Unlike other portable ac units that are evaporative, these units usually employ the refrigeration based technology to cool the designated area. Therefore, they must have an elaborate venting mechanism to keep them operational.
There are three main types of portable ac unit choices: the single hose, dual hose and split air conditioning unit.
When it comes to choosing the best portable air conditioner, dual hose ones cannot match the efficiency and benefits of split air conditioners.
A single hose air conditioner has one hose connected to its vent kit at the back. This single hose is responsible removing excess heat from the room in form of warm air.
The highest rated single hose portable ac is the SoleusAir 8,000 BTU Portable Air Conditioner, Evaporative Single Hose, # KY-80.
As a result of having only one hose, the unit is ideal for very small rooms. On the other hand, a dual hose AC has two hoses for expulsion of hot air and suction of cold one from outside. This makes it very effective for larger rooms.
The best portable air conditioner with dual hoses is the Whynter 14,000 BTU Dual Hose Portable Air Conditioner with Heater (ARC-14SH).
It can also cool down the designated room very fast because of its ability to expel air quickly while maintaining a constant pressure within the room through its ability to cycle a lot of air at once.
The third common portable air conditioner is the split AC. It features a stand-alone compressor and evaporator although detachable refrigerant pipes connect the two. It usually has a wall mounted indoor unit connected to the outdoor one that has to be placed on a balcony or any open area.
The best split ac unit on the market today is the Pioneer Ductless Mini Split Air Conditioner.
It is better than both the single and double hose alternatives in many ways.
First, it produces the least amount of noise compared to the two and does not require the owner to drain it. Second, this air is always running until the desired set temperature is achieved.
