Installation of SavaControls to the compressors resulted in

  • SavaWatt Controls refrigeration controls giving a 15% energy saving.
  • C02 Reduction 11,216kg
  • Project payback under 2.0 years

St Andrews is Scotland’s first university and the third oldest in the English speaking world, founded in 1413. Nearly all the refrigeration equipment in the University had poor efficiency. A program of installation of SavaWatt refrigeration motor controls was started with the residences kitchen and student fridges, giving a 15% energy saving. This was successful, so all scientific fridges (including the –80C freezers) were targeted. No problems were encountered, and now every suitable fridge or freezer in the University has been modified. Finally all air conditioning units which do not have R22 (to be phased out) or inverter control (already energy efficient) have been modified.
