1-6. Thermal and Airflow
The internal and external air flow circulation is shown as the figure. Through separated mechanism
design, internal and external air flow won’t be mixed since the waste heat can be dissipated from the
cabinet to the ambience. Internal temperature sensor is placed at return air stream to provide reliable
temperature measurement and safety of operation.
The waste heat generated from the internal equipment will be absorbed by the refrigerant through the
evaporator and dissipate to the ambience by the condenser of external side.
