the electronic refrigeration water dispenser adopts semiconductor component refrigeration, also known as semiconductor refrigeration water dispenser, which has the characteristics of low power consumption, low running noise, no pollution, automatic control and low price. the lack of cooling speed is slow, the supply of cold water is less, suitable for families and units with small number of drinking water. the refrigeration principle of the condensing mechanism cold water dispenser is the same as that of the refrigerator. the difference is that the evaporator wraps around the wall of the stainless steel water tank and absorbs heat to cool down the water. the refrigeration capacity is about 3l, and the refrigeration power is between 75-110w. It has the characteristics of high reliability, high refrigeration efficiency, fast refrigeration speed and large supply of cold water. Its refrigeration performance is obviously better than that of the electronic refrigeration water dispenser, but it is sold It is more expensive and suitable for families and units with more drinking water.
