Case Study for Albert Einstein School: Ductless VRF Systems

The Toshiba Carrier VRF system is ideal for educational facilities thanks to its efficiency and its ability to supply varying temperatures in different spaces. The entire ductless VRF system is also controllable from one location and requires very little maintenance. So when the Albert Einstein Academy in San Diego, California, wanted to convert an abandoned nursing home into a top-notch educational facility, they turned to the power of the Toshiba Carrier VRF.

The Goal: An Efficient System with Minimal Support Requirements

When the Albert Einstein Academy set out to choose an HVAC system, they ran into several issues. First, the old abandoned nursing facility had poor support systems in place, so any complex HVAC systems were out of the question. Additionally, the new school would have several rooms with varying sizes, such as small offices, classrooms, and expansive cafeterias, so individual controls were a must. The Academy required a heating and cooling system that could effectively and efficiently heat and cool all of these spaces without requiring enormous support from the structure. Not only that, but they needed to achieve LEED Silver Certification to comply with California’s stringent Title 24 requirements.

The Solution: A Ductless VRF System

Considering the above criteria, Gene Walsh, President of Walsh Engineering, knew that the ductless VRF system by Toshiba Carrier was the perfect fit. It could provide the school with incredible temperature control for each individual space without requiring enormous support structures. Plus, it was predicted to reduce their energy costs over the previously installed VAV system by nearly 32%. The completed system—which was installed with help from Walsh Engineering and Sigler Wholesale Distributors—included:

  • A full replacement of the old VAV system with a ductless VRF system
  • A system capacity of 106 tons
  • Inverter-controlled outdoor heat recovery compressors
  • 47 indoor fan coil units (a combination of 4-way cassette, compact 4-way cassette, and concealed duct), each independently controlled via one control panel

The Results: Toshiba Carrier VRF System Earns Superior Marks

When all was said and done, everyone who was involved considered the ductless VRF system a resounding success. The 32% increase in energy efficiency translated to an impressive 12-point gain on the LEED Silver designation. When traveling from room to room, visitors felt completely comfortable, no matter what size the space was or how many people were in it. And since it is an educational facility, the staff was especially thrilled with the minimal noise the Toshiba Carrier VRF system creates.

When Albert Einstein Academy embarked on the challenge of an upgraded HVAC system, they knew it would be difficult to meet all of their requirements. With the Toshiba Carrier VRF system, not only were all of their requirements met, but the system was even more efficient and versatile than predicted.
