Abstract
(EN)
This heat pump device (100) is provided with: a compressor (1) that compresses a refrigerant; a motor (8) that drives the compressor (1); an inverter (9) that applies a desired voltage to the motor (8); and an inverter control unit (10) that generates a pulse width modulation signal for driving the inverter (9) and that has, as operation modes, a heating operation mode for heating the compressor (1) and a normal operation mode for normally operating the compressor (1) and compressing the refrigerant, the inverter control unit periodically changing, in the heating operation mode, a carrier frequency, which is the frequency of a carrier signal.
(FR)
Dispositif de pompe à chaleur qui est pourvu : d'un compresseur (1) qui comprime un fluide frigorigène; d'un moteur (8) qui entraîne le compresseur (1); d'un onduleur (9) qui applique une tension souhaitée au moteur (8); et d'une unité de commande d'onduleur (10) qui génère un signal de modulation de largeur d'impulsion pour entraîner l'onduleur (9) et qui présente, en tant que modes de fonctionnement, un mode de fonctionnement de chauffage pour chauffer le compresseur (1) et un mode de fonctionnement normal pour actionner normalement le compresseur (1) et comprimer le fluide frigorigène. L'unité de commande d'onduleur change périodiquement, dans le mode de fonctionnement de chauffage, une fréquence porteuse, qui est la fréquence d'un signal de porteuse.
