Providing effective and reliable energy efficiency solutions for HVAC-R customers around the globe.

2. Smartcool… …Green technology, green rewards
Background
In the mid-80’s Australian refrigeration engineer, Tony Murphy observed that strategically unloading a system could maintain temperature and significantly reduce energy consumption.
Tony invented the ESM, still a state of the art technology used in rack and chill water systems
In 2009, Smartcool International introduced the ECO3 as a consumarized version of ESM for DX systems
Smartcool solutions adopted widely across a range of industries for over years, more than 50,000 installations worldwide
Smartcool Energy Saving Module (ESM)
Smartcool ECO3

3. Thermodynamic Principle
Compressor optimization dynamically adjusts the length of each operating cycle in order to have the compressor run more often at a higher suction pressure where it is most energy efficient.
Smartcool achieves greater energy efficiency for the compressor without allowing the compressor to short cycle and without affecting the controlled space temperature.

5. Thermodynamic Principles Explained
This is a very busy box!
Upon Compressor Start:
Suction Pressure High, Head Pressure Low, Condenser Cold
These Conditions promote high mass flow rate = high capacity
Conditions reverse as capacity (suction) declines to rated value
Remember: COP is a function of Suction Pressure (Mollier Chart)
The ECO3 internally models system performance looking over past cycles and predicts next cycle minimum run time, inherently maximizing suction pressure
By constantly and dynamically adjusting the run cycles, the compressor delivers the highest possible COP - -for that specific system and that specific load pattern
Essentially, the ECO3 is modulating excess capacity for higher efficiency
All Systems have excess capacity, that is why they cycle
During times with no excess capacity, no savings

6. Design Features of the ECO3
During the ECO3 Design Phase, certain features were essential:
On Screen Display to show actual savings, load factor and diagnostic data
One and Two Stage Capability
Flexibility of installation, anywhere between thermostat and compressor
Only needs to see a thermostat call
Flexibility of application, AC, Refrigeration, Heat Pump
Voltage switching from 24 to 250 VAC, up to 5 amps
Robust Design
Physically and Electrically hardened
Simple operation – one button
Simple Installation, 2 dip switches
Anti-short cycling logic
Software upgradeable
Inexpensive

7. Operational Features of the ECO3
Compressor Optimization is about more than mathematics
Customers & Installers have operational requirements to address
Smartcool’s 30 years of practical Lessons Learned is incorporated into every product line:
Special logic to accommodate the many configurations of two stage systems
Special Logic to promote fast morning and defrost temperature recovery
Special Logic to prevent short cycling
Internal Self-test logic
Fail safe product design – reverts to normal thermostat
Special logic for installation and onsite testing
Internal health monitor circuit
Internal signal isolation
Annunciators that communicate operation mode
User accessible data registers to display performance and diagnostics

8. What it means for you… For Customers For Distributors
Typical savings 15-40% depends primarily on Load Factor
If the power bill is $400 per month & 60% is AC
The ECO3 may save 25%: So 60% x 25%= 15% Monthly Savings = $720 per year
At 10% annual utility Increase= $11,500 over 10 years!
For Distributors
Kitchen Table close rates 50-75%
MSRP $ (simplex)
Profitable on both unit pricing and installation
Reliability in the 98-99% range
Does not affect warranty (any more than a Honeywell Tstat)

9. Testimonials Some comments we’ve heard
“… lowest electric bill in 11 years.”
“Set it and forget it. My electric bill shows it working.”
“Sweet revenge for my family’s thermostat wars.”
“It’s already installed?”
“We had another great month, what discount can I get for units.”
“ We save $200 a month on our [commercial] pool.”
“Jesus Bruce, quit calling me.”
