Carrier's Evergreen Chillers: The Chlorine-Free Way to World Class Efficiency - Without Compromises.
Introducing a significant breakthrough in chiller
technology. The Evergreen Chillers from Carrier.
For the first time ever, you don't have to choose
between high efficiency and environmental responsibility
between operating savings and long-term protection from refrigerant
phase out. With Evergreen Chillers, you can have it all.
Highest Efficiency
Using Advanced aerodynamic design principles, Carrier engineers have optimized Evergreen Chillers to deliver efficiency levels approaching .50 kW/ton at standard ARI conditions with chlorine-free HFC-134a. No other manufacturer can make that claim.
Environmentally Responsible
Evergreen Chillers use non-ozone depleting HFC-134a
refrigerant. That means you don't have to worry about costly
machine conversions as chlorine based refrigerants, such as HCFCs,
are phased out in the near future. HFC-134a refrigerant has zero
ozone-depletion potential and is classified by ASHRAE as an A1
refrigerant - the safest category possible. And with the production
of HFC-134a on the rise, you'll always have a readily available
supply of refrigerant at reasonable prices for the life of your
Evergreen Chiller.
Plus, the Evergreen Chiller's high efficiency minimizes
the amount of electricity needed. Ultimately, that means burning
less fossil fuel, a prime source of greenhouse gases.
Best Overall Value
Evergreen Chillers won't compromise your wallet either. All in all, you'll get the best efficiency and the best refrigerant at competitive prices. No compromise about it.
Engineered for Efficiency
Now, the best value in chillers delivers world-class
efficiency, chlorine free.
Carrier engineers have enhanced existing compressor
technology to achieve efficiencies once available only in chillers
using chlorine-based refrigerants. The Evergreen Chiller's centrifugal
compressor is built around an advanced impeller and tunnel diffuser,
redesigned for optimal efficiency using HFC-134a.
With the addition of Carrier's patented turbine technology,
the Evergreen Chiller achieves efficiencies approaching .50 kW/ton.
The turbine recovers energy typically wasted in the conventional
vapor compressor cycle. Connected to the motor rotor, the turbine
lightens the motor's workload and reduces the chiller's external
power requirements.
Evergreen Chillers are available with a choice of
heat exchangers sizes to optimize your chiller's efficiency for
your specific application.
Sized to Fit
To run on chlorine-free HFC-134a refrigerant, the
Evergreen uses a positive-pressure design. Positive-pressure
chillers are typically 35% smaller than negative-pressure machines
of comparable capacities. That means you'll need less mechanical
room floor space - and the Evergreen's standard take-apart construction
makes getting it there even easier.
Once your Evergreen Chiller is in place, there's
no need for expensive refrigerant containment additions. Optional
built-in isolation valves allow you to store refrigerant inside
the chiller during servicing, eliminating the need for bulky storage
tanks.
Reliable Design
The Evergreen Chiller's reliability begins with the
compressor. It's single-stage design optimizes chiller efficiency
while keeping the total number of moving parts to a minimum.
The optional high-efficiency turbine adds only a single moving
part - the turbine itself. Also, the hermetic compressor motor
is refrigerant-cooled, so it runs cooler and cleaner, and lasts
longer. Designed for superior reliability, hermetic motors eliminate
shaft seal leakage and wear, as well as the additional machine
room cooling requirements characteristic of open-drive, air-cooled
motors.
Easy to Use
User-friendly Product Integrated Control (PIC) digitally
monitors over 100 functions and displays more than 125 operating
and diagnostic conditions, allowing simple monitoring of day-to-day
operations. PIC is completely compatible with the Carrier Comfort
Network (CCN), so you can monitor and control HVAC functions from
one location using a personal computer.
