ABSTRACT:
A mode of operation of an air-conditioning installation of a compression cycle type helicopter cabin or cockpit air-conditioning installation is characterized in that it includes a start-up sequence controlled by an inverter controlling the motor-compressor associated with a condenser equipped with a fan and during which the fan of the condenser is first powered up, after which the motor-compressor is powered up to start it at a low speed, after which the motor-compressor is operated under its normal conditions as a function of the cooling requirements of the installation. Other features concern the mode of powering the motor-compressor in accordance with various atmospheric and operating conditions.
