Heating & cooling with variable refrigerant volume system
Contractor: Conti Corporation | Sterling Heights, MI
MORE ABOUT OUR HEAT PUMPS TECHNOLOGY
This environmentally friendly mechanical system replaced traditional steel or copper piping with a polypropylene pressure piping system that features Aquatherm Fusion pipe which is a non-corroding, non-leaching, non-toxic and fully recyclable pipe free of heavy metals. This allowed for a chemically inert and emission-free installation. This piping product method was also used to deliver the geo-thermal condenser water from the geo-thermal field installed on-site to the new Daikin VRV (Variable Refrigerant Volume) condensing units. Daikin VRV is a modular, commercially applied air conditioning and heat pump system that distributes refrigerant from the outdoor unit to multiple indoor units, providing efficiency and comfort, combined with the geo-thermal field allowing both cooling and heating without the use of a gas fired unit, hot water or steam boilers typically found in a commercial building.
Over 67 VRV cassette units, 2 Energy Recovery Units and 9 VRV water cooled condensing unit were installed in the building. Combined with the solar power used to energize the mechanical equipment it is no longer dependent on natural gas or steam.
