Classic air conditioner consists of an external and internal units, which, in turn, consist of several important components.In the internal unit fan, we can see that enhances heat transfer in the heat exchanger.The heat exchanger (evaporator) performs the functions of the cooling air in the room by evaporating refrigerant of a particular type (R22, R407, R410, R410A).
conditioner outdoor unit consists of a fan, which enhances the air exchange in the condenser and evaporator, a compressor that pressurizes the refrigerant, facilitating the passage of material between the inner and outer block.Also present in the outdoor unit condenser cooling refrigerant after compression in the compressor.
To cool (or warm) room air conditioner must have a certain power.The power conditioner shows how much cold (heat), the device can produce.To distinguish each instrument cooling capacity and heating capacity (if the model has the option).If the air conditioner is a simple split-system or mobile monoblock, it is one block cooling / heating.In this case, the power of the indoor unit is used for cooling, can vary from 199 to 21 980 W, and the air conditioning power required for heating, for one block varies from 710 to 22,600 Watts.
If the device is multisplitnoy system (with several indoor units), each additional unit in a certain way affect the power of the air conditioner.For example, the power of the second unit in the cooling mode can range from 199 to 6800 W, and the power in the heated mode from 1240 to 6999 watts.
Power consumption of the air conditioner is different from the power of the device, which works on the heating / cooling down.For example, the air conditioner having cooling capacities of 2.5 kW and a power consumption of just 800 watts.This is due to the fact that the air conditioning did not cool the air, but only transfers heat from indoors to outdoors.
Additional Features in this case, is also its energy efficiency, expressed by the COP = heat output / input power and EER = cooling capacity / power consumption.Depending on the level of energy efficiency of air conditioners are a particular class (A-G), which is considered to be the best class A more accurate are the coefficients of SCOP and SEER, which take into account the efficiency of air conditioners allowing for the different climatic zones.
If you're wondering how to calculate the power of the air conditioner in general, you can focus on what to cool 10 square meters.meters standard rooms need a 1 kW power conditioner in the cooling mode.To heat the room in 25 square meters.meters need about 2 kW of power conditioner for heating.However, these data can be guided only as a reference.It is better that the calculations made by professionals (in the majors this service is free).
calculating the required capacity of the air conditioner, the staff of the supplier may take into account the receipt of such methods of heat in the room, like:
- inflow through the windows, the floor, the roof (based on the thermal conductivity of materials);
- flow of heat from people staying in the room (based on the number of people and activities they are engaged) and situated where the equipment (including electric power consumption, the coefficient of heat transfer of energy and other.);
- heat from appliances and lighting by opening doors to other rooms (including a total area the size of doors and premises), and others.
On the basis of such characteristics can make the most accurate calculations and to choose the optimum power for this air conditioning unit.
