Introducing the Air Energy Controller
The AIR ENERGY CONTROLLER™ automatically learns the characteristics of new filters, even if the new filters are a different type.
The AIR ENERGY CONTROLLER™ works with variable flow.
In many applications energy is not yet the main factor; air quality is the main factor. In other applications the reverse is true. Energy costs will continue to go up. Air quality requirements will continue to get tighter. Filter technology will get better. The AIR ENERGY CONTROLLER™ is designed to accommodate these changing conditions.
The AIR ENERGY CONTROLLER™ uses an advanced ARM processor and sensor electronics to measure the pressure drop across the filters and average velocity through the filters. Additional information is supplied by the user; filter area, cost per kilowatt hour, and filter costs. Using standard energy equations, the processor calculates the energy being used and the average TOTAL-COST-PER-DAY by keeping track of time since the filters were replaced.
When new filters are installed, the AIR ENERGY CONTROLLER™ automatically learns the characteristics of the new filters and restarts the evaluations.
 Energy & Condition:
The ENERGY used to force air through filters is directly related to the CONDITION of the filters.
We define the CONDITION as the ratio of Dirty-ΔP to Clean-ΔP at the same velocity. For example, if the CONDITION = 2, the filter ΔP has doubled since it was new (measured with the same velocity).
ENERGY = Q x ΔP x t / n / 1000
The same ratio applies to the rate at which ENERGY is being used.
DIRTY FILTER ENERGY rate = CONDITION x CLEAN FILTER ENERY rate.
 Energy Costs vs. Dirty Filter Costs:
The average COST PER DAY for filters is the cost of the filters divided by the number of days used. The average COST PER DAY decreases with time.
The extra energy cost starts at zero with new filters and rises steadily as the filters become dirty. The dirtier the filters, the more energy it takes to force air through the filters.
The average TOTAL COST PER DAY is the sum of the average FILTER COST PER DAY and the average extra ENERGY COST PER DAY.
Economically, the best time to change the filters is when the average TOTAL COST PER DAY is minimum.
Optional Setups:
REMOTE or STAND-ALONE: The AIR ENERGY CONTROLLER™ can be used as a stand-alone device or connected to a single or multi-drop RS485 network. Multiple units can be attached to the same RS485 network and accessed separately.
DATA and PARAMETER ACCESS: All measurements and user supplied parameters can be accessed from the device or remotely.
UNIQUE SETUP: Since each installation is unique, the user defines the control parameters. One user may be more interested in air quality than energy usage or lowest cost. Each user has control of the setup.
REPLACEMENT POINT DETERMINATION: The user can decide to replace the filters based on any combination of the following: total calendar time, total filter usage time, filter CONDITION, energy rate, minimum cost rate. For example, a user may decide to replace the filters if (1) total time is greater than 6 months, or(2) the filter CONDITION is greater than 3, or (3) the minimum cost rate has occurred.
SETUP CHANGES: The user can always re-adjust parameters to meet changing demands.
