The internal wall unit from Gree is ideal for multi-split air conditioning systems. With a capacity of 18000 BTU, this unit is suitable for spaces from 35m² to 40m², offering an efficient and cost-effective solution for cooling or heating different rooms. Installing it on the wall saves space, which is especially useful for balconies or gardens with limited room. It is important to ensure that the outdoor unit has sufficient capacity to meet the needs of the connected indoor units during operation. Placing it at a height of approximately 2 meters ensures even air distribution throughout the space, while attention should be paid to the unit's placement so that cool or warm air is not directed directly at the people in the room.
