Chillers are generally used in air-conditioning units and industrial cooling. Generally speaking, water chiller can be divided into water-cooled and air-cooled according to the form of refrigeration. Technically, water-cooled energy efficiency is much higher than air-cooled. In terms of price, water-cooled is lower than air-cooled. It is more troublesome. Water cooling requires a cooling tower before it can be used. Air cooling is removable. Installation is simpler and does not require other auxiliary equipment. However, air-cooled chiller only uses fans to dissipate heat, which has certain requirements on the environment. Today the  Water Cooled Screw Chiller Factory  introduces the features of the water-cooled chiller. Water-cooled chiller features: Feature one 1. Small size, large cooling capacity, imported compressors from world famous brands, excellent low temperature performance, reliable and durable. 2. Low noise fan motor, excellent cooling and condensing ...

With the development of the industrial economy, the use of chillers is becoming more and more widespread, and more and more people and industries are exposed to chillers. When we buy chiller, we often hear the term screw chiller. Its screw chiller is a type of chiller, which is commonly known as  Air Cooled Screw Chiller  because of its use of screw compressors. Because its cooling power is greater than the power of the scroll chiller, so some chemical plants, automobile manufacturers, ink printing plants will choose screw chiller for use. Air Cooled Screw Chiller So do you know what are the characteristics of screw chiller? The  Water Cooled Screw Chiller Factory  will tell you below. Features of screw chiller: 1. The evaporator and condenser of the screw chiller have been integrated into a whole, which no longer takes up additional space. In addition, the unit is simple and does not require a large maintenance space, so the area of the machine ro...

Because the leakage of the chiller system not only causes the refrigerant to leak or the outside air to penetrate, affecting the normal operation of the refrigeration device, but also causing economic losses and polluting the environment. Therefore, the tightness of the chiller system is usually an important indicator of the quality of the installation or manufacturing of the refrigeration device. However, due to the large number of welding points and joints in the installation or assembly process of large-scale chiller systems, leakage is inevitable. This requires commissioning personnel to carefully check the system for leaks, and find and eliminate each leak. Leak detection of the system is the main project in the entire debugging work, and it must be carried out carefully, meticulously and patiently. The  Water Chilling Machine Manufacturer  will share the methods below. 1. Pressure leak detection Leak detection of chiller refrigeration system pressure is the most e...

Today, the  Water Chilling Machine Manufacturer  will introduce how to deal with the difference between the temperature of the water entering the chiller and the temperature of the water coming out of the chiller. 1. The output cold capacity of the chiller is small, such as the unit itself is faulty, or is not fully loaded, etc. These can be preliminary judged by observing the operating current of the chiller unit and other parameters. 2. It may also be that the heat transfer effect is not good. For example, the scaling of the heat transfer tube is serious and the heat exchange of the chiller is affected. This can be judged by observing the heat transfer temperature difference between the water temperature and the evaporation temperature. 3. The water flow is too large. This can be judged by observing the pressure difference between the inlet and outlet water of the evaporator and the running current of the pump. 4. After eliminating the above problems, you can cons...

As we all know, when using air-cooled chiller, it is necessary to pay attention to the control of noise, and to comprehensively deal with the noise in an effective time, to avoid various noise problems affecting the normal operation of the equipment. Although the air-cooled chiller will cause slight noise problems in the daily use process, it is within the acceptable range. If the noise range of the air-cooled chiller continues to expand, it means that the air-cooled chiller has a fault and needs to be comprehensively tested. The  Air Cooled Chiller Exporter  will introduce the location of noise generated by air-cooled chiller. Compressors, circulating water pumps and cooling fans are the main noise sources of air-cooled chiller. Since the operation of this type of equipment generates noise, the change in the size of the noise mainly depends on the above types of equipment. In the case of increasing noise, companies need to conduct comprehensive inspections of various...

Due to the high stability of the air-cooled  Industrial Water Chiller , the industrial chiller can be applied to different operating environments. Therefore, when an enterprise chooses an industrial chiller, it takes the air-cooled industrial chiller as its main product type. In terms of stability and high power, enterprises often take the stability of long-term operation of industrial chiller as the main selection criterion. 1. Stable operation of air-cooled industrial chiller Due to the use of air-cooled cooling, the industrial chiller is not limited by any environment. As long as there is an air circulation location, enterprises can complete the installation of industrial chiller equipment. Of course, in an environment with a high ventilation coefficient, the air-cooled industrial chiller runs more efficiently, and the time it takes to create a low-temperature environment for the enterprise is very short. Many domestic large enterprises cannot provide high-quality wat...

The operating conditions of the  Industrial Water Chiller  refrigeration system are good or bad, which has a great impact on the chiller. The purpose of adjusting the main parameters of a refrigeration system is to adjust each parameter so that it operates under the most reasonable conditions. Especially for those screw chiller units with larger power, the debugging work is not done well, which will directly affect the later refrigeration effect. (1) Charge of refrigerant. At present, refrigeration units are generally charged with refrigerant in accordance with regulations before leaving the factory. After installation on site, if no accidental damage is found in the visual inspection, the relevant valve can be opened directly for commissioning. (2) Some screw chiller units, such as  Water Cooled Screw Chiller , need to be filled with refrigerant at the user's site. The refrigerant charge and refrigerant brand must be in accordance with regulations. Insufficient ...
