A blower air flow sensor determines the rate or throughput of the air flowing into the interior space via an outlet opening. A blower air regulator controls a temperature setting device and an air quantity setting device in order to minimize the absolute v...

A cooling device (22) with controllable cooling power is used in air-conditioning equipment (10) for a vehicle (12). Cooling power is adjusted so that heat energy needed to heat up pre-cooled air is as low as possible. This minimum heat energy is determine...

The fan has a motor (60) and at least one drive transistor (72) for supplying the motor with electrical energy. The transistor has an overvoltage protection arrangement and is thermally coupled to the motor. The motor has a housing (62) to which the drive ...
