Introduction

Performance, Value and Stainability in a Labor-Saving Package.

The Vertical Stacked Water Source Heat Pumps (VPCS) from Johnson Controls offer

the ultimate in multi-story HVAC design flexibility. The VPCS Series is a compact, con-

cealed system, capable of providing total heating and cooling functions for a single zone

or multiple rooms. These units offer the flexibility of a four-pipe fan coil system at the

cost of a two-pipe system, with the added flexibility of individual tenant metering. VPCS

Series units are ideally suited for the total heating and cooling needs of any two-plus story

building with a consistent floor plan.

• Hospitals / Nursing homes

• Dormitories

• Renovatedofcespace

The space saving VPCS unit is a two-part system featuring a self-supporting, pre-piped

cabinet, and a removable heat pump chassis. The cabinet, complete with supply/return/

drain risers, is installed during the intermediate phase of building construction. The cabi-

net is framed-in, and covered with drywall, as part of the interior wall structure. The

finished equipment installation is hidden from view, blending with the decor of the room.

Access to the mechanical components of the unit can be made entirely through the front/

return air panel.

The provision for as many as three cabinet supply air outlets allows for maximum design

flexibility and cost savings. One strategically located unit can serve up to three sepa-

rate rooms without the need for ductwork. The ease of removal and replacement of the

heat pump chassis offers enhanced serviceability. A chassis that requires service may be

quickly removed, replaced with a back-up chassis, and serviced at a more convenient

time or place.

All units are tested and certified by AHRI / ISO 13256-1 and ETL for United States and

Canada. Johnson Controls stacked heat pump design exceeds ASHRAE 90.1 require-

ments at all rating conditions, making the VPCS series an excellent choice for water-loop

and geothermal applications.
