What are the primary components of a split air conditioning system?

The primary components of a split air conditioning system are indeed the indoor and outdoor units. In a split system, the indoor unit is responsible for cooling and distributing the air within the space, while the outdoor unit contains the compressor and is responsible for dissipating heat from the refrigerant to the outside environment. This configuration allows for more efficient cooling and quieter operation inside the building, since the noisier components like the compressor are located outdoors.

While other components like the fan, evaporator, condenser, compressor, and expansion valve are crucial to the operation of the air conditioning system, they are typically included in the broader categorization of the indoor and outdoor units. Understanding the distinction between the units helps through the conceptualization of how the system functions as a whole.
