[dongxing Refrigeration] cold water machine type selection skills
正文：
     There are many plastic products factory, or to the circulating water chiller machine or oil cooled friends, in the purchase of industrial cooling water machine, usually do not know what type of cold water machine, the refrigeration effect to achieve their own standard, or do not know what kind of machine is more suitable for their own production workshop.East Star tell you some simple selection method. Hope to bring help to the needs of the people.
     First of all, we have to know what kind of ice machine is divided into several types: the general manufacturers, will produce two kinds of water cooling and air cooling.
     Air cooled chiller, in its body containing a thermal insulation water tank and a water pump, without adding another cooling water tower to heat. Installation and movement is very convenient. But it requires a higher working environment, first, because it is a hot air cycle to refrigeration, so if the installation of the ventilation effect of the workshop is not good, it will directly affect the cooling effect of the water chiller. In addition, if you want to put the cold water machine in a clean room with humidity requirements, then I advise you to be modified. Because the air-cooled chiller, will be in the top spray water vapor to heat.
     Water cooled chiller, and can be divided into open, sealed type (some known as box type) and screw type. First of all make it clear, cold water machine, water cooled, to add cooling water tower and water pump, hot water to extract heat. In order to achieve a good effect of cooling effect.Open type of cold water machine, but also to install a water tank, the seal is not necessary, because he has built a water tank. Open general will be installed in the workshop somewhere, he convenient maintenance, but because is not beautiful, therefore it has a sealed water cooling type cold water machine, because it is a structure of the box, so popular. But if you require a very large amount of refrigeration, then we must choose the screw type of cold water machine, then we generally call it the cold water unit
