What is the primary function of the compressor in a split system air conditioner?

The primary function of the compressor in a split system air conditioner is to raise the refrigerant's pressure and circulate it throughout the system. In the refrigeration cycle, the compressor takes low-pressure refrigerant gas and compresses it, which transforms the gas into a high-pressure, high-temperature gas. This pressurized gas is then pushed through the condenser, where it releases heat and converts back into a liquid state.

This function is crucial because it allows the refrigerant to flow through the entire air conditioning system, enabling heat exchange processes to occur efficiently. By raising the pressure, the compressor ensures that the refrigerant can absorb heat from the indoor environment in the evaporator coil, maintaining the desired indoor temperature, and facilitating the entire cycle of heat removal.

Other options highlight different processes, such as absorbing heat or controlling refrigerant flow, which are also important in the overall operation of the system but do not define the primary function of the compressor.
