    摘要： A refrigeration cycle apparatus includes a low temperature-side refrigeration cycle 110, a high temperature-side refrigeration cycle 120, defrosting detecting means 116 which detects a frost-formed state of the low temperature-side refrigeration cycle 110, and a controller 140. When an operation should be shifted to a defrosting operation for thawing frost of the low temperature-side evaporator 114, an operation of the low temperature-side compressor 111 of the low temperature-side refrigeration cycle 110 is continued, an operation of the high temperature-side compressor 121 of the high temperature-side refrigeration cycle 120 is stopped, and the operation is shifted to the defrosting operation. When the operation is shifted to the defrosting operation, heat-accumulated high temperature low temperature-side refrigerant is supplied to the low temperature-side evaporator 114 to defrost. Therefore, it is possible to shorten the defrosting time and to enhance the operation efficiency of a refrigeration cycle.

    摘要： A refrigerating system (2) according to the invention comprises at least one refrigerant circuit (4) having a set of compressors (6, 8, 10), each of said compressors (6, 8, 10) being operable at least one compressor power stage, a control unit for the set of compressors (6, 8, 10), a liquefied (12), an evaporator also forming a heat exchanger (14), refrigerant conduits connecting the set of compressors (6, 8, 10), the liquefied (12), and the heat exchanger (14), and circulating a refrigerant, and a pressure sensor (16) arranged between the heat exchanger (14) and the set of compressors (6, 8, 10) sensing the refrigerant pressure; a cold carrier circuit (22) having a cold carrier pump (36), a cold consumer region (24), cold carrier conduits connecting the cold carrier pump (36), the heat exchanger (14) and the cold consumer region (24) and circulating a cold carrier, which is refrigerated in the heat exchanger (14), and a temperature sensor (26, 28) sensing the cold carrier temperature. The control unit for the set of compressors (6, 8, 10) is configured such that, in case of the temperature sensor (26, 28) sensing a too high cold carrier temperature, it prevents turning on additional compressor power stages, if the refrigerant pressure is below a first critical value (pmin + Δpi) and decreases, and it switches off at least one running compressor power stage, if the refrigerant pressure falls below a second critical value (pmin - Δp2).
