No, it is not normal for droplets of water to come from the connection valve or refrigerant pipes of a split AC system. If you are noticing water leakage from these areas, it could indicate a problem that requires attention. Here are a few possible causes for water leakage in those locations:
Condensate Drainage Issue: The most common cause of water leakage in a split AC system is a problem with the condensate drainage. Air conditioners produce condensate as a byproduct of the cooling process, and it is meant to be collected and drained away. If the condensate drain line is blocked or improperly installed, water may accumulate and leak from the connection valve or refrigerant pipes.
Improper Installation: Incorrect installation of the AC unit can lead to water leakage. If the connection valve or refrigerant pipes were not properly sealed during installation, it could result in water escaping from those areas. Inadequate insulation around the pipes can also cause condensation to form and drip.
Refrigerant Leak: While refrigerant leaks are less common causes of water leakage, they can potentially lead to moisture accumulation near the connection valve or refrigerant pipes. If there is a refrigerant leak in the system, it should be addressed promptly, as it can impact the cooling efficiency and overall performance of the AC unit.
It's important to have a qualified HVAC technician inspect and diagnose the issue if you are experiencing water leakage from the connection valve or refrigerant pipes. They can identify the specific cause and provide the necessary repairs or adjustments to resolve the problem.
