HEAT SOURCE SYSTEM AND CONTROL METHOD THEREOF

摘要

It is an object to reduce variation in load among compressors. A heat source system constituted by connecting multiple heat source machines with respective independent refrigeration cycles in series, includes: an information acquisition unit (21) that acquires measurement values of operation frequencies of compressors from respective heat source machines; a load distribution change unit (22) that changes a load distribution currently assigned to each of the heat source machines such that the compressor's operation frequencies acquired by the information acquisition unit (21) are substantially equal; and a temperature determination unit that sets the hot/chilled water outlet temperatures of respective heat source machines according to the changed load distribution.
