Review on 🌬️ Portable Electric Air Conditioner Unit: 2-in-1 Cooling Solution with Remote, Timer, 3 Speeds, Tower Fan Function, 7L Water Tank, 2 Ice Packs - Ideal for Home, Office, Kitchen (White) by Paul Martindale

First, they defy thermodynamics. It can make your personal space feel a little cooler because you're filling it with cold ice water. As soon as the cooling water heats up, the damp room becomes warmer than before due to the waste heat from the fan motor. The air conditioner extracts the heat and pushes it out of the house. This thing just blows air out, and when you put it in front of you you can feel the evaporation on your skin, so body heat is lost to the fan's convection. Ask other engineers, just don't want to wait for your money. Tom H Cornelius, North Carolina
