Description
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. Compression heat pump technology has better flexibility in thermodynamic performance, but the core component of the compression heat pump is a moving component, which brings many disadvantages-for example, noise generated in the operation of the compression heat pump is intolerable; for this reason, it is considered to reduce the use and number of large moving parts (mainly compressors and expanders).
In order to exert the technical advantages of the absorption heat pump and give consideration to the requirements of power drive or external power supply, the invention provides a temperature difference utilization link comprising a refrigerant liquid pump, a high-temperature heat exchanger, an expander and a compressor, which is used for effectively utilizing the temperature difference between a high-temperature heat source and a heated medium or the temperature difference between the high-temperature heat source and the environment and has comprehensive advantages.
