RCC11 Open- and closed-loop control

RCC11 Open- and closed-loop control

Anyone wishing to work in refrigeration or air-conditioning needs to know all about the many electrical and control components, as well as the systems themselves. The course teaches aspects of electrical engineering, open- and closed-loop control, as well as some drive technology in a way that is practical and specific to refrigeration and air-conditioning.

Standards specifically applicable to the circuits used in construction of refrigeration systems are observed and the relevance to common practice is underpinned by using technical documentation from a variety of manufacturers.

The following training contents are covered:

  • Generating a control voltage
  • Circuits with primary and auxiliary contactors
  • Circuits with time-delay relays
  • Thermostats and pressures switches in contact control systems
  • Safety chain for refrigeration and air-conditioning control systems
