ZERO DEGREES (WORKING OF AN AIRCONDITION) ...

WORKING
When the temperature outside begins to climb, many people seek the cool comfort of indoor air conditioning. Like water towers and power lines, air conditioners are one of those things that we see every day but seldom pay much attention to.

Wouldn't it be nice to know how these indispensable machines work their magic?

Air conditioners come in various sizes, cooling capacities and prices. One type that we see all the time is the window air conditioner, an easy and economical way to cool a small area: The principle of air conditioning always comes down to the same:

absorb energy in one place and release it in another place

The process requires an indoor unit, an outdoor unit and copper piping to connect both. Through the piping the refrigerant flows from one unit to another. It is the refrigerant that absorbs the energy in one unit and releases it in the other.

The very basics of air conditioningCooling mode 1 Indoor unit A fan blows the hot indoor air over a heat exchanging coil through which cold refrigerant flows. The cold refrigerant absorbs the heat from the air and cooled air is blown into the room.

2 Copper piping The refrigerant circulates through the units and the piping and takes the heat from the indoor unit to the outdoor unit.

3 Outdoor unit Through compression, the refrigerant gas is heated and its boiling point increases. In the outdoor unit the obtained heat throught compression is released to the outdoor air by means of a fan which blows the outdoor air over a heat exchanging coil.

4 Refrigerant The liquid refrigerant flows back to the indoor unit.

5 Indoor unit Back in the indoor unit, the refrigerant is decompressed and thus enabled to extract heat form the indoor air.

SELECTING THE RIGHT EQUIPMENT
Creating the right climate is a complex matter. Several factors determine which equipment is the best solution for you. Be sure to be guided by an installer. Here are already some things to keep in mind.

To what extent do you want to control the indoor climate? Do you want cooling only? Or do you also want ventilation and/or heating? The choice will determine the type of system.

How many rooms? The number of rooms will determine the system. In case of more than one room it is possible to connect several indoor units to one outdoor unit.

Which kind of room(s)? A shop? An office? A bedroom or living room? Each application requires its own system.

Capacity? A system with too high capacity will lead to draught, fluctuating temperatures and high energy bills. With a too low capacity you will never reach the desired temperature. Choosing the right capacity is mainly having an installer calculate the capacity need. He will take into account the influences on the capacity need like solar infiltration, lighting, number of occupants, etc.

Place of the outdoor unit? Outdoor installationThe outdoor unit should get an appropriate place, on a solid base and accessible for maintenance.

Place of the indoor unit? The choice of the model will be determined by the possibilities to place the unit. Is there a false ceiling? Is there free space on the wall? Etc. Also the location of the unit is of great importance. Each unit has its own air distribution pattern. A wrong location may lead to draught and sound.

Weather durability? Mind the weather durability of the outdoor unit. This will determine the lifetime of the installation.

Air purification? The dust particles floating in the air can be removed by means of filters in the indoor units. Depending on the level of filtration we offer different filters.

Selection of the installer? The most important is to be advised by a good installer. He will calculate, draw up and install the required system according to your needs. His skilled advice and craftsmanship will ensure you of a good climate. Find your local installer by selecting your region:
