Water Cooled Screw Chiller

GESON Centrifugal Chiller

Screw chiller has water cooled chillers and air cooled chiller.

Water cooled chiller need to work with cooling towers.

Screw Type Chiller Advantages:

1. Simple structure, fewer moving parts, less wearing parts, only 1/10 of the piston type, low failure rate, and long life screw compressor.
2. Screw compressors screw chiller has a smooth circular motion, no “surge” phenomenon during the low load operation, low noise, and low vibration.

Screw Compressor

1. The screw compressors’ compression ratio can be as high as 20, and the EER value is high.
2. Convenient adjustment, step-less adjustment within the range of 10% to 100%, high efficiency at part load, and significant power saving.
3. Small size and lightweight, can be built into a fully enclosed large capacity unit, because of screw compressor.
4. Chiller Screw type with screw compressors are not sensitive to wet stroke.
5. It belongs to positive pressure operation, and there is no problem of external air intrusion and corrosion.

Disadvantages:

1. The price is higher than the piston type.
2. The capacity of the single machine is smaller than that of the centrifugal type, and the rotation speed is lower variable speed.
3. The lubricating oil system is more complicated and consumes more oil.
4. The large-capacity unit has higher noise.
5. High machining accuracy and assembly accuracy are required

Advantage:

The impeller has a high rotation speed, large gas transmission volume, and large single machine capacity.

Fewer wearing parts, reliable work, compact structure, stable operation, small vibration, and low noise.

The weighted index per unit cooling capacity is small.

No lubricant is mixed in condenser the refrigerant, and the removes heat entering the evaporator and the condenser is good.

The EER value is high and the theoretical value can be reached. 6.996. Easy adjustment, stepless adjustment within 10% ~ 100%.

Disadvantages of centrifugal chillers:

The single-stage compressor will appear “surge” phenomenon at low load and run smoothly at full load.

Centrifugal chillers Strict requirements on material strength, processing accuracy, and manufacturing quality.

When the operating conditions deviate from the design conditions, the efficiency decreases faster, and the cooling capacity decreases faster than the piston type as the evaporation temperature decreases.

Centrifugal negative pressure system, outside air, is easy to invade, there is a risk of chemical changes corroding pipelines.

What is Centrifugal Chiller?

A centrifugal chiller is a device that is used in order to cool water. The design of the centrifugal chiller is such that it has a rotating impeller that forces water through a tube and then out into the atmosphere. The rotation of the impeller creates an area of low pressure on the inside of the tube, which causes cold water to be drawn in from outside and pumped through the tube.

The centrifugal chiller can be used in many different industries, including food processing plants, breweries, and chemical plants. There are two types of centrifugal chillers: internal and external. External chillers are usually placed outside so as to allow for easier access by workers or for easier connection to other devices like pipes or pumps. Internal chillers are usually smaller and more compact than

What is the difference between chiller screw type and centrifugal chiller?

Screw type chiller and centrifugal chiller are two types of chilling equipment. Chiller screw type is a more traditional type of equipment. It works by cooling the water that goes into it, which in turn cools the food and beverages.

Centrifugal chiller on the other hand, is a newer type of technology. It works by spinning a cylinder filled with ice around to cool the water in it and then pumps that cold water onto the food or beverages that need to be cooled.

The only difference between these two types of chillers is how they work. They both have their pros and cons but typically screw chillers are used for smaller production volumes while centrifugal chillers are used for larger production volumes.

Which type of chiller is best?

A screw type chiller is a type of chiller that uses a coiled tube to cool water. The coil is usually made of copper, but it can be made out of other metals, such as aluminum. A screw type chiller is best for cooling small amounts of water to a moderate temperature.

A centrifugal chiller is a type of chiller that uses centrifugal force to cool water. The water enters the machine through the inlet and then exits through the outlet pipe. A centrifugal chiller is best for cooling large amounts of water to a high temperature.
