The principle of operation is the following. From the water tank, water is sprayed and the fan spreads over a meter. In order for the air to actually come in colder, you need to lower the temperature in the tank to 3-4 degrees. To do this, you need to constantly report ice. Roughly speaking, the air enters 28 degrees, mixes with steam 2-4 degrees and air flies at you with a temperature of 4-5 degrees less. But this is clearly felt only if you sit at a distance of half a meter from the fan. My opinion. The simplest conder for 15-20 m2 costs 30k with installation. This thing cost 900. 3% of the cost. It has approximately the same efficiency compared to the simplest conder. But this is if you add ice and maintain the temperature in the region of 4-6 degrees. He also has a power supply of 1.5A. We have common adapters for 1a. Most likely, therefore, many wrote that their apparatus burned down. Works great from a portable battery at the output of 2.4A. The sound was a little annoying at first, but then I got used to it. The noise level is about the same as a gaming laptop when running at maximum speeds.
