Troubleshoot your air conditioning problems with this guide from trane.
Water cooled ac unit troubleshooting.
This type of coaxial water cooled condenser is designed for use with refrigeration and air conditioning condensing units where space is limited.
Be sure to clear away any tall grass sticks or leaves that may be surrounding your outdoor unit.
Ice on refrigerant lines.
Water is piped through the inner tube.
If it s clogged it can reduce cooling and even damage the system.
If the refrigerant level is low it usually means it was either undercharged at installation or it has a leak.
Refrigerant is piped through the tube that encloses the inner tube.
Here are some facts that you should know about water cooled condensers.
The thru hull allows your boat s ac unit to draw raw water from the sea.
To deal with condensate problems please see air conditioner leaks water below.
Low airflow from air vents.
The refrigerant flows in the opposite direction than the water see fig.
Inadequate cooling hot cold spots ac struggles to reach set temperature.
But it is an ideal location for critters and debris to accumulate.
Water can also puddle around the unit or flood the area.
Ac problems caused by a dirty filter.
Your outdoor cooling coil may be clogged or blocked debris can easily stick to the inlet side of the cooling coil in your unit.
The colder the water the more efficient the cooling but most air conditioners will work fine to water temps into the 80 degree range sometimes warmer.
The thru hull lets water in and out of the ac unit.
The cooling tower should provide water that is about 7 degrees warmer than the outdoor wet bulb so a 78 degree wet bulb should yield 85 degree water to the condenser.
If your system is low on refrigerant or has a dirty filter the system may freeze up when it s working.
Air conditioner problems are not cool low refrigerant equals low efficiency while air conditioning troubleshooting uncovers an under performing unit that can be the result of low refrigerant.
Don t risk water damage from your air conditioner leaking water on the floor or ceiling.
Water leaking from your ac.
If your central air conditioner will not cool but you can hear it running it may just need to be cleaned.
How to open check clean the outdoor ac compressor.
Pressure equals heat so to cool the gas on the downstream side of the compressor it s run through a raw water cooled condenser which returns the refrigerant to a liquid state.
