Q: What is the working principle of RSW seawater cooled chiller?
A: The unit compresses the refrigerant through the compressor, and the refrigerant exchanges heat with seawater in the evaporator. After absorbing heat, it dissipates heat through the condenser to achieve seawater cooling.

 

Q: In what fields is this unit mainly used?
A: It is mainly used in marine engineering, ship air conditioning, aquaculture and other fields to provide a cold source for equipment or environments that require cold water.

 

Q: How to clean the evaporator of RSW seawater cooled chiller?
A: First shut down and cut off the power, rinse the inside of the evaporator with a special cleaning agent to remove scale and impurities, and then rinse with clean water to ensure heat exchange efficiency.

 

Q: What environmental factors should be paid attention to when installing the unit?
A: When installing, avoid highly corrosive environments, ensure good ventilation, stay away from heat sources and vibration sources, and the foundation must be flat and solid.

 

Q: What components need to be checked for daily maintenance of the unit?
A: Daily maintenance requires checking the compressor, fan, filter, valve and other components to check for abnormal sounds, leakage or blockage.

 

Q: Does the unit's condenser need to be replaced regularly?
A: If the condenser is properly maintained, it generally does not need to be replaced regularly, but if it is severely corroded or leaking and cannot be repaired, it needs to be replaced.
