PROBLEM TO BE SOLVED: To provide a load distribution system capable of restricting deterioration of energy efficiency of an entire system by setting appropriately a flow rate of thermal medium distributed to each of a heat source machine having a variable speed compressor, a heat source machine having a constant speed compressor or an absorbing type heat source machine.SOLUTION: A load distribution system comprises: a first freezer 51, a second freezer 52 arranged in parallel with the first freezer 51, secondary side facility 20, and a thermal medium circulation circuit 70. The first freezer 51 is a heat source machine having a variable speed compressor. The second freezer 52 is either a heat source machine having a constant speed compressor or an absorbing type heat source machine. The thermal medium circulation circuit 70 comprises a pump 40 for circulating thermal medium to the thermal medium circulation circuit 70; a first flow rate adjusting valve 61 for adjusting a flow rate of thermal medium flowed from the pump 40 toward the first freezer 51; and a second flow rate adjusting valve 62 for adjusting a flow rate of thermal medium flowed from the pump 40 toward the first freezer 52 that are all common to those of the first freezer 51 and the second freezer 52.SELECTED DRAWING: Figure 1 |
