Smartcool - Model ESM - Advanced Energy Efficiency Retrofit Product
Smartcool's ESM is an advanced energy efficiency retrofit product that can save up to 40% kWh energy on compressor operation in even the most complex air conditioning and refrigeration systems (HVAC-R). Energy savings by the ESM are achieved using the compressor optimization strategy most appropriate for the exisiting equipment. As a modular product, the ESM is customized for each installation, giving it complete compatibility with a wide range of equipment and controls.

Technology
The ECO3 and ESM are Smartcool’s unique retrofit technologies, that use intelligent compressor optimization, which can reduce the energy consumption of compressors in air conditioning, refrigeration and heat pump systems by up to 40%.
Air conditioning, refrigeration and heat pump (HVAC-R) units waste a lot of energy through natural inefficiency. Their compressors consume about 70% of the total energy used by the system. The average building has about 35% of its total energy used up by these systems- and many businesses see much more of their energy bill coming from their cooling systems.
The ECO3 or ESM is installed between the thermostat or primary controller and the compressor in any HVAC-R system. Here's how it works:'
Conventional Cooling- Temperature in a controlled space will rise until it hits the maximum temperature allowed by the thermostat. The thermostat will then ask the compressor to run until the minimum temperature is achieved.
- his system is operating within a control band. As the top of the band when the compressor begins to run, conditions are at their most efficient.
- As the compressor continues to provide cooling and approaches the bottom of the control band, it is using twice as much energy to achieve each degree of cooling as it was when it started at the top of the band.
Smartcool solves this natural inefficiency with compressor optimization tailored to suit the existing controls and equipment.
Smartcool Cycle Optimization- Smartcool's ECO3 and ESM are installed between the compressor and the thermostat or controller. From there, they actively monitor and analyze the conditions of the system.
- The ECO3 and ESM use the information they gather to dynamically adjust the length of each cooling cycle in order to help the compressor operate more often under its most energy efficient conditions.
- The ECO3 or ESM will intercept the signal from the controller and calculate when the compressor should start and how long it should run for maximum energy savings while still achieving temperature requirements.
martcool's technology will not allow the compressor to short cycle and keeps it operating within manufacturer recommended conditions.
Some systems, like chillers (also called chilled line systems), may require a more advanced control methodology. For these systems, Smartcool provides custom load management strategies to save energy.
Advanced Load Modulation- Smartcool's ESM can be installed within existing control methodologies to modulate load for periods of time during the cooling cycle
- The ESM continues to actively monitor the system operating profile, but will not turn the compressor on or off.
- Instead, the ESM is able to intelligently vary the compressor capacity through the controller, shedding load when it is not needed to achieve cooling requirements.
Smartcool or a local distributor visits your building or home to gather information on what cooling equipment you have and how much energy it uses. This energy audit is free and you have no obligation to go any further.
2. Energy Savings ProposalUsing our findings from the Energy Review, we give you a proposal that tells you how much energy and money we can save you, and how much a Smartcool project will cost. An average Smartcool project would save you 15% kWh usage from your cooling compressors and give you a return on investment in approximately 12 to 36 months.
3. InstallationIf you are happy with our Energy Savings Proposal, we schedule the installation and get started on saving you energy. All work is done by Smartcool approved contractors or employees according to all applicable codes, regulations, and facility-specific safety and operational requirements. All Smartcool contractors have appropriate worker's compensation and general liability insurance coverage.
Safe SolutionsSmartcool's energy efficiency solutions have been adopted by some of the world's most prominent companies across a range of industries, and have undergone rigorous independent third party testing.
Risk free solutions:- Compatible with all existing equipment and controls
