How To Choose A Car Fridge

So what are the functions, performance and classification of the car refrigerator, and how to choose a car refrigerator that meets your needs? Don't worry, let's analyze and compare from multiple dimensions.

The table of contents is as follows, you can choose the chapter you need.

First,. the classification and principle of car refrigerators

Second, Third, the purchase elements of car refrigerators

1. Product classification

On the current market, car refrigerators are mainly divided into two categories.

The first category: semiconductor car refrigerator

The second category: compressor car refrigerator

2. Working principle and advantages and disadvantages

Semiconductor refrigerator: refrigerating by electronic chips, using P-N junctions composed of special semiconductor materials to form thermocouple pairs to produce Peltier effect, which is a new type of refrigeration method through direct current refrigeration. The refrigeration temperature range is generally -5 to 65 degrees. It has the dual functions of cooling and heating, environmental protection, low vibration and noise. (From: Baidu Encyclopedia)

As the hub of the refrigeration system, the compressor sucks in low-temperature and low-pressure refrigerant gas from the suction pipe. After being compressed by the operation of the motor, the compressor discharges the high-temperature and high-pressure refrigerant gas to provide power for the entire refrigeration cycle. Realize the refrigeration cycle of compression, condensation, expansion and evaporation. The refrigeration temperature can generally reach -18 degrees and 10 degrees, the refrigeration efficiency is high, and the safety and ice making are both correct.

3.The purchase elements of car refrigerators

For semiconductor and compressor refrigerators, the comparative analysis from the dimensions of function, performance, space occupation, energy consumption, and price.
