ELECTRIC TRANSPORT MICROCLIMATE PROVISION SYSTEM Russian patent published in 2024 - IPC B60H1/00 

FIELD: vehicles.

SUBSTANCE: invention relates to electric transport and means of providing a comfortable microclimate in cabins of vehicles, mainly in cabins of urban electric transport. Electric transport microclimate provision system includes climatic unit with heat pump mode, storage battery temperature control system and cooling system made with possibility of heat removal of converter and electric transport drive. Climate system consists of a closed refrigerating circuit with a compressor, two liquid-freon heat exchangers-evaporators, which in heat pump mode act as heat exchangers-condensers, one of the heat exchangers-evaporators is part of the temperature control system, two expansion valves, two shutoff-control valves, four-way check valves. Thermostating system consists of a liquid-freon heat exchanger, which provides connection between the thermostating system circuit and the refrigerating circuit, and a pump. Cooling system consists of a liquid-freon heat exchanger, which provides communication between the cooling system circuit with the cooling circuit, a liquid-air heat exchanger connected to a circulation pump through an expansion tank, two control valves, as well as two inlets of a cooling system circuit from a converter and a drive.

EFFECT: use of heat losses from converter and drive during operation of electric transport in parking mode for cabin warming up before movement and during movement of electric transport in cold season, as well as use of heat released from storage batteries for operation of electric vehicle air conditioner in heat pump mode during transition period of the year.
