Abstract:
To provide an absorptive refrigerator capable of operating IPLV in a state of being kept within a range of an allowable error.SOLUTION: An absorptive refrigerator comprises a high-temperature regenerator 5, a low-temperature regenerator 6, an evaporator 1, a condenser 7 and an absorber 2, and forms a circulation passages for absorbing liquid and refrigerant by connecting them with pipes. When it is determined in the vicinity of a plurality of cooling loads whether the difference between a cold water setting temperature and a cold water outlet temperature is within a predetermined range, which is a stable condition, and whether a cooling water outlet temperature is within a predetermined range, respectively, and the stable condition continues for a predetermined time, a controller 51 performs correction processing of controlling the inverter frequency of a rare absorbent pump 45 to be lowered, in a case where an assumed concentrated liquid concentration is lower than a predetermined value.SELECTED DRAWING: Figure 2
