Organic rankine cycle system comprises pump, vaporizer, decompressor, generator, condenser etc.Heat collector absorbs solar irradiance, and in heat collector, heat exchange medium temperature raises, and heat transferring medium is passed to organic working medium by vaporizer heat.Organic working medium is level pressure heating in vaporizer, and the gaseous state organic working medium of high pressure enters decompressor expansion acting, drives generator generating; The organic working medium that decompressor afterbody is discharged enters level pressure condensation in condenser, and the organic working medium of condensator outlet enters vaporizer and completes power generation cycle one time after pump pressurization.
Organic rankine cycle system exists conversion efficiency not high, and volume is large, need to be by baroque decompressor acting.
In line engine compact dimensions, stability is high, and low-speed torque characteristic is good and fuel consumption is also less, and resultant is that manufacture cost is also lower; Going deficiency is that power is lower, is difficult to be applicable to being equipped with automobiles more than 6 cylinders.
