Compressors, often referred to as the heart of the refrigeration cycle, are typically the largest energy consumers. Condensers fill the role of rejecting heat from a refrigerated space to the atmosphere by condensing the refrigerant.
With a switch from individual condensing units to parallel-compressor systems, one cheese-processing facility realized lower installation costs, reduced energy consumption and improved preservation of food products, among other benefits.
Parallel-compressor systems for refrigeration made their debut in the grocery store industry in the late 1980s, providing an alternative to the traditional split systems, or individual condensing units, used throughout commercial and industrial applications.
To achieve capacity control in reciprocating compressors, Bitzer offers refrigeration engineers two solutions: speed control provided by CRII mechanical capacity control or Varispeed with integrated frequency inverter.
Tube failure continues to be the leading cause of unplanned downtime in thermal power plants. Leaks occur in the tubes due to tube failures such as bending, cracking, bulging or wear. Reasons for the failures include ash, overheating, corrosion and erosion.
The OSHA Technical Manual (TED 01-00-015) — intended to provide technical information about workplace hazards and controls to the Occupational Safety and Administration’s compliance safety and health officers — provides a wealth of information about industrial hazards.
