A guide to common problems and solutions for yacht air conditioning
Read Time:6 Minute, 40 Second
Yacht air conditioning is an important equipment to ensure the comfort on board, especially in hot summer or humid marine environment, a good air conditioning system can provide pleasant cabin temperature and humidity. However, yacht air conditioning may have various faults during long-term use, affecting normal operation. If you don't understand the common problems and their solutions, it will not only affect the comfort of the yacht, but also cause more serious equipment damage. This article will explore the common faults of yacht air conditioning in depth and provide detailed solutions to help yacht users better maintain and maintain the air conditioning system.
1. Yacht air conditioning does not refrigerate or has poor refrigeration effect
Common causes
Insufficient or leaking refrigerant: After long-term use, the yacht air conditioner may cause insufficient refrigerant due to leakage, affecting the refrigeration effect.
Condenser or evaporator dirty blockage: Dust and scaling of the condenser or evaporator will reduce the heat exchange efficiency, thereby affecting the refrigeration effect.
Air conditioning filter blockage: Too much dust on the air filter will affect air circulation and reduce the refrigeration effect.
Compressor failure: The compressor is the core component of the yacht air conditioner. If it is damaged or aged, it will directly affect the refrigeration function.
Seawater cooling system failure (applicable to water cooling system): The seawater pump is blocked and the water inlet is blocked by dirt, which may cause the air conditioner to fail to dissipate heat normally and affect the cooling effect.
Solution
Check the refrigerant pressure. If the pressure is too low, it is necessary to add refrigerant and check the leak point. After repair, refill it.
Clean the condenser and evaporator regularly. You can use professional detergents or high-pressure water guns to clean them to ensure heat exchange efficiency.
Clean or replace the air conditioner filter. It is recommended to check it once a month and replace it regularly according to the usage.
Check whether the compressor is working properly. If the compressor is damaged, you need to contact professional technicians for repair or replacement.
Clean the seawater cooling system, check whether the seawater pump is working properly, remove debris in the pipes, and keep it unobstructed.
2. The yacht air conditioner cannot start or trips frequently
Common causes
Power failure: The yacht air conditioner may fail to start due to unstable power supply voltage, line failure or circuit breaker.
Damaged starting capacitor: Damaged starting capacitor will cause the compressor to fail to start.
Compressor overload protection: When the yacht air conditioner runs for too long or the ambient temperature is too high, the compressor may trigger the protection mechanism due to overheating.
Short circuit or overload: Short circuit or overload may cause the air conditioner to trip.
Solution
Check whether the power supply voltage is stable and ensure that the yacht's generator or shore power system is powered normally.
Test whether the starting capacitor is damaged. If damaged, replace it with a new capacitor.
Let the compressor rest properly. If it stops due to overheating protection, it can be restarted after cooling down, and avoid long-term high-load operation.
Check whether the line has short circuit or aging problems, and repair the faulty line in time.
3. The yacht air conditioner is too noisy
Common causes
Loose or damaged fan blades: Deformation, looseness or jamming of fan blades will produce abnormal noise.
Compressor failure: Loose or aging of internal parts of the compressor may cause increased operating noise.
Pipeline vibration or resonance: When the pipeline of the yacht air conditioner is running, if it is not fixed stably, it may produce resonance noise.
Abnormal sound of seawater pump (water cooling system): Damage to the impeller of the seawater pump or jamming of debris may cause noise.
Solution
Check whether the fan blades are normal. If deformed or damaged, they need to be adjusted or replaced.
Check the operating status of the compressor. If abnormal vibration or noise occurs, ask a professional to check, repair or replace the compressor.
Fix the air conditioning pipes and use shock-absorbing rubber pads or fasteners to fix the pipes to reduce vibration and resonance.
Clean up the debris inside the seawater pump. If the impeller is damaged, replace it with a new part.
4. The yacht air conditioner has a peculiar smell
Common causes
The air filter has not been cleaned for a long time: the air filter is dusty and moldy, causing the air blown out by the air conditioner to have a peculiar smell.
Condensate accumulation: Condensate discharge is not smooth or accumulates for a long time, which will breed bacteria and mold and produce peculiar smell.
Seawater cooling system pollution: In the water cooling system, the inside of the seawater pump or heat exchanger has not been cleaned for a long time, which may breed marine life or bacteria, causing peculiar smell.
Solution
Clean the air filter regularly, rinse with clean water or use disinfectant to clean it, and keep the filter clean.
Clean the condensate drainage system to ensure that the drainage pipes are unobstructed and avoid condensate accumulation.
Use air conditioning cleaner and spray antibacterial spray regularly to eliminate mold and bacteria.
Clean the seawater cooling system to prevent the attachment of organisms in the seawater and cause odor.
5. Abnormal heating function of yacht air conditioner (applicable to dual-purpose air conditioners for hot and cold)
Common causes
Failure of reversing valve: When the yacht air conditioner switches to heating mode, if the reversing valve is stuck or damaged, it may not be able to provide heat normally.
Insufficient refrigerant: Insufficient refrigerant pressure will affect the heating capacity of the heat pump mode.
Damage to the heating element (some models): If the yacht air conditioner relies on an electric heater for auxiliary heating, damage to the element will cause the heating function to fail.
Solution
Check whether the reversing valve switches normally. If a problem is found, contact a professional maintenance personnel to replace it.
Detect the refrigerant pressure. If the pressure is insufficient, the appropriate type of refrigerant needs to be filled.
Check whether the electric heating element is damaged. If there is a fault, replace the new heating element.
6. How to prevent yacht air conditioner failure?
In order to reduce the failure rate of yacht air conditioners, the following preventive measures are recommended:
Regular maintenance and cleaning: Deep cleaning every 3-6 months, including filters, evaporators, condensers and pipes.
Check the circuit system regularly to ensure the safety of the line and avoid short circuit or overload.
Monitor the refrigerant pressure, replenish it regularly and check for leaks.
Pay attention to the use environment, avoid long-term high-load operation, and properly turn off the air conditioner to let the system rest.
