What Is a Screw Chiller?

The difference between the screw chiller and the ordinary chiller is that the screw chiller uses a screw compressor, while the ordinary chiller uses a scroll compressor, the screw chiller is relatively larger than the ordinary chiller, the use scenario and the effect are not the same, the cooling capacity of the screw chiller is larger, which is more suitable for refrigeration in large industries and large places.

1. What is a screw chiller

A screw chiller is a steam compressor type chiller that uses a screw compressor to transport the coolant into the system. Some of the main advantages include compact installation, quiet operation, lower maintenance costs and high energy efficiency, while they are also ideal for tall buildings.

Components: It is mainly composed of semi-hermetic screw compressor, shell and tube condenser, filter dryer, thermal expansion valve, shell and tube evaporator, and electrical control part.

Working principle: Like the ordinary chiller, the cooling principle of the screw chiller is also the water cycle, usually by the pump from the water tank to the user needs to cool the equipment, the chilled water will take the heat away after the temperature rises, and then back to the chilled water tank.

Screw chiller also has two options of air-cooled and water-cooled, customers can choose their own chiller according to their needs.

2. Characteristics of screw chiller

1. The unit adopts semi-hermetic screw compressor, graded or step less energy regulation, automatic adjustment according to load changes, more energy saving.

2. All refrigeration units of our company are equipped with 6 protection, so that the unit runs safely and reliably. The unit adopts direct cooling mode, which reduces the loss of intermediate heat exchanger and greatly reduces the operating cost.

3. In addition to R22 R134a, there are a variety of refrigerants to choose from

4. Our screw chiller uses an efficient heat exchanger, which improves the cooling efficiency and saves the operating cost of the machine.

5. Intelligent computer control system, can do 485 communication, one-click operation, simple and fast.

6. How to choose the right screw chiller

Their own needs: different number of pieces and different kinds of refrigeration effects and refrigeration methods are different, different power screw chiller use scenarios are not the same, customers according to their own production requirements to choose the right screw machine to ensure the refrigeration effect.

If the requirements are vague, you can consult our company, we will provide you with free customized solutions to meet customer refrigeration needs.

Machine type: The cooling effect of air-cooled and water-cooled screw mechanism is the same, but the heat dissipation method is different, air-cooled type is heat dissipation by fan, water-cooled type is heat dissipation by cooling tower, and the type of machine purchased can be determined according to the local environment and the machine use environment.

If water resources are scarce in the region, air-cooled cooling can be a good way to meet the cooling needs. If there is no water shortage in the area and there is a cooling tower in the location, then you can buy a water-cooled machine.

The above is the detailed information about the screw chiller, the cooling capacity of the screw chiller is large, the cooling effect is good, it is the only choice for large refrigeration projects, if you are interested, you can contact us, we will reply to you in the first time.
