Application Considerations
Advantages of Geothermal
The advantages of a geothermal heat pump system can literally decrease heating and cooling
operating costs by 30%-40%.The units are durable, and typically last longer than conventional
systems.They are protected from harsh outdoor weather conditions, because the unit is installed
indoors and the loop underground. According to ASHRAE, the estimated service life for a
commercial water-to-air heat pump is 19 years.
Geothermal heat pumps have fewer mechanical components, making them more reliable and less
prone to failure.
Geothermal heat pumps work toward the preservation of the environment by reducing the
environmental impacts of electric power generation.
Flexibility
The vertical, high-rise water-source heat pump system is versatile for installation in boiler/cooling
tower applications, as well as ground-source (geothermal) applications.The system typically
employs a central pumping design.The central pumping design involves a single pump design,
usually located within a basement or mechanical room to fulfill pumping requirements for the
entire building system. An auxiliary pump is typically applied to lessen the likelihood of system
downtime if the main pump malfunctions.
Installation Tips
When installing a high-rise water-source heat pump, there are specific installation requirements
that should be taken into consideration.These include:
• Noise control
• Riser location
• Furring-in the unit
Sound Attenuation
The high-rise heat pump is better suited for acoustically sensitive water-source heat pump
applications than other water-source products. Compressor and water noise are attenuated by the
filter panel, sheet rock and the acoustically lined door. Air noise is silenced through the extended
and insulated duct portion at the top of the vertical cabinet.
Furring-In the Unit
The vertical high-rise water-source heat
pump is designed to be a furred-in
application. Dry-wall (sheetrock) is attached
to furring studs (not unit cabinet) until the
entire cabinet, except the front access panel,
is enclosed. Access to the unit is made
entirely through the front panel which spans
approximately one-half of the unit height.
The dry-wall enclosure allows the unit to
blend in with the decor of the room. If
renovations are needed, the drywall portion
of the unit can simply be re-papered or
repainted with the remainder of the room.
With careful design, the high-riseWSHP can
be incorporated into a room design, while
occupying minimum floor space.
