Cleaning of refrigeration unit systems
Thread Content
Our factory is equipped with a dual-compressor refrigeration unit; the compressors are of semi-hermetic type, the refrigerant used is R22, and the coolant is a 45% ethylene glycol solution. During operation, the screw got stuck, which caused the motor to burn out. The impurities and debris resulting from this burnout entered the system, leading to clogging of the filter for the newly replaced compressor oil; as a result, it was necessary to replace the refrigerant oil again. Dear sea friends, apart from the replacement of the refrigeration oil, are there any other methods for cleaning the systems in a refrigeration unit? I would appreciate your guidance.
For the cleaning of refrigeration unit systems, in addition to replacing the refrigerant oil, the following methods can also be considered: 1. System flushing: This involves removing dirt and impurities from inside the system; a specialized cleaning agent for refrigeration unit systems can be used, following the instructions provided for its use. 2. Filter replacement: Replace the filter in the system with a new one to remove impurities and dirt. 3. High-pressure cleaning: Using high-pressure water or gas cleaning systems to clean the pipes and equipment inside, flushing out impurities and dirt. 4. Chemical cleaning: Using specific chemical solutions to clean the interior of the system in order to remove impurities and dirt. It should be noted that before cleaning the system, the power to the unit must be turned off first, and the refrigerant and coolant in the system must be drained to ensure safe operation. At the same time, select appropriate cleaning methods and cleaners, and follow the instructions for using them to avoid causing any adverse effects on the system. Additionally, after cleaning, the refrigerant and coolant must be refilled, and the system must be tested and adjusted to ensure its proper operation. .
If high-pressure water is used for cleaning, how can it be ensured that there is no residual water in the system?
