UA92563C2 - Method and system for complex utilization of engine exhaust heat - Google Patents

Abstract

The invention relates to a method is claimed for complex utilization of engine exhaust heat, wherein liquid from engine cooling jacket is heated by heat from engine cylinders, after that one performs evaporation of heated liquid by means of heat of exhaust gases, vapor obtained in such way is used to obtain electric energy, worked out vapor of cooling liquid is condensed by vapor of high pressure refrigerant and condensate formed is cooled by liquid high pressure refrigerant with supply to the engine cooling jacket. The invention further relates to a system of complex utilization of engine exhaust heat that has connected to each other by pipelines an engine cooling circuit, fluid pump and condenser. Additionally system includes a steam generator, power electric generator, steam engine, steam generator of conditioner, inter-cooler, thermal pump, radiator, ejector and evaporator. Outlet of cooling circuit of the engine is connected in sequence to the fluid pump, steam generator, steam engine and steam generator of conditioner that is connected to ejector and intercooler. The intercooler is connected to power electric generator by inlet of the engine cooling circuit and thermal pump that is connected to ejector, evaporator and condenser, and the condenser is connected to radiator and ejector.

Description

connected to the input of the liquid pump, the output of which is connected to the input of the power steam generator, the output of the engine emissions is realized as follows: the output of the power steam generator is connected to the input: in the cooling circuit of engine 1, the heater of the steam engine, the output of which is connected coolant (for example, water or the first inlet of the steam generator of the air conditioner, antifreeze), which is then supplied by the liquid pump 2 to the first outlet of which is connected to the first inlet of the power steam generator 3, in which this liquid is evaporated at high pressure due to heat from the inlet of the steam generator of the air conditioner, and at other times from exhaust gases. The steam expands into the steam outlet of the intercooler connected to the inlet of the cooling engine 5, giving the mechanical work of the engine cooling circuit, the second inlet of the intercooler no, or converting it into electrical energy into the electric connected to the outlet of the heat pump, the first inlet of the trogenerator 4. Exhausted steam at a low pressure connected to the first outlet of the condensate pressure (for example, atmospheric) goes to the vaporizer, the second inlet of the heat pump is connected to the first of the generator of the air conditioner b, where it condenses and the outlet of the ejector, the second outlet of which is connected to partial subcooling. After that, it cools with the first inlet of the condenser, and the inlet of the ejector, the chewing liquid is additionally cooled in the inter- connected with the outlet of the evaporator, the inlet of which is cooler 7 and returns to the cooling con- connected with the pipeline connecting the first ru of the engine 1. At the same time in the steam generator the outlet of the condenser with the first inlet of the heat pump-conditioner 6 evaporates at high pressure sa, the second outlet of the condenser is connected to the refrigerant, the vapor formed enters the nozzle through the inlet of the radiator, the first outlet of which is connected to the ejector 11, where it expands and sucks the steam from the second inlet condenser, and the second low-pressure one from the evaporator 12. The vapor mixture of the inlet and the second outlet of the radiator and the electric generator is compressed in the diffuser part of the ejector 11 and connected to the pipeline connecting the second enters the condenser 9, where the outlet of the intercooler is condensed with the inlet of the cooling circuit. removal of heat from the outside air.

The system of complex utilization contains a spolunt is divided into two parts: the first through a system of technological pipelines, heat pump 8 enters the steam generator of con- ducts, the cooling circuit of the engine 1, liquid ditioner 6 through the intercooler 7, and the second throttle pump 2, steam generator power 3, electricity is generated in the throttle 13 and boils in the evaporator 12, torus 4, steam engine 5, steam generator air conditioner, forming cold that cools the interior of the car 6, intercooler 7, heat pump 8, condenser 9, near. In the presence of turbocharging, the hot air is cooled in the intercooler 7 by the radiator 10, ejector 11, evaporator 12, and the ejector 11, and in the case of insufficient cooling 13. it is further cooled in the radiator
