As indicated in Step IV, Temperature Control System Revisions, we are more and more frequently determining that replacement of the broken, dirty, antiquated pneumatic temperature controls systems, is in our client's best long-term interest. However, this is a recent phenomenon for Climate Makers. We never hopped on the energy management system (EMS) bandwagon. We felt that many of the strategies of the early time clock like systems were ill conceived. Our experience of fixing what was broken, cleaning what was dirty, working with the in-house maintenance personnel and eliminating simultaneous cooling and heating was proving to save more, cost less and provide greater comfort improvement. We'll admit that our work didn't have much prestige, but our clients came to understand its effectiveness.
The main problem is that: ventilation rates change; sequences of operation for greater comfort improvement change; classroom and office functions change; and so on. Each time this happens, the pneumatic temperature control panel has to be reworked. This can often be done by simply re-utilizing the existing controls. But as you can imagine, just by looking at the pneumatic temperature control panel below, it takes considerable skill to do so.
Today, the features, advantages, benefits and low cost of direct digital control (DDC) cannot be ignored. Climate Makers is a "System Integrator" for Teletrol Building Automation Systems, a world-wide leader in providing state of the art building automation systems. Now, whenever system requirements change, all the work is done from a keyboard. And with the help of the internet, can be anywhere in the world! You can visit Teletrol's website at: www.teletrol.com.
The most unique feature of Climate Makers' building automation department is that we provide these services with the same personnel that have been solving indoor air quality, comfort and energy conservation problems, for more than 20 years - PIPEFITTERS! To us, DDC is simply the next generation temperature control system receiver/controller. It's just no longer a pneumatic device. The advantage is that our DDC Department personnel know what the mechanical equipment should and should not do. As an example, we are regularly given the task of fixing other building automation systems that leave the air conditioning compressors run, even though the respective air handling systems have been shut down for hours.
The other major new technology hardware we encourage you to investigate is new boiler burners or even new boilers. Climate Makers has always made every effort to provide quality products at fair prices, instead of always trying to provide the least expensive solution. Today, we encourage steam boiler systems to be converted to hot water boiler systems. This allows our clients the ability to take advantage of the latest in condensing boiler technology, with boilers that operate as high as 98% efficiency. You can visit one such manufacturer's website at: www. aerco.com.
Again, space limits us from describing in detail, all the features, advantage and benefits, but suffice it to say that high turndown ratio burners are superior. Weishaupt has such high turndown ratios, that once a building needs as little as 10% of the design heating capacity, the burner will often run continuously, all day long. That means greater efficiency. And fewer on and off cycles, means less wear and tear on all moving parts. To date, we have had no problems getting every gas utility company to provide rebates for the installation of Weishaupt burners!
