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:

空調是遠距離無(wú)法使坐墊方向盤(pán)上的溫度疾速降低,而汽車(chē)降溫劑是近距離的,離物體表面5-10CM噴射,主要成分是干冰,噴射后汽化,物理里學(xué)過(guò):汽化吸熱,可帶走物體表面的熱量,然后抵達降溫的效果.車(chē)內高溫,因為車(chē)廂內面積小,空氣不流通,致使車(chē)內的負離子降低到很低,會(huì )使人感覺(jué)到疲乏,頭暈,嚴重還可致使昏厥.

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、混凝土攪拌車(chē)風(fēng)口向上操控溫差

1. Temperature difference control of concrete mixer with tuyere upward

攪拌車(chē),混凝土攪拌車(chē)空調溫度不要調得太低,風(fēng)速不要太校自動(dòng)恒溫空調一般車(chē)廂表里溫差不要逾越10℃。非恒溫式空調,可先把涼氣溫度設在低,風(fēng)速開(kāi)到大,等覺(jué)得冷時(shí)再把溫度調高一點(diǎn),把風(fēng)速降一擋,如還冷,再將溫度調高些,然后將風(fēng)速降下來(lái),重復這么才是準確操作。當攪拌車(chē),混凝土攪拌車(chē)外溫度抵達30℃以上時(shí),應把攪拌車(chē),混凝土攪拌車(chē)內溫度操控到25℃擺布。

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、混凝土攪拌車(chē)到目的地先關(guān)空調

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

攪拌車(chē),混凝土攪拌車(chē)在抵達目的地前三五分鐘關(guān)掉空調,不只可以降低油耗,更能防止空調發(fā)作異味。在攪拌車(chē),混凝土攪拌車(chē)泊車(chē)前幾分鐘關(guān)掉空調,一同恰當加大風(fēng)量,在攪拌車(chē),混凝土攪拌車(chē)泊車(chē)前使空調管道內的溫度上升,就可以減少冷凝水的發(fā)作而堅持攪拌車(chē),混凝土攪拌車(chē)空調系統的相對干燥,霉菌天然也就沒(méi)有了生計的空間。

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.

降溫劑實(shí)際上便是干冰，霎時(shí)間蒸發(fā)后便是CO2，只需不是許多運用（CO2濃度太高對人體仍是有害的），可以起到降溫效果。

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、先開(kāi)攪拌車(chē),混凝土攪拌車(chē)空調外循環(huán)

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

天熱了,烈日下攪拌車(chē),混凝土攪拌車(chē)內溫度也許高達攝氏六七十度,這時(shí)上攪拌車(chē),混凝土攪拌車(chē)前應先把車(chē)門(mén)、車(chē)窗翻開(kāi),開(kāi)釋積聚在車(chē)內的熱氣,且不要急于關(guān)上車(chē)窗,先翻開(kāi)攪拌車(chē),混凝土攪拌車(chē)空調外循環(huán),待車(chē)廂表里溫度鄰近時(shí),關(guān)閉車(chē)窗,啟用內循環(huán)。待攪拌車(chē),混凝土攪拌車(chē)內溫度抵達正常舒暢狀態(tài)時(shí),當即關(guān)閉風(fēng)門(mén),抵達疾速降溫效果。

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、混凝土攪拌車(chē)堵車(chē)時(shí)翻開(kāi)車(chē)窗

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

長(cháng)時(shí)間運用空調會(huì )使攪拌車(chē),混凝土攪拌車(chē)冷凝器壓力過(guò)大,這不只會(huì )對攪拌車(chē),混凝土攪拌車(chē)制冷系統構成損耗,而且也會(huì )降低攪拌車(chē),混凝土攪拌車(chē)空調的制冷效果。所以,在攪拌車(chē),混凝土攪拌車(chē)內溫度現已讓您熱氣頓消的時(shí)分,不妨將空調關(guān)閉一會(huì )兒。

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.

“汽車(chē)降溫劑”那是指冷卻發(fā)動(dòng)機溫度的，叫做“防凍液”是專(zhuān)門(mén)對發(fā)動(dòng)機溫度進(jìn)行冷卻的，對于汽車(chē)內部或許房子的室內沒(méi)用效果的。汽車(chē)降溫劑可以靈敏降溫,如今世面上有許多汽車(chē)降溫劑,成分是干冰,對人體都是無(wú)害的,但有些是添加了芳香劑,讓人愈加難過(guò),盡量挑選無(wú)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

車(chē)內的溫度難降也許是空調欠好，或許車(chē)的密封欠好；汽車(chē)降溫運用空調，不用降溫劑，制冷原理和家用空調相同；車(chē)內溫度高，除了人比照難過(guò)以外便是車(chē)內的裝飾資料老化快。

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.
