Portable Air Conditioner: What is a Portable AC and how does it work?

For all practical purposes, a portable AC is much like a Window or Split AC, using an evaporator coil, condenser coil, compressor, and fan to cool the air. However, the form factor of a portable air conditioner is different, as it is a self-contained and entirely portable unit, unlike a window AC or split AC which needs to be mounted on a window or outside facing wall, and have the split unit separately installed in an outside area.

The way an air conditioner functions requires for warm air to be exhausted, and it’s no different with a portable AC. You’ll need to attach the included hose pipe to the rear of the portable AC, which will carry moisture and heat out of the room. You will therefore have to be careful with installation and setup, as you’ll need to have a way to channel the hose to dump heat and moisture outside.

Once properly set up, a portable AC can cool and recirculate cool air in the room the same as a window AC or Split AC and are generally as energy-efficient as well. This also includes the need for regular servicing, as well as periodically ensuring that the AC gas is topped up to ensure the appliance is able to continue cooling efficiently.

Despite the similarities in form and the ability to move the device around, a portable AC is different from an air cooler. The former functions the same as an AC and uses a complex process to more effectively cool air in a closed space without the need for water, while an air cooler uses large quantities of water for the cooling process, and works best with fresh air.

Depending on the design, a portable AC can either be light enough to lift and carry or can be rolled around from room to room on wheels. You can therefore use the same air conditioner in different rooms of your home as needed, thus saving on the cost of buying multiple air conditioners for different rooms, and the hassles of fixed installation that come with window or split ACs.

Another key advantage of owning a portable AC is the ease of setup and installation. Since the device is an independent unit, it simply needs to be plugged in to use, with the exhaust pipe channelled outside through a small gap or window.

This can come in handy in homes where installation is tricky, and some models are designed to be narrow and tower-like, thus being able to be positioned conveniently in the corner of a room. The vents can also thus be positioned closer and more conveniently towards the user, thus promising more effective and targeted cooling.
