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.

For ease of understanding, the following description is given:

(1) the high-temperature heat source is a substance for providing high-temperature driving heat load, and the temperature is relatively highest, namely a heat source medium or a high-temperature heat medium for short; such as high temperature combustion gases and the like.

(2) Medium temperature heat source-the substance that gets the heat load, the temperature is only lower than the high temperature heat source; such as a heated medium.

(3) Low temperature heat source-a substance providing low temperature thermal load, the temperature is lower than the medium temperature heat source, also called low temperature heat medium, such as waste heat medium; among the heat loads provided by the low-temperature heat source, a part of the heat loads is used as a driving heat load of the third type thermally driven compression heat pump, and the other part of the heat loads is used as a temperature-raising heat load.

(4) The second low temperature heat source, namely a substance which takes away low temperature heat load, is the lowest in temperature and is also called as a cold source medium; such as ambient air.

(5) When the heat source is directly used as a working medium to participate in the heat pump circulation flow, the heat source is the substance per se.

The specific implementation mode is as follows:

it is to be noted that, in the description of the structure and the flow, the repetition is not necessary; obvious flow is not described. The invention is described in detail below with reference to the figures and examples.
