Using glycol in chillers offers several advantages, including:
Lower Freezing Point: Glycol mixtures have a much lower freezing point than water, which prevents the coolant from freezing in the chiller system, especially in low-temperature applications. This property makes glycol ideal for environments where temperatures can drop below the freezing point of water.

Improved Heat Transfer Efficiency: Glycol enhances the heat transfer properties of the coolant, which can improve the overall efficiency of the chiller system. This results in better cooling performance and energy savings.

Corrosion Inhibition: Glycol-based coolants often contain corrosion inhibitors that protect the metal components of the chiller system from rust and corrosion. This extends the lifespan of the equipment and reduces maintenance costs.

Enhanced Fluid Stability: Glycol solutions are chemically stable and less likely to degrade over time compared to other coolants. This stability ensures consistent performance and reduces the need for frequent fluid replacement.

Wide Temperature Range: Glycol chillers can operate effectively across a wide range of temperatures, making them suitable for various industrial applications, from low-temperature cooling to high-temperature heat rejection.

Reduced Risk of Biological Growth: Glycol inhibits the growth of bacteria and algae, which can be a problem in water-only systems. This reduces the need for biocides and other chemical treatments, lowering maintenance costs and complexity.

Non-Flammability: Most glycol solutions are non-flammable, making them safer to use in environments where flammable coolants might pose a risk.

Compatibility with Various Systems: Glycol is compatible with a wide range of materials commonly used in chiller systems, including metals and plastics, reducing the risk of material degradation or failure.

Lower Viscosity at Low Temperatures: Glycol solutions maintain lower viscosity at low temperatures compared to pure water, which helps in maintaining fluid flow and reducing the load on pumps and other components.

Environmental and Safety Considerations: Propylene glycol, in particular, is less toxic and more environmentally friendly compared to ethylene glycol. This makes it a preferred choice in applications where there is a risk of coolant leakage into the environment or contact with food and beverages.

Screw chiller and centrifugal chiller are equipment that we often encounter. Below, Oumal Refrigeration will take you to understand the difference between centrifugal chiller and screw chiller?

What is a screw chiller?

The compressor adopts a screw type, hence the name screw chiller. The refrigerant coming out of the evaporator of the unit is a gas; after adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state.

The compressed gas refrigerant is isobarically cooled and condensed in the condenser. After condensation, it changes into liquid refrigerant, and then expands to low pressure through the throttle valve and becomes a gas-liquid mixture.

The liquid refrigerant under low temperature and low pressure absorbs the heat of the cooled material in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. These are the four processes of the freezing cycle. It is also the main working principle of screw chiller.

2. What is a centrifugal chiller?

The biggest difference from the screw chiller is that it uses a centrifugal compressor.

It is a cooling system that uses the principle of centrifugal force to remove heat from the inside of the fluid. It is composed of centrifugal refrigeration compressor, evaporator, condenser, main motor, air extraction recovery device, lubrication system, control cabinet and starting cabinet. Some of these components are assembled in a decentralized manner, but most are "assembled" units in which each component is put together. The units are divided into fully enclosed, semi-enclosed and open types.

Both centrifugal and screw chillers are types of refrigeration systems commonly used for cooling in various applications. While they serve a similar purpose, there are some key differences between the two different chillers:

Working Principle:

Centrifugal Chiller: Centrifugal chillers use a rotating impeller and centrifugal force to compress and cool the refrigerant.

Screw Chiller: Screw chillers use two rotating screws (male and female) to compress and cool the refrigerant.

Capacity:

Centrifugal Chiller: Centrifugal chillers are typically available in larger capacities, ranging from several hundred tons to several thousand tons of refrigeration.

Screw Chiller: Screw chillers are available in a wide range of capacities, but they are generally suitable for smaller to medium-sized applications.

Energy Efficiency:

Centrifugal Chiller: Centrifugal chillers are known for their high energy efficiency, especially at full load conditions. They are designed to provide efficient cooling for large-scale applications.

Screw Chiller: Screw chillers also offer good energy efficiency, but their efficiency may vary based on operating conditions and load levels.

Operating Characteristics:

Centrifugal Chiller: Centrifugal chillers are often used in applications with varying loads and where precise temperature control is required. They can handle load variations effectively and provide good part-load performance.

Screw Chiller: Screw chillers are suitable for applications with relatively constant loads, as they are generally more efficient at full load conditions. They are commonly used in commercial and industrial settings.

Maintenance and Service:

Centrifugal Chiller: Centrifugal chillers typically require specialized maintenance and service due to their complex design and construction.

Screw Chiller: Screw chillers are relatively easier to maintain and service compared to centrifugal chillers, primarily due to their simpler design and fewer moving parts.

It's important to note that the selection between centrifugal and screw chillers depends on various factors such as cooling requirements, capacity, energy efficiency goals, load characteristics, and budget considerations. Consulting with a professional HVAC engineer or chiller manufacturer can help determine the most suitable chiller type for specific applications.

Ensuring the longevity of an industrial air cooled chiller involves a series of diligent maintenance practices designed to maintain optimal performance and prevent premature wear. Regular inspections and upkeep are critical for the efficient operation of these systems. For an air cooled screw chiller, frequent checks of key components such as the compressor, condenser coils, and evaporator are essential. The compressor should be monitored for any signs of wear or inefficiency, like unusual noises or vibrations, which could indicate potential issues. Keeping the condenser coils clean is equally important, as dirt and debris can obstruct airflow and reduce the system’s efficiency.

Maintaining proper refrigerant levels is another crucial aspect of prolonging the life of an industrial air cooled chiller. Low refrigerant levels can cause the system to overheat, potentially damaging the compressor and other components. Regular monitoring and replenishment of refrigerant help maintain the system’s efficiency and prevent breakdowns. Additionally, inspecting and replacing worn-out seals and gaskets can prevent leaks and ensure the system operates smoothly. This practice is particularly important in maintaining the effectiveness of the water chiller cooling system, which relies on precise refrigerant levels for optimal performance.

Lubrication of moving parts is vital for the longevity of an air cooled screw chiller. Regularly checking and replacing lubricants as specified by the manufacturer reduces friction and wear, thereby extending the life of components such as the compressor and fans. Ensuring all moving parts are well-lubricated prevents overheating and excessive wear, which can lead to costly repairs and downtime. Regular maintenance should also include checking the electrical connections and control systems to ensure they are functioning correctly, as faulty electrical connections can lead to system malfunctions or even complete failures.

Maintaining optimal airflow around the chiller unit is crucial. Ensuring there are no obstructions around the air intake and exhaust areas helps maintain proper airflow, essential for efficient cooling. Regularly inspecting and cleaning the air filters also ensures that the system operates at peak efficiency. This practice is particularly important for an industrial air cooled chiller, where maintaining consistent airflow directly impacts the cooling performance and energy efficiency of the system.

Water quality is another important factor in maintaining the water chiller cooling system. Regularly checking and treating the water to prevent scale build-up and corrosion can prolong the life of the chiller. Ensuring that the water treatment systems are functioning properly and that the water is free of contaminants helps to prevent damage to internal components. This maintenance practice is essential for avoiding costly repairs and ensuring the efficient operation of the chiller system.

Implementing a proactive maintenance schedule is key to ensuring the longevity of an industrial air cooled chiller. Keeping detailed records of all maintenance activities and scheduling regular service checks by qualified technicians helps identify potential issues early and address them before they escalate into major problems. By adhering to these maintenance practices, operators can significantly enhance the longevity and performance of their chillers, minimizing downtime and maximizing the return on their investment.

Like all chiller systems, a water cooled screw chiller consists of an evaporator, expansion valve, refrigerant, internal piping and controls. The main difference between screw chillers is their compressor. Screw chillers use two helical rotors to drive and compress the refrigerant gas. This type of chiller has nearly constant flow performance and is powered by an electric motor, steam or gas turbine. They are available in capacities ranging from 25 to 800 tons and are very effective when used with liquids with high evaporative temperatures.

Screw or helical compressors in screw chillers consist of two matched helical groove rotors: convex baffle and groove. They are mounted in a fixed housing and move simultaneously. As they rotate, the refrigerant gas is compressed and converted to vapor by the direct volume reduction between the two rotors.

These compressors are equipped with sliders that adjust the length of the compression path. Intake, compression and discharge take place in a linear direction. An oil lubricant on the rotor also acts as a sealant. The motor is cooled as the refrigerant flows through the holes in the screw, which acts as a liquid separator. It is important that the screw chillers are properly sized.

When they are too large, they have a long reverse cycle time and will shut down if cooling is not needed. This can also happen if the motor is running at unnecessarily high speeds or if it is driven in an open circuit. However, when properly configured, motorized chillers are reliable, efficient liquid chillers for the entire range of industrial and air conditioning applications.

This series of water cooled screw compressor chiller adopts European high-efficiency screw compressors, which have their own advantages: high energy efficiency, low noise, high reliability, small footprint, easy installation, simple operation and high flexibility. They are widely used in surface engineering, medicine, chemical, metallurgy, leather, laser, electronics, injection molding, printing and other industries. There are too many models of this series of chiller. It can realize the perfect match for industrial applications.

The rated working condition of the cooling water required by the chiller is 30~35°C. The high water temperature and poor heat dissipation will inevitably lead to high condensation pressure. This phenomenon often occurs in high temperature seasons. The reason for the high water temperature may be: cooling tower failure, such as the fan is not turned on or even reversed, and the water distributor does not turn, which means that the temperature of the cooling water is high and rises rapidly; the external temperature is high, the waterway is short, and the amount of circulating water In this case, the cooling water temperature is generally maintained at a relatively high level, which can be solved by increasing the water storage tank.

2. The cooling water flow is insufficient and cannot reach the rated water flow:

The main performance is that the pressure difference between the inlet and outlet of the unit becomes smaller (compared with the pressure difference at the beginning of the system's operation), and the temperature difference becomes larger. The cause of insufficient water flow is the lack of water or air in the system. The solution is to install an exhaust valve at a high place in the pipeline to exhaust; the pipeline filter is clogged or too fine, and the water permeability is limited. Regularly clean the filter screen; the water pump is selected to be small and does not match the system.

3. Condenser scaling or blockage:

Condensed water is generally tap water, which is easy to scale when the temperature is above 30°C, and because the cooling tower is open and directly exposed to the air, dust and foreign matter can easily enter the cooling water system, causing the condenser to be dirty and blocked, and the heat exchange area is small , the efficiency is low, and it also affects the water flow. The performance is that the water pressure difference between the inlet and outlet of the unit and the temperature difference become larger, the temperature of the upper and lower parts of the condenser is very high when touched by hand, and the copper tube of the condenser liquid outlet is hot. The unit should be backwashed regularly, and if necessary, chemical cleaning and descaling should be carried out.

4. Too much refrigerant charge:

This kind of situation generally occurs after maintenance, and the performance is that the suction and discharge pressure and the balance pressure are high, and the operating current of the compressor is also high. Under the rated working condition, the air should be released according to the suction and exhaust pressure, balance pressure and operating current until it is normal.

5. The refrigerant is mixed with air, nitrogen and other non-condensable gases:

This kind of situation usually occurs after maintenance and the vacuuming is not complete. It can only be drained, re-evacuated, and re-charged with refrigerant.

6. False alarms caused by electrical failures:

Because the high-voltage protection relay is damp, poor contact or damaged, the electronic board of the unit is damp or damaged, and the communication failure causes false alarms. For this kind of false fault, the high-voltage fault indicator light on the electronic board is often off or dimly lit, the manual reset of the high-voltage protection relay is invalid, and the operating current of the measured compressor is normal, and the suction and discharge pressure are also normal.

7. The evaporation pressure is too low:

It may be that the evaporation pressure of the water-cooled chiller is too low due to insufficient refrigerant. Common reasons: Insufficient cooling water; less cooling load; throttle orifice failure (only makes the evaporation pressure low); the heat transfer tube of the evaporator is deteriorated due to scale and other pollution (only makes the evaporation pressure too low); Insufficient (only makes the evaporating pressure too low).

8. The oil pressure difference is too low:

If the compressor oil pressure is too low, the compressor will stop running. The common reasons are: the oil filter is clogged; too much refrigerant is mixed in the lubricating oil.

9. Oil temperature is too high:

If the oil temperature of the refrigeration compressor is too high, long-term operation will reduce the quality of the refrigeration oil and even carbonize the refrigeration oil. Common causes: the cooling capacity of the oil cooler is reduced; the supply of refrigerant for cooling the oil cooler is insufficient due to the blockage of the refrigerant filter.

10. Main motor overload:

Unbalanced power supply phase voltage; large power line voltage drop;

The introduction of various industrial chillers and common fault handling are relatively complicated. Generally, specific analysis is made according to the specific problems of the situation. It is recommended to judge according to the actual situation or contact the industrial chiller manufacturer to solve the problem.

The compressor is the core component of the industrial chiller. Although the brand compressor we use has a long life, in actual use, if the user does not carefully maintain and maintain the compressor of the industrial chiller, it will also cause problems. Failures of varying degrees will seriously affect the performance of the entire industrial chiller. Preventing compressor failure in industrial chillers is therefore critical to maintaining reliable operation and minimizing downtime. Here are some effective measures to prevent compressor failure:
1. Routine inspections: During the use of industrial chillers, you need to always pay attention to the problem of compressor operating noise. If the noise increases significantly, according to the experience introduced by the factory cooler factory, shutdown inspections need to be completed in a timely and effective manner. , on the basis of ensuring normal operation, complete the maintenance work of industrial cooler compressors. Note: Once the compressor makes noise, you need to be more vigilant. Often small problems can cause complex and serious faults in the later period, such as compressor fluid shock.

2. Regular maintenance: Implement a comprehensive maintenance plan for the chiller system, including routine inspections, cleaning, lubrication and component inspections. Follow the manufacturer's recommendations for maintenance intervals and procedures.

3. Monitor the refrigerant level: Make sure the chiller has the correct refrigerant charge. Low refrigerant levels can cause the compressor to work harder, leading to overheating and potential failure. Regularly check and maintain proper refrigerant levels according to system specifications. During use, the specific values of the pressure gauge of the industrial chiller need to be paid attention to at any time. If there is a large-scale abnormality, careful inspection is required at this time. The specific inspection method can be completed according to the relevant methods introduced by the domestic industrial chiller manufacturer. Check the process to avoid pressure problems that affect the specific working efficiency of the compressor of the industrial chiller, causing an increase in electricity consumption and increasing the energy consumption of the industrial chiller. Note: Chiller pressure gauge, including high pressure pressure gauge, low pressure pressure gauge, etc.
4. Clean condenser and evaporator coils: Dirty coils will reduce heat transfer efficiency, resulting in increased compressor workload and higher operating temperatures. Clean your condenser and evaporator coils regularly to remove dirt, dust and debris that has accumulated on their surfaces.

5. Maintain proper oil level and quality: Compressor oil lubricates and cools the compressor’s internal components. Monitor oil levels regularly and refill or replace oil as needed. Make sure the oil used is of the type and quality recommended for the cooling system.

6. Check the electrical connections: Loose or faulty electrical connections may cause excessive current, causing the compressor to overheat and malfunction. Regularly check and tighten electrical connections to ensure electrical components are intact.

7. Monitor operating parameters: Install a monitoring system to continuously monitor key parameters such as compressor discharge temperature, suction pressure, and motor current intensity. Set alerts or alarms to notify operators of any abnormal conditions so timely intervention and corrective measures can be taken.

8. Adequate airflow and ventilation: Make sure there is proper airflow and ventilation around the chiller. Poor airflow can cause the compressor to overheat. Remove any obstructions and regularly check and clean the air filter to maintain optimal airflow.

9. Avoid frequent cycles: Try to reduce the frequency of starting and shutting down the chiller, as frequent cycles will put extra pressure on the compressor. Maintain as stable operating conditions as possible to reduce compressor workload.

10. Train personnel: Provide appropriate training to chiller operators and maintenance personnel on chiller operation, maintenance procedures and troubleshooting techniques. Well-trained personnel can detect potential problems early and take appropriate measures to prevent compressor failure.

By implementing these measures, you can significantly reduce the risk of compressor failure and extend the life of your industrial chiller system. Additionally, it is recommended to consult the industrial chiller manufacturer’s guidelines and recommendations for specific maintenance procedures and precautions.

Although most of the various industrial chillers produced in my country are imported compressors, which have a long service life, but in actual use, if the user does not carefully maintain and maintain the compressors of the industrial chillers, Different degrees of failures will also occur, seriously affecting the performance of the entire industrial chiller. There are several effective measures to prevent industrial chiller compressors from malfunctioning, including:

Regular maintenance: Regular maintenance of the compressor, including cleaning and replacing parts, can prevent malfunctioning due to wear and tear.During the use of industrial chillers, it is necessary to pay attention to the noise of the compressor at all times. If the noise increases significantly, according to the experience introduced by the industrial cooler factory, it is necessary to complete the shutdown inspection in a timely and effective manner at this time to ensure normal operation. On the basis of this, complete the maintenance work of industrial cooler compressors. Note: Once the compressor makes noise, you must be more vigilant, often small problems will cause complex and serious failures in the later stage, such as compressor liquid shock.

Measure the operating temperature: During the operation of the industrial chiller, it is necessary to measure the specific operating temperature of the compressor of the industrial chiller by hand or equipment at any time. If the temperature is too high, it means that the industrial chiller is in an overloaded state. At this time, it is necessary to measure the current and voltage. In order to achieve the purpose of fault detection, so as to ensure that the industrial chiller compressor is in an absolutely safe operating state, reach a suitable operating temperature, and complete the entire operating process. Note: If the temperature of the compressor is too high, it may also be caused by too little fluorine, too small compressor power, too long capillary, poor condensation effect, temperature control failure, and lack of oil in the compressor. The damage is very serious, so special attention must be paid.

Clean condenser coils: The condenser coils of the chiller should be kept clean to ensure that the compressor is not overworked due to reduced heat transfer.Pay attention to the pressure gauge,if the high pressure gauge is very high, please check the condenser coil and clean it when necessary.

Proper refrigerant charge: The compressor should have the correct refrigerant charge to ensure that it is not working harder than necessary, which can cause it to malfunction.

Monitoring of operating conditions: The operating conditions of the compressor, including temperature and pressure, should be monitored to ensure that it is not overworked or subjected to conditions that can cause malfunctioning.

Training of personnel: Proper training of personnel in charge of operating and maintaining the compressor can prevent mistakes that can cause the compressor to damage.
