AC-Tec was recently engaged to upgrade and replace an outdated split ducted air conditioning system that utilized the now-phased-out R22 refrigerant. The existing unit had exceeded its expected service life and was no longer economically viable to maintain due to refrigerant scarcity, rising repair costs, and declining efficiency.

To deliver a modern, high-performance solution, AC-Tec replaced the old split ducted system with a state-of-the-art Temperzone packaged unit. This advanced system incorporates:

  • EC (Electronically Commutated) fans for precise airflow control, reduced energy consumption, and quieter operation.
  • Digital scroll compressor technology, enabling variable capacity operation for superior temperature control, enhanced part-load efficiency, and minimized on/off cycling.

In addition, AC-Tec upgraded the BMS (Building Management System) controller and control strategy to include an economy mode. This feature optimizes energy use during periods of lower demand, delivering further operational savings without compromising comfort.

The installation required modifications to the building fabric, including the removal of a section of wall and the fitting of new metal louvers to accommodate the packaged unit’s configuration and ensure proper airflow and ventilation.

A key environmental and efficiency advantage of the new system is its use of R32 refrigerant — a modern, low-GWP (Global Warming Potential) alternative to R22. The upgraded installation requires less than half the refrigerant charge of the original system, reducing both environmental impact and long-term refrigerant costs while improving overall thermodynamic performance and energy efficiency.

This project demonstrates AC-Tec’s commitment to sustainable, future-proof HVAC solutions that deliver reliable performance, significant energy savings, and compliance with evolving environmental standards.
