Portable air conditioners come in handy when there may be a problem fitting central air conditioning systems, because either they are not required or not feasible, on the other hand portable air conditioning units can be used in all areas in the home or office, as well as places like warehouses or garages, of course the biggest advantage is that they are in fact portable and can be easily transported to other places, and more importantly can function as heaters and humidifiers when required.

The common myth that air conditioners suck the warm air and bring in cool air is dispelled as air conditioners simply pump out the warm air, process it, and pump it back as cool air, in fact portable air conditioning works identical to that of a refrigerator, making use of evaporation of coolants to provide cooling.

Portable air conditioning units consist of a compressor, a thermostat, cooling coils, and insulation, the compression of refrigerants initially a cold gas, will form the hot refrigerant to flow through the insulation coils, the heat will dissipate while flowing, and condenses into liquid refrigerant, which evaporates when it passes through an expansion valve, the liquid refrigerant becomes cool again, and the cycle keeps on repeating, the cold gas is then made to pass through a set of several coils, all the heat is taken away from the gas by the coils, thus reducing the temperature of the room.

Portable air conditioning systems often used where spot cooling is required for large rooms, and some companies use these units to cool computer systems, also used very frequently in industry, to cool certain machinery.

Air conditioning is the process of making the air cooler or warmer inside the home, thus, either raising the temperature, lowering it or removing humidity in the home, portable air conditioners, are available in many models, and the energy rating of portable air conditioning units is measured in BTUs.

A spokesman for Climachill suppliers of portable air conditioners and air conditioning nationwide said we offer portable air conditioners in ranges from 9000 btus to a huge 18,000 btus in either cooling only, or cooling and heating mode, and the units come with the latest technological breakthrough for portable air conditioners, the Self Evaporative Water Recycling to the layman this means that the unit re-uses approximately 75% of the water it creates.
