An absorption cold and warm water system utilizing solar heat includes a low temperature heat generator using as a heating source low temperature warm water obtained by heating water by the solar heat, a high temperature generator using an ancillary heat source as a heating source when the system runs short of the solar heat, and a low temperature generator. The cold and warm water system is provided with an operation device operative, when the cold and warm water system is in condition in which refrigerating and heating outputs can be provided by using the low temperature warm water, to allow the low temperature warm water to be continuously fed to the cold and warm water system and to control the volume of a solution and a refrigerant in circulation in accordance with temperatures of the cold and warm water. The solar heat is thereby stored in the cold and warm water system.
