Concrete mixer trucks and engineering vehicles cooling methods

The car temperature is difficult to drop may be bad air-conditioning, or car seal is not good; car cooling using air conditioning, no cooling agent, the principle of 
refrigeration and home air-conditioning as high temperature inside the car, in addition to people more uncomfortable outside the car Decoration materials aging fast. The 
principle of cooling agents in general, are absorbed through the liquid vapor to heat. Another is through the liquid into a liquid to absorb heat.Not seen you say, I guess is a 
solid into a liquid to cool the From the microscopic point of view, is outside the temperature or pressure changes in the material inside the distance between the molecules become larger, is the need for energy, generally reflected in the absorption of heat from the environment to reduce the temperature in the environment. 

1, concrete mixer turck tuyere up to control the temperature mixer, concrete mixer air conditioning temperature is not too low, the wind speed is not too automatic thermostatic 
air conditioning inside and outside the general compartment temperature should not exceed 10 ℃. Non-constant temperature air-conditioning, air temperature can be set at the 
lowest, the wind to open to the maximum, so that when the cold then the temperature increase that the wind down a block, such as cold, then the temperature increase, and then   
wind Down, repeated this is the correct operation. When the mixer, concrete mixer temperature of 30 ℃ or more, should the mixer, concrete mixer temperature control to 25 ℃ or 
so. 

2, mixer, concrete mixer to the destination first off air conditioning 
Mixer, concrete mixer in the first 35 minutes to reach the destination turn off the air conditioning, not only can reduce fuel consumption, better avoid air conditioning odor. 
In the mixer, concrete mixer parking a few minutes before turning off the air conditioning, while appropriate increase the amount of air in the mixer, concrete mixer parking 
before the air conditioning pipe temperature rise, you can reduce the generation of condensate and keep the mixer, Concrete mixer air conditioning system is relatively dry, mold 
naturally there is no room for survival. 
You say that the car coolant inside the car, right? Cooling agent is actually dry ice, instant evaporation is CO2, as long as not a lot of use (CO2 concentration is too high on 
the human body or harmful), can play a cooling effect. 

3, the first open mixer, concrete mixer air conditioning external circulation 
Hot days, under the hot sun mixer, concrete mixer temperature may be as high as sixty or seventy degrees Celsius, this time on the mixer, concrete mixer should be the first 
before the doors, windows open, release the accumulation of heat in the car, and Do not rush to close the window, first open the mixer, concrete mixer air conditioning external 
circulation, when the temperature inside and outside the car is similar to close the window, enable the inner loop. To be mixer, concrete mixer temperature to reach the normal 
state of comfort, immediately close the damper to achieve rapid cooling effect. 

4, mixer, concrete mixer truck open the window when the traffic jam 
Long-term use of air-conditioning will make the mixer, concrete mixer condenser pressure is too large, which will not only mixers, concrete mixer refrigeration system caused 
losses, but also reduce the mixer, concrete mixer air conditioning cooling effect. Therefore, in the mixer, the temperature of the concrete mixer has let you heat Dun Dun, may 
wish to turn off the air conditioning for a while. 

Air conditioning is a long distance can not make the cushion on the steering wheel temperature dropped rapidly, and automotive cooling agent is close, from the surface 5-10CM 
jet, the main ingredient is dry ice, spray vaporization, physics, learned: vaporization endothermic, can The body surface heat, so as to achieve the cooling effect.Car high 
temperature, due to the compartment area is small, the air does not flow, leading to the car negative ions dropped to very low, will make people feel tired, dizziness, serious 
can lead to Syncope. 

Car cooling agent can quickly cool down, and now the world there are a lot of automotive cooling agent, the composition of dry ice, the human body is harmless, but some are 
added fragrance, people more uncomfortable, the best choice for tasteless, environmental health! You can rest assured that use.
