Air Cooled Screw Chiller User Guide

An air cooled screw chiller is a type of chiller that utilizes air to condense the refrigerant, with the refrigeration cycle powered by a screw compressor. This chiller is primarily used in air conditioning systems and industrial cooling applications, providing efficient chilled water to meet the cooling demands of large factories, office buildings, and commercial complexes.

Installation Guidelines for Air Cooled Screw Chiller

Location Selection

The screw air cooled chiller should be installed in an outdoor area with good ventilation and free from strong corrosive gases. Sufficient space around the unit must be ensured for heat dissipation and future maintenance.

Foundation Requirements

The chiller must be installed on a solid, level foundation to ensure stable operation, reduce vibrations, and minimize noise.

Electrical Connections

The electrical wiring should comply with national electrical safety standards and must be installed by a qualified electrician to ensure proper connections, preventing leakage or short circuits.

Operating Guidelines for Air Cooled Screw Chiller

Pre-Startup Check

Before starting the screw air cooled chiller, check that the chilled water pipeline is unobstructed, refrigerant levels are adequate, the power supply voltage is stable, and the control system is functioning correctly.

Normal Startup

Press the start button on the control panel to activate the unit. Monitor parameters such as pressure, temperature, and current to ensure the system operates within the normal range.

Operation Monitoring

Regularly monitor the operating parameters of the chiller. If abnormal sounds, vibrations, or irregular readings are detected, shut down the unit immediately for inspection.

Daily Maintenance for Air Cooled Screw Chiller

Cleaning and Maintenance

Periodically clean the condenser's surface to remove dust and debris, ensuring efficient heat dissipation. The fan blades should also be kept clean to avoid obstruction of airflow.

Lubrication System Check

Ensure the screw compressor's lubricating oil remains at the proper level. Regularly replace the lubricating oil and filter to maintain smooth compressor operation.

System Inspection

Regularly check refrigerant pressure and monitor for leaks to ensure the system's sealing is intact, preventing refrigerant loss that could affect cooling efficiency.

Electrical Equipment Inspection

Inspect electrical components and connections to prevent poor contact or aging, ensuring safe operation.

Conclusion

The air cooled screw chiller, as an efficient and energy-saving refrigeration device, requires strict adherence to installation, operation, and maintenance procedures to ensure long-term, stable performance. Through scientific management and regular maintenance, the chiller's lifespan can be significantly extended, improving the overall performance of the cooling system and providing a more comfortable and efficient environment for industrial and commercial users.
