Air Conditioning in Midlothian

Several individuals think that the the way their air conditioning system works is simply by pumping hot air out of their homes or offices, blowing a cool air in return. This is absolutely wrong! The hot air is, in fact, cycled back in as cold air and this process continues until the thermostats gets dropped down to the required or set temperature. The air conditioning system manages this in a similar way to how the refrigerator manages to stay cold and of course, excluding the insulated box.

The short and simple answer to the question of what gas an air conditioning use is Freon. This is a non inflammable gas which is subjected to the evaporation process over and over again in most refrigerators to keep the temperature at a low level. This same process is repeated in air conditioning systems. Now let’s take a look at how the Freon gas is incorporated in AC systems.

The cold Freon gas is firstly compressed by a compressor in the air conditioner. The gas is then combined with a little quantity of oil in order to lubricate the compressor. When Freon gas is compressed, the pressure is increased which makes it incredibly hot. It then moves through a couple of coils which works to lowering the heat and turning it to liquid. This Freon liquid will then be transmitted via an expansion valve which causes it to cool down until evaporation takes place. The outcome of this is a low pressure cold Freon gas which is then transmitted via another set of coils allowing the gas to collect the heat and lower the air within the room.

The air conditioner now filters the air and clears out the dust, smoke, pollen and other kinds of air pollutants. The system also absorbs excess liquid from the air too which it uses to cool down the system and pump it through a hose.

If you’re looking to purchase and install an air conditioning system in your home or property, what immediately comes to mind is the type to invest in. When it comes to air conditioners, the available choices are numerous - from window units to central air conditioning, through-the-wall air conditioners, portable air conditioners, ductless split system, package terminal air conditioners, swamp coolers as well as geothermal cooling systems. In this post, we’re going to consider the various type of air conditioners in order to help you make the best decision moving forward. Let’s take a look!

• Window air conditioners. These are the most popular type of air conditioners which are typically mounted in a window. They possess an exhaust system which pushes hot air out the back and sides while the refrigerant cooling is pointed indoors.
• Central air conditioning. This is the most effective form of air conditioning if you happen to own a large home and want all rooms cooled at once.
• Portable air conditioners. Just like window air conditioners, these are self-contained air conditioning systems. In other words, portable air conditioners have all their essential components in one appliance just like in window air conditioning units.
• Through-the-wall air conditioners. These self-contained units that operates by bringing in warm air which is then exhausted while they send cool air back into the room ( similar to window air conditioners).
• Ductless split system air conditioners. Just like the name suggests, these are two-part air conditioners that are able to cool various areas within a home.
• Package terminal air conditioners. These are the type of air conditioners that are mostly used for cooling in commercial spaces like hospitals, hotels and the likes.
• Evaporative or “swamp” coolers. Although these aren’t as common as refrigerant air conditioners but they are just as effective. While conventional air conditioners make use of a refrigerant known as Freon, swamp coolers only incorporates air and water to function.

If used and maintained properly, air conditioning can actually be a great way to create a healthier environment. As well as controlling the temperature, it also filters your air, removing pollutants like dust, pollen and mould particles.

However, to maximise these benefits, it’s important to keep your system clean. Dirty units and systems can become a health hazard, so always make sure you service your air conditioning at least once or twice a year.

NO - as air conditioning systems use fluorinated gases as refrigerants, all work on them must be done by professionals holding valid F-Gas certification. There is a range of different qualifications and certifications that apply for this, so it's always best to ask someone who is qualified to do this.
