Method for judging structure type of industrial cold water machine special for Industry
Recently, Shenzhen is the last few days of heavy rain, but still can not withstand the sales boom of industrial cold water machine. However, the East Star in the process of communication with each user, we found that the structure and type of industrial cold water machine is not very understanding, so it is easy to cause misunderstanding so that the unit can not match the use of. Therefore, the East Star cold water machine factory decided to compare the popular terms of the words to introduce.
First, we divide the type of industrial chiller. There are two main types: air-cooled chiller and water cooled chiller, the difference of which lies in the different heat dissipation methods. Air cooling water machine is used to install the fan and air exchange to achieve cooling, water cooling machine is the need for auxiliary equipment - cooling tower, water pump to heat. The most simple identification method is: cold water machine on the top or side of the installation of the fan, is the air-cooled chiller. There is water cooled chillers with round yellow water tower.
Now, let's talk about the structure of the industrial cold water machine. Under normal circumstances, we are divided into box type cold water machine (also known as the seal type cold water machine) and the open type cold water machine. Box type cold water machine, as its name implies, is an outer box, all of the units are fixed in the chassis installed inside, to prevent dust and other debris into the components affect the performance of cold water machine. Open type cold water machine is an open structure, there is no outside box, all the components are exposed in the configuration, we can refer to the back of the picture can be understood.
In addition, the East stars remind you: if your factory used cold water machine, need to be replaced or added, can directly to the cold water machine models tell us, and confirm what kind of cold water machine, what kind of structure. In addition, but also to confirm that your factory has a ready-made pool or tank, if there is, then the practice of cold water machine evaporator is not the same. In order to save time, reduce waste, you can find the use of more understanding of communication, to ensure that the correct selection.
Analysis of the advantages of special industrial chiller heat exchanger
For food, chemical industry, metallurgy, construction industry air-cooled chiller / common water cooling machine can be used for plate heat exchanger. But in the early 70s appeared in the heat exchanger, it has the characteristics of compact structure, small volume, strong and low cost, is mainly composed of dozens or even hundreds of pieces with concavo convex lines of stainless steel or other metal plates. Between the adjacent heat exchanger used in industrial chillers of different lines, uneven, to ensure that the cross flow of the two fluid flow diversion, and the formation of many points of contact, the contact point of all vacuum welding, will become a good heat transfer and compact heat exchanger.
And the traditional heat exchanger compared when used in condenser and evaporator, the size and the weight of the plate heat exchanger is a traditional tube 1/6. Therefore, the plate heat exchanger is generally made of stainless steel material, and a brazing in vacuum under high, so it has high strength. The main advantages are as follows: 1, the volume is small, the weight is light. When used with the chiller condenser or evaporator, plate type heat exchanger is the traditional heat exchanger volume and weight of 1/6 to 1/5; 2, high working pressure. Except for the edge of plate heat exchanger, where bump contact between plate are welded, so a lot of solder joints of high strength, high pressure resistance, heat exchanger, some of the company's allowable working pressure is 3MPa; 3, the demand for small refrigerant. The heat exchanger has the advantages of small volume, so the demand for small refrigerant. Some of the plate heat exchanger refrigerant demand only the traditional shell and tube type 1/4; 4, easy to freeze. The concave convex pattern of complex heat exchanger, cooling water flow height disorder, not easy to freeze. Even if there are local icing, also can use. As compared with the traditional heat exchanger shell and tube heat exchanger can withstand due to freezing pressure; 5, unit of. Parallel plate heat exchanger easy combination, in order to adapt to the requirements of heat exchanger. At present, according to the different type of cold water machine, evaporator, condenser types used are not the same, these can be in accordance with the different industries or user needs to choose. In addition, the East Star cold water machine shell and tube evaporator / condenser, evaporator coil, fin condenser are independent design and production, good quality, good effect, cold enough.
