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.
A heat energy (temperature difference) utilization technology represented by an absorption heat pump technology, and high-temperature heat load driving is utilized to realize heat supply or refrigeration; but the application field and the application range are greatly limited due to the influence of the properties of the working media (solution and refrigerant media).
