How to deal with the leakage of air-cooled chiller refrigerant

Jul 11, 2023

Refrigerant leakage is a common failure of air-cooled chillers. To deal with refrigerant leakage of chillers, we must first understand the cause of refrigerant leakage and find out the cause of the failure to reduce losses caused by refrigerant leakage. If you have a refrigerant leak in an air-cooled chiller, it is important to address it promptly to prevent further damage and ensure the efficient operation of the system. Here are some steps to deal with a refrigerant leak:

Identify the Leak: Use a refrigerant leak detector or bubble solution to locate the source of the leak. Common areas where leaks occur include connections, fittings, valves, and joints.

Ensure Safety: Make sure to follow proper safety procedures when dealing with refrigerants. Wear protective gear such as gloves and goggles, and work in a well-ventilated area.

Repair the Leak: Depending on the size and location of the leak, you may be able to repair it yourself or contact a professional HVAC technician. Common repair methods for air-cooled chillers include tightening fittings, replacing faulty valves or gaskets, or soldering joints.

Evacuate and Recharge Refrigerant: If the refrigerant has leaked significantly, it may be necessary to evacuate the remaining refrigerant from the system using a recovery machine. Once the leak is repaired, vacuum the system to remove any moisture or air, and recharge it with the appropriate amount of refrigerant as specified by the manufacturer.

Test for Leaks: After the repair and recharge, test the system for any remaining leaks. Use a refrigerant leak detector or soap bubbles to carefully check all connections and areas that were repaired.

Monitor and Maintain: Regularly monitor the chiller system for any signs of leakage, such as reduced cooling capacity or unusual noises. Perform routine maintenance, including checking and tightening fittings, cleaning coils, and replacing worn-out parts, to prevent future leaks.
