What is the best portable air conditioning unit in the UK? Portable Air Conditioning Buying Guide 2019

The two weeks of UK summer have officially landed in the
north, and like many, I can’t sleep. 30-degrees is bad enough in Blackpool, but
the heat is set to hit record levels in some parts of the country this week.

So inevitably, like each year, I have been on a quest for
the best portable air conditioner, which I end up not buying. This post aims to
put my findings in one place, and hopefully motivate me to commit to the expense.

There are a few issues with portable air conditioning units,
there are different types of air-con, the more effective type is very
expensive, and reviews of all the units tends to be mixed, they are also
expensive to run.

The different types of portable air conditioner – evaporative, single hose,
dual hose

If you go on Amazon, you will see a significant disparity between the prices some cost as low as £25 while many others cost £300+. The cheaper ones use evaporative cooling, so the fan blows warm air over a  water-soaked filter which increases humidity, produces condensation and only slightly reduces the heat. Increased humidity is often associated with poor sleep as it reduces your bodies ability to evaporate sweat.

The expensive models are more effective but this is a minefield.
Nearly all UK air conditioners are single host units which require you to feed
the hose outside.



The single hose air conditioner pulls warm air from the
room, sends it past coils cooled by refrigerant, and then sends heated air and
moisture through the hose and out of the house.

This creates a negative air pressure situation as air is
pushed out of the room. The result is that any cracks around doors and windows
will allow hot outside air to leak into the room

The other type of portable air conditioning unit is the dual
hose unit. This model has an intake and an outtake hose. Through the intake, the
air is drawn into the unit where it is cooled and then sent back into the living
area. The machine heats up through the process and an intake hose pulls air
from outside the home to cool the air conditioner down.

A second hose sends all of the warmed air outside of the
home. With this efficient exchange of air, the dual hose system doesn’t have to
work nearly as hard as the single hose option.

Considerations for a single hose air con?

The single hose unit has some fundamental flaws that cause
it to drawback in hot air, so when you use one of these units some considerations
need to be taken into account.

As the unit pulls in the warm air from your room, it causes
negative pressure, drawing in more warm air from any window cracks or through
doors.

So with these units, if you want it to be effective, you
need to use a proper window seal, which you can buy quite cheaply online. You
will also need to keep the doors closed in your room.

Are they loud?

There is no way to sugar coat this, yes they are very loud. Typically, they run at around 38-48db in the quiet modes for some of the quieter models and up to 65dB at max. 49dB-54dB for general usage is quite common. To put that into perspective, a washing machine normally runs at about 55dB or it is like someone in the room talking or the noise of light traffic while you are on the street.

Buy the right size

You need to be careful of is to buy the proper size air con
for your room. Too small and it won’t be able to cool the air down fast enough for
it to make much or any difference.

They are typically measured in BTU or British thermal unit,
and due to the inefficiency of a single hose system, you are better off sizing
up if possible.

There are plenty of air-con calculators online and this is
the best place to start for a room of around 5m in length and 5m width you will
find the recommendation to be around 9000BTU

Power consumption: How much does it cost to run?

The last thing to worry about is how much do they actually
cost to run? Some more bad news I am afraid, they are quite expensive. It’s a bit
like an electric radiator but in reverse.

The higher the BTU, the higher the kW/h a 12000BTU air con which can cool a moderately large room will typically use around 1.35Kw per hour.

Based on the tariff rate from my current supplier, Bulb,
that works out at around 18p per hour to run.

So, what are some good Portable Air Conditioning Units to buy?

I am not just an Amazon affiliate shill, but due to these being
a bit hit or miss on how effective they will be or at least how good they are
for the money, anything I buy will be via Amazon on Prime, so I can return it
easily.

Filtering out the results down to 4 star and above leaves us some of the following options. I have included a few evaporative options, these will not be as effective, however, I appreciate most people don’t have £300+ just lying around (me included).

Out of the ones listed I would be inclined to go for the electriQ 9000 BTU for small rooms, or the AEG ChillFlex Pro 12k for medium rooms. You would also need the window seal for effective cooling.

The Princess 352101 is well-reviewed for an evaporative cooler and the 5L tank capacity should keep it running for quite a while.
