Optimizing a chilled-water hydronic system
Case study for Hydronic system control optimization in HVAC system


A leading technology R&D institution in Taiwan, the Industrial Technology Research Institute (ITRI), was facing some HVAC challenges; the requirement for the room temperature of their laboratories to be more accurately controlled and to reduce energy consumption after the installation of a Magnetic Bearing Centrifugal Chiller.

The most straightforward way to save energy is to renovate the HVAC system with new highly efficient equipment, however, what if instead we could optimize the existing equipment to operate in a highly efficient condition?

With the help of our hydronic experts, a full system audit was performed to determine how to tackle these challenges and optimize the hydronic system to run the full air conditioning system in the required energy-efficient condition.
