AC Basic Science

The general term that is when we discuss the AC is PK. Perhaps understanding the PK itself is still unknown to many people. PK is an abbreviation of Paard Kracht. These are the resources needed to produce a BTU (British Thermal Unit). BTU is what determines the resulting level of cool air. Indeed, to produce a large BTU require large PK anyway. That is why the degree of cold produced by the air conditioner is often determined based on its PK. 
How to determine the appropriate PK for our room? To answer that, we can use the following formula: 
Length of room (m) x Width of room (m) x Height indoor / 3 (m) x 500 

Then match the following divisions: 
Choosing PK AC 
PK results 
5000 ½ 
7000 ¾ 
9000 1 
12000 1 ½ 
example: 
The room-sized rooms 6 m long, 3 wide and 3 m high standards. So the results perkalianya be 5 x 3 x 3/3 x 500 = 7500 Then after matching with the table above, the number is between 7000 and 9000, so it can be used with AC or 1 ¾ PK PK. 
As a suggestion, you should use AC 1 PK sized so that air conditioning is not working too hard, because when used AC ¾ PK, means the air conditioner must work harder in order to adjust the size of the room. 
In order AC provide maximum results in providing fresh air following a few tips that can be done: 
• Adjust the size of the room with air-conditioning capacity. 
• Do not put right in front of the door, because the air will be easier to get out into another room. 
• Do not place the air conditioner is too close to the roof. AC took the air out of the top, then when it gets too close to the ceiling, narrow space causes the incoming air is not maximal. 
• Wash the filter once a month AC 1. 
• Perform laundering AC evaporator 3 months.
