Vehicle-mounted air conditioning system, control method of vehicle-mounted air conditioning system and vehicle

Abstract

The invention provides a vehicle-mounted air conditioning system, a control method of the vehicle-mounted air conditioning system and a vehicle. The system comprises a first heating pipeline, a secondheating pipeline and a controller. The first heating pipeline comprises an engine, an electronic control reversing valve and a warm air core, all of which are sequentially connected. The second heating pipeline comprises the engine, the electronic control reversing valve, a heater and the warm air core, all of which are sequentially connected. The controller is used for starting the first heatingpipeline or the second heating pipeline according to a selected working mode, wherein the first heating pipeline and the second heating pipeline are switched through the electronic control reversingvalve, and the warm air core is used for generating hot air. By the adoption of the system, the corresponding heating pipeline can be switched according to the selected working mode to conduct heating, heating efficiency is high, and the equipment occupied space is small.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle-mounted air-conditioning system, a control method of the vehicle-mounted air-conditioning system, and a vehicle. Background technique [0002] In related technologies, the air-conditioning and heating control system of new energy vehicles uses positive temperature coefficient (Positive Temperature Coefficient, PTC) water heating or air heating PTC to heat water or air for heating for customers, so as to achieve heating for customers. Wind for customer comfort adjustment. The air-conditioning and heating system of new energy vehicles needs to consume energy to heat water or wind to perform air-conditioning and heating in a certain mode. If the control method in the heating system cannot be synchronized with the new energy control mode, it will be greatly The power consumption of the whole vehicle leads to a reduction in battery life in pure electric mode. At the same t...

AI Technical Summary

Problems solved by technology

The air-conditioning and heating system of new energy vehicles needs to consume energy to heat water or wind to perform air-conditioning and heating in a certain mode. If the control method in the heating system cannot be synchronized with the new energy control mode, it will be greatly The power consumption of the whole vehicle leads to a reduction in battery life in pure electric mode. At the same time, because new energy vehicles have many control modes, they cannot be distributed in combination with the heating system under different control modes, resulting in complaints from customers on heating performance and vehicle energy. Consumption reduces the power of the vehicle and reduces the mileage of new energy vehicles
