cold demand, heat demand and power demand, which are common in human life and production; in reality, people often need to use high-temperature heat energy to realize refrigeration, heat supply or power conversion, and also need to use power to refrigerate or use power and combine low-temperature heat energy to supply heat. In achieving the above objects, various considerations or conditional limitations are faced, including the type, grade and quantity of energy sources, the type, grade and quantity of user demands, ambient temperature, the type of working medium, the flow, structure and manufacturing cost of the equipment, and so on.
