2 PK = ± 18,000 BTU/h
2.5 PK = ± 24,000 BTU/h

Then engpocket team should buy 1.5 PK Air Conditioner.
