    摘要： Method for controlling a plural stage compressor comprising at least a first stage (10), a second stage (20) and a first inter-stage line (12) between the first stage (10) and the second stage (20), comprising the steps of:
    a- measuring the temperature at the inlet of the compressor,
    b- measuring the ratio between the outlet pressure (Pout) and the inlet pressure (Pin) of the first stage (10) of the compressor,
    c- calculating a coefficient (Ψ) based at least on the value of the inlet temperature (Tin) and on the measured pressure ratio (Pout/Pin),
    d- if the calculated coefficient (Ψ)is in a predetermined range, acting on a control valve (70; 76; 92) mounted in a line (4; 8) supplying the inlet of the first stage (10) of the compressor or in a gas recycle line (74) which opens into the first inter-stage line (12).

    摘要： There is disclosed herein a compressor control apparatus, and a refrigerator (700) including the same. According to the embodiments of the present disclosure, the operation of two compressors (C1, C2) may be controlled using an alternating current (AC) switch, thereby minimizing the use of elements as well as increasing the compressor capacity and enhancing the operation efficiency of a system. According to the embodiments of the present disclosure, a plurality of operation modes may be used to correspond to a load or freezing capacity using two compressors (C1, C2) . Furthermore, according to the present disclosure, two compressors (C1, C2) may be operated in a separate or simultaneous manner using a drive configured with two alternating current (AC) switches, thereby simplifying the configuration of a system to reduce the cost.

    摘要： The invention relates to an improved multi-stage centrifugal compressor (10) comprising at least four centrifugal compression stages (11,12,13,14), each including an impeller. The impellers of one pair of the stages (12,13) are mounted on a first shaft (23) coupled to a first high speed direct drive motor (16), and the impellers of another pair of the stages (11,14) are mounted on a second shaft (24) coupled to a second high speed direct drive motor (15). The speed of the first and second motors is controlled by at least one drive (25) such that the impellers are all driven at the same speed.

    摘要： A compressor (10) discharges a flow of compressed fluid at a predetermined temperature. The compressor includes a sensor (45) positioned to measure a first temperature indicative of the temperature of the compressed fluid, a coolant source (15), a cooler (30) positioned to receive a first flow of coolant from the coolant source and discharge a flow of cooled coolant, and a valve (40) positioned to receive the flow of cooled coolant and a second flow of coolant from the coolant source (15). The valve (40) is configured to discharge a coolant flow to the compressor (10) and the coolant flow has a ratio of cooled coolant to second flow of coolant that is variable in response to the first temperature.
