Abstract
(DE)
Wärmepumpenanlage mit einem Verdampfer und einem Verflüssiger sowie einem Turboverdichter, der von einem Elektromotor (17a) mit einem Stator (7) und einem vorzugsweise permanentmagnetisch erregten Rotor (6) angetrieben wird, wobei im Spalt zwischen dem Stator (7) und dem Rotor (6) ein Doppelspaltrohr (10) ausgebildet ist, das in seinem Inneren einen zu Kühlzwecken oder Isolierzwecken nutzbaren Hohlraum (12) aufweist.
(EN)
A heat pump system comprising an evaporator and a condenser and also a turbo compressor which is driven by an electric motor (17a) having a stator (7) and having a rotor (6) with preferably permanent-magnet excitation, wherein a double can (10) is formed in the gap between the stator (7) and the rotor (6), which double can has, in its interior, a cavity (12) which can be used for cooling purposes or insulation purposes.
(FR)
L'invention concerne un système de pompe à chaleur comprenant un évaporateur et un condenseur ainsi qu'un turbocompresseur qui est entraîné par un moteur électrique (17a) ayant un stator (7) et ayant un rotor (6) avec, de préférence, une excitation d'aimant permanent, une double boîte métallique (10) étant formée dans l'espace entre le stator (7) et le rotor (6), laquelle double boîte présentant, à l'intérieur, une cavité (12) qui peut être utilisée à des fins de refroidissement ou d'isolation.
