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 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.

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 working media (solution and refrigerant media), high-temperature heat load cannot be reasonably applied to the flow process of the absorption heat pump, so that the application field and the application range of the absorption heat pump are greatly limited; the advantage of large latent heat of vapor of the technical refrigerant of the absorption heat pump cannot be exerted.

The compression heat pump technology utilizing the grade difference between the mechanical energy and the heat energy has certain flexibility; in many cases, however, it is difficult to achieve a reasonable utilization of the heat energy in such compression heat pumps. Meanwhile, the two heat pump technologies have the common disadvantage that the conversion of heat energy into mechanical energy cannot be realized during heating or cooling.

In order to exert the technical advantages of the absorption heat pump, and from the perspective of greatly increasing the temperature of the low-temperature heat load, aiming at utilizing the high-temperature heat load to supply heat or cool and considering the power drive or the external power supply requirement, the invention provides a fourth type of heat-driven compression-absorption heat pump which comprises components such as a compressor, an expander, a high-temperature heat exchanger and the like, effectively utilizes the temperature difference between a high-temperature heat source and a heated medium and the temperature difference between refrigerant liquid and the environment at the same time and has comprehensive advantages.
