How HVAC Optimization Controls Work (continued)

IntelliCon-CHW determines the “heat load” by using an easily installed strap-on temperature sensor that monitors the boiler’s out-flow water temperature and the rate that this temperature is changing. Using our patented technology, IntelliCon-CHW increases “system efficiency” thus the heating system uses less fuel to generate the same amount of heat. This is done by dynamically changing the aquastat’s effective dead-band based upon the measured “heating load.” This causes the average water temperature to be varied (depending upon the measured load), and is accomplished by extending the burner’s “off-time.”

Extending the “off-time” results in longer burns that are more efficient and a reduction in burner on/off cycling. Just as computer control has increased the gas mileage of automobiles: IntelliCon-CHW improves the fuel utilization of heating systems, by supplementing the antiquated on/off control action of the aquastat with the analysis and control capabilities of a computer.

Facility engineers will appreciate the illuminated LCD readout, which displays useful information relative to the unit’s status, system temperatures, and burner run-time, all of which are useful for system maintenance. IntelliCon-CHW typically reduces fuel consumption 10% to 20% and decreases burner cycling 30% or more.

Installation, by a qualified service technician, takes about 60 - 90 minutes and does not require any programming or adjustments. The IntelliCon-CHW small 7 1/2”H x 9 1/2”W x 4”D size allows it to be installed almost anywhere. After installation, IntelliCon-CHW does not require any maintenance.

Types of Facilities Recommended For Intellidyne

Buildings with boiler plants that are hot water or steam and are used primarily for heating and domestic hot water production.  Small modular boiler plants are generally not a good fit for the Intellidyne Boiler Controller.  Based upon prior experience, process heating loads should be approached with caution due to its constant load nature.

Energy Savings Methodology and Results

The savings approach is based upon reducing the amount of boiler on time without reducing the heating response time or system capacity in response to warmer periods of the year, and when demand for heating is low or non existent. Energy savings methodology is primarily based upon the reduced quantity of pre-purge and post-purge air that is part of the normal firing cycle.  The second contributor to savings is due to the higher overall temperature differential between the water side and the fire side of the boiler system as well as the longer combustion cycle.
