Automobile air-conditioning system with double evaporators and control method of automobile air-conditioning system

Abstract

The invention provides an independently controllable automobile air-conditioning system with double evaporators and a control method of the automobile air-conditioning system. Energy conservation and emission reduction are realized while automobile internal comfort is guaranteed, and good economic benefit is realized. The automobile air-conditioning system with the double evaporators comprises a compressor, a condenser, a liquid storage dryer and an air-conditioning controller, the compressor, the condenser and the liquid storage dryer are successively serially connected via a pipeline, the liquid storage dryer is connected with two branches via two branched pipelines, one of the two branches is connected with a front electromagnetic valve, a front expansion valve and a front evaporator, the other branch is connected with a rear electromagnetic valve, a rear expansion valve and a rear evaporator, the front evaporator and the rear evaporator are connected with the compressor via a pressure balance device, and the front electromagnetic valve, the rear electromagnetic valve and the compressor are controlled by the air-conditioning controller. The air-conditioning system comprises the two evaporators, is high in refrigerating output and fast in cooling, can keep fine automobile internal comfort, saves energy and has good economic benefit. Operation of the two evaporators is controlled independently.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning, and in particular relates to an independently controllable automobile double-evaporator air-conditioning system suitable for large MPV vehicles and a control method thereof. Background technique [0002] As an important means of transportation for long-distance journeys, commercial vehicles are deeply loved by consumers, and commercial vehicles also have high requirements for the comfort of the vehicle, especially in hot summer and cold winter, which require higher performance of the air conditioning system. Large commercial vehicles are generally equipped with three or more rows of seats. Traditional air conditioners are generally arranged under the instrument panel. Due to the limitation of air volume and cooling capacity, it is difficult to ensure the comfort of rear passengers. Although the air volume and cooling capacity of the air conditioner can be increased, it is st...

AI Technical Summary

Problems solved by technology

Large commercial vehicles are generally equipped with three or more rows of seats. Traditional air conditioners are generally arranged under the instrument panel. Due to the limitation of air volume and cooling capacity, it is difficult to ensure the comfort of rear passengers.

Although the air volume and cooling capacity of the air conditioner can be increased, it is still difficult to balance the temperature and wind speed of the front and rear rows because of the long distance between the front and rear rows, so it is difficult to make the passengers in the front and rear rows feel comfortable at the same time
