Circulating method and system of thermally driven heat bombing heat pump

Abstract

The invention provides a circulating method and system of a thermally driven heat bombing heat pump. The system comprises an intermediate-temperature driving set memory alloy, a high-temperature heatpump set memory alloy, an intermediate-temperature heat source, a high-temperature heat sink and a normal-temperature heat sink. The austenite final temperature Taf2 of the high-temperature heat pumpset memory alloy is lower than the temperature Tg of the intermediate-temperature heat source, but Taf2 is higher than the austenite final temperature Taf1 of the intermediate-temperature driving setmemory alloy, and the martensite final temperature Tmf1 of the intermediate-temperature driving set memory alloy is higher than the temperature Tc of the normal-temperature heat sink. The intermediate-temperature driving set memory alloy and the high-temperature heat pump set memory alloy are connected through a mechanical coupling component. The intermediate-temperature driving set shape memory alloy absorbs heat from the low-grade intermediate-temperature heat source with the temperature Tg, heat is discharged to the normal-temperature heat sink with the temperature Tc, driving force is provided for the heat pump set shape memory alloys, the heat of the intermediate-temperature heat source with the temperature Tg is released to the high-temperature heat sink with the temperature Th, andthe grade of low-grade heat energy is improved.

Description

technical field [0001] The invention belongs to the field of thermal energy treatment, and in particular relates to a heat-driven elastothermal heat pump cycle method and system. Background technique [0002] Energy shortage and environmental pollution have become a problem that cannot be ignored in the development process of our country. The energy consumption in my country's industrial field accounts for about 70% of the total energy consumption in the country. In addition to factors such as immature production technology, unreasonable production capacity structure, and extensive development, the utilization rate of industrial waste heat is low, and energy has not been fully and reasonably utilized. Utilization is an important reason for high energy consumption. According to the survey, the total waste heat resources of various industries in my country account for about 17% to 67% of the total fuel consumption, of which the recyclable waste heat accounts for about 60% of t...
