The heat is unbearable, and the car air conditioner is turned on like this to quickly cool down
It is the dog days right now. As the saying goes: "Small summer heat catches the big heat, so there is nowhere to hide." If the outdoor in summer is like a stove, then the car can definitely be regarded as an "alchemy stove". Almost all car owners and friends get on the car first thing is to drive! air! Tune! But do you really know about car air conditioners? Today we will have a chat~
Development History
In 1927, people used car engine cooling water as a heat source to realize the concept of car air conditioning, but it could only achieve a single heating function, not cooling.
In the mid-nineteenth century, American automobile companies took the lead to install integrated heating and cooling air conditioners on their own models, allowing automobile air conditioners to basically have a series of basic air conditioning functions.
With the continuous development of the automotive industry, the functions of automotive air conditioners are constantly improving. Today's car air conditioners consist of the following components:
working principle
The principle of automobile air conditioners is roughly the same as that of general air conditioners. They all use compressors for cooling. In daily driving, when the A/C button on the center console of the vehicle is lit, it means that the car compressor is working. At the same time, the car compressor is driven by the engine, so when the A/C is lit Fuel consumption will increase accordingly. When heating, the car air conditioner does not pass through the compressor, but uses the engine cooling water to flow through the heater into the cabin. This is also the reason why automobile air conditioning does not consume fuel for heating.
Cool tips
Is there any way to cool the car quickly in summer?
1. With the continuous progress of the automotive industry, some vehicles already have the remote start function, which can be used to remotely start the vehicle and turn on the air conditioner in advance to solve this trouble.
2. It doesn’t matter if you don’t have this function. After entering the vehicle, we can first open the passenger window/door, and then repeatedly open and close the cab door ten times to fan the outside air into the vehicle to replace the hot air gathered in the vehicle. Cooling purpose.
3. Don't turn on the air conditioner immediately when the temperature in the car is high, it is not only difficult to cool down quickly. At the same time, it will increase the engine load, causing damage in the long run. The hot air accumulated in the car should be released first, and then the air conditioner should be turned on when the temperature inside and outside the car approaches. (Do not turn on the hot air conditioner directly when entering the vehicle in winter. You should wait for the water temperature of the cooling water tank to reach a stable water temperature before turning it on.)
4. After entering the car, the air outlet of the car air conditioner can be upwards. Since the density of hot air is lower than that of cold air, we can use this physical characteristic to improve the cycle efficiency, thereby improving the cooling efficiency and accelerating the cooling of the car.
new energy vehicles
New energy vehicles use electric drive motors. Although the principle of cooling is the same as that of fuel vehicles, they do not have as much waste heat energy as fuel vehicles in the case of heating. The general mainstream method is to use PTC thermal Resistor heating is simply the use of battery energy for heating or cooling. Therefore, unlike fuel vehicles for heating, new energy vehicles consume a large amount of electrical energy and reduce the mileage.
