When the family needs efficient, quiet and reliable air conditioning just able to work without any problems for decades, it is better to choose the window or wall-mounted version, whose popularity in the domestic realities of growing from year to year.
Window models are prized for monoblock architecture. Main components in the form of a rotary compressor, evaporator and condenser are fixed on a single chassis and further interconnected copper alloy tubes. The system thoroughly evacuated, ie evacuated, and then pumped into the desired type of refrigerant (often - it is R410a) in the right amount.
When freon gas factory candy bar does not require regular refueling and it can surely work out a decade. For example, the Soviet air conditioners "BC", who work in our days. But do not get carried away b / vehicles and take a new version, which in addition to cooling, guarantee even heating.
Cooling power windows versions of the latest models can reach up to a solid mark - 18,000 BTU / hr. And it ensures lowering the temperature in the room area of 55 m2. In this case, the power consumption will not be as large - up to 1.5 kW / h, which is much smaller than seen in "BC". Noise pressure at the latest models' window air "is also small - less than 45 dB.
Lack of available - the difficulty of increasing power, as automatically increase the overall components of the air conditioner. In this case it is reasonable to choose the wall air conditioning with separate architecture - compressor units and a hairdryer deliberately set individually. Cooling power could reach serious figures - 24,000 Btu / h, and noise does not exceed 38 dB at the peak values. If you turn on the air conditioning system in the night mode, the noise level drops even twice.
If the majority of window air conditioners are equipped with rotary compressors, ability to make at any voltage, the wall model budget category are equipped with piston or rotary compressors options, ability to make confident at 220 IN. In this case the noise level of the compressor unit is not more than 56 dB, and it will not bring discomfort neighbors.
The best models of such equipment is often equipped with inverter compressors, which are easy to plant from 145 V and ensures extremely low power consumption. Without reason, they have the class A efficiency, which is indicated in the EER and reaches up to 4 units, and considered the best choice for those families who have air conditioning equipment works not only in summer but also in winter - efficiency reaches all 60%!. In this case, the load on the refrigeration "iron" is so low, the equipment without any problems will be able to work a decade.
