Tips Knowing the capacity of the AC. What is the PK or BTU / h to be installed?

Tips Knowing the capacity of the AC. What is the PK or BTU/hr to be installed?

One of the things that often the question when we decided to use the air conditioner is how do I know PK room air conditioner that suits us? This needs to receive attention because of its relationship with the amount of power consumption we have to pay each month. Unit air conditioner that is too large compared to the space will make a wasteful use of electricity, as well as air conditioner units that are too small. Unit air conditioner that is too small compared to the area of ​​the room will take a long time to cool the room, it would also make a big electric bill.

There are three factors to consider when determining the needs of PK AC, the AC cooling power (BTU/hr - British Thermal Units per hour), power (watts), and PK AC compressor. Some of us may be more familiar with the numbers PK (Paard Kracht / Power Horse / Horse Power (HP)) on the AC. PK Actually it is a unit of power on the AC compressor cooling rather than AC power. But PK is better known than the
BTU/hr at the general public. Then how do I calculate and adjust the air conditioner with a cooling power of your room? To work around this, then we convert the first PK - BTU/hr - the area (m2).

1 PK = 9000-10000 BTU/hr
1 m2 = 600
BTU/hr
3 mx = 10 feet -> 1 meter = 3.33 feet

Cooling power based on PK:

± 5000 BTU / hr = ½ PK
± 7000 BTU / hr = ¾ PK
± 9000 BTU / hr = 1 PK
± 12,000 BTU / hr = 1 ½ PK
± 18 000 BTU / hr = 2 PK

To calculate the BTU requirement to use the formula:
(W x H x I x L x E) / 60 = BTU requirement

W = length of the space (in feet)
H = height of room (in feet)
I = value of 10 if the insulated space (located in the basement, or coincide with other rooms). Value of 18 if space is not insulated (upstairs).
L = width of space (in feet)
E = value of 16 if the longest wall facing north; value of 17 if facing east; value of 18 if facing south, and the value 20 if facing west.

example:
3mx6m sized space or (10 feet x 20 feet), height of the room 3m (10 feet) is not insulated, the long wall facing east. BTU requirement = (10 x 20 x 18 x 10 x 17) / 60 = 10,200 BTU AC alias enough with a PK.

In order for air conditioner provides maximum results in providing a fresh air here are some tips that can be done:

     Adjust the size of the room with a capacity of air conditioner.

     Do not be 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. Air conditioner draws air from above, then if it is too close to the ceiling, the narrow space causes the incoming air is not maximal.

     Wash air conditioner filters once a month.

Perform washing evaporator AC 3 months.

Becoming A Computer Technician – Tips On How To Get Started

 by: Jessica Lacy

If you have a natural affinity for computers, and you enjoy working with machines, then one of the most rewarding and enjoyable jobs that you might want to look at is that of becoming a computer technician.

Among the benefits of becoming a computer technician is that it is a very varied and interesting profession, in which you can choose from a number of different ways to progress, and also choose whether you would like to be self-employed and running your own business, or you can work for an employer and follow a more structured employment path.

One of the routes into the work of a computer technician in recent years has been to study a course in computer building or repair that will give you a good foundation of knowledge about how computers are constructed, and how the various parts within the computer work together and complement each other.

Another option if you have already been tinkering and upgrading your own computers for some time is to look for a local computer technician who should be fairly experienced, and is willing to take on an apprentice so that you can get plenty of practical experience, and then apply this experience under their supervision as you develop your computer knowledge.

If you prefer to work in an environment where there is a more structured progression and development in your role as a computer technician, then you may want to consider looking at corporations which have large offices in your area, as these will often have a number of IT staff already working there. Among the benefits of following this career path is that the company will often sponsor you or at least give you some support in earning more qualifications and accreditations to help you develop.

Once you have begun to be established as a computer technician, then it is valuable for you to think about getting more qualifications or accreditations, which will allow you to increase the breadth of your knowledge and experience, which will naturally assist you in getting more lucrative opportunities, and moving forwards in your career as a computer technician. These can be either educationally based, or be accreditations provided by manufacturers.

Whichever route you choose, becoming a computer technician can be both an interesting and lucrative profession.
