In a split-type air conditioner, which component is not part of the outdoor unit?

In a split-type air conditioner, the outdoor unit is designed to house certain key components that facilitate the refrigeration cycle. The evaporator coil, which plays a crucial role in absorbing heat from the indoor air, is specifically located in the indoor unit rather than the outdoor unit.

The outdoor unit, on the other hand, contains the condenser, expansion valve (also known as the metering device), and the compressor. The condenser releases heat to the outside air, the compressor compresses the refrigerant, and the expansion valve regulates the flow of refrigerant into the evaporator coil. This setup allows the system to efficiently cool the indoor environment while dissipating heat outdoors.

Therefore, the evaporator coil is the correct answer as it is essential to the cooling process but is positioned within the indoor unit, distinguishing it from the components found in the outdoor unit.
