Detailed explanation of industrial screw type medium and low temperature chiller unit
The medium low temperature chiller is a new type of chiller designed and developed by our company based on years of experience in designing and producing piston type chillers, as well as the advantages of similar products at home and abroad. This product has the advantages of "high efficiency, energy saving, and environmental protection", and can be widely used in industries such as medicine, chemical industry, metallurgy, beverage and food, and artificial airports, providing a high-quality -35 ℃ to+5 ℃ level medium and low temperature freezing environment for its process. This product complies with the national standard GB/T18430.1-2001 "Steam Compression Cycle Cold Water (Heat Pump) Units for Industrial, Commercial, and Similar Use".
Principle of medium and low temperature screw chiller unit:
The screw type low-temperature chiller is used as a standalone unit, with a built-in fan as the heat dissipation device. The main air-cooled type cools the water at room temperature to a certain temperature through the chiller's compressor to enhance the cooling of the mold or machine. The electrical part is a Schneider product, with a water temperature control accuracy of ± 0.5 ℃ and a set temperature range of 5 ℃ -50 ℃. Special power supplies can be customized according to the power requirements of different countries and regions. If there is a lot of dirt on the finned condenser, simple dust can be blown clean with compressed air or a vacuum cleaner. The cooling capacity of high-quality and aesthetically pleasing products ranges from 8600Kcal/hr to several hundred thousand kcal (5HP-160HP), used in plastic machinery, rubber extrusion, plasma spraying, granulator molds, rollers, etc. The liquid refrigerant in the evaporator of the screw type low-temperature chiller absorbs heat from water and is then sucked in and compressed by the compressor (as pressure and temperature increase, a certain temperature difference is formed between the final refrigerant and water). Industrial cooling equipment using water as the refrigerant adopts vortex compressors and shell and tube condensers, which have the characteristics of high energy efficiency, low price, and large refrigeration capacity. They are widely used in industries such as chemical, electroplating, rubber and plastic, and food. The water tank used in the extrusion wire and granulation industry of the screw type low-temperature chiller is an open container, so when selecting the evaporator of the chiller, we should pay attention to the shell and tube type, and not the coil type. Large screen touch screen or text display, industrial grade intelligent controller computer are used. Control system.
