Technical field:

The invention belongs to the technical field of thermodynamics and heat pumps.

The background technology is as follows:

The fuel combustion releases high-temperature heat energy, and can be used for refrigeration or obtaining low-temperature load to realize high-efficiency heat supply. In most cases, the temperature of the cooling medium changes during refrigeration, the temperature of the heated medium also often changes during heating, and sometimes the heated medium has the characteristics and requirements of temperature change, high temperature and the like; from the low temperature heat source perspective, the two conditions of temperature change and temperature fixing are divided. Advanced heat pump technology is required to meet different conditions and requirements. Limited by factors such as working principle, a larger irreversible loss of temperature difference exists in the gas forming process, which unexpectedly provides opportunities for the efficient utilization of other energy sources.

The nuclear fuel is a high-quality energy source, and can realize refrigeration/heating by utilizing a single-cycle or combined-cycle heat pump device; however, due to factors such as the working principle, the material performance and the safety requirement, the application value of the nuclear fuel is difficult to fully develop in a refrigerating/heating system with nuclear energy as independent driving energy, and the performance index of the system has a large improvement space.

Statement regarding high grade fuel and nuclear reactor:

(1) High grade fuel: refers to a fuel in which the heat source formed by the combustion products is relatively high in temperature.

Correspondingly, there is low grade fuel, which refers to fuel with relatively low heat source temperature formed by combustion products.

(2) The method is limited by the prior technical conditions or material performance and other reasons, and particularly for fuels which need to provide driving heat load for the circulating working medium through indirect means, the grade of the fuels is divided by the temperature which can be reached by the circulating working medium under the prior technical conditions, namely, the fuel which can be reached by the circulating working medium is high-grade fuel, and the fuel which can be reached by the circulating working medium is low-grade fuel.

(3) In the invention, the temperature which can be reached after the circulating working medium discharged by the compressor 1 flows through the nuclear reactor 4 to absorb heat is lower than the temperature which can be reached after the circulating working medium flows through the heating furnace 5 to absorb heat and raise temperature, and compared with the temperature, the nuclear fuel belongs to low-grade fuel.
