Automobile double-air-conditioner control system and method

Abstract

The invention relates to the technical field of automobile air conditioners, in particular to an automobile double-air-conditioner control system and method. The automobile double-air-conditioner control system comprises a compressor, a front air conditioner host assembly, a rear air conditioner top evaporator assembly, a front condenser, a receiver-drier, a front expansion valve and a rear expansion valve. A refrigerating agent is discharged into the front condenser from the compressor, is condensed through the front condenser, then flows to the receiver-drier, is filtered and dried through the receiver-drier and then branches into a first refrigerating agent entering the front expansion valve and a second refrigerating agent entering the rear expansion valve. The first refrigerating agent is throttled and depressurized through the front expansion valve, then enters the front air conditioner host assembly and finally returns back to the compressor. The second refrigerating agent is throttled and depressurized through the rear expansion valve, then enters the rear air conditioner top evaporator assembly and finally returns back to the compressor. By the adoption of the system and method, low-cost design of an air conditioner system is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile dual air conditioner control system and method. Background technique [0002] The automotive air-conditioning system is used to cool, heat, ventilate and purify the air in the cabin. It can provide a comfortable environment for the passengers. Therefore, people have higher and higher performance requirements for the air-conditioning system. [0003] At present, for light passenger vehicles, some dual air-conditioning systems adopt a structural scheme of two evaporators and one condenser, that is, the "double evaporator and single cooling" system. [0004] In the dual air-conditioning system, in order to realize the independent control of the front and rear evaporators, two solenoid valves are configured, and the customer can control the two solenoid valves separately according to the needs, so as to achieve the purpose of separately controlling t...

AI Technical Summary

Problems solved by technology

[0009] figure 2 In the dual air-conditioning system shown, it is possible to turn on the front air conditioner without turning on the rear air conditioner, which is also in line with the actual operation of dual air conditioners in the vehicle. Air conditioner, and at this time there are no passengers in the rear row and there is no need to turn on the rear air conditioner, so the solenoid valve configured in the circuit of the rear air conditioner is a bit wasteful
