There are many types of water dispensers, which can be divided into commercial water dispensers and household water dispensers according to their uses, and there are different types of control methods, cooling methods, and drinking water temperatures.
1. Classification by shape
Water dispensers can be divided into two types: desktop and vertical (or floor-standing). Desktop water dispensers generally do not have disinfection cabinets or lockers, so they are smaller in size and more convenient to move. The upper part of the vertical water dispenser is a water dispenser, and the lower part is a disinfection cabinet or locker, which can sterilize tea sets or store fresh food. Some models are also equipped with a small freezer for frozen beverages.
2. Classification by drinking water temperature
It can be divided into three types: warm type, cold-heat type, and three-temperature type. The warm water dispenser is equipped with normal temperature/hot water taps, which supply normal temperature water with 88-96 degrees Celsius hot water respectively. This model is equipped with a cold/hot water faucet, which supplies cold water at 5-12 degrees Celsius and hot water at 88-96 degrees Celsius respectively. The three-temperature water dispenser integrates the functions of the above two models, and is equipped with three taps to supply normal temperature water, cold water and hot water respectively.
3. Classification by cooling method
It can be divided into two types: electronic refrigeration type and compressor refrigeration type, and each type is divided into desktop and vertical water dispensers. Electronic refrigeration water dispenser adopts semiconductor components for refrigeration, also known as semiconductor refrigeration water dispenser. It has the characteristics of low power consumption, low operating noise, no pollution, automatic control and low price.
The disadvantage is that the cooling speed is slow and the amount of cold water supplied is small, which is suitable for families and units with a small number of drinking water. The refrigeration principle of the compressor refrigerated water dispenser is the same as that of the refrigerator. The difference is that the evaporator is wrapped around the stainless steel water tank wall and absorbs heat to cool the water. The refrigeration capacity is about 3L, and the refrigeration power is between 75-110W. It has the characteristics of high performance, high cooling efficiency, fast cooling speed, and large supply of cold water. Its cooling performance is obviously better than that of electronic cooling water dispensers, but the price is more expensive.
