Energy Star was created in 1992 by the Environmental Protection Agency and the Department of Energy during the Clinton Administration. Initiated as a voluntary labeling program designed to identify and promote energy efficient products, Energy Star began with labels for computer and printer products. In 1995 the program was significantly expanded, introducing labels for residential heating and cooling systems and new homes. Energy Star is now the international standard for energy efficient consumer products. Australia, Canada, Japan, New Zealand, Taiwan and the European Union have all adopted the program. Devices carrying the Energy Star service mark, such as computer products and peripherals, kitchen appliances, buildings and other products, generally use 20%-30% less energy than required by federal standards.

Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. By choosing ENERGY STAR qualified heating and cooling equipment and taking steps to optimize its performance, you can enhance the comfort of your home while saving energy. Saving energy helps you save money on utility bills and protect the environment by reducing greenhouse gas emissions in the fight against climate change. Air conditioning is the removal of heat from indoor air for thermal comfort. ENERGY STAR qualified central air conditioners have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings, making them about 14% more efficient than standard models. ENERGY STAR qualified room air conditioners use about 10% less energy than conventional models.

The ‘Apparatus for Treating Air’ (U.S. Pat# 808897) granted in 1906, was the first of several patents awarded to Willis Haviland Carrier. The recognized ‘father of air conditioning’ is Carrier, but the term ‘air conditioning’ actually originated with textile engineer, Stuart H. Cramer. Cramer used the phrase ‘air conditioning’ in a 1906 patent claim filed for a device that added water vapor to the air in textile plants – to condition the yarn. In 1911, Carrier disclosed his basic Rational Psychrometric Formulae to the American Society of Mechanical Engineers. Today, all fundamental calculations in the air conditioning industry have the basis of Carrier’s formula. Carrier’s so called ‘flash of genius’ came while waiting for a train. On a foggy night, he was going over in his mind the problem of temperature and humidity control and by the time the train arrived, Carrier had an understanding of the relationship between temperature, humidity and dew point.

The actual process air conditioners use to reduce the ambient air temperature in a room is based on a very simple scientific principle. The rest is achieved with the application of a few clever mechanical techniques. Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas it absorbs heat in a process called phase conversion. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils. The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils. As the gas cools, it changes back to a liquid, and the process starts all over again.

It’s simple to see that there are two distinct things going on in an air conditioner. Refrigerant is chilling the indoor air, and the resulting gas is being continually compressed and cooled for conversion back to a liquid again. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils.

In 1928, Carrier developed the first residential ‘Weathermaker’, an air conditioner for private home use. The Great Depression and then World War II slowed the non-industrial use of air conditioning. After the war, consumer sales started to grow again. While Carrier did not invent the very first system to cool an interior structure, his system was the first truly successful and safe one that started the science of modern air conditioning.

Earning the ENERGY STAR means HVAC supplies and products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. By choosing ENERGY STAR qualified heating and cooling equipment and taking steps to optimize its performance, you can enhance the comfort of your home while saving energy. Saving energy helps you save money on utility bills and protect the environment by reducing greenhouse gas emissions in the fight against climate change. Energy prices have become a hot news topic and a major concern for consumers. If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit such as Goodman equipment, which has earned the ENERGY STAR.

Useful Guides Before You Undergo a Cosmetic Surgery

by

Cosmetic surgery arose to address issues for body improvement and restoration. For instance, if a person suffers from a crooked-looking nose, plastic surgery addresses this through rhinoplasty, a surgery that entails the repair of the nose to restore it to its previous form. The same principle also goes for breast augmentation, as cancer patients may need this procedure to get back lost volumes on their breasts.

In the 1960 s cosmetic surgery emerged as a means to improve physical image. People began to see this procedure as a way to look attractive, and by the 1980 s to the 1990 s more people came to understand it as an acceptable body enhancement.

If you re aiming for cosmetic surgery, Phoenix may be a good place to start because the city has competent surgeons. As the city enjoys a low-profile image in the cosmetic surgery world, prices here remain affordable too. If you have decided to undergo surgery here, try the following tips to help you better.

Make sure to settle all financial issues. One of the issues that one carries to the surgery once they undergo a

rhinoplasty Phoenix

for example is money. To put this issue aside, make sure that you already talked with the necessary parties like the human resources personnel and insurance agent. Your insurance agent helps you make sure you are paid even when you re resting from the operation. The insurance agent will determine if you ll get partial or full coverage for the surgery.

Tell your family about the surgery. If you re thinking about getting a

Phoenix rhinoplasty

but wish to keep it from co-workers, then that s alright because, who wants office gossip anyway? However, keeping the surgery from your family might be a bad idea since you ll lose mental and emotional support. Just have a conversation with your family to inform them of the date of your surgery and its location so they ll know where you ll be headed and where to visit just in case.

Make necessary arrangements for post-op care. If possible, consider getting someone to care for you after the surgery, be it a trusted friend or relative. Surgeries like

Phoenix breast augmentation

may render you unable to lift your arms for days thus preventing you from dressing yourself. Furthermore, you also won t be able to do your regular activities like cleaning, grocery shopping and cooking for days so it s best to have these issues addressed too.

Healthcare is the general term used for the entire area of prevention, treatment and cure of illness and disease using the services of medical experts and resources. The World Health Organizations definition is a little different and refers more to the prevention of illness and services to encourage this, in addition to intervention that should be available to a single person as well as a whole population. The organized provision of such facilities may constitute a healthcare system.The term health care has not always been used though and prior to this is it was often just referred to medicine or the health sector but this was used more by English speaking nations. In most developed nations and many developing nations healthcare is provided to everyone regardless of their ability to pay. This first begun in the UK a few years after the end of World War 2 in 1948, and became the first healthcare service set up and run by a administration.Instead a system of compulsory government funded health insurance with nominal fees can be provided, as with Italy, which, according to The World Health Organization, has the second-best health system in the world. Canada and Australia have both begun similar systems and have been running since almost twenty and the 1970’s respectively both going by the name of Medicare. The main nations that do not support this general healthcare service are The United States and South Africa, although they are making reforms to their health service. health care professionals are dedicated to preventing illness and disease mainly, but also to treat and protect the long term health of their patients.Worldwide, over recent decades, there has been a huge growth in the sum of money spent on health care and it is now one of the fastest growing sectors in every developed country with an average cost of ten percent of the gross domestic product. America has seen some of the biggest rises and the figures in 2006 are anticipated to be the same as 2003 with over 15 percent of GDP – it is currently the biggest in the world but the increase by 2016 is expected to be almost twenty percent.currently in the America over 180 million citizens are looking for health care and it will be no surprise to learn that it is top of all concerns for those in and seeking work. A issue which came to a head when General Motors was seriously considering bankruptcy over the strain its health car plan was putting on the company. It was only after negotiations with the unions to reduce certain health benefits and the subsequent sell off of its poorly performing finance division that stopped the unthinkable from occurring.Workers in The United States place this as their number one priority when looking for a prospective employer and often will move to a lower paid position just to improve their medical care. Perhaps it is time healthcare was looked at in a different way and perhaps called health preservation with an accent on fitness and health to ease the need for a top heavy healthcare system which is becoming a global problem.
