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.

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.
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.

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.
