Common Troubleshooting Of Explosion-Proof Air Conditioners

1. Troubleshooting a Non-Operational Explosion-Proof Air Conditioner

i. Verify the power supply is active with a voltage range of 220V (380V) ±10% (testable via a multimeter or pen tester).

ii. Assess the battery in the remote control for sufficient current (check for a clear LCD display).

iii. Ensure all parameter settings, like operational status and temperature, are correctly configured.

iv. Scan for potential electromagnetic disturbances near the indoor unit, such as fluorescent lights, that might interfere with the remote’s signal.

2. Addressing Insufficient Cooling in Explosion-Proof Air Conditioners

i. Confirm that all doors and windows are securely closed and identify any new internal heat sources.

ii. Ensure the filter is clean and that both the indoor and outdoor vents are unobstructed and free from circulation issues.

iii. Verify that settings, particularly fan speed, are correctly adjusted to high for maximum cooling.

iv. Evaluate the outdoor unit for optimal heat exchange conditions, checking for impacts from direct sunlight or adjacent air conditioner units.

3. Resolving Dripping or Leaking in Explosion-Proof Air Conditioners

i. Inspect the drain pipe for any twists, flattening, or breakages.

ii. Check that the drain outlet is above water level, not submerged.

iii. Confirm the integrity of the connection between indoor and outdoor units, wrapping any exposed sections with high-quality insulating material.

4. Mitigating Excessive Noise in Explosion-Proof Air Conditioners

i. Determine whether the air conditioner is the noise source.

ii. Note that noises from internal plastic components during start-up or shut-down due to temperature-induced expansion or contraction are normal.

iii. Check that both the indoor and outdoor units are firmly fixed to their respective walls.

iv. Ensure that connecting pipes, both indoor and outdoor, are securely fastened and not in contact with other equipment or objects.
Upon start-up or shut-down, the refrigerant’s initial loud airflow noise before equilibrium is standard. Heat pump air conditioners are widely preferred for their efficiency in both cooling and heating modes. Here are some scenarios you might encounter:

i. Upon start-up, if the outdoor unit activates for heating while the indoor unit remains idle, this is standard cold air prevention. The indoor unit will be operational once it has stored sufficient heat.

ii. During colder conditions, it’s normal for the indoor unit to pause for a few minutes after a heating cycle. This pause allows for defrosting as frost accumulation on the outdoor unit’s heat exchanger can hinder further heat transfer.

iii. If fan speed and guide vanes don’t always respond to remote control commands, this is due to the air conditioner’s microcomputer storing various fixed operation modes to ensure optimal performance under specific conditions.

For safety, users are urged to connect the air conditioner to a dedicated circuit due to its high power consumption. This also helps reduce interference with other household appliances.

According to electrical safety standards, the equipment must have a proper grounding device. Never connect the ground wire to gas pipes; instead, utilize the building’s steel reinforcement as a grounding electrode. Furthermore, the circuit should be equipped with a fuse of the appropriate value. As air conditioners are complex electromechanical products, a variety of issues may arise. If you’re unable to resolve a problem through initial diagnostics, it’s crucial to contact professional technicians for repair to avoid further risks and ensure safe operation.
