What is the primary function of the compressor in an environmental control unit (ECU)?

The primary function of the compressor in an environmental control unit (ECU) is to deliver refrigerant. The compressor plays a crucial role in the refrigeration cycle by compressing low-pressure refrigerant gas and transforming it into high-pressure gas. This high-pressure gas is then routed through the system to cool the interior of the ECU or any other connected environment.

Once the gas is compressed, it moves to the condenser, where it releases its heat and condenses into a liquid before proceeding through the system again. This function is essential for maintaining the temperature and preserving the necessary environmental conditions for medical equipment and patients. Other components of the ECU manage different aspects like air filtration and temperature measurement, but those functions do not encompass the primary role of the compressor, which is centered on the refrigeration cycle.
