Industrial chiller (industrial chiller) is a device from the family of condensation chillers whose operation is based on the condensation refrigeration cycle. Industrial chiller is used in various industries with the aim of absorbing excess heat in machines and production processes in order to cool and reduce temperature. Industrial chiller is used in cooling plastic injection machines, food industry, etc.
Due to the special role of heat transfer (cooling) in the correct operation of these machines and the production of quality products, the manufacture of industrial chillers requires the observance of important points that naturally affect the purchase price of these chillers. For this reason, the main use of industrial chillers is in industrial refrigeration or process cooling. Cold water produced by industrial chillers is widely used in the following industries: Industry Polymer, especially cooling and cooling of plastic injection molds
food industry
health industry and pharmaceutical companies
petrochemical and oil and gas industry
tile and ceramic industry
printing industry
industry Cement
Application of Industrial Chiller Machine
The use of cold water produced by chillers in buildings as a water air conditioning system is one of the solutions that has become one of the most common and important cooling equipment along with terminal units called fan coils or air conditioners. is However, another widespread application of chiller is its use in various industries. There are many production lines in industries that require cooling in a part of their process to achieve the desired product, which is called Process cooling. In other words, Process cooling is a type of cooling mechanism that is used to remove heat from a production process.
Plastic industry, injection and casting, metalworking, welding, machine tools, petrochemical, pharmaceutical, healthcare , food production and storage, fish breeding, paper and cement, road construction, etc. are among the industries that use industrial chiller devices for cooling and producing cold. did.
Evapctor frost in industrial chillers
Many industrial chillers are not on all day and night. Therefore, in areas that have very cold nights in the winter season, if the chiller is not turned on and the water does not circulate in it, there will be a risk of the evaporator freezing. There are ways to prevent this from happening. including:
1- Use of antifreeze: One of the simplest methods available to prevent freezing of the evaporator in winter nights is to add antifreeze (glycol) to The water flow is circulating. So that the lower the minimum temperature in the project site, the more percentage of antifreeze should be added to the water. It is on day and night and never allows the water to fall out of circulation, there is no more risk of water freezing in the evaporator. Of course, this method will be a bit risky; Because the pump may have a problem and stop working for any reason. As a result, it is better to use a reserve pump in parallel with the main pump, especially in industrial chillers. It is installed on the shell. This mechanism will not allow the surface temperature of the evaporator shell to fall below a certain limit. Of course, these thermal elements should be used in that part of the chiller's return pipes that are in the vicinity of the open air.
Industrial chiller to produce and maintain food
The food industry is a complex and global network of diverse businesses that provide most of the food consumed by people around the world. The term food industry includes a set of industrial activities including production, distribution, processing, transformation, preparation, storage, transportation, certification and packaging of food.
Industrial chiller in the pharmaceutical industry
The pharmaceutical industry, in fact, is the discovery and production of raw materials (with medicinal properties), their transformation into medicine and the supply of the obtained product in the market for the use of patients. The production of these medicinal substances, which is actually considered one of the chemical industries, includes processes that sometimes require cold water. Cold water, which is usually provided by a chiller.
Almost all pharmaceutical manufacturers use industrial refrigeration equipment as part of their production processes. This equipment provides cooling water for important applications such as research and development, batch processing, cream and ointment cooling, liquid sterilization, tableting, packaging and more.
