The Composition of Snowflakes: Are No Two Alike?

Thursday, December 25th, 2014

“No two snowflakes are alike.”

This is a statement nearly every schoolchild has heard at least once, either while crafting unique snowflakes with a sheet of folded paper and some scissors or while learning a lesson on the science of snow. While even most scientists don’t quite understand what causes a snowflake to form such complex and beautiful columns and points and branches, one thing is for certain, the composition of snowflakes guarantees that no two will ever be identical.  However, it is possible for two snowflakes to appear to be nearly exactly alike.

A snowflake begins to form when a piece of dust catches water vapor out of the air. Water is created when two hydrogen molecules attach to an oxygen molecule. The two hydrogen molecules are angled from one another in such a way that they form a hexagonal shape when they come together during the freezing process; thus, a snowflake begins as a simple hexagonal shape or as layers of hexagons called diamond dust. The emergent properties that follow from the original hexagon are what differentiate one snowflake from another, as the humidity, the temperature in the air, and many other factors (some of which remain unclear to scientists) allow each snowflake to form in an entirely unique way with a seemingly endless variety of shapes.

However, in 1988, a scientist named Nancy Knight claimed to have located two that were the same while studying snowflakes as part of an atmospheric research project. And it appeared to be so; when put under a microscope, the emergent properties looked nearly identical. But while it is feasible that two snowflakes can appear to be exactly alike on the outside, they are never identical on an atomic level. Deuterium is an atom that appears attached to about one in every 3000 hydrogen molecules in the air. Because there are millions of atoms that make up a snowflake, the random assortment of deuterium in any two snowflakes—even in two that so very closely resemble one another—simply cannot be the same.

Here at Air On Demand, we’d like to remind you to grab a cup of cocoa and relax with your family this holiday, perhaps by crafting some unique snowflake creations of your own. We wish you a very happy holiday season, from our family to yours!

What Are Some of My Options for Amana Air Conditioners

Wednesday, December 17th, 2014

So you need a new air conditioning unit but are unsure of how to choose from all of the brands and products available out there. At Air on Demand, we’d like to help you out with part of that equation. Amana has been around since 1934, and this company continues to set the industry trends and develop the innovative technology used for comfort systems around the world. An Amana air conditioning system can bring you lasting comfort and reliability right in your own home or in a commercial setting. Discover your options in our brief primer on the Amana air conditioners available in Richmond Heights.

Products

When you choose from the Amana line of products, you can get a conventional air conditioning unit with an outdoor unit and choose from their line of quality indoor air handlers. These units provide superior comfort and efficiency, variable speed settings, and more. Ask your technician about Amana’s entry level ASX line of air conditioners for residential homes just starting out with a whole-home air conditioning system, or consider choosing from the ASXC line for the best in efficiency and performance Amana has to offer.

Amana even has a line of high quality commercial units if you’re shopping for AC for a small or large commercial property. This includes packaged rooftop units which remain out of sight of clients, customers, employees, and tenants, while keeping the whole building conditioned to your needs.

Efficiency

Furthermore, Amana offers their products in a wide range of efficiencies, with some units boasting a SEER greater than 18. The SEER (Seasonal Energy Efficiency Ratio) of a unit is displayed on any air conditioner sold in the U.S. A higher SEER means a more efficient system, which will amount to greater savings as time goes on. However, you can choose an Amana system with a lower SEER if the cost of installation is a concern.

Air on Demand is proud to be a certified dealer of Amana air conditioners. Learn more about the benefits of these air conditioning systems, schedule repairs, or receive a thorough maintenance inspection by calling us today and asking about Amana air conditioners in Richmond Heights.

Is Bigger Better When It Comes to Pool Heaters?

Wednesday, December 10th, 2014

*Air On Demand no longer offers pool heater services. Please visit our service page to learn more about our Florida air conditioning services.

A pool heater can extend the pool season for your home: you will get much more use from your recreational pool during the year with the right heating system keeping it warm through the cooler months. When you call Air on Demand for pool heater service, we will make the effort to see that you have a comfortable pool your family and guests can enjoy around the year. We offer many services for pool heaters in Miami, FL, including installation work that will ensure a system that works at peak efficiency.

The Tricky Business of Sizing a Pool Heater

One of the important parts of putting in a pool heater is making sure it is the correct size to maintain the comfortable temperature you want. For most people, the ideal warmth for a pool is between 84° and 86°F. The main obstacle with heating a pool is not the volume of water in the pool, but the amount of heat loss through evaporative cooling that occurs across the service. The job of the pool heater is to replace the heat loss that occurs across the surface, and so the surface size of the pool and the average outdoor temperature are the most crucial factors that a professional installer needs to consider. Average wind levels are also important, since wind increases the amount of evaporative cooling.

In cases of heating the interior of a home, HVAC installers must find a heating system (furnace, boiler, heat pump, etc.) that provides sufficient heat for comfort, but not too much that the system will start to short-cycle, i.e. turn itself off prematurely because it raised the indoor temperature too fast. The same isn’t true of pool heaters, however. A pool heater can be undersized: if it cannot replace the heat lost through evaporative cooling, the pool’s temperature will fall below the ideal. However, there is no such thing as oversizing a pool heater. The larger the heater’s output, the faster it heats the water in the pool, and it will not begin short-cycling.

Nonetheless, although a larger pool heater doesn’t pose the same problems that an oversized indoor heater does, it will cost you more money to install a larger heating system. You want to have your pool heater land in the right zone for comfort and your budget plans. This is why professional installers are key. They will make the measurements necessary to determine the minimum BTU output to reach the 84–86° range based on surface area and rate of heat loss, and then help you decide on the efficiency, fuel type, and size of heating system that meets your budget.

How Long Does Pool Heater Installation Take

Wednesday, December 3rd, 2014

*Air On Demand no longer offers pool heater services. Please visit our service page to learn more about our Florida air conditioning services.

Choosing to install a new pool heater is a great way to get a return on your initial investment. Pool heaters give homeowners the opportunity to enjoy their swimming pools year-round without having to bear with the colder temperatures. So if you’ve decided to install a pool heater but haven’t scheduled installation yet, it may be because you still have a few questions about the process. And while the main question on most homeowners’ minds involves cost, others often ask the question: how long will installation take?

Of course, there’s no simple answer to this question. In general, you’ll have to have a technician come look at your pool and discuss your options before they decide on a plan of action. You’ll also need to choose the type of pool heater you’d like to use. You can choose between energy efficient heat pumps or gas-powered models. Most technicians recommend a heat pump as these use very little energy, requiring refrigerant and a pump to move heat from the outside air into your swimming pool. You should give yourself plenty of time to pick the right option for you and make sure a technician sizes the unit for your pool.

Most types of pool heaters will involve outside installation of some sort, and if you need to mount your outside unit in concrete (which is usually the standard process to install a heat pump pool heater), you should allow for an additional day or two. All in all, pool heater installation can take a single day or it can take a few days—it is entirely contingent on your individual needs.

After your pool heater is installed, you’ll still likely have to wait a few days before you can use it although, again, this depends on the size of the pool. It can take as many as three days to heat up a larger pool, if the outside temperature is much cooler than your desired pool temperature. If you’re hoping to take advantage of your pool heater before cooler temperatures start to kick in, call Air on Demand to learn more about how professionals install pool heaters here in Miami.
