What is Air Conditioning ?

An air conditioning system is based on the precise control of not just temperature but also humidity, air flow and air cleanliness. The system needs to regulate these elements to provide you with a comfortable and relaxing atmosphere, Day and night, Year after year. With air conditioning you can create your perfect comfortable surroundings just by setting the right temperature.

Modern air conditioners produce clean and healthy air, all of this is achievable with neither draught nor noise. In short, air conditioning makes you feel better, more active and fit, resulting in many advantages, because (as they say) he who feels better is more creative and productive.

To sum up who doesn't like to be in a shop, café, restaurant or hotel with air conditioning, not just in the summer when you crave that cooling but also now with the introduction of heat pumps built in to every unit you now benefit from that all important ultra cheap heat that we unfortunately need in this country during those bleak winter months.

What is Cooling Mode ?

Energy is absorbed from one area and release into another
The process requires an indoor unit, an outdoor unit (the pump) and 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. 
Cooling mode 

1 Indoor unit (evaporator)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 pipe workThe refrigerant circulates through the units and the piping, taking the heat from the indoor unit to the outdoor unit.

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

4 RefrigerantThe liquid refrigerant flows back to the indoor unit.

5 Indoor unitBack in the indoor unit, the refrigerant is decompressed through a expansion device and thus enabled to extract heat form the indoor air.

How about Heating Mode ?

Heat pumps systems are air conditioners which can be used both for cooling and heating. The principle is that it is able to reverse the process of transporting heat from one place to another.

Energy efficiency? Heat pumps are much more energy efficient than other heaters. The reason for this is simple: rather than burning a fuel, what it does is 'moving heat'. Because of this heat pumps are up to five times more energy efficient than other heaters.

Heat pumps additionally allow the refrigerant cycle to be reversed.  A heat pump extracts energy from the outdoor and transfers the free heat indoors.  This principle even continues to function on very cold days with temperatures down to -5°C, -10°C or -15°C, depending on the type of air conditioning system used.

Therefore, heat pumps eliminate the need for a heating system and allow you to cool and heat with the same unit, with savings in costs and energy throughout the year.

What types of Unit are there ?

What are the pros/cons of multi-split systems

Only 1 external compressor
Ideal for domestic & small offices with limited external space

Can only be used on all units heating or all units cooling so not ideal for large offices
In the unlikely event of external condenser break down all units suffer

Do the units come with remote controls ?

The units come with easy to use remote controls

What about the installation ?

A normal wall mounted back to back installation (that is internal unit fitted to external wall with the external condenser directly adjacent on the external wall) will only take around 4 hours with the internal work taking no more than 2 of them.(ceiling cassettes take 8 hours total)

If there is no external wall for the internal unit to be installed on then installation can take up to 8 hours depending on length if pipe run to connect internal unit to external condenser. If this happens the time is taken up by fitting a decorative trunking to the wall from the internal unit to the nearest external wall, this can be painted at a later date to mach decor.

Sometimes the external condenser has to be installed at low or high level in comparison with where the hole is drilled for the pipe work and interconnecting wires to exit the building, then in this circumstance we also install trunking on the exterior of the building to hide pipe work and wires.

The only other disruption may be if you choose to install your own electrical supply (this is optional for EDS or customers) in this case all requirements will be told to your electrician prior to our arrival, if its not possible to install supply EDS can test and commission using temp supply and your electrician can install at a later date.
