Concurrent heating system for air conditioning system of automobile and control method thereof

Abstract

The invention relates to a concurrent heating system for an air conditioning system of an automobile and a control method thereof. The system comprises an air conditioner control module, an outdoor temperature sensor, an indoor temperature sensor, an electric ceramic heating body PTC, an engine speed sensor and an engine control module, wherein the outdoor and indoor temperature sensors are in communication connection with the air conditioner control module; the engine speed sensor is in communication connection with the air conditioner control module and / or the engine control module; the electric ceramic heating body PTC is in electric connection and / or communication connection with the air conditioner control module, and the on and off of the electric ceramic heating body PTC is controlled by the air conditioner control module; and the engine control module is in communication connection with the air conditioner.

Description

technical field [0001] The invention relates to a vehicle air-conditioning and heating system, in particular to an auxiliary heating system of an automobile air-conditioning system and a control method thereof. Background technique [0002] In order to improve the comfort of the car, in autumn and winter when the outdoor temperature is relatively low, the car air conditioning system will use the high temperature of the engine circulating cooling water to provide warm air at a suitable temperature for the car interior to meet the needs of human comfort. When the engine cooling circulating water enters the heater core inside the air conditioner HVAC with a high residual temperature, the high-speed airflow provided by the blower passes through the heater chip to take away part of the heat, turning the cold air into warm air and passing through the air The air blows into the cab, increasing the indoor ambient temperature and making people feel warm and comfortable. However, in ...

AI Technical Summary

Problems solved by technology

The configuration of modern cars is gradually improving, all because the requirements for vehicle comfort and safety are getting higher and higher, and the traditional slow heating process can no longer meet people's requirements for car air-conditioning systems in cold winter

That is, the following technical problems exist in the prior art: the existing automotive air-conditioning system cannot quickly complete the temperature increase in the car within the required time.
