As summer beckons, it is time to consider a cooling solution that is not only affordable, but is also effective. There are a lot of variations between air conditioners when it comes to the features that they offer. This guide will serve to clarify a few of those, and inform users on what to look for when buying an air conditioner.
Kinds of air conditioners:
Air conditioners come in different variations to suit different needs. Let’s take a look at a few kinds of ACs that are available in the market:
- Window air conditioners: These ACs are economical, can be fitted into windows and are easily serviceable. They do tend to be a little noisy, however.
- Split air conditioners (without inverter): Split ACs run quietly, look sleek, and are mounted on walls. They use a single speed compressor motor which only has two modes, on and off. As soon as a desired temperature has been reached, the compressor switches off, and when it rises to a certain extent, the compressor starts cooling the room again.
- Split air conditioners (with inverter): These are similar to split ACs, but come with an inverter in-built. These ACs come with a variable speed compressor motor, which can adjust temperature dynamically without the need to switch off and on continuously. These ACs have been claimed to be 30% more energy efficient than split ACs without inverters. The image below gives an indication to how these mechanisms work.
Let’s see a few criterions on how various air conditioners are categorized.
