Boston Cooler or cooler Boston? Either is better than global warming!

Wondering about what global warming really means to you? Wonder no more, but you might want to brush up on your conflict resolution skills, fix yourself a Boston Cooler and keep your air conditioner in good working order. Researchers at the University of California Berkeley and Princeton University have released a research report that shows that even relatively small increases in temperature have a profound effect on human behavior.

The researchers examined the effect of temperature increases and drought on violence around the world and found that even small increases in temperature produced measurable increases in violence directed toward individuals, violence within a culture (such as wars, riots, and other societal conflicts), and civic collapse.

The study examined 27 regions around the globe, and researchers found that their conclusions held true in all 27 locations. According to the scientists, there is a direct correlation between increased violence and increases in air temperature. There is also a predictable increase in violence during drought conditions.

According to the study, as the global average temperature rises, we can expect more conflicts, wars and an increased incidence of violence against individuals. A global rise in temperature of about 5°F increases the rate of large-scale conflicts and wars by 50%.

For August, forecasters are predicting a respite from last month’s record-breaking heat in Boston, but the effect of rising temperatures on people is clear: cooler heads prevail when cooler temperatures do. Over time, keeping your air conditioner in good repair will become more important for personal comfort.

Political Agreements Mean Changes For Home Air Conditioners

In the last several weeks, I’ve posted a lot of information about air conditioner efficiency, and how to keep your air conditioner running well over time. I’ve also posted information about the rising cost of recharging older air conditioning units that use a refrigerant known as R-22. While it’s easy to find arguments on both sides of the question about the efficiency and desirability of R-22 as a refrigerant, it’s not always so easy to understand why R-22 is being taken off the market.

R-22 falls into a class of refrigerants that has been identified as harmful to the Earth’s ozone layer. The largest known “hole” in the Earth’s ozone layer is concentrated over Antarctica. Certain chemicals, known as halogenated hydrocarbons, deplete the ozone layer and decrease the protection the Earth’s atmosphere offers against solar radiation.

In 1987, many countries began to sign on to a global treaty called the “Montreal Protocol On Substances That Deplete The Ozone Layer,” referred to in short as “the Montreal Protocol.” This treaty aims to phase out the use of chlorofluorocarbons (CFC) and hydrochlorofluorcarbons (HCFC), to prevent harmful substances from entering the ozone layer. R-22 is considered a HCFC.

As of 2010, manufacturers may not ship new air conditioning units that are charged with new R-22 refrigerant. New R-22 is still available as a recharge refrigerant for existing units. Manufacturers are skirting this portion of the agreement by shipping “dry-charged” units, or units filled with nitrogen instead of R-22. Once the unit is installed, the installer “re-charges” the unit with new R-22. By 2020, however, even recharging with R-22 will be limited to the use of recycled or reclaimed R-22, and no new R-22 will be manufactured anywhere.

So, what is the current alternative to R-22? A refrigerant known as R-410a is currently used as a substitute for R-22. R-410a works at a higher pressure than R-22 does, and it isn’t possible to use R-410a as a direct substitute for R-22. In other words, if your air conditioner was designed to work with R-22, you can’t simply recharge the unit with R-410a instead.

R-410a is also classified as a HCFC, but unlike R-22, it doesn’t have the same ozone-depleting consequences that R-22 does. Unfortunately, R-410a does contribute to global warming, so the plan is to eliminate R-410a from use with other HCFCs, according to the timetable established by the Montreal Protocol.
Consumers should be aware that air conditioners have become a lot more efficient in the last 10 years. Replacing an older air conditioner that is still in good working condition might make economic sense when the replacement unit is significantly more efficient than the existing one. Consumers will need to factor in the cost of recharging (which will become significantly more expensive as R-22 supplies decline) an existing air conditioner when considering possible replacement. Additionally, it will become harder to replace older, R-22 units over time as more manufacturers adopt R-410a designs.

Fortunately for consumers, R-410a performs about as well as R-22 does in most circumstances, including those typically encountered in Boston. In any case, consumers should work only with certified technicians when it comes to recharging air conditioner units and recovering R-22 refrigerant.

Insulating Boston Plumbing Can Save You Money

If you’re looking for an easy way to save money and improve the performance of your Boston plumbing system, consider insulating your pipes. Insulation is highly cost-effective, easy-to-do and can help your hot water stay hotter and your cold water stay colder. Insulting your pipes also doesn’t take any special equipment or tools and the task can be completed in just a few minutes.

In terms of energy efficiency, a significant portion – as much as 30% – of energy loss occurs in pipe and duct runs. The amount of loss is proportional to the length of the run. To combat energy loss, add specially formed pipe insulation, which can be found at your local home improvement or hardware store. Pipe insulation is pre-formed and should have an R-rating of 3 or more. Using better insulation is especially important if your pipes reside in or near your home’s exterior walls.

You can also use regular fiberglass “batt” insulation (with an R-value of 7 or higher) to wrap around pipes, but you’ll need to use protective equipment for your hands, face, clothing and eyes if you go this route. The preformed pipe insulation is the preferred solution if you have a choice.

To apply pre-formed insulation, simply open the insulation tube along the pre-cut split that runs the length of the tube and wrap it around the pipe, like a cuff. You’ll need to break the insulation around joints and valves. If you’re using the batt type insulation, you’ll need to cut the insulation to length, wrap the pipe and secure the insulation with tape or some other binding.

Any pipe – hot or cold – that runs in or near an exterior wall should be insulated. This includes any pipes that feed outdoor spigots and sprinkler systems. After those pipes are done, the next prime candidates are your hot water pipes. You can reduce energy consumption by insulating these, but you can also realize other benefits by insulating your cold water pipes, too.

When there is a significant difference in temperature between the cold water in the pipe and the surrounding air temperature, your cold water pipes will act like a condenser; it will naturally remove moisture from the air. This phenomenon is known as “sweating” and may cause your cold water pipes to drip this condensed moisture along the horizontal runs.

By insulating your cold water pipes, you can control the condensing action, and keep the standing water in the pipe colder – and more refreshing on a hot day!
