Every refrigeration system has a condenser, and the condenser is a critcial system component. A sound preventive maintenance program will provide long equipment life and trouble-free operation.
Refrigeration systems are used around the world for all kinds of applications. From cooling or storing produce to keeping a building cool on a hot summer day, refrigeration systems remove heat from people, places and things. Every refrigeration system has a condenser, and the condenser is a critical system component (figure 1). It fills the vital role of rejecting heat from a refrigerated space to the atmosphere by condensing the refrigerant. Several different condenser types exist, each with its own features and benefits.
Air-Cooled Condensers. Most often found where water is not available, in an air-cooled condenser, a fan blows air over a coil containing refrigerant. Air movement over the coil cools the refrigerant and allows condensation to occur. Air temperature determines the refrigerant's temperature. Energy requirements tend to limit this type of condenser to smaller systems.
