Scroll Compressors
Reliable, efficient, trouble-free operation is the true
measure of a packaged rooftop’s value. That’s why
Johnson Controls Series 40 Packaged Rooftop Air
Conditioners use established scroll-compressor
technology to deliver dependable, economical
performance in a wide range of applications. With
the Series 40 Packaged Rooftop, you get the latest
generation of compressor enhancements added to the
scroll’s inherent strengths. The simplicity of a hermetic
scroll compressor allows the use of fewer moving parts
to minimize breakdown.
Multiple Compressor Staging
Through the use of the scroll compressor, the Series
40 has the ability to stage it’s cooling by enabling and
disabling multiple single stage compressors on multiple
circuits.
Compressor Circuiting
The Series 40 is designed so that each scroll compressor
has its own refrigeration circuit. This means more
reliable compressors, and less equipment down time.
With multiple circuits, if a compressor should ever fail
on one circuit, the other circuit/s will remain operational
to work to maintain occupied loads. The Series 40 has
4 compressor; 4 circuits.
ECOLOGICAL AND ECONOMICAL DESIGN
First packaged RTU with R410A optimized design.
Cooling and Heating
Superior operating performance provides lower
operating costs. Smaller steps of cooling capacity
provide tighter control of building environment and
occupant comfort while optimizing energy efficiency.
Indoor Air Quality (IAQ)
Outside air economizers provide energy savings in
free cooling mode, and can provide a healthier and
more comfortable building environment by introducing
fresh outside air into the building as needed. Indoor Air
Quality (IAQ) requirements for building ventilation
and comfort are controlled through the microprocessor
control panel.
High-Efficiency Motors
High-efficiency motors are available for optimum
energy efficiency. All motors used on the Series 40
packaged rooftop air conditioner meet U.S. EPACT
1992 minimum requirements.
