Novel internal combustion truck energy supply system and method coupled with vehicle air conditioner

Abstract

The invention relates to a novel internal combustion truck energy supply system and method coupled with a vehicle air conditioner, and belongs to the field of energy and power. The system is characterized in that the ORC coupled diesel engine energy system waste heat collection is from a first evaporator (5); an organic Rankine cycle subsystem of the system comprises a turbine (19), a low-pressureworking medium pump (20) and a high-pressure working medium pump (18). Compared with an existing related composite power system and method for recycling vehicle smoke waste heat, the system is mainlycharacterized in that the turbine (19) and the low-pressure working medium pump (20) are additionally arranged, so the energy utilization rate is increased, and heat emission is reduced. A telescopicbutterfly valve is adopted, so that backflow is avoided.

Description

technical field [0001] The invention relates to a novel internal combustion truck energy supply system and method coupled with a vehicle air conditioner, belonging to the field of energy and power. Background technique [0002] Diesel locomotives have a wide range of applications. However, its current heat conversion efficiency is only about 40%, and the remaining energy is mainly discharged to the environment in the form of waste heat, while the waste heat of the coolant accounts for 20-30%, and the exhaust waste heat accounts for 30-40%. Further improving its energy utilization efficiency and reducing pollution emissions is its future development trend. [0003] From the perspective of engine efficiency alone, it is very difficult to improve fuel utilization from the perspective of combustion after the direct injection gasoline engine technology and homogeneous charge compression combustion technology are adopted. [0004] In recent years, the use of ORC system to recove...

Problems solved by technology

[0005] According to the review, although adding ORC can effectively improve the overall energy efficiency of the vehicle, it will also increase the complexity of the system and the vehicle load; few scholars choose to couple the ORC system with the air conditioner (AC) system to compensate The defect that the air conditioner is idle in winter and only used when the temperature is high in summer leads to the low utilization rate of AC equipment; at the same time, when the season changes, the cooling / heating load requirements of the vehicle will also change, which will affect the overall performance;
