THANK YOU! * Year-Round Individual Control Each zone heat pump provides individual temperature control. This allows each occupant to control heating or cooling regardless of season, during or after hours, regardless of what other zones are doing. Zones served by single heat pumps can be as small as 20 square meters or as large as hundreds of square meters. Energy Savings Water-Source Heat Pumps provide zone heating and cooling at the highest rated levels of efficiency. The water loop inherently recovers much of the energy needed for heating the building, minimizing boiler use. Water-loop heat pump systems operate efficiently under partial occupancy and at part-load conditions. They also eliminate the double energy waste of zone reheat (cooling with subsequent reheating), which is common in many HVAC systems. This all translates into reduced energy consumption and lower operating costs. Tenant Metering The majority of the system operating cost occurs at the zone heat pumps, which can be metered at the tenant level. Thus, tenants pay for only what they use. Quiet Operation In many central plant HVAC systems, the noise and vibration from reciprocating or high-speed centrifugal chillers and high-speed, high-static centrifugal fans is difficult to mitigate. Although they are located close to or within the occupied space, contemporary water-source heat pumps are capable of operating as quietly as many fan coil systems. Sound power levels in the latest models have been reduced through the use of new compressor technology, variable speed fan motors, acoustical isolation techniques, and optimization of design through extensive sound testing. Quiet operation has become a fundamental requirement for many tenants. Low Initial Costs Water-source heat pumps are factory assembled and tested, usually incorporating all zone-level controls and hydronic accessories, reducing expensive on-site labor. They utilize basic low-pressure duct systems or in some configuratio
