Before we tell you how to choose an air conditioner for your home, let’s define the basic concepts. Customers don’t always feel the difference between air conditioning and ventilation, we would like to fix that.
The air conditioning system is an air cooling system that operates in recirculation mode. Air conditioners lower its temperature, maintaining the set value, but do not affect air exchange. Some models have the function of adding fresh air, but they are not able to provide enough of it for the complete comfort of residents.
Whereas the ventilation system provides controlled air exchange in the premises, creating a comfortable and healthy microclimate, it is responsible for the quality of the air: it utilizes carbon dioxide (CO2) emitted by humans, supplies fresh, pre-purified air of a comfortable temperature from the street (in the case of a ventilation system with heat recovery).Let’s go back to the selection of an air conditioner for a private house or cottage. Choosing it is not as easy as it seems at first glance. From Climate Environmental you can opt for the best air conditioning.
How to choose an air conditioner for your home
Contrary to popular belief, air conditioners are chosen not only for the square of the room.
The optimal view and model are selected based on 2 main parameters:
- Heat engineering calculation.
- Static pressure (the force with which the fan of the indoor unit will provide air flow) – for ducted air conditioners.
- Let’s take a closer look at the main selection criteria.
Heat engineering calculation for choosing an air conditioner
Within the framework of the heat engineering calculation, many factors are assessed:
- orientation of the building to the cardinal points
- energy efficiency of the house structure;
- exterior wall material
- quality of double-glazed windows
- roofing material
- the size of the windows and their total area
- ceiling height
- the amount of fresh air coming from the street
- the number of people regularly in the rooms
- The level of heat radiation from household appliances.
These parameters are extremely important, since they affect the cooling system, the power consumption, and, accordingly, the choice of the power of the air conditioner itself.
When selecting duct air conditioners, special attention is paid to the parameters of static pressure. That is, the ratio of the pressure of the air conditioner to the aerodynamics of the air ducts, the longer the length of the air duct, the more pressure should be.
Accordingly, it is first necessary to study the duct system, their length and branching system, and on the basis of these data calculate the required static pressure of the duct air conditioner. That is why it is important to take seriously the choice of a design company – it bears responsibility for the correct operation and power of the system.
Types of air conditioners for home
This is the most popular and demanded type. It is a split or multisplit system: with one outdoor and one or more indoor units, respectively. The latter are mounted indoors, under the ceiling, often near the window. Wall mounted air conditioners are effective in small rooms. They consume a little electricity and, depending on the model, have additional options: air humidification, cleaning and disinfection, night mode, timer, smartphone control, “smart eye” mode, outdoor unit noise reduction mode, etc.
