Johnson Controls is inviting all mechanical and acoustics engineers and specifiers to come and visit its new Vertical Stacked Water-Source Heat Pump Sound Room in Ajax, Ontario, home to the company’s manufacturing facility for the high-efficiency heating/cooling systems.

The condo-style sound room contains two working vertical stacked water-source heat pump (VS-WSHP) units, allowing engineers and specifiers to experience first-hand the sound performance of the high-efficiency 13 EER model and the premium-efficiency 16 EER model in a residential setting.

“Johnson Controls is the only manufacturer to offer two performance platforms for water-source heat pumps,” said Karl Washburn, principal engineer, acoustics, Building Technologies & Solutions at Johnson Controls. “Both units are engineered and manufactured to minimize noise and have undergone independent sound testing according to AHRI 260. The new Sound Room complements our recently released Sound Application Guide for the vertical stacked heat pump and gives customers the opportunity to listen to the units before purchasing them.”

The quiet operation of VS-WSHPs can be attributed to cabinets that are isolated from the wall structure to prevent vibration and noise transmission. The optional isolated chassis further reduces noise and vibration to contribute to a quieter, more comfortable environment for occupants and a more marketable facility for building owners.

Designed to replicate a room in a condominium, the 250 sq. ft. sound room demonstrates one of several applications for VS-WSHPs that also include high-rise apartments, dormitories, renovated office space, assisted living communities and other multi-story buildings with repeating floor patterns, as well as the replacement market.

“High-rise construction, whether two stories or 20 stories, presents unique HVAC challenges,” said Dan Tyson, product manager, Indoor Packaged Equipment (IPE), Johnson Controls. “The challenge is to maximize floor space for occupants and still create efficiencies during and after construction. Our vertical stacked heat pumps feature design and construction details that provide the flexibility you need—things like a compact footprint, the flexibility and comfort of a four-pipe fan coil system at the cost of a two-pipe system, optional individual tenant metering and easy service access.”

Johnson Controls VS-WSHPs also deliver total system efficiency with energy recovery for heating, cooling, humidifying and dehumidifying. For additional operating efficiency, the units offer fully integrated digital controls featuring BACnet®, MS/TP and LON® protocols and seamless BAS integration. And because water transfers heat more efficiently, the water-source heat pumps are the ideal solution for water-loop and geothermal applications, reducing energy costs up to 50%, when compared to conventional cooling and heating systems. Energy conservation can also be attributed to a design that places less load on the cooling tower and boiler.
