A mobile air conditioning unit is a good investment for staying cool in hot summers, even if we live in the UK. It is portable, low-cost, easy to set up, and very energy efficient. A mobile AC unit, also known as a portable air conditioner, comes in various shapes and sizes, and the one you choose will depend on your cooling needs.

Whether you are looking for efficient cooling for your home, office, or conservatory, a mobile air conditioning unit can provide a much-needed breeze from the sweltering heat. Read on to discover useful tips for choosing the perfect portable air con unit tailored to your needs.

How a Mobile Air Conditioning Unit Works

A mobile air con unit works in the same way as a traditional AC. They do not produce cold air per se but draw in hot air and blow it out as cold air. Below is a breakdown of how that works.

A mobile air conditioning unit has four main components:

• The Fan
• Condenser Coil
• Compressor
• Refrigerant

The process begins with the compressor, which compresses the refrigerant gas, increasing its temperature. The hot gas then flows through a condenser coil, where it releases heat and transforms into a high-pressure liquid. This liquid passes through an expansion valve, causing it to expand and evaporate into a low-pressure gas.

As it evaporates, it absorbs heat from the air, thereby cooling it. The cool air is then blown back into the room, while the refrigerant returns to the compressor to repeat the cycle.

 

 

This continuous cycle of compression, condensation, expansion, and evaporation allows the mobile air conditioning unit to generate a stream of cool air, providing relief from the summer heat.

Note that portable air conditioners generate a lot of heat around the condenser coils. This is why a venting kit is fitted to direct excess heat away and prevent the unit from overheating.

Are mobile air conditioners any good?

There are numerous benefits to using a mobile air conditioning unit. They can be handy in small spaces or where noise levels are a concern. Here are some more reasons why you should choose a mobile aircon over a traditional AC.

Portability

Unlike traditional air con units that are fixed to a specific location, mobile AC units can be moved around, from room to room, and you can travel with them as well. This flexibility ensures that you can stay cool wherever you are, whether it is in your bedroom or caravan.

Easy installation

Mobile air conditioning units are incredibly easy to install. They typically come with a window installation kit that allows for hassle-free setup. You don't need to hire a professional or make any extensive modifications to your space. Simply follow the manufacturer's instructions, and you'll have a cool and comfortable environment in no time.

Energy efficiency

Thirdly, mobile aircon units are energy-efficient. They are designed to cool specific areas rather than the entire building, which helps reduce energy consumption. This not only benefits the environment but also saves you money on your electricity bills. Additionally, many mobile air conditioning units come with energy-saving features such as programmable timers and sleep modes, further optimising their energy efficiency.

Easy to maintain

Portable air conditioners are easy to maintain and some of the repair work can easily be done at home. Modern mobile aircon units feature removable filters that can be washed and fitted back in. This helps keep the AC clean and functioning optimally.

 

Also, it is easy to remove the mobile aircon's outer casing and clean the coils inside. When not in use, the portable air conditioner can be covered to prevent dust from getting in, ensuring it works efficiently next time you need it.

 

 

6 Factors to Consider When Choosing a Mobile Air Conditioning Unit

Choosing the right portable air conditioning unit requires careful consideration of several important factors that are tailored to your specific needs and space requirements.

1. Cooling Capacity (BTUs)

It is crucial to determine the appropriate cooling capacity for effective temperature control. The cooling capacity of an AC unit is measured in British Thermal Units, abbreviated as BTUs. A rule of thumb is to select a portable air conditioner with a cooling capacity that will suit the environment in which it will be used. For instance, a 9000 BTU portable air conditioner would be ideal for 20 m2, while a 7000 BTU portable AC would suit spaces of 10–15 m2 and below.

2. Noise Level

The noise level of a mobile AC unit can have a significant impact on comfort, especially if you plan to use it in quiet environments like bedrooms or offices. Look for mobile air con units that have decibel ratings as low as ≤65 dB, indicating quieter operation.

3. Energy Efficiency

Seek out portable air con units that have high Energy Efficiency Ratios (EER) or Seasonal Energy Efficiency Ratios (SEER) to decrease energy consumption and lower operational expenses in the long term. Appliances are rated from A to G on the EER rating scale, with A being the highest rating for efficiency.

4. Portability and Mobility

Assess the portability and mobility features of the AC unit, such as caster wheels or handles, which facilitate easy movement from one room to another. This flexibility can be particularly advantageous if you intend to use the unit in various locations within your home or office.

5. Installation Requirements

Consider the installation instructions of the portable AC unit. Some units may necessitate venting through a window or wall, while others are designed for simple setup without the need for permanent installation. Select a unit that aligns with your installation preferences and limitations.

6. Extra Features
