If a condenser becomes dirty or fouled, less heat transfer can take place from the refrigerant to the surrounding ambient space. Dirty condensers are probably the most common problem found during a service call next to dirty filters. It is hard to say which one is the most devastating to a system. List below are some the results of a dirty condenser.n
- Compressor amperage begins to exceed its design limits shortening the life of the compressor.n
- Discharge gas temperature can reach critical levels causing a breakdown of the refrigerant and oil lead to compressor or system failure. This level is about 225degs.n
- The suction gas coming back to the compressor is no longer sufficient to cool the compressor motor, again leading to compressor failure.n
- The condensers air discharge temperature is greatly elevated and if the condenser fan motor relies on it for cooling, it may fail as well.n
- Flash gas reaching the metering device causing erratic operation, high Superheat and lower net refrigeration effect. n
