We will go through each step and help you decide on the choice of an air conditioner for those who do not have one yet, or for those who want to purchase a different model for their apartment, summer cottage or office. And so, on the steps that you need to go through in order to determine the functions and parameters that you choose for yourself according to your needs.
The first thing to do to choose an air conditioner is to determine its type. They are divided into three groups, it all depends on where the air conditioner will be used.
RAC - Room Air Conditions - Household Air Conditioner
PAC - Packages Air Conditions - Industrial Air Conditioner
Unitaries are whole industrial air conditioning systems.
In turn, these groups include various types of air conditioners.
Household:
Monoblock (window, mobile, floor)
Split systems (Wall type, "Fixed" wall type)
Semi-industrial:
Split systems (Duct, cassette, ceiling, column, wall)
Industrial:
- Multizone
- Chiller-fan coil systems
- Central air conditioners
- Rooftop air conditioners
- Cabinet air conditioners
- Precision air conditioners
Let's move on to the functions and characteristics:
The very first and most important thing is the power, let's clarify right away, this is not the cooling power, this is the power consumption. In order to choose an air conditioner, you need to know that the power consumption is lower than the cooling power, some air conditioners use less energy than your kettle. Pay attention to such indicators Energy Efficiency Ratio (ERR) is the ratio of the consumed power to the cooling power, and the Coefficient of Performance (COP) is the ratio of the consumed power to the heating power, that is, the thermal coefficient. In household systems, usually ERR = 2.5 - 3.5, COP = 2.8 - 4.0, Now decide whether you need air heating or only cooling, you can choose an air conditioner with both a cooling function and a heating function.
An important point is the noise level of the air conditioner, usually this: for the indoor unit 26 - 36 dB, for the outdoor 38 - 54 dB, at home, of course, put the air conditioner with the smallest range. You should know the area of the refrigerated room; the power of the air conditioner is calculated from this indicator. We will not delve into all the details of the design of air conditioners, let's just say that the entire system consists of an outdoor unit (mounted outside the window) and an indoor unit (installed indoors).
