What does 'cold' mean in a car refrigerator?
2 Answers
In a car refrigerator, 'cold' refers to the cooling switch. A car refrigerator is a portable cooler that can be carried in a vehicle. There are mainly two types of car refrigerators on the market: one is a semiconductor car refrigerator, which operates on the principle of electronic chip cooling. The other is a compressor car refrigerator, which uses traditional compressor technology for cooling and can achieve lower temperatures. Below is more detailed information about car refrigerators: 1. Compressor car refrigerator: This type can reach temperatures as low as -18°C to 10°C, has high cooling efficiency, can make ice and preserve freshness, and is larger in size. It represents the future trend of car refrigerators. 2. Semiconductor car refrigerator: The advantages of this type include both cooling and heating capabilities, environmental friendliness, no pollution, compact size, lower cost, vibration-free and noiseless operation, and long lifespan. However, its cooling performance is affected by ambient temperature, cannot reach below freezing, and has a smaller capacity.
I often go on road trips and have gotten used to using a car fridge. The 'cold' button refers to the strongest cooling setting, which can lower the temperature to the lowest point—especially useful during hot summers. For example, if you put some drinks inside, they can cool down in just a few minutes. However, be careful not to keep it on max all the time, as the fridge will consume power quickly and the car battery might not handle it. Also, remember to turn it off when the engine is off to avoid draining the battery and preventing the car from starting. Some fridges have a temperature adjustment knob, where 'cold' usually means turning it all the way to the left or pressing a dedicated button. I've tried several brands, and they all work similarly. Overall, it's a great helper for quick cooling, especially during long trips.
