Title (EN) REFRIGERATION MACHINE
(FR) MACHINE FRIGORIFIQUE
(JA) 冷凍機
Abstract:
(EN) The purpose of the present invention is to provide a refrigeration machine wherein lubricating oil supplied to a bearing, etc. in a turbo compressor is capable of being cooled by a simple configuration. This refrigeration machine (1) comprises: a refrigeration cycle in which a refrigerant circulates, the refrigeration cycle being provided with a turbo compressor (2) having a compression mechanism driven by a motor, the refrigeration cycle being further provided with a condenser (3) and an evaporator (8); an oil tank (23) in which lubricating oil is stored; a lubricating oil supply line (22) for supplying lubricating oil from the oil tank (23) into a motor housing (31) containing the motor; and a liquid refrigerant supply line (24) for supplying a refrigerant from the condenser (3) into the motor housing (31).
(FR) Le but de la présente invention est de fournir une machine frigorifique dans laquelle de l'huile de lubrification fournie à un palier, etc, dans un turbocompresseur peut être refroidie par une configuration simple. Cette machine frigorifique (1) comprend: un circuit frigorifique dans lequel circule un fluide frigorigène, pourvu d'un turbocompresseur (2) ayant un mécanisme de compression entraîné par un moteur, ainsi que d'un condenseur (3) et d'un évaporateur (8); un réservoir d'huile (23) dans lequel de l'huile de lubrification est stockée; une conduite d'alimentation en huile de lubrification (22) pour fournir de l'huile de lubrification du réservoir d'huile (23) au carter de moteur (31) contenant le moteur; et une conduite d'alimentation en fluide frigorigène en phase liquide (24) pour fournir un fluide frigorigène du condenseur (3) au carter de moteur (31).
(JA) 簡素な構成でターボ圧縮機の軸受等に供給される潤滑油を冷却することが可能な冷凍機を提供することを目的とする。冷凍機(1)は、モータによって駆動する圧縮機構を有するターボ圧縮機(2)と、凝縮器(3)と、蒸発器(8)を備え、冷媒が循環する冷凍サイクルと、潤滑油が貯留された油タンク(23)と、油タンク(23)からモータを収容するモータハウジング(31)内部へ潤滑油を供給する潤滑油供給ライン(22)と、凝縮器(3)からモータハウジング(31)内部へ冷媒を供給する液冷媒供給ライン(24)とを備える。
