Generally speaking, the principle of cooling agent is to absorb heat by liquid evaporation. Another is to absorb heat by changing a solid into a liquid. I guess it's a solid into a liquid to cool down. From the microscopic point of view, it's the change of external temperature or pressure that makes the distance between molecules in the material larger, which requires energy, Today, the general body absorbs heat from the environment, and the temperature in the environment has been reduced. Now let's take a look at the cooling tips introduced by the mobile concrete mixer manufacturer:

空调是远距离无法使坐垫方向盘上的温度疾速降低,而汽车降温剂是近距离的,离物体表面5-10CM喷射,主要成分是干冰,喷射后汽化,物理里学过:汽化吸热,可带走物体表面的热量,然后抵达降温的效果.车内高温,因为车厢内面积小,空气不流通,致使车内的负离子降低到很低,会使人感觉到疲乏,头晕,严重还可致使昏厥.

The air conditioner can't make the temperature on the cushion and steering wheel drop rapidly in a long distance, while the car cooling agent is sprayed 5-10cm away from the surface of the object. The main component is dry ice, which vaporizes after spraying. I learned in Physics: vaporization absorbs heat, which can take away the heat from the surface of the object, and then reach the cooling effect. The high temperature in the car, because of the small area in the car and the lack of air circulation, reduces the negative ions in the car to a very low level, Can make a person feel tired, dizzy, serious still can cause fainting

1、混凝土搅拌车风口向上操控温差

1. Temperature difference control of concrete mixer with tuyere upward

搅拌车,混凝土搅拌车空调温度不要调得太低,风速不要太校自动恒温空调一般车厢表里温差不要逾越10℃。非恒温式空调,可先把凉气温度设在低,风速开到大,等觉得冷时再把温度调高一点,把风速降一挡,如还冷,再将温度调高些,然后将风速降下来,重复这么才是准确操作。当搅拌车,混凝土搅拌车外温度抵达30℃以上时,应把搅拌车,混凝土搅拌车内温度操控到25℃摆布。

The air conditioning temperature of mixer truck and concrete mixer truck should not be adjusted too low, the wind speed should not be too high, and the temperature difference between the surface and inside of the car should not exceed 10 ℃. For non constant temperature air conditioning, you can first set the temperature of the cool air at a low level and turn on the wind speed to a high level. When you feel cold, you can turn up the temperature a little and turn down the wind speed. If it is still cold, you can turn up the temperature a little and then turn down the wind speed. When the temperature outside the mixer and concrete mixer reaches above 30 ℃, the temperature inside the mixer and concrete mixer should be controlled to 25 ℃.

2、混凝土搅拌车到目的地先关空调

2. Turn off the air conditioning before the concrete mixer arrives at the destination

搅拌车,混凝土搅拌车在抵达目的地前三五分钟关掉空调,不只可以降低油耗,更能防止空调发作异味。在搅拌车,混凝土搅拌车泊车前几分钟关掉空调,一同恰当加大风量,在搅拌车,混凝土搅拌车泊车前使空调管道内的温度上升,就可以减少冷凝水的发作而坚持搅拌车,混凝土搅拌车空调系统的相对干燥,霉菌天然也就没有了生计的空间。

Turn off the air conditioner three or five minutes before arriving at the destination. It can not only reduce the fuel consumption, but also prevent the air conditioner from smelling. Turn off the air conditioner a few minutes before parking the mixer and the concrete mixer, and increase the air volume properly. Before parking the mixer and the concrete mixer, increase the temperature in the air conditioning pipe, so as to reduce the occurrence of condensation water. If we insist on the relatively dry air conditioning system of the mixer and the concrete mixer, there will be no living space for mold.

降温剂实际上便是干冰，霎时间蒸发后便是CO2，只需不是许多运用（CO2浓度太高对人体仍是有害的），可以起到降温效果。

The cooling agent is actually dry ice, which evaporates in a flash and then becomes CO2. It only needs a lot of application (too high CO2 concentration is still harmful to human body), which can play a cooling effect.
                    

3、先开搅拌车,混凝土搅拌车空调外循环

3. Start mixing truck first, concrete mixing truck air conditioning external circulation

天热了,烈日下搅拌车,混凝土搅拌车内温度也许高达摄氏六七十度,这时上搅拌车,混凝土搅拌车前应先把车门、车窗翻开,开释积聚在车内的热气,且不要急于关上车窗,先翻开搅拌车,混凝土搅拌车空调外循环,待车厢表里温度邻近时,关闭车窗,启用内循环。待搅拌车,混凝土搅拌车内温度抵达正常舒畅状态时,当即关闭风门,抵达疾速降温效果。

When it's hot, the temperature in the concrete mixer may be as high as 60 ℃ or 70 ℃ in the hot sun. When you get on the mixer, you should open the door and window first to release the heat accumulated in the car, and don't rush to close the window. Turn on the mixer first, and the air conditioner of the concrete mixer will circulate externally. When the temperature inside and outside the car is close, close the window and start the internal circulation. When the temperature in the mixer truck and concrete mixer truck reaches the normal and comfortable state, close the damper immediately to achieve the effect of rapid cooling.

4、混凝土搅拌车堵车时翻开车窗

4. Open the window of concrete mixer truck in traffic jam

长时间运用空调会使搅拌车,混凝土搅拌车冷凝器压力过大,这不只会对搅拌车,混凝土搅拌车制冷系统构成损耗,而且也会降低搅拌车,混凝土搅拌车空调的制冷效果。所以,在搅拌车,混凝土搅拌车内温度现已让您热气顿消的时分,不妨将空调关闭一会儿。

Long time use of air conditioning will make the mixer and concrete mixer condenser pressure too high, which will not only cause loss to the mixer and concrete mixer refrigeration system, but also reduce the refrigeration effect of mixer and concrete mixer air conditioning. Therefore, in the mixer, the temperature in the concrete mixer is now let you heat up, you might as well turn off the air conditioner for a while.

“汽车降温剂”那是指冷却发动机温度的，叫做“防冻液”是专门对发动机温度进行冷却的，对于汽车内部或许房子的室内没用效果的。汽车降温剂可以灵敏降温,如今世面上有许多汽车降温剂,成分是干冰,对人体都是无害的,但有些是添加了芳香剂,让人愈加难过,尽量挑选无味的,健康!可以放心使用.

"Car cooling agent" refers to the cooling of the engine temperature, called "antifreeze". It is specially used to cool the engine temperature, which has no effect on the interior of the car or the house. Car cooling agent can be sensitive to cool down, now there are many car cooling agents in the world, the composition is dry ice, which is harmless to the human body, but some are added with aromatic agent, which makes people more sad, try to choose tasteless, environmental protection and health! It can be used safely

车内的温度难降也许是空调欠好，或许车的密封欠好；汽车降温运用空调，不用降温剂，制冷原理和家用空调相同；车内温度高，除了人比照难过以外便是车内的装饰资料老化快。

The temperature inside the car is difficult to drop. Maybe the air conditioning is not good, maybe the car seal is not good; Air conditioning is used to cool the car without cooling agent. The refrigeration principle is the same as that of household air conditioning; The temperature inside the car is high. In addition to people's sadness, the decoration materials inside the car are aging quickly.
