  What to do with the low-pressure alarm of the chiller? First, the low-pressure failure of the water chiller is due to the compressor suction pressure being too low. The compressor's normal suction pressure is 0.4~0.6MPa. When the suction pressure is lower than 0.2MPa, the low-pressure protection relay will act. If it is too low, the return air volume is lacking, and the cooling capacity cannot meet the requirements, which will cause unnecessary power loss. Therefore, the   water-cooled chiller factory   is here to talk about the six possible reasons for the low-pressure alarm: 1. Check whether the temperature of the cooling water is too low. When the outside temperature is too low, the cooling water is turned on and running at low temperatures; or the temperature of the refrigerating oil is too low, and the refrigerator cannot be completely separated, which will cause low-pressure failure. If the temperature of the cooling water is too low, shut down the cooling tower or throttle

  After many customers purchase the required  industrial water chiller , they often ignore some basic aspects of the refrigeration unit water pipe during the installation and construction process. Today, a few key points of the construction, installation, and purchase of the refrigeration unit water pipe are briefly explained. Everyone knows that many plastic products factories, mold cooling in the plastics industry, electroplating tank cooling in the electroplating industry, ultrasonic cleaning fluid cooling, various cooling in the chemical industry, various cooling in the food industry, and many other industries will be useful for refrigeration units, so how do you get the right pipes after you buy a refrigeration unit? I want to tell you some simple methods for selecting water pipes for refrigeration units. Hope to be of some help to my friends: 1. Pay attention to the heat preservation and moisture prevention of the water pipes. The heat preservation of the inlet and outlet pipes o

  In this article, the   air-cooled chiller manufacturer   will explain in detail the installation steps of industrial chillers and some simple daily maintenance tasks. I hope it will be helpful to everyone. Simply put, the installation process of industrial water chiller is roughly divided into the following 15 steps: 1. Please check whether the chiller is damaged before installation, and choose a suitable place to facilitate the chiller installation and future maintenance. 2. The installation site must be the floor, installation mat, or level foundation, the level of which is within 6.4mm and can bear the operating weight of the industrial water chiller. 3. The chiller should be placed in a computer room with a room temperature of 4.4 to 43.3 degrees. There should be enough space around and above the industrial water chiller for routine maintenance. 4. At one end of the industrial water chiller, there should be a space for cleaning the condenser tube bundle. You can also use door ope

  1. The temperature difference of the standard water chiller is 5 degrees (20 degrees drop 15 degrees) if a 10HP water chiller has a standard chiller flow rate of 5 cubic meters per hour. 2. When you try this chiller, you can't just look at the flow rate of the chiller, but also how much temperature you need. If the temperature you tried was dropped from 28 degrees to 7 degrees, if you try the chiller If the temperature difference is large, then the hourly chilled water flow will be reduced from 3.5 cubic meters to more than one cubic meter. Then if you need 5 cubic meters per hour, you have to choose a larger chiller. 3. When trying out the chiller, it depends on whether you are cooling directly or indirectly. Direct cooling is to feed water directly into the chiller, and the frozen water will directly cool the product you need, so the effect will be better, then Indirect cooling, for example, put water in a basin, put a small basin on top of the basin, and put the product to be

  Under normal circumstances, electroplating and anodizing   water chillers   can be divided into two types according to the cooling method: direct freezing and indirect freezing. Due to the corrosiveness of the electroplating (oxidation) industry, the concentration of some acids and alkalis is still very high. The water chiller is easy to corrode, so the direct refrigeration type adopts a titanium bubble water chiller or a 316L stainless steel water chiller. Therefore, the direct cooling water chiller is also called acid and alkali-resistant water chiller. The indirect refrigeration type does not require corrosion resistance treatment and can use a standard water chiller, but depending on the cooling method, the plating tank must be equipped with a titanium tube. 1. The principle and method of direct refrigeration The water in the bottom basin of the cooling tower is sent to the condenser of the water chiller through a water pump to cool the condenser and then flows back into the cool
