Application scenarios of water-cooled screw chiller
- If you are engaged in injection molding, laser processing, or chemical production, the equipment generates a lot of heat. Our water-cooled screw compressor is specifically designed to solve this problem. When equipped with it for injection molding machines, it can stably control the mold temperature within ±0.5℃, preventing product shrinkage and deformation. The laser is cooled by it, ensuring that the beam quality does not drift and the cutting accuracy is maintained.
- The cooling of the reaction vessel is even more crucial. This machine maintains the set value 24 hours a day, so your workshop doesn’t need to get up in the middle of the night to adjust the parameters. The unified layout of the circulating water system ensures stable heat dissipation of the equipment and reduces the failure rate by half.
When you manage a shopping mall or a complex, the large space is crowded with people, making heat dissipation difficult. You also need to take into account constant temperature and humidity. Water-cooled screw compressors take up less space than air-cooled ones and do not occupy business area. It has a high energy efficiency ratio, consumes less electricity for the same cooling capacity, and saves on electricity bills over long-term use. During the peak tourist season in summer, it can quickly cool down the temperature, so customers won’t feel bored while strolling. In winter, when combined with heat recovery, it can also provide heating.

What Is A Water Cooled Screw Chiller
Water-cooled screw chiller adopts advanced technology, with a screw compressor as the core, to turn ordinary water into chilled water. This chilled water can be sent to the air conditioners in shopping malls, industrial equipment, etc., to help cool down these devices.
Water-cooled screw type chiller.
The Crucial Structure of A Water-Cooled Screw Chiller
Screw Compressor
The Importance of Compressors
The screw compressor is the power source of the water-cooled screw water cooled chiller and directly determines the overall energy efficiency and stability of the machine. The job of a compressor is to compress the refrigerant into a high-temperature and high-pressure state.
The Advantages of Duopu Water-Cooled Compressors
The screw compressor we use has a double-rotor structure, and the clearance is controlled to be extremely small. The surface has undergone special coating treatment, which is wear-resistant and high-pressure resistant, and is not prone to problems even after long-term high-load operation.
Heat Exchange System
Condenser
The heat in your workshop is eventually dissipated by it. We use high-efficiency shell and tube condensers. Compared with air cooling, water cooling has a lower condensing pressure, a lighter compressor load, and less power consumption. If there are ready-made cooling towers or circulating water pools in your factory, they can be used immediately after being connected. No additional fans are needed, and the noise in the workshop is also low.
Evaporator
This is the direct part of cooling down your equipment. By using an evaporator, the refrigerant evaporates and absorbs heat. The heat from your reaction vessel, injection molding machine, and other heat sources is carried away by the chilled water outside the tubes.
Throttling Device
The throttling device is a crucial step located between the condenser and the evaporator, specifically designed to reduce the pressure and temperature of the refrigerant. The refrigerant passes through here, and its pressure drops sharply, turning into a low-temperature and low-pressure gas-liquid mixture, which can then rush into the evaporator to absorb the heat of your equipment.
Chilled Water System
The chilled water system is responsible for steadily delivering the coldness. This cycle directly determines the speed and effect of cooling. We chose a low-noise centrifugal pump. The head is stable enough. It doesn’t matter if the cooling circuit of your equipment is longer. The water flow pressure fluctuates little.
The Working Principle of A Water-Cooled Screw Chiller
Compression
The screw compressor is the starting point. The low-temperature and low-pressure refrigerant gas is drawn in, squeezing these gases into a high-temperature and high-pressure state. This step is like inflating the refrigerant, allowing it to carry sufficient heat to the condenser. The compressors we use have small clearances, wear-resistant coatings, and high compression efficiency. Your equipment that generates a lot of heat, such as reaction vessels and injection molding machines, cools down more quickly.
Condensation
The compressed refrigerant gas enters the condenser. Meanwhile, chilled water flows outside the pipes, and the refrigerant releases heat and turns into a liquid.
Expansion
The liquefied refrigerant flows to the expansion valve. Suddenly reduce the pressure of the high-pressure liquid and turn it into a low-temperature and low-pressure mist-like liquid. We adjusted the expansion valve accurately, the pressure dropped steadily, and the refrigerant state was just right for the next step of heat absorption.
Evaporation
The refrigerant enters the evaporator. The refrigerant absorbs the heat from the equipment, turns back into a low-temperature and low-pressure gas, and is then sucked away by the compressor, completing one cycle.
Features of The Water-Cooled Screw Chiller
Stable Heat Exchange Efficiency
With a falling film design, the refrigerant is directly dripped onto the inner wall of the heat exchange tube and exchanges heat with the opposite side of the chilled water surface. It cools down quickly and evenly.
Dual system guarantee
Equipped with backup operation and oil recovery. When the main system temporarily stops working, the backup machine immediately takes over, and the production line does not stop. The oil recovery system automatically collects waste oil, eliminating the need for frequent oil changes and making maintenance convenient.
intelligent control
It is smaller in size and can fit in your crowded workshop. The adoption of a new type of chiller controller makes installation and control more convenient.
Heat pump + ice storage for cooling
Combining heat pump waste heat collection and ice storage technologies. It uses cold for production during the day and stores cold at night to save electricity. During peak season, the cooling demand is high. Heat pumps are used for supplementary cooling, eliminating the need for additional units and adapting to your fluctuating production capacity.
Falling film evaporator vs immersion evaporator
Falling film evaporator
- Its shell side is filled with liquid refrigerant, and the heat exchange tubes are directly immersed in it. The refrigerant boils and bubbles outside the tube. Heat is transferred by the bursting of the bubbles, and the chilled water inside the tube is cooled.
- The bubbles are unevenly distributed. Some parts of the pipe have fast heat exchange, while others have slow heat exchange. The cooling of your production line equipment is prone to sudden changes in temperature. Moreover, it requires a large amount of refrigerant to be filled, which not only takes up space but also increases costs. In case of leakage, it is also troublesome to repair it.
immersion evaporator
- Our water-cooled screw chiller adopts the falling film evaporator technology. It uses the top distributor to evenly drip the refrigerant onto the inner walls of the stacked heat exchange tubes. The chilled water flows outside the pipe, while the refrigerant flows down along the pipe wall.
- This method is more efficient. The refrigerant follows the pipe wall, and each pipe can fully absorb heat. The cooling of your reaction vessels, injection molding machines, and other equipment is more uniform. It uses less refrigerant, saving labor for charging and leak repair. With a high heat transfer coefficient, the same power can carry away more heat, and you can save on your electricity bill.
Our unit is equipped with an automatic emergency backup system as standard. When a certain compressor malfunctions, the standby one immediately takes over. In this way, your key equipment, such as reaction vessels and injection molding machines, will not get cold, and production will not be interrupted. The backup is in standby mode during normal times. It starts up immediately in case of a fault, ensuring your continuous production is not affected.
If you choose a water-cooled screw chiller, the installation is quite worry-free. Our compressor adopts a lightweight design and is much lighter than the traditional model. You won’t have any trouble moving or positioning it. The unit frame is pre-assembled and can be fixed on site by tightening a few screws. The pipe interfaces are of standardized specifications and can be directly connected to your existing cooling water system without the need to modify the pipes. There are also video guides. If you have any problems, contact the after-sales service. It can be turned on and used in as fast as one day.
We are equipped with a 15-inch touch screen, making operation effortless. The historical records store the data of each operation. Changes in temperature and pressure can be easily checked, and equipment abnormalities are easy to trace. The information page displays the working conditions of the water pump and compressor in real time. The planned tasks can be set to turn on and off at specific times, which can be coordinated with the production schedule to save energy consumption. Reports are automatically generated, and energy consumption and fault data can be exported conveniently.
We have equipped the unit with a heat pump module, which can recover the waste heat discharged during the cooling of industrial equipment. This heat recovery system is highly adaptable. If there is a lot of waste heat in your production line, it will provide a stable heat supply. One machine can handle both cold and hot water, making it more cost-effective to use.
Whether to use a water-cooled or air-cooled screw chiller depends on where you are going to use it. If there is a circulating cooling water system, choose water cooling. It has a high heat exchange efficiency and saves electricity. If there is no reserved space for the cooling tower in the factory building or the heat generated by the equipment is small, air cooling should be selected. No need to connect water pipes, quick installation. The key is to match the requirements. For constant temperature and large-scale heat dissipation, water cooling is more reliable. If you want to save trouble and have a tight budget, air cooling is also sufficient.
