The cleaning method for the steam-type lithium bromide water chiller unit is as follows:
Shut down the unit: First, turn off the power and water supply to the steam-type lithium bromide cooling unit, ensuring the unit is completely stopped.
2. Clean Heat Exchanger: Use a soft brush or high-pressure water to clean the exterior surface of the heat exchanger, removing dirt and dust.
3. Clean Condenser: Use a specialized cleaner and follow the instructions provided. Typically, dilute the cleaner and spray it onto the condenser, then rinse thoroughly with clean water.
4. Clean the Evaporator: Disconnect the cooling water from the evaporator, drain it completely, and then clean the evaporator with a cleaning agent. The cleaning agent will circulate through the water system to remove internal dirt from the evaporator. After cleaning, rinse thoroughly with clean water.
5. Replace lubricating oil: Drain the old oil and then refill with new lubricant according to the equipment specifications and manufacturer's instructions.
6. Engine Start-up: After cleaning, inspect the connections of all components for proper alignment. Then, start the engine according to the engine operation manual's instructions and gradually adjust operating parameters to ensure normal engine operation.
Please ensure safety during the cleaning process of the unit, with qualified technicians handling the operation to prevent accidents. Also, follow the instructions for the cleaning agent to avoid damaging the unit. In case of special circumstances or issues, consult the unit's maintenance personnel or the manufacturer's technical support.

The cleaning method for the LG lithium bromide unit is as follows:
1. Shutoff Unit: Firstly, ensure the unit is turned off and the power is disconnected to ensure operational safety.
2. Cleaning the Condenser: Cleaning the condenser is a crucial step in maintaining a lithium bromide unit. Use water and detergent to clean the condenser. First, rinse the condenser surface with water, then spray the detergent onto the surface. Next, scrub the condenser surface with a soft brush or sponge, focusing especially on the exhaust and gas sides. Finally, rinse the condenser with clean water to ensure the surface is clean.
3. Clean the Evaporator: Before cleaning the evaporator, it is necessary to first remove the refrigerant inside. Then, use a mild cleaning solution to wash the evaporator surface, which can be evenly sprayed with a sprayer. Next, clean the surface with a soft brush or sponge. Finally, rinse the evaporator with clean water to ensure the surface is clean.
4. Clean filters and ducts: Remove the filter and clean it with water and detergent, then rinse thoroughly and let it dry. Simultaneously, clean the ducts, removing dust and dirt inside.
