Description

Fourth type thermal driving compression-absorption heat pump
The technical field is as follows:
the invention belongs to the technical field of power, refrigeration and heat pumps.
Background art:
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 the process of achieving the above purpose, various conditions are faced, such as the type, grade and quantity of energy, the type, grade and quantity of user requirements, the type of working medium, the flow, structure and manufacturing cost of equipment, the safety of equipment operation, the acceptable degree of environmental temperature and environment, and the like.
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; due to the influence of the properties of the working medium (solution and refrigerant medium), a high-temperature heat load with an excessively high temperature or a low-temperature heat load with an excessively low temperature cannot be reasonably applied to the flow of the absorption heat pump, so that the application field and the application range of the absorption heat pump are greatly limited. The compression heat pump technology has better flexibility in the aspect of thermodynamic performance, but the core component of the compression heat pump is a moving component, so that higher safety is required for equipment operation, and the noise of the equipment operation needs to be reduced; for this reason, it is considered to reduce the use and number of large moving parts (mainly compressors and expanders).
