  • Patent number: 6701730
    Abstract: In a refrigerating apparatus using an HFC group refrigerant, the performance is improved by increasing the refrigerating capacity and a stable operation is made possible. In order to achieve this, a cycle system in a refrigerator is structured so as to connect a compressor, a condenser, a liquid receiver and a supercooler in this order. In an air-cooled separation type refrigerator, the liquid receiver is disposed within an air-cooled type condenser unit. Further, in the case where a flush gas is liable to be generated in a liquid pipe, a vapor-liquid separator is disposed within the compressor unit integral with an accumulator and separated therefrom by a partition plate.

  • Patent number: 4910968
    Abstract: A refrigerating apparatus has a refrigerating cycle including an electromotive compressor whose operational speed is variable in accordance with a drive frequency, and a control unit for operating the compressor at a frequency correspondent to a load so as to control the operation of the refrigerating cycle. Control of the operational frequency of the compressor by the control unit is effected on the basis of target super heat amounts of a discharged gas which is predetermined over an operational frequency range of the compressor. The target super heat amounts are set such that within a lower region of the operational frequency range, each target amount is larger than a super heat amount at which the maximum refrigeration capability is obtained at each operational frequency, so as to suppress a suction pressure of the compressor within an allowable limit for the compressor.
