A comprehensive HVAC management system that delivers control and savings
The Save Energy Systems DLC is an intelligent HVAC management system that enables precision control of any HVAC system. It’s perfect for small to medium-size businesses (SMBs) such as health clubs, auto dealers, retailers, offices, and distribution/logistics warehouses. By installing the patented Demand-Limiting Controller, these businesses can take advantage of the same energy-saving techniques used by big corporations, and immediately reduce the largest component of their energy bill: their HVAC system.
How the DLC Works
The DLC is a patented system composed of a central controller and custom thermostats, networked together, that act as a comprehensive energy-management system. For each HVAC unit to be controlled by the DLC, the current thermostat is replaced by a special thermostat that communicates with the central controller. The central controller regularly reads the temperature from each thermostat on the DLC system network, stores it in a database, and compares it to user-defined settings.
Save Energy Systems has perfected algorithms to address the key charges that make up a typical commercial energy bill: demand, use, and peak rate.
Demand Charges, (billed by recording the highest amount of electricity used during a billing period) are controlled by preventing all the facility’s HVAC units from operating simultaneously. By doing this, the peak amount of electricity used by the HVAC units is reduced, directly reducing the demand portion of the electric bill.
Use charges, kilowatt hours used during the billing period, are initially reduced by turning HVAC fans on when the outside temperature is 55°F or less. Fans use significantly less power than compressors, so if the facility can be cooled using outside air, rather than turning on the air-conditioning compressor, power consumption is minimized and use charges are reduced. If the outside air and fan combination cannot cool the temperature zone, only then are compressors are turned on. In addition, units with multiple compressors or stages are intelligently managed so that the second stage is used much less than when managed by a standard thermostat. The DLC allows users to define holidays as unoccupied. This means that during a weekday holiday, the set temperatures will remain at the unoccupied set points, reducing unnecessary energy expenditures to heat or cool the facility when no one is there.
Peak rate charges, (higher cost electricity consumed during peak rate hours) are controlled by cooling zones to a slightly lower temperature prior to peak-rate times, and then allowing the temperature to drift up to a slightly higher set point during peak rate periods (thereby expanding the comfort zone).
The DLC system is controlled via a browser-based interface that can be viewed on a desktop/laptop, tablet or smartphone. The controller software is intuitive and easy to use, and provides the user with an at-a-glance overview of the operation, which systems are running and which are idling.
With the remote supply sensor installed, the DLC can provide the user with feedback on the operation of the HVAC unit and prevent coil freezing. If a unit is not functioning properly, the system sends an email to alert you to enable proactive, instead of reactive, actions.
