The outdoor unit of a split-type air conditioner is designed to dissipate the heat absorbed from the indoor unit during the cooling process. This is done through a refrigeration cycle that involves compressing and expanding a refrigerant gas, which causes it to release heat. The outdoor unit contains the compressor, condenser, and a fan that blows air over the condenser to remove the heat. As a result, hot air is emitted from the outdoor unit.
Here are some of the reasons why the outdoor equipment of the split type AC emits hot air:
The Refrigeration Cycle
As mentioned earlier, the refrigeration cycle is the main reason why the outdoor unit emits hot air. The compressor in the outdoor unit compresses the refrigerant gas, which increases its temperature. The high-temperature, high-pressure gas is then passed through the condenser coil where it is cooled by the ambient air. The cooled refrigerant gas condenses into a liquid, releasing heat to the outdoor air. The liquid refrigerant is then passed through an expansion valve, where it is converted back to a low-temperature, low-pressure gas, ready to absorb heat again in the indoor unit.
Heat exchange The outdoor unit of a split-type AC relies on heat exchange to cool the refrigerant. The condenser coil in the outdoor unit is designed to transfer heat from the refrigerant to the ambient air. The fan in the outdoor unit helps to blow the air over the condenser coil, dissipating the heat into the outdoor air. This is why you feel hot air coming out of the outdoor unit.
Proper installation The installation of the outdoor unit is critical to ensure proper cooling and heat dissipation. The outdoor unit should be installed in a location with adequate airflow and ventilation. The unit should also be mounted on a stable surface and leveled to ensure proper operation. A poorly installed outdoor unit can lead to reduced efficiency and increased energy consumption.
Dirty condenser coils Dirty condenser coils can reduce the efficiency of the outdoor unit and cause it to emit hotter air. Dust, dirt, and other debris can accumulate on the coils over time, hindering the heat transfer process. This can cause the unit to work harder to cool the refrigerant, leading to increased energy consumption and hotter air.
Proper installation and maintenance are essential to ensure efficient operation.
