HVACR Contracting Business.com Magazine’s 70th Anniversary
By Betty Stephens

Contracting mag
In June Contracting Business.com trade magazine celebrated its 70th birthday. It was 70 years ago that Cleveland-area publisher Irving B. Hexter created this publication to serve the refrigeration industry. He called it, “The Refrigeration Industry,”

In 1949, The Refrigeration Industry’s name was changed for the first time to Commercial Refrigeration and Air Conditioning. The change reflected the growing importance of commercial air conditioning as a necessity. The change indicated the growing importance of air conditioning as it surpassed refrigeration in the market. It became the Contracting Business.com magazine in 2009. The magazine was dedicated to the men and women responsible for the systems necessary to keep food fresh on board U.S. Naval ships, military bases, and right here in the U.S.
Over the decades the magazine reported on the trends in the contracting business. The 1950s, air conditioning was used in hospitals to ease the healing of wounded soldiers from the Korean War. By the end of the 1950s air conditioning moved to centralized systems. .
By the 1980s The Department of Energy was created and began making policies that still impact the HVAC industry today. The industry went from construction boom to bust, saw the birth of the gigantic replacement market, and the computerization of business changing forever how contractors operated in the marketplace.
The magazine developed a trivia quiz to celebrate this anniversary. There are 18 questions and each question is worth 5 points. There are four BONUS questions for a total of 20 additional points. There is a total of 110 points. Keep track of your answers, then compare them to the key found at the end of the quiz. Start the quiz on the right side of the screen.

Auto Cooling
The auto cooling system protects the engine from overheating as the vehicle runs. Since the engine burns fuel, it produces energy: one third of it turns into mechanical power, while the rest is transformed into heat. But not all that heat goes straight out of the tail pipe. Even on the hottest summer day, the temperature will never be higher than it is under the hood. If it weren’t for the cooling system, the engine would be damaged by the excessive heat.
The processes in the cooling system, first, the water pump pushes fluid to the engine block to absorb heat. Then, the mixture travels to the radiator, where it is cooled by the fan and the air stream coming from the outside. Once the fluid is cooled, it goes back to the engine, and the operation starts over again. The thermostat controls the engine’s temperature and doesn’t allow the flow of coolant from the engine back to the radiator.
Do It Yourself AC Recharge Kit

Casino Air

Casino Air Quality
BY Betty Stephens

728x90 Get $50 Off Every Home Warranty

Casinos are one of the few public places that allow indoor smoking. They are faced with a unique air quality challenge. In addition to cigarette smoke, gaming facilities must also control malodors related to customer density, food services and restroom facilities in order to encourage guests to stay and play. In the competitive world of casino gaming, allowing an unfavorable smell to drive players away can be costly to business. Most casino operators don’t realize the amount of paper ash, tar, nicotine, and carcinogens that are emitted into the breathing zone from a single burning cigarette.
Casino Atmosphere
The atmosphere in casinos, with or without smoke, is extremely dirty. The constant flow of people in and out creates a variety of pollutants, including bacteria and virus droplets that are passed on to employees. Dirt, perspiration, cologne, perfume, skin flakes, and other human emissions combine to make unacceptable indoor air quality in most gaming environments.

Use of Chemicals
Scented chemicals are used to mask the order from tobacco and other orders in casinos. The uses of scented chemicals that have major health implications associated with them are intentionally being pumped into casinos to mask tobacco smoke odors. Sooner or later their employees can become sick. The utilization of chemically fragrant products through a casino’s ventilation system is not healthy. Laboratory tests commissioned by the Campaign for Safe Cosmetics revealed 38 secret chemicals in 17 name brand products, with an average of 14 secret chemicals per product. The chemicals in commercial fragrances are synthetic compounds derived from petroleum and natural gas, known as petrochemicals. On average, 80% of fragrance formulations are comprised of these chemicals and in some cases, 100% of a formula can be synthetic.

A night of exciting entertainment and sparkling lights is more enjoyable in a freshly scented environment. Removing unwanted odors in crowded places encourages people to stay and play. Keeping guests on the game floor longer and higher revenues are guaranteed. Quality air scents denote a sense of elegance and class to an establishment, and visitors spend more time and money in these places.
Health advocates are warning gamblers that they may be risking their health along with their money when they play at casinos. A study released recently by two area health organizations found unhealthy levels of air pollution on the smoky gaming floors of casinos.

Casinos Exempt from Clean Air Laws
Casinos often receive exemptions to clean indoor air laws. That special treatment has put gaming establishments on the front lines in recent battles over whether to curb or extend legal restrictions on smoking. Nationwide, city councils and state legislatures have fought over including casinos in their smoking bans.
Casinos insist that their business relies disproportionately on smokers, while health advocates point to profitable casinos in states where smoking isn’t allowed.

The Problem with Cigarette Smoke
Cigarette smoke is a very difficult pollutant to remove from the air. This is because there are two major components to the smoke. The first problem of cigarette smoke is the many toxic gasses produced by burning cigarettes. Ammonia gasses, Carbon Monoxide, and phenol are just a few of the dozens of toxic gasses produced when cigarettes are burned; these gasses have foul odors and are highly toxic.
The second problematic component of cigarette smoke is the very high level of tar solids that are disseminated into the air when cigarettes are burned. This petroleum based tar clouds the air and sticks to every surface of the room. This tar discolors paint and it also has a terrible, sickening odor.
Summary
There are air technologies that can eliminate more than just tobacco odor and smoke. Using activated oxygen generated by molecular oxidizers can sterilize the air handlers and existing ductwork while killing harmful microorganisms such as Legionella, mold, and mildew in the process. 75% of people in the U.S. don’t smoke, and most of them are bothered by second hand smoke when they go to public places. So Casino patrons will breathe and feel better in an establishment if it is smoke free.

Meeting Room – Cold Temperatures

Cold Air in Business Meetings
By Betty Stephens

Cold Air in business Meetings do they do that to keep people awake or kill germs?
As summer-clad office workers, conference attendees and event guests stream into meeting rooms and reception halls nationwide, many are met with a blast of Arctic air. “Over-chilling” is one of the top complaints of meeting planners, says Donald Young of the International Facility Management Association.
Meeting planner Steve Kemble of Dallas sees it all the time in the surveys that conference attendee’s mail in. “If two or three weeks later they’re still thinking about the temperature, then that’s an issue.” It’s so frustrating “to plan a fabulous program, with a speaker you paid $100,000 for, and all you hear from people leaving is ‘Brrr, it was freezing in there!’ ”
Folks in charge of thermostats say this: You have to pre-chill so you don’t overheat. “We always make it as cold as possible prior to the event starting, because it’s a better experience,” says Eric Whitson, director of sales at the National Conference Center in Lansdowne, Va. That means about 65 degrees. “At first it’s going to be chilly to most people who enter, but the temperature goes up as those numbers build.” It should end up at about 70 degrees, he says.
“Once it gets too hot, you can’t cool the room down,” says Elise Enloe of Attention to Details in Oviedo, Fla. Chilling is essential because “once you put 500 sweaty bodies in the room, all drinking and dancing and giving off body heat, you can’t do anything about it.”
Engineer’s Response
There’s only one problem with this logic, says Kent Peterson, past president of the American Society of Heating, Refrigerating and Air-Conditioning Engineers: It is wrong. The whole idea of getting a room cold before the people come flies in the face of ASHRAE’s 114 years of experience, Peterson says.
If you have to pre-cool a room, it’s because something’s seriously out of whack with the air-conditioning system, he says. “You should start out at 74 degrees, and as the temperature starts to rise up to 78, the air conditioning system will turn on and keep the temperature down.”
And no excuses about the addition of all those heat-producing bodies. That should have been taken into consideration when the system was designed, he says. “Cooling load calculations” are based on how many people are in the space and what activities they are to be engaged in, whether it’s dancing or sitting. “Our industry is very good at doing these calculations,” he says.
Peterson says many rooms are chilled to dehumidify the air. “Instead of implementing an energy-efficient design that has a dedicated system to dehumidify the outside air, they’re running their air-conditioning system at full load in order to reduce the amount of moisture.”
Keep People Awake
Canadian business speaker Cameron Herold asks for it. Speakers “get all ballrooms set colder during the daytimes (after lunch sessions especially) to keep people awake.”
Meeting planner Debby Goedeke of the Albany County Convention and Visitors Bureau in Albany, N.Y., says clients often ask that ballrooms and meeting rooms be kept colder so that attendees will stay alert. They want their attendees’ cold.
Eric Papp of Tampa-based Generation Y Consulting is in that camp. He speaks about 13 times a month in hotels and likes to have it “a little cold because it keeps people alert.” Cold air does little to kill germs.
Cold Employees
It was found that cold employees weren’t just uncomfortable, they were distracted. When the body’s temperature drops, people expend energy keeping themselves warm, making less energy available for concentration, inspiration, and insight.   Overly air conditioned offices are one of those conundrums many people have to face on a daily basis. It is sweltering outside. Like so hot that the shower you took a half hour ago was pointless and you are contemplating just pouring a bucket of water on yourself before you go to your desk. But then you get inside and it feels great! However, after a little while you realize you have goose bumps all over your arms–and need a sweater. Actually, more like a jacket. And a pair of gloves wouldn’t hurt.
A study found that Cold employees weren’t just uncomfortable, they were distracted. The drop in performance was costing employers 10% more per hour, per employee. And it’s not just performance that dips, our impression of the people around us changes. In a study reported in the journal Science, psychologists uncovered a link between physical and interpersonal warmth. When people feel cold physically, they’re also more likely to perceive others as less generous and caring. They view them as cold.
When people are warm, on the other hand, they let their guard down and view themselves as more similar to those around them. Researchers at UCLA even states that brief exposure to warmer temperatures leads people to report higher job satisfaction. The same area of the brain that lights up when we sense temperature–the insular cortex–is also active when we feel trust and empathy toward another person. When we experience warmth, we experience trust. And vice versa.

728x90 Get $50 Off Every Home Warranty

McQuay International is a global corporation that designs, manufactures and sells heating, ventilation and air conditioning (HVAC) products, systems, parts and services for commercial McQuaybuildings. Since 2006, McQuay has been a subsidiary of Daikin Industries, Ltd. McQuay world headquarters are located in Minneapolis, MN, USA. Products are sold by a global network of sales representatives and distributors.
McQuay was incorporated in 1933 with manufacturing and headquarters in Minneapolis, Minnesota. Initial success was built on the first classroom unit ventilator and the first hermetic compressor for air conditioning use. During 1941-1945, McQuay manufacturing facilities were converted to support the U.S. war effort. In the later 1940s and 1950s, McQuay products and sales grew as the demand for commercial air conditioning increased. The U. S. manufacturing facilities were expanded to meet this demand.
McQuay became a multi-national corporation during the 1960s by beginning overseas sales and licensing operations in Canada, England, Scotland, and Australia. In 1965, McQuay established a new division in Italy, McQuay Europa, to manufacture 50 Hz equipment.
Through mergers and acquisition in the 1970s, ‘80s, and ‘90s, the McQuay product line grew to include more types of commercial HVAC and large capacity equipment, as air conditioning became viewed more as a requirement than a luxury in buildings of all types. In 1984 it was acquired by Snyder General.
In 1992 McQuay, received the Stratospheric Ozone Protection Award from the U.S. Environmental Protection Agency in recognition of McQuay being the first to design and manufacture chillers with HFC-134a, a refrigerant with no ozone depletion potential.
In 2006 McQuay, was acquired by Daikin Industries, a global manufacturer of both commercial and residential air conditioning equipment based in Osaka, Japan. Daikin had annual sales of $13 billion in 2009. Daikin was named one of the 100 most sustainable corporations for three years in a row by Corporate Knights, Inc., from 2007 through 2009. As a Daikin Industries group company, McQuay is part of the largest HVACR Company in the world.
With more than six million square feet of manufacturing facilities and offices in more than 75 countries, they are uniquely positioned to make sure their products and services are always within Customers’ reach.

Hermetic Compressor for Air Conditioning

Hermetically Sealed Compressors used in refrigeration systems are often described as being hermetic, open or semi-hermetic, to describe how the compressor and motor drive are situated in relation to the gas or vapor being compressed. In hermetic compressors, the compressor and motor driving the compressor are integrated, and operate within the pressurized gas envelope of the system. The motor is designed to operate in, and be cooled by, the refrigerant gas being compressed. The hermetic uses a one-piece welded steel casing that cannot be opened for repair; if the hermetic fails it is simply replaced with an entire new unit.

728x90 Get $50 Off Every Home Warranty

Portable Air Conditioner or Spot Cooler
A spot cooler is a portable, self-contained air conditioner used to cool a space. The entire unit is portable and can be moved to another space, if needed. The spot coolers are completely self-contained and do not have condensing units that need to be installed outside, like at the house.

Air-cooled portable air conditioning systems are most often the system of choice for end-users and industry professionals. The fact that air cooled portable air conditioning units can be installed almost anywhere – usually in minutes – explains their popularity. They can be used for temporary cooling as needed.

Spot cooling products can go with you in the yard while doing landscaping or gardening and in the garage for cooling home projects. Factories and warehouses benefit from the extremely low operational cost (less than $1.00 per day) of these powerful units, while keeping workers cool, thus increasing productivity and employee comfort.

Spot/Portable air conditioner systems are often used to provide cooling relief outdoors and at events. Units are entirely self-contained, enabling quick and easy set-up, installation and breakdown at all events. The portable air conditioners are both ETL listed for outdoor use. This ensures safe cooling under strong sunlight and high humid conditions.

 Brings outdoor cooling to areas area thought impossible to air condition.
 Spot cooler can produce a comfortable environment, even in the hottest and stickiest of seasons.
 Protect participants from the dangers of extreme heat during events.

The Dallas Cowboys were the first NFL football team to use portable units for their summer workouts and the early season games at Texas Stadium. Some claim that, “Thanks to portable cooling that the Cowboys won the Super bowl! This, of course, is not a claim that can be proven, but may not be too far from reality.

The same is true for athletes in training, construction work, and numerous other jobs in warehouses, factories and work areas where the temperature is hot. Working in a cool environment improves the efficiency of workers. Employees stay more alert and become less tired.

PTAC’s, Split Ductless Systems

PTACs – Split Ductless Systems    By Betty Stephens

PTAC

728x90 Get $50 Off Every Home Warranty

The System
PTAC (packaged terminal systems) are also known as wall-split air conditioning systems or ductless systems. These PTAC systems which are frequently used in hotels have two separate units, the evaporative unit on the interior and the condensing unit on the exterior, with tubing passing through the wall and connecting them. This minimizes the interior system footprint and allows each room to be adjusted independently. The terminal package is the condensing unit located on the exterior and includes the compressor, condenser and condenser fan. The other terminal package is the evaporative unit located on the interior and handles air cooling and distribution. The internal evaporative unit includes the fan, expansion valve and evaporator coil.
PTAC system may be adapted to provide heating in cold weather, either directly by using an electric strip, gas or other heater, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air conditioner into a heat pump.
Cost
While room air conditioning provides maximum flexibility, when used to cool many rooms at a time it is generally more expensive than central air conditioning. The primary disadvantage of ductless air conditioners is their cost. Such systems cost about $1,500 to $2,000 per ton of cooling capacity. This is about 30% more than central systems and may cost more than twice as much as window units of similar capacity.
An additional possible disadvantage that may increase net cost is that ductless systems may sometimes not be eligible for energy efficiency rebates offered by many electric utility companies as part of an incentive program to reduce summer cooling load on the electrical grid.
Efficiency
Ductless systems offer much higher efficiency (up to 27.1 SEER on some systems). Today’s brands include Aircon, Carrier, Daikin, Klimaire, LG, Mitsubishi, Sanyo, Fujitsu and YMGI.
Most ductless (split system) air conditioners still typically provide cooling to a single room or interior zone, just like a window air conditioner or PTAC; but more powerful outside units are becoming more and more available, supporting cooling of ever-more interior zones. Advantages of the ductless system include smaller size and flexibility for zoning or heating and cooling individual rooms. Flexible exterior hoses lead from the outside unit to the interior one(s); these are often enclosed with metal to look like common drainpipes from the roof. Those enclosures can be painted to match the color of the house.
If your goal is to create a quiet, comfort controlled room, or simply want to heat or cool an area without expensive ductwork, the ductless systems set a new standard for efficiency, great looks and comfort.

Target Hacking Attack Linked to HVAC Contractor’s Computer

Hacking Target
By Betty Stephens

Target

728x90 Get $50 Off Every Home Warranty

The hackers who stole millions of customers’ credit and debit card numbers from Target may have used a Pittsburgh-area heating and refrigeration business as the way to get in through a back door. Experts believe the thieves gained access during the busy holiday season to about 40 million credit and debit card numbers and the personal information including names, email addresses, phone numbers and home addresses of as many as 70 million customers.
Investigators appear to be looking at that theory. It shows how vulnerable big corporations have become as they expand and connect their computer networks to other companies to increase convenience and productivity. Fazio Mechanical Services, a contractor that does business with Target, said in a statement Thursday that it was the victim of a “sophisticated cyber attack operation,” just as Target was. It said it is cooperating with the Secret Service and Target to figure out what happened.
President Ross Fazio confirmed that the U.S. Secret Service visited his company’s offices in connection with the Target investigation, Fazio Mechanical also has done refrigeration and HVAC projects for specific Trader Joe’s, Whole Foods and BJ’s Wholesale Club locations in Pennsylvania, Maryland, Ohio, Virginia and West Virginia.
It’s not immediately clear why Target would have given an HVAC company external network access, or why that access would not be cordoned off from Target’s payment system network. But according to a cyber security expert at a large retailer stated it is common for large retail operations to have a team that routinely monitors energy consumption and temperatures in stores to save on costs and to alert store managers if temperatures in the stores fluctuate outside of an acceptable range that could prevent customers from shopping at the store.
The new details illustrate what can go wrong with the far-flung computer networks that big companies increasingly rely on. “Companies really have to look at the risks associated with that,” said Ken Stasiak, CEO of Secure State, a Cleveland firm that investigates data breaches. Stasiak said industry regulations require companies to keep corporate operations such as contracts and billing separate from consumer financial information.
Since Target disclosed the breach, banks, credit unions and other card companies have canceled and reissued cards, closed accounts and refunded credit card holders for transactions made with the stolen data. A lawsuit has been filed seeking class-action status on behalf of financial institutions nationwide that have spent time and money helping customers deal with the effects of the data breach.

Propane (LP) Shortage

LP Liquid Propane Shortage
By Betty Stephens

Propane tank

728x90 Get $50 Off Every Home Warranty

The price of the fuel that’s used to heat many north Iowa and southern homes has reached nearly $5 per gallon, and it’s leaving some people wondering how they’ll pay for their LP and many of them are now turning to local lawmakers. Some 14 million households use the liquefied gas to heat homes, especially in upper Midwestern states such as Michigan and Ohio, where the shortages have had the most impact.

The shortage has been blamed on a combination of a wet harvest and an extremely cold January but many people question that, saying he believes there’s more to the story. The U.S. has exported so much LP to Europe that Europe is actually sending us ships back to the East coast full of LP because the European reserves on LP are full.
In addition to the weather, inventories have also been stretched by short-term logistical problems and a long-term shift toward exporting more liquefied petroleum gas (LPG), production of which has surged due to the shale revolution.
Demand has been boosted by the combination of record freezing weather at the start of this year and a late, wet, record corn harvest last October and November, when large quantities of propane were used to dry out crops. Propane stocks have been drained and prices in the region are the highest since at least 1990. The industry is doing is literally working round the clock to move propane from where it is, in the large storage facility in Texas, using trains and trucks, pipelines and barges to where it is needed.
Prices
Prices have spiked for the fuel that nearly 6 million U.S. households rely on for home heating. Nationwide, propane prices averaged $2.86 per gallon last week, up 17% from the same period a year earlier, according to the U.S. Energy Information Administration. Prices are even higher in some regions. Residential customers in New York State, for example, paid an average of $3.28 a gallon for propane last week, up from under $3 a gallon in December and 20% higher than at this time last year.

Prices are likely to go even higher as another blast of extreme cold weather is expected. Temperatures will be 10 to 25 degrees below average across much of the country. Temperatures below freezing could extend far south.
