21 November, 2016

Operation optimization and fundamental upgrading of the central building air conditioning system is summarized as follows:

  • Flow adjustments and piping malfunctions resolving via new variable speed pump system.
  • Complete installation on the roof of the building of two new air cooled chillers of high performance (type High Efficiency), replacing the old chillers (refrigerant R-22) .
  • Implementation of the appropriate air-conditioning management control system.

The new cooling ensured:

  • smooth operating conditions, fully automated
  • reduced maintenance requirements and costs
  • full control and monitoring via the central automation system installation
  • air-conditioning energy saving of more than 35%.

Namely, the replacement of the old chillers (refrigerant R-22) with simultaneous substantial improvement of cooling water distribution and appropriate management system adaptation led to optimum operating result with overall payback time of investment of 3.5 years.
