A variety of mechanisms and applications is a great challenge to the service. Luckily, there are some fundamental problems all of these condensing units are common:
Compressor efficiency.
Condenser efficiency.
Refrigerant charge.
Refrigerant purity.
Electrical circuit problems.
water-cooled condensers different problem. Rising water temperatures, as he passes through the condenser should be limited. Water consumption should be adjusted so that the temperature does not exceed 15 grow.
Water passageways should be clean. If a device with a belt drive belts should be checked and flaky.
Strongly metallic pounding sound occurring regularly in the compressor need to understand. Check the oil level is low or worn parts. The amount of refrigerant in the system should be checked carefully. Motor control should be checked to determine whether it is travel freely. Pointif any must be clean. Dirty or pitted contact points should be replaced...
