Water Source Heat Pumps

Carrier Aquazone™ Water Source Heat Pumps (WSHPs)

are a great solution for year-round multi-zone heating and cooling. Our wide range of WSHP models deliver efficient, reliable temperature and humidity control for a variety of
applications. Utilizing the earth's natural resources along with our
engineered operating flexibility, Aquazone heat pumps deliver Energy Efficiency Ratios (EER) up to 35. Carrier WSHPs let you put heating and cooling capacity exactly where and when you need it. Aquazone units are available in numerous sizes and configurations with several standard and factory-installed options allowing you to configure systems for today as well as for expansion in the future.

HOW IT WORKS

WSHP systems are designed to take advantage of the fact that the earth's resources (ground or water) remain at a relatively constant temperature at a certain depth. Instead of using a conventional heat source, the ground water can be used as the heat sink for absorption or rejection of heat. Geothermal Earth Loops come in several different configurations depending on space availability and soil properties. Geothermal heat pumps can work with closed or open loops. Open loops work best with well, river, or lake water applications. Closed loops can be installed in vertical or horizontal ground configurations, or submerged
in a pond or lake.

EFFICIENCY

Carrier Aquazone heat pumps are designed to reduce
utility costs, especially under part-load conditions and over
a lifetime of operation. HFC Puron® refrigerant (R-410A) two-stage models offer Energy Efficiency Ratios (EERs) up to 20.8 in boiler/tower applications. High-efficient heat pumps in a geothermal application, where they simply move heat within the earth that already exists can achieve EERs up to 35 along with exceptional heating
performance with heating coefficient of performance ratings as high as 5.

RELIABILITY

Built with heavy-gage, galvanized steel sheet metal cabinets and featuring a corrosion-resistant, powder-painted finish, Carrier Aquazone WSHPs are durable and long lasting. All water and air coils, plus drain pans are available with coating options to protect against corrosion and airborne chemicals, plus state-of-the-art compressor technology yields the highest efficiency and reliability.

CONTROLS

Carrier's WSHP Open Controller features plug and play connectivity to the Carrier i-Vu® Open Control System. The Carrier i-Vu Open Control system combines state-of-the- art Carrier equipment, plug-and-play controllers and the powerful, web-based i-Vu user interface to form a cohesive, intuitive, and fully integrated building automation system(BAS). WSHP Open also includes advanced independent fan speed and compressor operation and proactive diagnostics to ensure reliable and efficient operation.
For added flexibility, the WSHP Open controller is capable of stand-alone operation. Or, it can be integrated with any BAS utilizing the BACnet®, Modbus®, Johnson Controls N2
or LonWorks® protocols.

QUIET

Advanced engineering has made Carrier Aquazone heat pumps among the quietest on the market. Noise-reduction features such as cabinets with dual density acoustical insulation,low-speed blowers and ECM or constant torque motors plus fan motor insulation are standard on Aquazone units. The isolated compressor railing system minimizes vibration transmission, and most units feature isolated compressors for additional sound protection.

INDOOR AIR QUALITY

While efficiency and environmental demands are shaping the Water Source Heat Pump industry, indoor air quality is also an important part of the equation. Carrier offers a full variety of outdoor air options that can introduce conditioned ventilation air into a WSHP system. In conjunction with our outdoor air options, utilizing Carrier's WSHP Open controller and CO2 monitoring allows Carrier's heat pump systems to deliver the right amount of
conditioned ventilation air at the right time while lowering the overall system size and usage costs.
