Conductive sealing requires a rigid metal plate in perfect contact with the container being sealed. Conductive seal systems delay production time due to the system warm-up time required. [citation needed] They also have sophisticated temperature sensors and heaters.Unlike conduction sealing systems,

Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves the controlled heating of a conductive object (usually aluminum foil) by electromagnetic induction through the heat generated in the object by eddy currents.Induction sealing is used in many types

The A320 aircraft air conditioning system​ mainly consists of four major parts: regional temperature control, electronic equipment ventilation, pressurization system, cargo compartment ventilation/heating (optional). The cooling air is provided by two refrigeration components. The components are based on the principle of turbocharged refrigeration, and their performance directly affects the comfort of the cabin and cockpit.
