Automobile tail gas waste heat recycling positive and inverse combined cycle cold and hot electricity self-coupling system

Abstract

The invention discloses an automobile tail gas waste heat recycling positive and inverse combined cycle cold and hot electricity self-coupling system. System elements comprise a working medium evaporator, a heating preheater, a working medium pump, a condenser, a draught fan, an expanding machine, an electricity generator, a storage battery, a compressor, a throttle valve, an evaporator, a relay, a first stop valve, a second stop valve, a third stop valve and a fourth stop valve. An automobile tail gas waste heat recycling ORC electricity generation loop, an automobile tail gas utilization loop, an electric power storage driving loop, a winter air heating loop and a summer air conditioning refrigerating loop are formed by the elements. The system has the beneficial effects that through the cold and heat electricity self-coupling system, gradient utilization and system integration of automobile tail gas waste heat are achieved, multiple coupling modes can be achieved according to working conditions of different seasons, the poor conditions that an existing automobile air conditioner cannot stably work, and refrigerating and heating intermittency is insufficient are overcome, the requirement of a driver and passengers for refrigerating and heating comfort can be met well, and the good practicability is achieved.

Description

technical field [0001] The invention relates to a waste heat recovery and utilization technology, more specifically, the invention relates to a forward and reverse combined cycle cooling, heating and power self-coupling system for the recovery of automobile exhaust. Background technique [0002] As a means of transportation, automobiles have been used more and more widely in modern society, and the number of automobiles in our country is also increasing year by year, reaching more than 200 million at present. The problems created by so many cars are: [0003] (1) A lot of heat is wasted every year due to the emission of automobile exhaust; [0004] (2) The air conditioners of existing cars are driven by the car engine to achieve cooling (electric cars are driven by batteries to achieve cooling), which virtually weakens the driving power of the car, which not only affects the driving speed and mileage of the car, but also affects the driving speed of the car. The cooling an...

AI Technical Summary

Problems solved by technology

The invention makes full use of the automobile exhaust for power generation and the winter heating and summer cooling of the automobile, realizes the efficient utilization of the waste heat of the automobile exhaust, and makes the automobile air-conditioning refrigeration in the prior art virtually weaken the driving power, driving speed and mileage of the automobile It can be solved, which is not only beneficial to energy saving and environmental protection, but also improves the unfavorable conditions of unstable operation of automobile air conditioners and intermittent insufficient cooling and heating, and can better meet the comfort requirements of drivers and passengers
