Comparison Of Cooling Methods Of Car Refrigerators

    Electronic refrigeration is a refrigeration technology that utilizes the thermoelectric effect of semiconductor materials for refrigeration. Electronic refrigeration, also known as semiconductor refrigeration, or thermoelectric refrigeration, is a subject developed in the 1950s on the edge of refrigeration technology and semiconductor technology. It uses P-N junctions composed of special semiconductor materials to form thermocouple pairs and produce Pearl The tie effect, a new type of refrigeration method through direct current refrigeration, is known as the world's three major refrigeration methods together with compression refrigeration and absorption refrigeration.

    In the use of car refrigerators, which is better, electronic refrigeration or compressor refrigeration? By comparing these aspects, we can make our own choices and judgments.

   (1) Refrigeration method: Electronic refrigeration adopts electronic refrigeration sheet refrigeration, which has low noise and no pollution; compressor refrigeration adopts Freon refrigeration.

   (2) Refrigeration speed: The compressor has a faster cooling speed. When it is used for the first time or re-refrigerated, the temperature of the cold water drops below 15% after 30 minutes, and the re-refrigeration time is shorter. The compressor cooling time is about 20%-30% of the electronic cooling time.

   (3) Refrigeration effect: the lowest temperature of electronic refrigeration is 9-11℃, and the lowest temperature of compressor refrigeration is 5-6℃.

   (4) Service life: The service life of the electronic refrigeration sheet is generally five to eight years, and the service life of the compressor is generally ten to fifteen years.
