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 City Multi Hybrid VRF (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 allows total privacy in consultation rooms without the need to install door grilles as there is no refrigerant in confined spaces. As a result, there is no need for expensive leak detection systems to be installed.
