That makes a lot of sense, Robert. It's like the concept that the most efficeint car purchase is the one you drive till it completely disintegrates.

Hi William,

Thanks for reading the article.  You hit on a great point.  Complicate that with the UL requirement now to incorporate an SCCR (short circuit current rating) rating for HVAC control panels OEMs must implement, other issues surface: Panel design, combination component current ratings, and local jurisdiction just to mention a few.  Ah, but that's another discussion down the road.

Thanks so much for reading the article.  For the HVAC/R industry, the competition has always been fierce.  After many years of working with the OEMs out there, what they tell me is that along with upfront costs, finding that differentiator for his equipment that appeals most to the market is key.  The challenge is keeping the cost for the equipment competitive, not requiring additional commissioning or startup procedures for the installation contractor, and still providing innovation.

Hi Rob.   

Thanks for reading the article.  For the End User, I agree ROI plays an important role in the decision making process as to whether or not they should purchase new HVAC/R equipment.  Along with the ROI, upfront capital is another consideration the End User usually takes into account.  With limited budgets for HVAC/R systems replacements and upgrades, obtaining the capital to fund equipment replacement is often times a stumbling block.  However, if the End User could find a way to increase the efficiency of hs existing HVAC/R equipment and extend it's life with much less upfront capital costs, while at the same time seeing a fast ROI, the ECM has a much better chance in getting through the scrutiny of the CFO.  I know, that's a tall order, but it can be done.  Life Cycle Costing has become a standard means through which the OEM can best position his equipment on the market.  That would lead us to a different discussion.

Interesting article. But the problem with obtaining best efficiency is often created by those evile drones, the building code people who demand functions that are not only inapplicable but also cause drasitc reductions in efficiency. At least, that is what I see in this part of Michigan, my guess is that the situation is similar in a few other parts of the country. It is also apparent that the cost of mny optional functional systems is based on their desireability rather than by bom cost or the design and build effort. At least that is how it looks from the outside.

Rob, I agree, a nice article.  The market for these systems is, as the article points out, quite competitive.  Cost is key.  The idea is to get the most efficiency out of the system as they are seen to be a cost center.

Nice article, Bob. How important is cost savings to the customers in this market. I would imagine it helps OEMs make the sale if they can tell their customer there will be an ROI for the implementation.

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
