Abstract

The invention discloses a double-evaporator air conditioning system. The double-evaporator air conditioning system comprises a front evaporator, a rear evaporator, an electromagnetic valve, a liquid storage device and a compressor, wherein the inlet ends of the front evaporator and the rear evaporator communicate with the liquid storage device through pipelines, the outlet ends of the front evaporator and the rear evaporator communicate with the compressor through pipelines, and the electromagnetic valve is arranged on the pipeline between the liquid storage device and the rear evaporator. Thepipeline where the front evaporator is located and the pipeline where the rear evaporator is located form a parallel pipeline. The double-evaporator air conditioning system further comprises a frontexpansion valve and a rear expansion valve, wherein the rear expansion valve is arranged on the pipeline between the liquid storage device and the rear evaporator, and the front expansion valve is arranged on the pipeline between the liquid storage device and the front evaporator. The rear expansion valve is arranged between the electromagnetic valve and the rear evaporator on the pipeline betweenthe liquid storage device and the rear evaporator. The invention further discloses a matching method of the double-evaporator air conditioning system. The method comprises the steps that the volume Vin the pipeline between a three-way valve and the electromagnetic valve is calculated, and the position where the electromagnetic valve is located is calculated according to the volume V in the pipeline under the condition that the cross sectional area of the pipeline is known.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioning, and in particular relates to a double evaporator air conditioning system and a matching method thereof. Background technique [0002] With the rapid development of the automobile industry, the automotive air-conditioning industry is also rapidly improving. Human beings have continuously improved the comfort in the car, and the importance of automotive air-conditioning as a system to improve occupant comfort is becoming more and more prominent. At present, the introduction of dual evaporator air-conditioning systems in high-end passenger cars, large SUVs, and MPVs has become an important means to improve the comfort of middle and rear passengers. Compared with the traditional single evaporator air conditioning system, the double evaporator air-conditioning system has certain problems in terms of system matching and system stability. Balance and so on become the key and difficu...
