A comment
Ergo ACM-0903 CH mobile air conditioner was purchased 2 years ago. It works noisily, and what to expect from an apparatus in which fans and a compressor are in one place. It works according to the principle: it draws air in with a fan, blows them through a cold evaporator, and then, in a cooled form, the air flows back into the room, and all the hot air enters the street through an exhaust pipe.
The model itself is compact, there is a handle at the top, holding it you can move the air conditioner. On the front side there is a control unit with indications. There is also a remote control, a rather modest design, without a display. A deflector is located just below the control panel.
Functionally equipped is not bad, though it will not work to regulate the fan speed. Air conditioning always runs at maximum speed. So choose you.
pros
easier things are with installation
Minuses
pipe binding, noise, poor performance
