2 Types of car refrigerator
On the market, car refrigerators are mainly divided into two categories.
The first category: semiconductor car refrigerator//thermoelectric coolers
The second category: compressor car 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.
Compressor car refrigerator
As the hub of the refrigeration system, the compressor of the fridge 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.
Advantages and Disadvantages
Advantages of Semiconductor Refrigerators
Lower power consumption: Semiconductor refrigerators require less power than compressor refrigerators, making them more energy-efficient.
Noiseless operation: Semiconductor refrigerators do not have moving parts, so they operate silently.
Compact size: Semiconductor refrigerators are smaller and more compact than compressor refrigerators, making them suitable for use in small spaces.
Lower maintenance requirements: Semiconductor refrigerators have fewer parts that can break down, so they require less maintenance than compressor refrigerators.
Disadvantages of Semiconductor Refrigerators
Limited cooling capacity: Semiconductor refrigerators are not as efficient as compressor refrigerators and have a limited cooling capacity, so they may not be suitable for cooling larger items.
Limited temperature range: Semiconductor refrigerators are designed to cool items to a specific temperature range, and they may not be suitable for cooling items that require a wider temperature range.
Longer cooling time: Semiconductor refrigerators take longer to cool items than compressor refrigerators, so they may not be suitable for items that require rapid cooling.
