It is the most widespread system at present and thanks to it an important energy saving of up to 70% is achieved.
Unlike the “Inverter” system, these units use 100% of their power to reach the indicated temperature, which translates into higher energy consumption, which is reflected in the monthly electricity bill.
Type of refrigerant gas
When installing an air conditioning system it is interesting to know which refrigerant gas it uses, since not all air conditioning systems are the same in this respect. Choosing one or the other can, on the one hand, help to be respectful of the environment and, on the other, lighten our electricity consumption.
It is to date the gas that has been used to run air conditioning systems. Less polluting than the previous gas, R22, is increasingly being displaced by other options.
The newest is R32 gas, a more environmentally friendly refrigerant gas, which requires less gas charge than an R410A system and is also more efficient. It’s getting more and more used.
Before choosing an air-conditioning model, we must consider what cooling capacity we need. These are the famous frigories and we can calculate them by measuring the square metres of the room to be air-conditioned and then multiply this figure by 100 or 140 frigories, depending on how cold or warm our house is.
It is a fundamental factor when it comes to choosing one or the other device. We must look for an efficient air-conditioning system. The easiest way to do this is to check the energy label on the box and find one of these possible categories: A+, A+++ and A++++.
Class A: You hardly see them on the market anymore.
Class A+: consumes up to 10% less fuel than a class A car.
Class A+++: consumes up to 16% less fuel than a Class A car.
Class A++++: it can consume up to 40% less than class A.
Noise is another level to study. With respect to the indoor unit, a maximum of 24 dB is advisable, while the noise level in the compressor unit (outdoor) may vary depending on the type of building or community in which we are living, generally a maximum of 45 dB.
Use of filters
We’ve already seen the importance of filters in air conditioning and how to keep them clean and in good condition. They are barriers that eliminate the entry of dust, smoke and other harmful elements that can harm our health and that, if they accumulate, can obstruct the air conditioning’s operating ducts.
There are many types of filters and some are even washable, so we don’t need to change them. Thus we have the photocatalytic type that are cleaned with sunlight. The plasma or neoplasm ones, indicated for allergic and asthmatic people and that are able to purify and deodorize the air. There are also active carbon filters, designed to absorb odours or tobacco smoke. There are even filters that seek to improve air quality, such as those that emit negative ions to balance the excess of positive ions, which are those emitted by electrical appliances.
Is it interesting to opt for “intelligent” air conditioning?
Little by little, the concept of the “intelligent” home, or rather, the connected home, is spreading. Even the kitchen, that traditionally isolated niche, has been conquered by permanently connected devices.
It is more correct to talk about connected appliances than about “intelligent” ones, which ultimately seems more like a marketing operation to sell more by the different companies. Intelligent they are not, they do not perform any function on their own and only when they are connected or interconnected can they offer that extra that we are looking for. But what are the reasons why it is worth spending a little more on such a system for our air conditioning?
Choosing a connected air-conditioning system can be interesting, as it offers greater ease of use. It is a control method that can eventually replace the remote control of our air conditioning, which can be managed by a smartphone or tablet. In both cases these can become the hub of home air conditioning. And if we think about it, we have our cell phone around all day, so what better remote control?
