Organic Rankine cycle system, control method, control system and vehicle

Abstract

The invention discloses an organic Rankine cycle system, a control method, a control system and a vehicle. The organic Rankine cycle system includes an evaporation assembly, and the evaporation assembly includes an evaporator, a heat storage type evaporator and a bypass pipeline. The evaporator and the heat storage evaporator are arranged in series, the bypass pipeline is connected in parallel with the heat storage evaporator, one end of the bypass pipeline communicates with the working medium outlet of the evaporator, and the The bypass pipeline is provided with a second valve; an expander, the working medium inlet of the expander is in communication with the working medium outlet of the bypass pipeline and the working medium outlet of the heat storage evaporator; the condenser , the working fluid inlet of the condenser communicates with the working fluid outlet of the expander, the working fluid outlet of the condenser communicates with the working fluid inlet of the evaporating component, and the connection between the condenser and the evaporating component A working fluid pump is connected in series on the pipeline between them. The organic Rankine cycle system can be applied to tail gas waste heat recovery.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, and more specifically, relates to an organic Rankine cycle system, a control method, a control system and a vehicle. Background technique [0002] The organic Rankine cycle system in the prior art can only work stably under a constant heat source. However, the exhaust gas stability and flow of heavy trucks and other vehicles are constantly changing with the operating conditions of the vehicles, which leads to great limitations in the exhaust heat recovery process of diesel engines or gasoline engines for organic Rankine cycle systems. [0003] To sum up, how to apply the organic Rankine cycle system to exhaust waste heat recovery is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides an organic Rankine cycle system, which can be applied to tail gas waste heat recovery, and the present invention...
