No, you cannot use a split-type air conditioning indoor unit without the outdoor unit. Split-type air conditioners consist of two main components: the indoor unit and the outdoor unit, and they are designed to work together as a complete system.
The indoor unit of a split-type air conditioner is responsible for blowing conditioned air into the room, while the outdoor unit houses the compressor and other vital components responsible for cooling the refrigerant. The refrigerant circulates between the indoor and outdoor units, absorbing heat from the indoor air and releasing it outside.
Without the outdoor unit, the indoor unit will not be able to cool the air effectively. The outdoor unit plays a crucial role in the cooling process, as it is responsible for compressing the refrigerant and facilitating the heat exchange necessary to cool the indoor air. Attempting to use the indoor unit without the outdoor unit would not provide any cooling effect, and the indoor unit may not even function properly.
If you need an air conditioning system for cooling, it's essential to have both the indoor and outdoor units properly installed and working together as a complete split-type air conditioning system. If you're looking for a portable cooling solution, you might consider using a standalone portable air conditioner that doesn't require an outdoor unit and can be easily moved from room to room.
