The principle of air conditioning always comes down to the same:
Absorb energy in one place and release it in another place
Choosing the right capacity is mainly having an installer able to calculate the capacity needed. He will take into account the influences on the capacity need like solar infiltration, lighting, number of occupants, the usage of room(s) in question etc.

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. 
 

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 take 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 thought 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.

 
Air conditioning is the process of treating the temperature, humidity, cleanness and distribution of the air.
  • Cooling
    Air conditioners offer precise temperature control. You can always create the climate in which you feel best, with the right temperature. Not only does it create comfort, it makes you feel fresh and active even in the most extreme outside conditions.

  • Heating
    Air conditioners can also offer heating. You can enjoy the perfect constant temperature all year through, no matter what are the outside conditions. It is an environmentally friendly alternative to traditional heating because it takes energy from the outside air and brings it inside.

  • Cleaning
    Properly maintained Air Conditioners should produce clean, healthy air. All indoor units should be equipped with filters that take dust, pollen, smoke etc from the air. According to the needs of the customer the level of filtration can be increased. Filtration is critical for persons with allergies.

  • Dehumidifying
    In cooling mode an air conditioner dehumidifies the air, creating a better feeling of wellbeing. Bear also in mind that a correct humidity level limits the growth of dust mites and molds, which again has a positive effect on persons with allergies. Human beings feel that 40 to 60 % is a comfort level of humidity. Also a correct humidity level ensures a longer lifetime of your appliances and house.  

  • Ventilating
    Ventilation can be integrated in the air conditioning system. It takes out the inside air and pushes in fresh, conditioned air from outside. In mid season, when the air conditioning is turned off, the ventilation can work independently. Our ventilation systems can also be installed without the air conditioning installation.
 
CAPACITY NEEDED:
By properly sizing HVAC equipment rather than using rules of thumb, smaller systems can often be specified and, hence, initial cost is reduced. Proper HVAC sizing is an essential step in the efficient operation of HVAC systems. A right-sized system will operate for long periods of time (rather than frequently cycling on and off), resulting in the optimum equipment operating efficiency.
