To provide a heat cycle system capable of discharging and absorbing heat using light from a light source efficiently while suppressing an increase in energy consumption by the light source.SOLUTION: A heat cycle system includes: a heat exchange unit for discharging heat and outputting light of a second wavelength to a second optical transmission line when a system excited by light of a first wavelength from a first optical transmission line returns to a ground state, and absorbing heat and outputting the light of the first wavelength to the first optical transmission line when a system excited by the light of the second wavelength from the second optical transmission line returns to the ground state; a wavelength conversion part for converting the wavelength of the light from the second optical transmission line to the first wavelength and outputting the light of the first wavelength to the first optical transmission line, and converting the wavelength of the light from the first optical transmission line to the second wavelength, and outputting the light of the second wavelength to the second optical transmission line; and an optical path switch for causing the light of the first wavelength from the light source to be made incident selectively on either the heat exchange part or the wavelength conversion part through the first optical transmission line.SELECTED DRAWING: Figure 1 【課題】光源によるエネルギー消費量の増加を抑制しつつ、当該光源からの光を効率よく利用して熱を放出および吸収することができるヒートサイクルシステムの提供【解決手段】ヒートサイクルシステムは、第１光伝送路からの第１波長の光により励起された系が基底状態に戻るときに熱を放出すると共に第２光伝送路に第２波長の光を出力し、第２光伝送路からの第２波長の光により励起された系が基底状態に戻るときに熱を吸収すると共に第１光伝送路に第１波長の光を出力する熱交換部と、第２光伝送路からの光の波長を第１波長に変換して第１光伝送路に第１波長の光を出力し、第１光伝送路からの光の波長を第２波長に変換して第２光伝送路に第２波長の光を出力する波長変換部と、光源からの第１波長の光を第１光伝送路を介して熱交換部および波長変換部の何れか一方に選択的に入射させる光路切替器とを含む。【選択図】図１
