Screw industrial refrigeration unit

Screw industrial refrigeration unitThe classification of equipment models and the various names on the market may seem complex, so below are some commonly used refrigeration equipment:

1. Classified by condenser cooling method: air-cooled, water-cooled

2. Classified by compressor structure: screw type, piston type, vortex type, centrifugal type, etc

3. Classified by model structure: box type, open type, rack type, split type, etc

4. Classified by chilled water outlet temperature: standard air conditioning type (above 7 ℃), low-temperature cryogenic type (below 7 ℃), etc

5. Classified by cooling medium (refrigerant): saltwater, ethylene glycol, corrosion-resistant

Also, classified according to the principle of refrigerationCompression type, absorption type; Classified by evaporator structure type: full liquid type

Application industry of screw industrial refrigeration unit

1. Chemical industry

Mainly used for chemical reaction vesselsThe cooling of chemical heat exchangers timely removes the ordinary heat generated by chemical reactions to achieve the purpose of cooling and improve product quality.

2. Manufacturing industries of plastic products, plastic containers, food packaging films, medical packaging films, etc

Plastic productsIn the injection molding process of televisions, computers, washing machines, mobile phones, refrigerators, air conditioners, plastic toys, car plastic parts, etc., timely and effective cooling (cooling) will directly affect the brightness and qualification rate of the product's appearance, thereby affecting consumption efficiency, consumption costs, and enterprise profits.

Plastic ContainerThe consumption of blow molding and packaging film is even more dependent on the use of refrigeration units (ice water machines). If plastic containers are not cooled and shaped in a timely manner during the consumption process, the resulting containers will not be full, the wall thickness will be uneven, the color will not be bright, and even cannot be molded, resulting in lower product quality. Without the cooling and shaping of cold water (air) in the consumption of packaging film, qualified products cannot be produced. If the cold water (air) provided by the freezer (ice water machine) is used for cooling, it can not only greatly improve product quality, but also increase consumption efficiency.

3. Cooling of electroplating solution, hydraulic oil, and machine tool cutting tool coolant

In electroplating consumption, the electroplating solution continuously generates heat during the electroplating reaction, causing the temperature of the electroplating solution to gradually decrease. When the temperature of the electroplating solution exceeds the requirements of the process, it has a significant impact on the stability, uniformity, flatness, and brightness of the surface coating of the electroplated product consumed. And choose to use a freezerThe consumption process of frozen electronic components provided by the ice water machine requires the components to be maintained or cooled at a specific temperature in order to control the performance parameters of the electronic components in the designed state. Using water to cool and maintain the constant temperature of the electroplating solution will greatly improve the consumption process and efficiency of electroplating.

The cooling of machine tool cutting tool coolant and the control of tool edge temperature will directly affect the application life and product quantity of the tool.

4. Pharmaceutical industry

The pharmaceutical industry is mainly used for controlling the temperature and humidity in the consumption workshop, as well as for removing the reaction heat during the consumption of raw materials

5. Electronic industry

During the consumption process of electronic components, it is necessary to maintain or cool the components at a specific temperature in order to control the performance parameters of the electronic components in the designed state

6. It is widely used in various fields such as papermaking, textiles, brewing, pharmaceuticals, food, machinery, beverages, vacuum coating, electroplating, central air conditioning, etc. It is also commonly used in centralized cooling methods to facilitate centralized pipes
