There are kinds of chillers, such as  Air Cooled Scroll Chiller,  auto water cooled Chiller and others. But whatever the chiller is, there are some factors affecting the cooling capacity of chillers. Air Cooled Scroll Chiller A chiller is an energy-saving machine that achieves refrigeration by steam compression or absorption cycles. What are the factors that affect the cooling capacity of the chiller? Let us introduce it to you. Factors affecting the cooling capacity of the chiller: 1. Compressor power: The higher the power, the higher the cooling capacity. According to the size of the model, the compressors of different types are selected. For example, the small chiller is piston type, the medium type is equipped with scroll type, and the large type is screw type. , centrifugal and so on. 2. Water temperature (evaporation temperature is different, cooling capacity is different): The higher the water temperature, the larger the cooling capacity, and the lower the water

The chiller is a water cooling device that can provide constant temperature, constant current and constant pressure cooling water equipment.  China Water Chilling System  has its own working principle, that is first inject a certain amount of water into the water tank of the machine, cool the water through the refrigeration system, and then cool the water by the water pump. The cooling water is sent to the equipment to be cooled, and the chilled water takes the heat away, and then the temperature rises and then flows back to the water tank to achieve the cooling effect. However, in the long-term use of chillers, there are often some dirt deposits in the chiller pipe or water tank. How do these deposits come from? China Water Chilling System 1. Chemical processor If a zinc salt or a phosphate inhibitor is added to the water circulation system, zinc or phosphate scale is formed. Therefore, we must always carry out maintenance work on the chiller, not only to ensure its cooli

According to different cooling methods, industrial chillers are divided into  Water Cooled Chiller Machine  and  Air Cooled Chiller . The difference between them is mainly due to the difference in condensers. Water Cooled Chiller Machine The condenser of the water cooled chiller mainly removes heat by circulating cooling water. Therefore, the condenser of the water cooled chiller is usually shell-and-tube type, commonly known as blisters. Unlike the water cooled type, the air cooled chiller uses a finned condenser. The fins are actually aluminum sheets. The parts that require heat exchange are externally mounted with aluminum sheets to achieve efficient heat dissipation. Hot air is pumped out. Air Cooled Chiller Therefore, depending on the way the two chillers dissipate heat, the places where they are installed are also learned. Water cooled chillers can be installed outdoors or indoors; on the contrary, air cooled chillers can only be installed outdoors. This is b

Water Cooled Chiller Machine  is one of the models of industrial chillers. Due to different industries, there are countless names. Water-cooled chillers are also known as: chillers, freezers, chillers, refrigeration units, cooling water cycle machines. and many more. Water Cooled Chiller Machine The working principle of the water cooled chiller machine is that it uses the (shell-tube/water tank coil type) evaporator to exchange heat between the water and the refrigerant. The refrigerant system absorbs the heat load in the water, so that the water cools down to produce cold water, and then passes through the function of the compressor. The heat is brought to the shell and tube condenser, and the heat exchange between the refrigerant and the water is performed, so that the water absorbs the heat and then the heat is taken out of the external cooling tower through the water pipe.
