What is the component of a Split-type air conditioning system that is located outside the house?

The component of a split-type air conditioning system that is located outside the house is the condenser. The condenser plays a crucial role in the refrigeration cycle of the air conditioning system. Its primary function is to remove heat from the refrigerant that has absorbed heat from the indoor environment, allowing the refrigerant to condense from a gaseous to a liquid state.

When the refrigerant exits the evaporator (the indoor unit), it is in a low-pressure gas state and carries the heat absorbed from inside the building. The gas then travels to the condenser, where it is compressed and radiated to the outside environment. As the heat dissipates, the refrigerant condenses, turning it into a high-pressure liquid that is then cycled back to the indoor unit to repeat the process.

In contrast, the evaporator is located indoors; the FCU (fan coil unit) and AHU (air handling unit) are also components found within the indoor environment. This distinction highlights the specific role of the condenser in the overall air conditioning system.
