Air cooled centrifugal water chiller with refrigerant storage means

摘要: An air cooled centrifugal water chiller is disclosed which may be operable (1) under conditions of low outdoor ambient temperature, requiring flooding the condenser in order to reduce its capacity and maintain proper system operation; or (2) a heat recovery mode through provision liquid thereby accommodates portion all condensing load, also reduction flooding. In provide sufficient refrigerant within accommodate enumerated above, storage vessel provided communication with shell evaporator for receiving storing excess during those operating when it not required flood condenser. added feature lies suitable service valves isolating from compressor such that pumped into allow servicing evaporator. preferred embodiment, comprises an elongated pipe member connected at one end extending therefrom along axis generally parallel longitudinal extent
