Refrigeration Control Systems Come of Age

January 2013
Food Logistics;Jan/Feb2013, Issue 143, p16
The article discusses the effects of aging refrigeration control systems and the benefits of upgrading them. According to the authors, aging refrigeration controls often cause unstable suction and head pressures, inability to trim fans and pumps through variable frequency drive (VFD) controls, and multiple partially loaded compressors. The authors emphasize that modern refrigeration control systems allow users to generate trend analyses, alarm logs, and energy management data.
