220V Water Cooled Water Chiller 5KW - 300KW Small Water Chiller Unit R22 / R407C

Product Specification

Water Cooled Chiller System Shell and Tube Condenser R22/R407C Refrigerant Microprocessor Controller 5-300KW

The water-cooled chiller is a refrigeration equipment that uses water as the cooling medium. It mainly includes a compressor, a condenser, an expansion valve, and an evaporator. Water-cooled chillers generally need to be equipped with a cooling water tower and an insulated water tank for use together. Compared with air-cooled chillers, water-cooled chillers have better cooling efficiency and higher accuracy of outlet water temperature.

Advantages and Disadvantages:

Advantages:

• High cooling efficiency, suitable for high-power, continuous operation scenarios.
• Low operating noise, suitable for noise-sensitive environments.
• Longer life (lower condensing temperature, less compressor load).

insufficient:

• Depends on cooling water system, with high initial investment.
• Water quality issues (such as scale and algae growth) need to be addressed.
• Limited use in water-scarce areas.

Industrial Chiller Specification:

Common faults of water-cooled chillers and their troubleshooting methods include:

Power supply problem: If the chiller does not start or the indicator light is off, it may be due to abnormal voltage or a blown fuse. The solution is to check the power supply to ensure three-phase balance and replace the blown fuse or transformer.

Compressor problem: The compressor continues to run but the cooling capacity is insufficient, which may be due to overload or unclean condenser. The solution is to reduce the load, clean the condenser or replace the damaged fan. If the compressor fails, it may be a coil short circuit or open circuit, and a matching compressor needs to be replaced.

1. Cooling water problem: Insufficient cooling water flow or high temperature will affect the cooling effect. The solution is to check whether the water pump is blocked, increase the cooling water flow or reduce the water temperature. If the cooling water is not turned on, it will also cause a high-pressure alarm. The solution is to open the water valve.
2. Condenser problem: The condenser copper tube has a lot of scale and a small diameter, which will lead to poor heat dissipation. The solution is to clean the condenser copper tube.
3. Refrigerant problem: Insufficient refrigerant will cause a low-pressure alarm. The solution is to check for leaks and add refrigerant. A clogged filter can also cause a low pressure alarm. The solution is to remove or replace the filter.

‌Other common faults‌: including evaporator freezing, water pump failure, abnormal noise increase, abnormal control panel display, etc. Solutions include thawing the evaporator, repairing or replacing the water pump motor, cleaning foreign objects in the water pump and circulating water pipes, checking and repairing the control panel, etc.

‌Maintenance recommendations‌: Clean the condenser regularly to keep the surface clean, ensure good heat dissipation, extend the service life of the chiller and improve overall operating efficiency. In addition, check the cooling water system regularly to ensure its normal operation and avoid failures caused by cooling water problems. ‌

Working Principle:

The working principle of the water-cooled chiller is to compress the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas through the compressor, and then radiate the high-temperature and high-pressure gas through the condenser to condense it into a high-pressure liquid, and then pass the expansion valve to make the high-pressure liquid It expands into a low-pressure liquid and flows into the evaporator to complete the refrigeration cycle.

In the water-cooled chiller, water is used as the cooling medium, and is connected to the cooling equipment through the water pipeline, and the refrigerant gas after heat dissipation absorbs heat and turns it into a low-temperature and low-pressure gas, thereby realizing refrigeration.

Application Industry:

It is widely used in pharmaceutical, chemical, food, grease, coating, electroplating, cold storage, plastic, chemical fiber, commercial concrete, laser, purification workshop, mechanical processing and other industries. It can precisely control the temperature required by modern industrial manufacturing, greatly improving efficiency and product quality. JIALIS chiller is easy to operate, reasonable in design and superior in quality, with more than 100 models, it is the best choice for modern industrial refrigeration.

Packing and Shipping:

Air-cooled chillers are packaged and shipped in standard plywood wooden boxes. All components are secured and protected with a film, and the unit is then placed on a pallet for easy transport. And affix the shipping mark information label on the wooden box to ensure correct delivery.

Water-cooled chillers are suitable for scenarios with high requirements for cooling efficiency, long operating time and water system conditions, but attention should be paid to water quality management and regular maintenance. When selecting a model, it is necessary to comprehensively evaluate cooling requirements, environmental conditions and long-term operating costs, and consult professional engineers when necessary.
