About
A portable air cooler have always been a popular option for lots of people for the obvious reason that they can be easily moved around. They are perfectly suited to smaller environments such as a small room or office as it would take forever to cool down a very large room. One of the greatest advantages of portable air coolers is the fact that they can be taken with you if you are moving home or offices. This means that you are not going to waste any more money on another air cooler if you have to move to another location. A portable air cooler that you can roll from room to room might appeal to you if your window space is limited or if you live in a building where ordinary room air conditioners are forbidden.

How does a portable air cooler work?
An air conditioner cannot create cooling because it only relocates the heat. The heat is removed in two ways, as an actual temperature drop, and as water. The refrigerant pushes the heat outside where it is discharged while the water, called condensate is collected alone and pumped or drained away. After being installed properly, most air conditioners perform these operations mechanically. A portable air cooler must be vented and drained manually by its user but we must not forget that these types of coolers can be easily moved from a place to another.

Types of portable air coolers
There are two different types of portable air coolers. The portable evaporative air cooler uses water to relocate the heat. This type of portable air cooler is very effective in dry climates, as humidity is a product of the cooling cycle. This type of portable air cooler can frequently be found with a 12 volt adapter for cars or boats.
The other type of portable air cooler uses a refrigerant and is very much like the a standard air conditioner window unit, with the exception of that it usually comes on wheels and is made to operate on the room’s floor. They have to be plugged into a standard 120 volt power supply, and a vent must be installed through a near window. A condensate pan must also be dumped from time to time when in use.

About
When it comes to air conditioning systems we refer to machines which are used to cool off the air inside a home. Most work by evaporation, allowing a liquid to evaporate inside the house to absorb some of the heat and then take the gas outside to cool off. By using air conditioning systems we can control the temperature, humidity, air movement, air cleanliness and heat radiation sometimes to accomplish a fine thermal comfort. 

Types of air conditioning systems
As long as you can chose from a wide range of air conditioning systems it can be tricky to know where to start if you don’t know much about air conditioning systems and how air conditioning units work or what type of unit is suitable for your house, office or building.

Variable refrigerant flow air conditioning system (VRF)
Variable refrigerant flow air conditioning is just one of numerous types of air conditioning that you can get. These VRF air conditioning systems are made from more than one air handling units which are connected to a single external condensing unit. This allows the refrigerant flow to be varied by using either an inverter controlled variable speed compressor or multiple compressors of varying capacity. These work by responding to changes in the cooling or heating requirements inside the air conditioned area.
Variable refrigerant flow air conditioning systems are very popular because it is possible to mix a wide range of different models depending on the building construction type. For instance it is possible to have a mixture of wall and ceiling mounted units which mean that a smooth distribution of air throughout the house, office or building can be achieved.

Split air conditioning systems
A split air conditioning system is basically made of two parts. The first one is the main evaporator unit which is placed inside the building and the second one is an external condenser box which can either be hung on an exterior wall by brackets, it can stay on the ground or it can be placed on a plane roof.
Many people prefer split air conditioning systems because the condenser is placed outside the building and there will be no annoying sounds coming from the operation unit.
