Auckland University of Technology: NorthMed

The NorthMed Clinic is a new building situated at Auckland University of Technology’s (AUT) North Shore Campus. This innovative facility which opened in July 2017, comprises of modern medical offices and teaching space for Physiotherapy, Psychotherapy, Podiatry, Oral Health, and Student Health Services.

The Challenge

The use of such small quarters for medical examination rooms meant that high refrigerant concentration levels in these spaces became a primary concern. This coupled with patient/ doctor privacy being of upmost importance meant that door grilles could not be used for this project. Therefore a traditional VRF system (without refrigerant monitoring) would not suit this particular application.

The Solution

Three Mitsubishi Electric HVRF systems were selected by the mechanical consultant to serve the smaller medical consulting rooms, along with one other standard Mitsubishi Electric VRF system to serve the common meeting and office areas.

The unique architecture of Mitsubishi Electric HVRF systems use water in the primary loop between the branch controller and indoor units, enabling the client’s refrigerant concentration concerns to be completely mitigated. This allowed total privacy in consultation rooms to be maintained, without the need to install door grilles as refrigerant piping did not run anywhere near the confined spaces.
