Abstract

L'invention porte sur un compresseur de réfrigérant qui comprend un contenant hermétique stockant une huile réfrigérante, un élément commandé électriquement et un élément de compression commandé par l'élément commandé électriquement. L'élément de compression comprend un bloc cylindre ayant une chambre de compression cylindrique et un piston cylindrique animé d'un mouvement alternatif dans la chambre de compression. La chambre de compression et le piston ont une différence de diamètre dans la plage de pas moins de 4 micromètres à pas plus de 15 micromètres. L'huile réfrigérante a une viscosité de 8 mm2/s ou moins à 40 degrés Celsius et est préparée par mélange d'une première huile réfrigérante ayant une viscosité de moins de 8 mm2/s à 40 degrés Celsius avec une seconde huile réfrigérante ayant une viscosité de 20 mm2/s ou plus à 40 degrés Celsius.
