No, it is not possible to install a split air conditioner without a condenser. A split air conditioner consists of two main components: the indoor unit (evaporator) and the outdoor unit (condenser). The indoor unit is responsible for cooling the air inside the room, while the outdoor unit releases the heat absorbed from the indoor unit to the outside environment.
The condenser is a vital part of the air conditioning system as it facilitates the release of heat from the refrigerant. It contains a compressor, condenser coils, and a fan to dissipate the heat. Without a condenser, the heat generated by the indoor unit cannot be effectively expelled, and the air conditioning system will not function properly.
So, to install a split air conditioner, both the indoor and outdoor units, including the condenser, are necessary for the system to operate efficiently.
