How air conditioning works Nueva Andalucia, Puerto Banus, Marella and along the Costa del Sol

Air conditioning systems work by moving heat from inside your property to the outside. In a central air conditioning system air is drawn into the duct work through the return air con system. Installed in the return air ductwork is an evaporator coil. This coil is connected to the condensor, the unit that is outside your home, connected by copper tubing.

The refrigerant is then pumped from the condenser to the evaporator coil. As the refrigerant passes through the inside of the evaporator coil warm air from inside your home passes over the outside of the coil. Because the refrigerant is changed from a liquid to a gas, it is cooler than the warm air, the refrigerant absorbs heat from the air. The refrigerant is then sent outside to the condenser unit. When the warmed refrigerant in the condenser unit is compressed by the compressor, the compression of the refrigerant causes it to boil. As the refrigerant boils it gives off the heat it picked up from inside your home. The refrigerant is then passed through the coil in the condenser unit where it gets cooled again and is ready to go back inside to pick up more heat from your home As this whole process is going on, the temperature and relative humidity in your premises are both lowered. The relative humidity level drops because cooler air can not hold as much moisture. As the air cools it gives up some moisture and it gets collected in the base of the evaporator coil and is then drained away. The styles of indoor unit that we can fit are listed below:

How much does cost to run a airconditioning system

Air conditioning units transfer heat between the two units and you pay for the electricity used to do this. Typical values in cooling for the coefficient of performance (COP) are around 2,5 to 1 which means you can transfer 2,5 kilowatts of heat for 1 kilowatt of electricity. In heating the typical coefficient of performance (COP) values could be 3 to 1 or more.(electricity is around 10,5 cents per kilowatt).

WALL MOUNTED This unit is often used in residential properties. The wall unit is the quickest to install and the cheapest to buy. So ultimately that means the lowest installed price. The unit is hung on a wall above head height and blows hot or cold air into the room.

FLOOR This unit is used when there is no ceiling void or no wall space. It is slighly more expensive to buy than a wall unit and takes about as long to install. It is a little like a radiator except it blows hot or cold air rather than using water.

CASSETTE This unit is often used in offices or retail outlets. The cassette unit is fixed from the roof above a ceiling void and the white four way fascia is the only part of the unit you see. It takes longer to install this unit than a wall mounted unit and is more expensive to buy but it distributes the air in four directions so gives better coverage and a more gentle air flow.

DUCTED This unit is the `creme de la creme´of air conditioning! It is, of course the most expensive to buy and install but it means the customer sees nothing other than inconspicuous air diffusers in the ceiling. The unit is mounted as a cassette above a ceiling and ductwork is intalled to carry the air to the diffusers. This gives a very comfortable environment and good coverage. The good thing about air conditioning is its flexibility. You can run any of the above from one outdoor condensing unit which is called a single split. Or you can run a number of indoor units from the outdoor unit, this is called a multi split. You can even run up to 32 indoor units from one outdoor unit if the need arises, like a hotel application VRF, variable refrigerant flow.

So there is not many applications that can´t be heated or cooled by air conditioning. The vital part of any installation is to consider these points:

Once these points are established a budget price can be confirmed. Clearly therefore other factors that determine the design of the installation, but these are the basic points.
