How a Room Air Conditioner Operates

A room air conditioner is a small enclosed cooling device that is able to be mounted in a window or through a wall for venting and for air exchange. Recently, there has also been an introduction of portable air conditioning units, which are housed in cases that sit on the floor near a window with a tube for venting. These portable units usually have casters mounted to the bottom of the case allowing them to easily move from one room to another as needed.

The purpose of air conditioning equipment for a room is to cool the air within a small, confined area and they are not intended to be used as a "whole house" air conditioning system. They are most often used in houses or apartments where people are renters; therefore, they are not permanently installed and can be removed and taken to a new location if the occupant moves.

Typically, a room air conditioner will have a control panel mounted somewhere on the front or on top, in order to give the user easy access to the controls. Generally, there are independent controls for setting the target room temperature and for controlling the fan speed for circulating the conditioned air around the room.

Most people are not aware that room air conditioning units do not "technically" cool a room. It is more correct to say that room air conditioners remove the heat from the air and then moves it elsewhere to where the unit has been vented.

A pressurized refrigerant, R-22, flows through the air conditioner unit when it is turned on. While the unit is on, the condenser will pull the refrigerant gas into the air conditioning system and then pressurize it, which raises the temperature of the gas. This heated, high-pressure gas travels next to the condenser coils, which are located on the outdoor portion of the unit where the fans distribute the heat that has collected.

The cooled gas then becomes condensed into a liquid, which moves to the interior part of the room air conditioner to the evaporator coils. At this point, these coils can absorb the heat that is in the room. The fan then moves the air throughout the unit. The thermostat controls the cycling of this process to maintain the desired temperature in the room.

Some room air conditioners have mechanical controls, such as knobs and push buttons. The newer air conditioning units are controlled with electronic touch-pads that tend to provide more functionality and can regulate the mode the units operate in, the temperature set point, a timer for automatic shut off and powering on, and various other conveniences, most of which are designed to make the unit as energy efficient as possible.

In order to help consumers choose the best room air conditioner unit, small air conditioners are rated for their energy efficiency level by EnergyStar.gov, which is a service of the U.S. Dept. of Energy. The Energy Efficiency Rating (EER) is the cooling capacity of the unit, in terms of BTUs divided by watts of electrical power used by the unit. To have an Energy Star rating, a unit has to have an EER that is 10 percent higher than similar models.

Trane Air Conditioning

If you are looking for a quality air conditioner, then Trane air conditioning units are one of the leaders in their field. They manufacture units for residential and commercial use. James Trane is the founder of the company. He came to the United States from Norway in 1864. A plumber by trade, he opened his own store in 1885 in Wisconsin. From the very beginning, he was known for providing good service and quality.

At the beginning, the company was not involved in Trane air conditioning units. They kept the plumbing aspect of the business open until around 1915 when they concentrated on heating products such as low-pressure steam heating units. James' son Reuben who was a mechanical engineer was heavily involved in the progress of the company. During World War II, the company was involved with the US Navy in providing the technology to keep pace with the German war ships. The main component they assisted with was providing the navy ships with a heat exchanger, which proved to be a very important advancement in naval engineering.

During the late fifty's, Trane air conditioning units hit the residential market. This was a major addition to their product line. During the sixties, the company expanded their operation around the world. The majority of their business focused on the large commercial and industrial units.

Air Conditioning Zones

If you are looking at purchasing a central air conditioning (ducted) system, you have probably heard the salesman talking about zones. So what is a zone in relation to air conditioning? What do they do, how many can you have and what do they cost? Below is an essential guide to zoning your new air conditioning system.


1) Function Of A Zone - Zones are usually on or off switches that allow you to either have airflow or restrict airflow down a particular piece of ducting. Zones are important in ducted systems as you can usually only run about half your home at any one time. Zones allow you to choose which rooms you want air to flow to and which rooms you want to restrict airflow to.


2) Convenience - The main benefit of zones is the convenience that they offer. Zones allow you to choose which rooms you want airflow to, and allows you to turn off the rooms that don't require any air conditioning.


3) Energy Savings - Because you can choose which zones to run, zoning also gives you energy savings. By only running the areas that you are actually in, you save on electricity bills as you don't have to run rooms that are not inhabited.


4) Save Money When Running - Because you can run less zones and save on power consumption, ultimately you will also save money on running costs. This means you will have more money for your back pocket.


So that is what a zone is. Next time you get a hvac quote, be sure to tell the contractor that you want lots of zones because of the reasons outlined above.

Portable Air Conditioner Review

Consumers consider electric fans to be the most efficient of all cooling devices. Why? This is because fans use less power compared with air conditioners. However in hot and humid weather or places, air conditioners can give such relief. Trying to cool an entire house will take up more energy so it is still better and more efficient to cool an area where you sleep or work most of the time, by making use of the mobile or portable air conditioner.


If you are still not convinced why portable air conditioner is for you, remember one thing, people who choose to install a centralized air conditioning will never be able to move nor take this when they decide to leave the house. This is the reason having a portable air conditioner is to your advantage.


Next, what is a portable air conditioner? A portable air conditioner just like the standard air conditioner is designed specifically to cool the air inside an area but the only difference is you do not need to install the portable air conditioner to a window or to a wall. Furthermore, you can use portable air conditioners on most rooms and setting this up is fast and easy.


Aside from its cooling capability, the portable air conditioner is an excellent dehumidifier. Since there is less humidity the tendency is you feel a lot cooler and comfortable. This is just one of the things that is so great about portable air conditioners.


Currently, there are a lot of portable air conditioners which are available in the market but don’t forget not all portable units are the same. This means you still need to check the EER, the setup or if the air conditioner has a single or two hoses and of course the prices. It’s true that this type of air conditioner is very convenient because you can move it anywhere but it can be quite expensive. Included below are just a couple of portable air conditioners that may be to your liking.


Here is one of the more efficient portable air conditioner, the Newair AC-12000E. This unit has an energy efficiency Ratio (EER) of 14.4. Any air conditioner with above 12 EER are qualified as efficient. What’s more this portable unit can be yours at $389.95 from Amazon.


Meanwhile, one of the cheapest portable air conditioners is the 7000 BTU Haier HPE07XC6. Experts tell that it works best in very small rooms or in 150-squre-feet or less areas. Most of the moisture removed from the air is removed through the exhaust hose. In addition, you don’t need to throw away the water on the collection cup frequently. The only disadvantage to this portable air conditioner is it can be a little loud. This happens when shifting from cool to fan mode but it is not louder than using several fans at the same time. The Hair HPE07XC6 has an 8.2 EER and measures 21 x 17 x 34 inches. You can purchase this from Amazon and is generally cheaper than the Newair portable air conditioner.

Top Five Home Improvement Ideas to Consider

Home improvement is a very widespread field, with many ideas from which to choose. During the summertime, countless people think about remodeling their homes, making improvements to certain rooms of the house, but are often not sure which improvements to do. Low-cost home improvements that not only improve your home's appearance, but also help you save money in the long run, are the hottest plans currently. I'm writing this to list these ideas and hopefully, help spark your imagination. These are the top 5 home improvement ideas for 2009:

1.) Installing "Green" Technology - Due to the need of almost everyone to save money right now, and because of the increased awareness of the need to save our environment, the top home improvement plan right now is the installing of "green" technology, also known as "going green." This could include such installments as solar panels, power-generating windmills, environmentally-friendly cleaners, energy efficient heating and cooling system, and energy-saving light bulbs. Solar panels may be costly at first, but they will save a huge amount of money in the long run by generating your own electricity. The same goes for the energy efficient heating and cooling system - it will help you save money on your electric bills. Windmills can not only help you generate your own electricity, but they can be made with parts from the junkyard. You can't get much cheaper than that! Also, many of these "going green" improvements will help you qualify for a tax break and help out the environment. It's a win-win situation.

2.) Install a programmable thermostat - This may be a very simple improvement, but don't underestimate it. Installing a programmable thermostat will help save money on your electric bills. How does it do this? Instead of having the air conditioning or the heater running all day, the pre-programmed thermostat only turns on the AC or the heat when the temperature of the house gets too hot or too cold. This keeps the central heating and cooling system from running unnecessarily and, in turn, saves you money.

3.) Re-insulate your home - Making sure your home is well insulated will also help save you money on electric bills. That is because a well-insulated home will not let out cool air in the summer, and it will not let out warm air in the winter. That also keeps hot or cold air from drafting into the house.

4.) Paint or re-decorate your living space - This may seem like a very simple improvement to your home, but it is effective. Painting your rooms and re-decorating in soothing colors and accents will help you relax and want to spend more time in your newly decorated home. Pamper yourself along with the new designs and you will feel like you are at a spa getaway.

5.) Put in a patio - This is probably the most expensive option (unless you have close friends or family who are carpenters) but it is worth the splurge. A patio or a sun deck will allow you to relax and soak up some rays in your own back yard. You can grill out with family and friends, sun bathe on a chaisse lounge, or watch the stars from your patio. The good thing about putting in a patio is that it is actually less expensive than adding a room onto your house. A patio may be a small addition, but it will more than pay for itself with all the hours of relaxation it will afford.

No matter which home improvement idea you decide to choose, the payoff will be well worth it. Even if these ideas aren't what you are looking for, there are many other low-cost home improvement ideas. This year, less is more is the approach to home improvement, and saving money is the best thing.

Duct, Gaffer & Cloth Tape - A Guide to Industrial Tape

One myth about the word Duct Tape comes from World War II, when a tape was manufactured for the US Military to prevent water from getting into ammunition boxes. As the water rolled of the boxes the word was born 'Duct' Tape, as it was a comparison to being like a duck on the water - the water rolls off looking like the feathers are dry. The tape was also widely used to repair army tents as a quick and easy repair for the troops on the move , it was also light and easy to carry.

Since these early years the tape has been used in the building and construction industry for repairing and sealing air and heating ducts. One of the main advantages of using Duct Tape is the tape is made of cloth so it can be torn easily by hand plus it has a 75mm core which allows your hand to fit inside which helps to wrap tape around pipes.

Awnings - Rain Or Shine

In the past, awnings were manufactured by a commercial awnings company but were not rated by wind tolerance. However in today's modern society, awnings or canopies in fact comes in two basic types, either motorized or manually-operated models. The latter is actually operated by hand while the former is powered by electricity. Either way, both types have their own advantages. For a start, these contraptions offer affordability and easy maintenance not to mention the ease of adaptability to almost any deck or patio. This is because the support arms can in fact be angled back against the house itself or better yet, set vertically on the deck or floor of the patio. At the same time, the arms provide the necessary extra support and stability especially for owners who live in places that are very windy. Both types of awnings are also very versatile as attachment of certain accessories is now obtainable.

Aside from the power source, motorized awnings differ from the manually-operated awnings as they have no vertical supports but instead have retracting lateral arms thus fashioning an area with an unobstructed shade. In addition, these awnings are basically operated by an electric motor that is in fact generally hidden inside the roller bar of the awning. The arms themselves essentially open and close the awning easily with just a touch of a switch mounted on a wall making motorized awnings extremely convenient not to mention very classic, simple and beautiful. Retractable awnings are now considerably very trendy with the modern household and building particularly with the increasingly high energy costs. Most owners now prefer to decrease or go without air conditioning and simply make use of awnings and canopies.

At the present, with the many breakthroughs in manufacturing, the modern awning or canopy can now be constructed with a wide array of coverings such as fabric, aluminum, corrugated fiberglass and corrugated polycarbonate. For the reason that strong and high winds can damage an extended awning, there are now improvements with the latest designs. For instance, awning manufacturers incorporated a gadget called a wind sensor to allow the awning to automatically retract in certain weather conditions. Some of today's awnings and canopies offer a wide variety of accessories that not only improves versatility but also increases the usefulness particularly for owners with decks and patios. For instance, awnings can add screen protection and transform your outdoor area into a room that is practically free from pesky bugs. Side screening also cuts down on wind and mist that are coming from the sides of your awnings while patio lights will certainly let you and your guests enjoy the decks during evenings and special occasions. Awnings and canopies have really undergone a transformation and luckily for us, with just a call to an awnings company you can certainly order one that would fit your style and specifications.

With the advent of global climate change there is nothing quite like a canopy, shutter or awning to protect your windows and outdoor areas. Not only are they energy-efficient but they are also considered to be a practical way to stay cool during summer especially if you have a garden with trees about or a pool where you can devise an awning to cover it. If you have a house that has a lot of windows facing the sun, consider a wide awning that retracts when not in use. So when it comes to canopies and awnings, you are now able to acquire one for your home and business, one that not only fits your needs but can also add elegance to the structure. The patterns and colors are much simple yet with a decidedly modern feel and reach out to the homeowner or customer. In the process, those garish and circus-like stripes have definitely been trimmed down and given a mix of conventional yet interesting modern touches.
