Description

First-class thermally driven 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, type of low-temperature heat medium, flow, structure and manufacturing cost of the apparatus, 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 working media (solution and refrigerant media), high-temperature heat load cannot be reasonably and efficiently applied to the flow of the absorption heat pump, so that the application field and application range of the absorption heat pump are greatly limited, and the advantage of large latent heat of the refrigerant vapor in the absorption heat pump technology cannot be exerted.

In addition, the type, existence and temperature of the low-temperature heat source are important factors for restricting the absorption heat pump technology. For example, an absorption heat pump using a lithium bromide aqueous solution as a working medium is difficult to adapt to a low-temperature heat medium at a lower temperature, which severely restricts the application of the absorption heat pump.

In order to exert the technical advantages of the absorption heat pump, improve the utilization value of high-temperature heat load, solve the source and limiting factors of a low-temperature heat source, consider considering power drive or meet the external power requirement, the invention provides a first type of heat-driven compression-absorption heat pump which comprises a compressor, an expander, a high-temperature heat exchanger and other components, effectively utilizes the temperature difference between the high-temperature heat source and a heated medium or effectively utilizes the temperature difference between the high-temperature heat source and the environment and has comprehensive advantages.
