Heating and air-conditioning system for cab interior of electric motor vehicle, has switching units connect heat exchanger in one of air paths, where one air path opens outside cab interior without passing through air treating device

摘要

The system (20) has a heat exchanger (21) comprised in a cooler that cools an electric drive engine of a motor vehicle i.e. electric motor vehicle, where the system defines an air path (52). An air treating device i.e. pollen filter (35), treats the air circulating along an air path that opens in a cab interior (7) of the vehicle. Switching units i.e. valves (37, 38), connect the heat exchanger in one of the air paths. The air path (52) opens outside the cab interior without passing through the air treating device. An independent claim is also included for a motor vehicle comprising a heating and air-conditioning system.
