Description

 Compound type II absorption heat pump

Technical field:

 The invention belongs to the technical field of low temperature waste heat utilization and heat pump.

Background technique:

 The second type of absorption heat pump uses the temperature difference between the waste heat medium and the cooling medium (cold environment) as the driving force. When the driving temperature difference is large, the double-effect or multi-effect process should be adopted to realize the full utilization of the residual heat; any heat transfer link The waste of temperature difference will bring about a reduction in the utilization rate of heat energy. Only by making full use of the temperature difference can a reasonable thermodynamic perfection be obtained.

 Where the sensible heat is provided by the waste heat medium, the temperature difference between the high temperature heat release portion and the low temperature heat release portion of the waste heat medium and the cooling medium is different, and there is often a relatively high temperature between the heat temperature medium and the low temperature portion of the cooling medium. Large temperature difference. At this time, if the solution generation process is completed in a single-effect process, the temperature difference is not fully utilized, and the thermodynamic perfection and performance index of the cycle are not ideal; if the solution process is completed by the classic double-effect process, the residual heat medium and the cooling medium are required. There must be enough temperature difference between them, which requires a new cycle to achieve the full use of the temperature difference in this case.

 In addition to eliminating large heat transfer temperature differences, the second type of absorption heat pump cycle process needs to fulfill more requirements, including: smooth changes in thermodynamic parameters, adjustable heating parameters, and better adaptability The change of condition has the best performance index; it can realize the deep utilization of waste heat resources and the second type of temperature difference, or use the waste heat of different grades to realize the comprehensive utilization of waste heat.

 The invention provides a series of composite generation heat absorption pumps which are formed by a classic single-effect process and a generation-absorption double-effect process to form a composite generation process, so as to improve the utilization value and heat utilization rate of the residual heat load.
