Air Conditioner Inside The Room

Benefits Of Air Conditioning

Along with their primary role of keeping the air inside a room at a comfortable temperature, air conditioning systems have several other benefits such as reducing humidity, improving air quality and eliminating odours.

This not only results in a much more comfortable living or working environment, but also helps to create a healthier home or office. Mould growth is limited, odours are dissipated quickly and humidity levels are kept comfortable.

Air Conditioning Installation Process

The actual installation process will depend on the type of air conditioning unit you install, but we’ll focus on split and mini-split systems here because these are the most common for home and mid-size offices and industrial units.

First, the indoor evaporator and heat exchanger units are installed. There is typically one unit for each room. Next, the outdoor condensing unit is fitted in a secure area close to the building. A network of pipes is then installed to connect the indoor units to the outdoor condenser. Once finished, the entire system is tested and commissioned.

While the above process appears pretty simple, there are lots of things to think about when designing an effective air conditioning system. That’s why we always recommend business customers consult with an air conditioning engineer before committing to a specific system.

Frequently Asked Questions

The main difference is the output of the systems. A typical residential system will consist of five indoor evaporators connected to a single 5000 kW condenser, while a commercial system may consist of 20 or more evaporators connected to three or more 10,000 kW condensers. Commercial systems can also be designed for more specific purposes such as creating a cool room for perishable foods or pharmaceuticals.

There are several types of air conditioning systems, including ducted, split and window-mounted systems. For most small homes and apartments, a mini-split or window-mounted system should provide all the necessary cooling output.

Mid-size homes and small/mid-size offices, meanwhile, should go for a split system, with multiple evaporators connected to one or more condensers. For large office buildings, schools and hospitals, a ducted system will be the most cost-effective.

When designing your air conditioning system, the engineer will take into account several variables such as the size of the room, the number of people living or working there and the expected high temperature during the year.

But as a rough guide, you should allow 125 watts per square metre, so a 500 sq m office will require an air conditioning unit with a minimum of 6250 kW output.

There are several signs your air conditioner needs servicing. The most obvious is that it struggles to keep the temperature inside the room at the required level. Bad smells emitting from the evaporator unit are also a sign your unit needs servicing. Other things to look for include refrigerant leaks, condensation on windows and rattling noises from the condenser.
