Cool Mono (1 part) is a compact unit/machine that draws warm air from the room, then cools it, and blows the cold air back into the room. The hot exhaust air is discharged outside through the exhaust hose. The exhaust hose is routed outside through an opening (usually a window equipped with a flexible window seal).
Cool Air Split (2 parts) consists of 2 units – a so-called indoor unit (in the room), where, similar to the monoblock, warm room air is drawn in and cold air is released. The heat generated in this process is transferred to the outdoor unit/condenser via thin cooling lines. Due to the smaller hoses in split units, the required openings to the outside air are smaller than with monoblocks, and the waste heat is dissipated more efficiently. However, if you want to close the opening (e.g., a window), the split system must be disconnected. The monoblock also does not require an outdoor unit, which must always be located outside the room to be cooled during operation.
