PROBLEM TO BE SOLVED: To construct a heat source system using low temperature with high energy utilization efficiency. SOLUTION: A cycle executing portion 1 is provided in which working gas G is circulated among four chambers, i.e., a high temperature heat sink chamber 4, a low temperature heat sink chamber 2, a high temperature heat radiation chamber 3, and a low temperature heat radiation chamber 5, so that simultaneously conducting a stirling cycle and an inverse stirling cycle. In the cycle executing portion 1: high temperature heat medium Na for inputting heat is subjected to heat exchange with the working gas G by a high temperature heater 4a of the high temperature heat sink chamber 4; low temperature heat medium Nb having low temperature heat for an object of utilization is subjected to heat exchange with the working gas G by a low temperature heater 2a of the low temperature heat sink chamber 2; heat medium Nc for outputting heat to a heat demander 9 is subjected to heat exchange with the working gas G by a high temperature radiator 3a of the high temperature heat radiation chamber 3; and refrigerant Nc for radiating heat is subjected to heat exchange with the working gas G by a low temperature radiator 5a of the low temperature heat radiation chamber 5. |
