PROBLEM TO BE SOLVED: To provide economical and efficient refrigerating equipment adjusting the driving state of a compression refrigerating machine according to the state of cooling loads and absorption refrigerating effects. SOLUTION: This refrigerating equipment is formed by combining the absorption refrigerating machine having an evaporator E, with a compression refrigerating machine having one or more compressors Mc, a first condenser Cc1 cooling using outside air or cooling water, a second condenser Cc2 connected to the evaporator E of the absorption refrigerating machine in a heat exchange relation, and evaporators Ec exhibiting refrigerating effects. The compression refrigerating machine is provided with a pressure sensor in the absorption side from the evaporators Ec to the compressors Mc or a sensor detecting a physical quantity corresponding to the pressure. This refrigerating equipment combined with the absorption type and the compression type is provided with a means adjusting the capacity or the number of the compressors Mc under driving so as to make the value detected by the sensor to a target value. A frequency variably driving inverter is provided, at least, one of the compressors Mc and the inverter may be adjusted based on the detection value of the sensor. COPYRIGHT: (C)2004,JPO
