Review on Split system LG P12SP, white by Danuta Nowak ᠌

If this is your first air conditioner and you are worried about noise, don't worry. If you want to take one air conditioner for the whole apartment - it won't work if you don't have a studio :) Finally, if you don’t believe and don’t understand how it produces ~ 3.5 kW of cold / heat, consuming ~ 900 W of electricity, I’ll tell you: energy conversions are not direct, it’s not electricity that does the work, but the refrigerant, electricity is spent only on to "make" the refrigerant work. In the air conditioner, in principle, there are no noisy components and devices: the compressor makes noise like a refrigerator, the fan - like a fan, that's all that creates noise in it. The operation of the inverter control is not clear, and on the noisiest thing - the fan of the outdoor unit, there is no smooth speed control at all. Why the operation of the inverter is not clear, because the compressor here is on a brushless DC motor, closed in a casing, and the difference in its speed cannot be heard also because of the fan noise. By the way, it is not louder than the engine of an electric scooter. Dual inverter is about the structure of the compressor rotor, and not about the presence of two inverters, if anything;) In case anyone is wondering, switching from heating to cooling and vice versa is done using a valve that changes the direction of the refrigerant flow (the user just needs to select the mode). The minimum length of the route is 3 meters, the maximum is 15 m, the location of the blocks in height relative to each other does not matter (up to 7 meters of height difference), the main thing is that the condensate drain is at an angle; During installation, the following are used: interconnect cable 4x1.0, supplying 3x1.5 (it is better to take a section larger), pipes 1/4 and 3/8, drainage 16 mm, bracket L=450, hole in the wall d ~ 60 mm :)
