Description

Hydrogen fuel carrying same-light-heat combined cycle heat pump device

Technical field:

The invention belongs to the technical field of energy source carrying and combined cycle heat pumps.

The background technology is as follows:

Cold demand, heat demand, and power demand are common in human life and production; it is often necessary to use a high temperature heat source to perform refrigeration, heat supply, or conversion to power, and it is also necessary to use power to perform refrigeration or use power in combination with low temperature heat energy to perform efficient heating. In the process of achieving the above object, many factors are often restricted, and comprehensive technical means are needed to achieve efficient energy utilization.

Hydrogen belongs to high-quality energy and is fully utilized; the hydrogen is used as fuel to realize high-efficiency refrigeration and heating, and pure oxygen is used for supporting combustion to avoid the generation and emission of any pollutant. When hydrogen fuel is taken as input energy to perform refrigeration/heating, the realization of efficient utilization is a fundamental requirement, and the realization of the efficient utilization is realized by a combined heat pump cycle device. However, for a combined cycle heat pump apparatus comprising a brayton cycle, there is often a difficult-to-reconcile conflict between load, performance index and compression process step-up ratio; after extensive analysis, it was also found that there was also a significant temperature differential loss during the combustion of the hydrogen fuel.

The solar energy forms a high-temperature photo-thermal heat source through a heat collection technology means, and then the combined cycle heat pump device can be utilized to realize high-efficiency refrigeration/heating-however, due to factors such as a working principle, materials, safety and the like, the application value of the high-temperature heat source formed by solar energy collection is often not fully exerted, and a large improvement space is still provided.
