Abstract
In an absorption type cold and warm water system, a solution pump and a refrigerant pump are operated when a heat source serving as a drive source of the absorption type cold and warm water system is rendered inoperative as a result of the temperature of cold water and warm water produced by the system reaching an OFF value set beforehand for the heat source. This enables refrigerating and heating abilities stored in the cold and warm water system to be effectively utilized.
