Truck drivers are on the road all year round, especially in winter and summer, when they have to face the challenges brought by extremely hot and cold climates. This summer is here, and a new round of hot challenges is about to begin. Some summer driving equipment should be supplemented in advance.
As a continuation of home refrigerators, car refrigerators are a new generation of refrigeration and refrigeration appliances that have been popular in the market in recent years. They can store drinking water and food. Imagine that when you are impatient waiting in a traffic jam or stopping for a rest, a bottle of iced soda or even a piece of iced watermelon must be a great cool feeling. Car refrigerators can bring you a touch of coolness in the hot summer.
●Current situation of car refrigerator use
Large cab space, easy installation in Europe and the United States
In North America, the paradise of long-head trucks, the spacious cab can carry various electrical equipment for daily use, and a small car refrigerator can be easily arranged in the cab. It's so comfortable to eat some fruit and drink some drinks while resting in the car.
Flat-floor cabs are more common in Europe. Cabs are tall and large, so car refrigerators can be placed on the upper part of the cab to store drinking water, etc., and do not occupy the bottom space.
There are also configurations in China, and we look forward to progress and development
Domestic trucks are still mainly flat-head trucks, and the space inside the cab is limited. Even if you want to install it, there is not much space. The editor remembers that several manufacturers have also equipped vehicles with on-board refrigerators. The humanized concept is still relatively advanced, but for some reason, this configuration has not been carried forward. Although high-end models are developing rapidly and constantly improving in humanized design, on-board refrigerators are still relatively rare. If user demand increases, it will definitely not be difficult for manufacturers to install on-board refrigerators.
● On-board refrigerators are divided into two categories, and there are many varieties on the market
At present, if truck drivers want to use car refrigerators, they almost all buy them on the market. There are many types of car refrigerators on the market, with different capacities and shapes, but they can be divided into semiconductor type and compressor type car refrigerators according to the refrigeration method. The price of car refrigerators ranges from a few hundred yuan to a few thousand yuan. Semiconductor car refrigerators are cheap, while compressor refrigerators are relatively expensive.
Semiconductor refrigerators are small and environmentally friendly, but the working environment is easily affected
The principle of semiconductor car refrigerators is to rely on electronic chips for refrigeration, and use the P-N junction composed of special semiconductor materials to form a thermocouple pair to produce the Peltier effect, that is, a new type of refrigeration method using DC refrigeration. In terms of refrigeration, it is generally 10~15 degrees lower than the ambient temperature, and its heating temperature can be as high as 65 degrees.
The advantages of this refrigerator are dual-purpose refrigeration and heating, environmental protection and pollution-free, small size, low cost, no vibration and noise during operation, and long life. The disadvantages are low refrigeration efficiency, refrigeration temperature is affected by ambient temperature, refrigeration cannot reach below zero, and small capacity.
Compressor refrigerators have strong refrigeration capacity and relatively high prices
Another type is compressor car refrigerators. Compressors are traditional technologies of traditional refrigerators, and the refrigeration temperature is low, at -18 degrees to -10 degrees. High refrigeration efficiency, ice making and preservation, and large size are the mainstream direction of future car refrigerator development. However, this refrigerator is bulky, inconvenient to carry, and expensive. The compressors of car refrigerators are mainly produced in Germany and Japan.
When purchasing, truck drivers should choose a car refrigerator with appropriate capacity according to the size of their cab space. If it is too small to hold too many things, and too big to have enough space to put them, you should also choose products with good quality and reputation in the dazzling market according to your needs and economic budget.
● Car refrigerators have high requirements and need to be purchased with caution
Car refrigerators are different from the static use environment of home refrigerators. The vehicle is always in a vibrating state during driving, and the power used by car refrigerators is all from the direct current of the vehicle, which makes the car refrigerator
