METHOD OF REGULATING HEAT RECOVERY SYSTEM IN VEHICLE Russian patent published in 2017 - IPC F01K23/06 

FIELD: automotive engineering.

SUBSTANCE: regulation of the heat recovery system in the vehicle with a heat recovery circuit (1) as a working circuit that contains a storage tank (VR) with a working fluid that is connected to, at least, one control valve (V1, V2) through the supply pump (SP), with which the corresponding heat exchanger (AGR-WT, AG-WT) is associated as an evaporator. The working circuit also contains an expansion machine (E) connected to, at least, one heat exchanger (AGR-WT, AG-WT) followed by a condenser (K), which is connected to the storage tank (VR) through the condenser pump (CP). At least, one heat exchanger (AGR-WT, AG-WT) is flowed both by the mass flow of the working medium and by the mass flow of the heat source heat carrier. In the case of the mass flow of the heat medium defined by the operating mode of the vehicle and a predetermined coolant temperature, a regulation is performed to a predetermined nominal vapour temperature and/or phase state for the working medium by varying the mass flow of the working medium through, at least, one heat exchanger/evaporator by regulating the transmission of the control valve (V1, V2).

EFFECT: reliability of the system operation.
