EVALUATING BUILDING AUTOMATION SYSTEMS

Southern California Sigler’s HVAC News

Pre-Engineered Control Strategies Ensure Reliability Pre-engineered control strategies include documented operation sequences for available functions and can save time typically spent writing detailed specifications for controls. The factory-documented functions also provide owners with information required for service, expanding service options. Pre-engineered control programs minimize the need for field programming and facilitate the start-up and commissioning process. Lastly, some of the most valuable built-in system strategies can promote energy savings.

When building automation systems were first introduced, the advantages of centralized control of the heating, ventilation and air-conditioning (HVAC) systems were widely recognized. As the building automation system evolved to include management of lighting and other building functions through direct digital controls, the building automation system became a tool for operation and data collection designed to enhance occupant comfort and save energy. Today, while most building automation systems provide complete building control and offer local and remote access for monitoring and regulation of equipment, the best of these systems include flexible, factory-installed controllers with built-in features like pre-engineered control algorithms and pre-loaded graphics and automated reports. These features can simplify the design and commissioning of the control system, minimize installation and service costs, and offer engineers and building owners a reliable, energy efficient, and easy-to-operate system.

Examples of available pre-engineered control strategies are described below:

Demand Limiting– Utilizing less power when energy rates are high.

Demand Controlled Ventilation- Eliminating the energy waste caused by over-ventilation and over-treatment of outdoor air.

Set Point Control– Limiting the amount of adjustment that occupants can make to the configured zone set points.

Free Cooling and Integrated Economizer– Utilizing outside air instead of mechanical heating and cooling contribute to energy savings.

Static Pressure Reset– Optimizing fan speeds during partial load conditions where full load design static pressure is no longer needed.

Air-Side and Water-Side Linkage Routines– Operating air source equipment, pumps, cooling towers, and coilers in conjunction with building demands.

Patterson EnviroFlo™ end suction HVAC pumps offer a high-efficiency design that minimizes energy consumption, and their back pullout configuration provides easy access and simplifies maintenance. But in addition to this they offer a distinct advantage over the typical industry-standard end suction design ...

THE PATTERSON END SUCTION PUMP ADVANTAGE

Southern California Sigler’s HVAC News

The typical industry end suction pump has a base constructed of welded or bolted cross members which must be grouted by the installer to ensure structural rigidity and mitigate flexing due to the torque of the motor starting and stopping. This grouting process involves cleaning all the areas of the baseplate that will come into contact with the grout, building a dam around the foundation, thoroughly wetting the foundation that will come into contact with the grout, pouring grout through the grout hole into the baseplate up to the level of the dam, removing air bubbles form the grout, allowing the grout to set, filling the remainder of the baseplate with grout, and allowing the grout to set for at least 48 hours. Whew!

Now contrast this with the Patterson end suction pump which is constructed using a channel steel base...because it is constructed a solid formed channel, it will not flex whatsoever and provides complete structural rigidity straight out of the box without the requirement to grout the base! The savings in time, labor and expense are significant.

Typical “Brand X” end suction

Applying more than a century of engineering expertise in hydronic pumping technology to HVAC applications, Enviroflo™ pumps offer the rugged, reliable service and engineering refinements you expect from Patterson along with sustainable, energy-efficient performance that addresses Green strategies and are proudly represented by Sigler Commercial Sales.

Great news! A new weather application is now available for the Carrier i-Vu System. This add-on displays current weather conditions and forecasts from within the i-Vu system so that it is not necessary to navigate to an external website to get live weather data. The weather data that is retrieved can be displayed on a graphic page as shown, or read from a control program for use in control logic. Sample control strategies would include the adjustment of setpoints based on current outdoor air temperature and humidity conditions, or pre-conditioning spaces based on predicted weather conditions. These strategies can help owners to achieve energy savings while also providing occupant comfort. The new Weather Add-on can retrieve weather information from the US National Oceanic & Atmospheric Administration National Weather Service, Environment Canada, and AccuWeather.com™.
