Description

Technical field: [0001] The invention belongs to the technical field of absorption heat pump and waste heat utilization. Background technique: [0002] In the field of absorption heat pump technology, there are the first type of absorption heat pump (absorption refrigerator) that uses the temperature difference between the high-temperature driving heat medium and the heated medium as the driving temperature difference, and uses the temperature difference between the waste heat medium and the cold environment (cooling medium) as the driving temperature difference. The temperature difference is the second type of absorption heat pump that drives the temperature difference, and the third type of absorption heat pump that uses the aforementioned two temperature differences as the driving temperature difference. According to the existing knowledge or point of view, in these three types of absorption heat pumps, the high temperature drives the heat release to the cold environment ...

Problems solved by technology

[0003] In the first type of absorption heat pump and the third type of absorption heat pump that provide high-temperature heat loads, those skilled in the art have encountered such a technical problem: in the absorption heat pump process represented by TFE-TDE high-temperature solution, the high-temperature generator Refrigerant vapor is released and refrigerant liquid is formed after releasing heat to the heated medium in the condenser; the latent heat of the refrigerant vapor is small, while the temperature of the refrigerant liquid is high and the sensible heat is relatively large, which leads to a very low performance index of the absorption heat pump , the heat energy utilization rate is not high, which greatly limits the application of the first type of absorption heat pump and the third type of absorption heat pump in the field of high temperature heating or cooling with high temperature heat load
