Temperature, humidity won’t sink this U-boat

View the full story, including all images and figures, in our monthly digital edition More than a half-century has passed since the German U-505 submarine was captured during World War II, but the curators at the Museum of Science and Industry in Chicago strive to keep the sub looking in fighting shape. Since the U-boat's capture in 1944, it has survived a near sinking, a treacherous tow from the Atlantic to the Great Lakes, and 50 years of bitter Chicago weather in its post as an outdoor exhibit at the museum. In 1997, the museum began a restoration project designed to preserve the U-505 and move it indoors to a climate-controlled environment. Presently, the submarine resides on a specially constructed 75 x 42 ft underground exhibit space at the Museum of Science and Industry.

PEX tubing

Alumicor PEX-Al-PEX tubing from Zurn Industries offers all the benefits of cross-linked polyethylene tubing, plus it holds its shape when it is bent. The tubing bends easily but then stays in place thanks to a layer of aluminum that is sandwiched between two layers of PEX. This layer not only gives PEX tubing an easy-to-handle, malleable characteristic, it also improves heat transfer and acts as an oxygen barrier, which helps protect the boiler and all other non-ferrous system components from corrosion.

The survey, the fifth installment in a series of SEER 13 market surveys that St. Louis-based Emerson Climate Technologies has conducted in 2005 and 2006, questioned HVAC contractors and distributors across the industry about their awareness, planning, actions and concerns regarding the SEER 13 regulations. The purpose of the surveys is to help provide an accurate picture of the market’s transition, which is paramount to maintaining uninterrupted product delivery and high quality levels. The most recent survey shows that 77% of SEER 10 inventory has been used up and indicates a prediction that 97% of SEER 10 inventory will be used up by the end of 2006. “Some contractors communicated through the survey that they had stocked up on 10 SEER inventory in anticipation of the 13 SEER transition,” said Karl Zellmer, vice president of air conditioning sales, Emerson Climate Technologies.

A study of asthmatic children reveals that an ultraviolet air disinfection system in home ventilation ducts can dramatically reduce asthma attacks and allergic reactions to indoor pollutants. The first study of its kind, published in the May issue of the Journal of Asthma, found that participants significantly improved their breathing capacity, reduced medication use two-fold, increased the number of days without symptoms four-fold, and experienced reduced symptom severity when an asthma attack did occur. Ten million people in the U.S. suffer from allergic asthma, and poor indoor air quality contributes to the problem. The study, funded by an NIH Small Business Innovative Research grant, offers hope for an inexpensive and safe way to control allergic asthma.

A/E Confidential: Protecting Trade Secrets

It seems as though everywhere you turn, you run into someone requesting a “confidentiality agreement.” A recent experience comes to mind. I represented a landlord whose prospective tenant was in the commercial real estate brokerage business. The tenant demanded a general confidentiality agreement, presumably to prevent the landlord from snooping around its offices and learning its business secrets. The tenant was eventually persuaded that it was neither appropriate nor necessary; and, indeed, I believe any tenant ought to reconsider leasing if it truly worries about a landlord grabbing its perceived business secrets. For purposes of the current discussion, this story illustrates two things: • The increasing awareness of the value of proprietary business information and intellectual property. • A general lack of understanding among lay business people of what can and should be protected under the law and the mechanics of obtaining such protection. In approaching the topic of confidentiality, one must consider two often-intertwined concepts: confidentiality agreements and trade secrets.

NASA-Funded Outreach Program Helps HVAC Installer with a Dilemma

Thanks to assistance from the NASA-funded Space Alliance Technology Outreach Program (SATOP), a Fort Worth, Texas HVAC installer has created a safe and efficient means to solve the normally tedious and difficult task of setting copper refrigerant lines when installing AC systems. Vess Polk, president of A-Redemption, a product development company, has devised a line guide that would enable one person, instead of the usual two, to install the copper refrigerant line while at the same time reducing the potential for damage to the lines. SATOP, administered through the Bay Area Houston Economic Partnership, provides free engineering assistance to small businesses with technical challenges through the expertise of the program's 50 alliance partners, made up of aerospace companies, universities and NASA field centers involved in the U.S. Space Program. "I discovered in my 21 years of installing air conditioning systems that it was impossible to position the lines by yourself in tightly constrained attic space.Plus, nails and other impediments would frequently damage the lines," explained Polk. Polk's initial idea of a line guide sounded feasible, although early prototypes created friction. "I had resistance when pulling the line set through my invention; obviously, this had to be resolved in order for the guide to work," he said. Fortunately, Polk learned about SATOP through the Fort Worth Chamber of Commerce's Small Business Services Department.After Polk filled out a Request for Technical Assistance (RTA) with SATOP he was matched with John Dillon, a mechanical engineer with Alliance Partner AJT & Associates in Cape Canaveral, Fla. "Vess Polk's design had a tendency to compress the insulation against the line, which could affect the insulation integrity and also bend or kink the pipe, thereby impeding the delivery of the coolant," said Dillon."I began working on a design that would reduce drag in the line guide with any size of piping and insulation." Dillon suggested a two-piece opening in the metal guide that would allow the user to adjust the opening to whatever width is needed and still keep the wall stud structurally firm.

Use of Sensors in HVAC Definitely on the Rise

Opportunities for sensors in HVAC applications in North America are on the rise, driven primarily by the rapid growth of non-residential construction and increasing concerns about indoor air quality. New analysis from Frost & Sullivan , “North American Sensor Opportunities in HVAC Applications,” reveals that the total sensor market for HVAC applications generated revenue of $302.2 million in 2004 and is expected to reach $692.8 million in 2011. Researchers suggest the statistics suggest a continuation of the trend toward sophisticated building automation, with engineers and facility managers looking to manage and optimize the control systems using feedback from sensors. Conventional mechanical systems are increasingly being replaced by electronic controls that require intelligent sensors for better accuracy and system performance. “The impact of the new commercial construction growth rates on the overall building automation market revenue is expected to drive the sensor market,” notes Frost & Sullivan Industry Research Analyst Dr. Rajender Thusu.

Protecting Ductwork and Cold Water Piping From Mold

There are more than 100,000 known species of mold.Mold spores (seeds) are everywhere, indoors and outdoors, in our building materials, on our clothes, and in the air we breathe.We can’t avoid them, but we can minimize their potential for growth in our buildings.And we should .Mold is a common allergen; it exacerbates asthma, and can cause infectious disease in some people.It can also have far reaching legal consequences for owners and others in the construction industry. The Nature of Mold Mold requires 3 things to grow:(1) food (2) temperatures between 40 to 100 This involves much more than wiping up the occasional leak.It requires vigilant control of moisture entry into the building and prevention of condensation throughout our ductwork and cold water piping. Moisture Happens Mold doesn’t require standing water to grow.High humidity is moisture enough for mold spores to germinate.Ideally, buildings should maintain relative humidity of 60% or lower—not only for comfort, but to prevent mold growth.Unfortunately, areas of high humidity are bound to occur in some areas of an HVAC system. High relative humidity levels in air handling units occur any time outdoor air dew points are above the coiling coil discharge temperature (typically 61°F)Air discharged from the cooling coils under these conditions usually has a relative humidity level of 90% or higher.Provided food is present, this is all it takes for mold to grow. Condensation is another problem, occurring whenever air comes in contact with surfaces that are cooler than the dew point of the surrounding air.This makes cold water piping and cold ductwork prime areas for unwanted moisture.This moisture can condense into liquid at the wrong place and the wrong time, wetting building components such as ceiling tiles, drywall and carpeting, and setting the stage for mold growth. Insulation:The Key to Preventing Unwanted Moisture Insulation is the best way to avoid condensation in ductwork and piping systems.However, if improperly installed or damaged, some types of insulation can provide a cozy breeding ground for mold. Closed-cell, elastomeric foam is the first and only type of insulation to provide thermal efficiency along with the necessary prevention of condensation and water vapor transmission on cold water and air handling systems. There have been numerous studies that support the case for closed-cell, elastomeric foam over fiber glass and cellulous-based products when it comes to mold prevention.The reason for this is twofold. Fiberglass structure provides a wicking opportunity for moisture; therefore moisture can quickly travel, expanding the area for potential mold growth. Fiberglass tends to trap and collect dirt.In fact, the air pockets that make fibrous type materials an effective insulator also makes them prone to trap and retain dirt. According to the April 2004 ASHRAE Journal, “Porous materials such as internal fibrous glass liner have been identified as a major source of fungal contamination.” The same article references a study in which fungal growth on fiberglass linings was found in 92% of 150 office buildings in Minnesota with IAQ problems. This particular study found that the average microbial levels in fibrous glass insulation are hundreds — and in some cases thousands — of times higher than the microbial levels found on closed cell foam insulation under the very same environmental conditions.1 Based on these facts, many experts recommend replacing fibrous glass liners with materials that are less likely to encourage fungal growth (i.e. closed-cell foam insulation) in areas where humidity is likely to exceed 70%. An increasing number of schools, universities and other facilities seeking better IAQ have made the same decision, replacing existing insulation with elastomeric foam, not only for its mold-resistant properties, but its fiber-free, dust-free, and non-particulating construction. Why Closed Cell Foam Is the Better Choice for Mold Prevention Unlike fiber-based products, which have been found to hold moisture for up to 16 days2, closed-cell elastomeric foam won’t absorb moisture.Its smooth surface also inhibits the accumulation of dirt which serves as a food source for mold. Properly installed and maintained, elastomeric foam is an extremely effective deterrent to biological contamination.Even if closed-cell foam duct liner gets dirty or wet, its smooth surface makes it extremely easy to clean.The same cannot be said of fiber-based duct liners, which are notoriously difficult to clean, and deteriorate more quickly under adverse conditions.While many fiberglass duct liners are now encapsulated with a protective jacket that acts as a vapor retarder, this outer covering is easily punctured.Closed-cell elastomeric foam requires no such vapor retarder or protection. Finally, when fiberglass insulation gets wet, the North American Insulation Manufacturers Association (NAIMA) recommends that it be removed and thrown out as soon as possible to prevent mold and fungi growth. 10 Steps to Prevent Moisture in Piping and Ductwork Moisture needn’t be a problem in a well-designed and maintained HVAC system.The following preventative measures will help facilities eliminate moisture problems and minimize the risk of mold growth. Fully insulate all cold water pipes and fittings and condensate drain pipes with closed-cell elastomeric foam material. Avoid gaps or unsealed seams, and be sure to insulate all fittings, valve stems, etc. Whenever possible, use insulation materials that have non-moisture-absorbing properties—especially on chilled water and refrigeration piping where condensation can become a problem. Fully insulate cold-air supply ducts and air handling equipment. Specify and install adequate insulation thickness to control condensation.Condensation control typically requires greater insulation thickness than thermal efficiency. Carefully monitor indoor relative humidity, keeping RH at 60% or below. Design systems with adequate drainage in mind.This means installing equipment at appropriate pitch for proper drainage, as well as providing for easy access to drain pans so that workers will be more inclined to check for drainage more often. Change filters regularly and inspect for any accumulation of moisture or mold. Clean and inspect air handlers annually and clean ducts every 5 to 10 years.In certain climates and environments, cleaning may be required more often. Seal cooling ducts during the heating season to prevent moisture from accumulating.Dampers are not airtight and therefore should be sealed by taping plastic sheeting over them. Keep It Clean.Keep It Dry.Keep It REAL. We have a lot to learn about mold and its impact on our indoor environments.While we may not fully understand the degree of hazard mold presents, we do know this:Mold has become a serious concern for building occupants.Mold-related litigation and workers compensation claims are on the increase.These are realities that every building owner, engineer, and contractor must face. Proper insulation practices are the owners’ best defense against mold infestation in chilled water, refrigeration, and HVAC systems.Materials that are non-absorbent, fiber-free, and easy-to-clean are the best choice for avoiding mold and its far-reaching consequences.Closed-cell, elastomeric foam provides these properties for longer lasting systems and greater owner peace of mind. 1) MICROBIAL LEVELS ON INTERIOR SURFACES OF VENTILATION DUCTWORK, CLOSED CELL FOAM VS.

Survey Finding: Most Contractors Convert to 13 Seer by Jan 2006

Emerson Climate Technologies, St. Louis, announced that its second quarterly 13 SEER survey shows that while a majority of HVAC contractors (77%) plan to convert to 13 SEER by January 2006, 12% of those surveyed still plan to aggressively sell 10 SEER after the transition deadline. The survey, the second in a series of 13 SEER market surveys that Emerson is conducting over the course of the year, asked HVAC contractors and distributors across the industry questions to gauge their awareness, planning and actions to prepare for the 13 SEER regulation, which goes into effect January 23, 2006. The purpose of the survey is to help provide an accurate picture of the market’s transition, which is paramount to maintaining uninterrupted product delivery and high quality levels as OEMs release their new 13 SEER models to the industry. The survey also shows that, of those contractors taking steps to prepare for the transition, 33% are actually beginning to develop a strategic marketing plan. Emerson plans to conduct the third survey in the series in late summer.
