Introduction to the Classification of Chillers

Chiller is a kind of refrigeration equipment commonly used in industrial production. It is widely used in chemical medicine, plastic mold and other industries. There are many types of chiller applications, such as air-cooled chillers and water-cooled chillers that are often heard. There are many kinds of chillers, low temperature chillers, screw chillers, etc. Many users often can’t tell them apart. They don’t know how to classify chillers? The following LNEYA professional chiller manufacturers can introduce them to you.

1. According to the packaging form, there are two types: open type (without outer box) and sealed type (box type) chiller.

Open type: It is generally installed outside the workshop for easy maintenance and lack of aesthetics.

Sealed type: box structure, easy to install, easy to use, beautiful in appearance, more popular in the current customer base.

2. According to the condensation method: There are mainly two types of water-cooled chillers そして air-cooled chillers.

Water-cooled type: The chiller is connected to external cooling water to take away the heat of the refrigerant in the condenser.

Air-cooled type: The chiller is equipped with a cooling fan to take away the heat of the refrigerant in the condenser.

3. According to the type of evaporator, there are two types: submerged type and shell tank type.

Submerged type: The evaporator is immersed in the water tank to achieve refrigeration, and the water pump pumps water from the water tank to achieve circulation. (Feature: Refrigerate first, then pump water)

Shell tank type: The evaporator is made into a long cylindrical tank, and the water pump is pumped from the water tank and injected into the evaporator to achieve refrigeration. (Feature: Pumping water first, cooling later)

4. According to the type of compressor, there are three types: piston chiller, screw chiller and centrifugal chiller.

Piston refrigeration: using piston refrigeration compressor, it has the advantages of multi-cylinder, high speed, adjustable energy, high thermal efficiency, suitable for various refrigerants, etc., but the structure is more complex, there are many wearing parts, the maintenance cycle is short, and there is pulse vibration. and poor running stability.

Screw type: It uses the screw type refrigeration compressor imported from the original brand, with simple structure, few wearing parts, small volume, light weight, large single-machine compression ratio, high refrigeration capacity, maintenance cycle factory, stable operation and long service life.

Centrifugal type: using a centrifugal compressor and using electricity as a power source, the freon refrigerant evaporates in the evaporator and absorbs the heat of the refrigerant water for cooling.

5. According to the temperature, it can be divided into ordinary chiller (5~50℃), low temperature chiller (-60~-20℃) and ultra-low temperature chiller (-120℃).

Different industries have different requirements for the use of chillers, and various types of chillers can meet the purchase needs of various industries.
