Automobile air conditioning system

Abstract

The technical scheme of the invention relates to an automobile air conditioning system. The automobile air conditioning system is characterized by comprising an air inlet channel which is arranged on the top of an automobile body and extends along a front-and-after direction of the automobile body, air outlet channels which are arranged on the left side and the right side of the air inlet channel respectively, wet curtains blocked between the air inlet channel and the air outlet channels, fans which are arranged at the entrances of the air outlet channels and used for extracting air from the air inlet channel to the air outlet channels, water distribution pipelines which are arranged on the top or lateral parts of the wet curtains and used for distributing water on the wet curtains, and a water supply device connected with the water distribution pipelines to supply water, wherein an air inlet for communicating the air inlet channel with air outside the automobile body is formed on the top of the automobile body; and air outlets for communicating the air outlet channels with air in a carriage are formed on the top or the lateral parts of the carriage. The automobile air conditioning system realizes temperature reduction by adopting a water evaporation effect theory and using a physical method; and the automobile air conditioning system is a complete coolant-free, heat pollution-free, energy-saving and environment-friendly automobile air conditioner.

Description

technical field [0001] The invention relates to an automobile air-conditioning system, which is applicable to automobiles such as buses and passenger cars. Background technique [0002] The air-conditioning systems of urban public transport vehicles commonly used at present have the following characteristics: [0003] (1) Although many urban traffic control departments have stipulated whether the bus is air-conditioned or not, it is subject to the weather forecast of the day. As long as the maximum temperature reaches 28°C, the bus must be air-conditioned, but many buses consider energy consumption. It is stipulated that the air conditioner should be turned on from June 1st to October 30th every year. When the air conditioning facility is not in use, only the vehicle ventilation facility should be turned on. In this way, whether to turn on the air conditioner cannot be adjusted according to the actual temperature. Even if the weather is very hot in spring and autumn, the ai...

AI Technical Summary

Problems solved by technology

Even if the air conditioner of the new car works well, after two or three years, due to the high mileage of the bus every year, there are common problems such as aging lines, damaged air conditioners, and insufficient horsepower after the air conditioner is turned on.

In addition, since the unit of the top-mounted air conditioner is exposed to the outside, the long-term wind and sun will easily cause the aging of the air-conditioning components, and also affect the appearance of the vehicle

[0005] Therefore, the current design of the air-conditioning system for urban cars is not ideal, and there are many problems that need to be solved urgently: such as poor cooling effect, slow cooling, flameout when starting, difficult acceleration, insufficient power when climbing, and fuel consumption when the air conditioner is running. Big and so on

[0007] (4) At the turn of spring and summer, many bus companies did not regularly clean and disinfect the carriages, and did not clean and maintain the air-conditioning system

As a result, the air in the compartment is dirty and the air quality in the compartment is poor, which is conducive to the growth of bacteria

When the temperature outside the car is high and the humidity is low, the air conditioner plays a role in cooling down the temperature to a certain extent. However, when the air conditioner is turned on, due to the consideration of the cooling effect, the windows are closed tightly, and the CO and CO in the car 2 , formaldehyde concentration is much higher than outside, the air quality inside the car is very poor, affecting the normal circulation of air, the dirty air in the car circulates repeatedly, compared with the car without air conditioning, the air quality is much worse, easy to breed bacteria, easy to infect disease spread

Therefore, the function of the air conditioner in the car is only to improve thermal comfort, not to improve the air quality, but to deteriorate the air quality due to airtightness

[0008] (5) The temperature of the existing urban car air-conditioning system is regulated by the driver according to the actual situation in the car and the opinions of the passengers. Many drivers said that there are regulations on the need to turn on the air conditioner when the temperature is higher than a certain value, but in the end it is adjusted to There is no fixed value for how many degrees are appropriate

However, the synthesis process of HFC-R134a is more complicated and the production cost is higher
