  1. Variable Refrigerant Flow (VRF)

As technology is evolving and requirements are changing. In the Variable Refrigerant Flow (VRF) sector, different people have new definitions and requirements for space and air. Architectural spaces are quietly changing and this impose new challenges to cooling down space. In the modern era of rapid development, we have to face diverse architectural design and requirements. What can a VRF do to meet the requirements of a constantly changing design scheme? This technical session aims to help participants gain a deeper understanding of space, air changes, and where VRF technology can evolve to respond to the ever-changing demands of design.


  1. Chiller Renewal Program
  • Necessity to do the chiller renewal program;
  • Assessment and Budgeting: To determine its condition, efficiency and performance. This will help identify any issues or areas that needs improvement. This will help ensure that the project is financially feasible and that funds are available.
  • Installation: This may also involve retrofitting the existing system to improve its efficiency.
  • Maintenance: Ongoing maintenance will be required to ensure that the chiller system continues to operate efficiently and effectively. This may involve regular inspections, cleaning, and repairs as needed.


  1. Air Cooled Chiller Coil Replacement
  • Air Cooled Chiller Coil Importance Introduction;
  • Necessity to replace the air-cooled chiller coil;
  • How to implement to replace the air-cooled chiller fin coil;
  • ROI and the new performance after replacing coil.
