Improved Carnot cycle method

Abstract

The invention discloses an improved Carnot cycle method which comprises the steps that heat is input through a high-temperature heat input end and used for maintaining a high-temperature heat source which outputs heat to high-temperature total heat output; heat of high-temperature total heat output absorbs and is mixed with heat of low-temperature heat output through a high-temperature driving heat pump or other mechanical or non-mechanical work driving heat pumps; heat of high and low temperature mixed heat energy output is transferred to a medium temperature heat source and used for maintaining the medium temperature heat source; medium and low temperature output effective work is output after medium temperature total heat output for doing work of the medium temperature heat source does work through a medium and low temperature heating machine, and heat of waste heat output after medium and low temperature work is transferred to a low-temperature heat source. By means of the Carnot cycle method, Carnot cycle and reverse Carnot cycle are combined together to maintain the high temperature heat source, the medium temperature heat source and the low temperature heat source, the medium temperature heat source outputs work to the outside when transferring heat to the low temperature heat source through a Carnot heat machine, waste heat does not need to be dissipated after being transferred to the low temperature heat source, and waste heat and newly-supplemented heat enter the next work cycle through a heat pump. Therefore, heat efficiency is increased greatly.

Description

technical field [0001] The invention relates to Carnot cycle, in particular to an improved Carnot cycle method. Background technique [0002] The Carnot cycle was proposed by N.L.S. Carnot in 1824 when he conducted a theoretical study on the maximum possible efficiency of a heat engine. Carnot further proved the following Carnot theorem: ①The efficiency of all reversible heat engines working between the same high-temperature heat source and the same low-temperature heat source is equal, regardless of the working substance, where T1 and T2 are the high-temperature and low-temperature heat sources respectively. absolute temperature. ②The efficiency of all irreversible heat engines working between the same high-temperature heat source and the same low-temperature heat source cannot be greater than that of the reversible Carnot heat engine. Reversible and irreversible heat engines undergo reversible and irreversible cyclic processes, respectively. [0003] Carnot's theorem cl...

Problems solved by technology

Early humans did not have the ability to efficiently transfer heat and working fluids with heat from low-temperature heat sources to high-temperature heat sources, but now there are many ways to achieve high-efficiency heat transfer, some need to consume work, and some only need heat. To achieve heat "transportation", it is time to study less heat loss, less mechanical work, recycle and reuse "waste heat", and greatly improve the thermal power conversion efficiency of the system
