A Brief Overview Of Air Conditioning

Most of us take our air conditioning for granted, knowing that we can be cool and comfortable indoors, regardless of how hot it is outside. That refreshing cool air isn’t just in your home; it’s there when you go to the office, shop in a store, eat in a restaurant or take in a movie. Of course, it hasn’t always been that way, and back at the beginning of the 20th century, there was no such thing as A/C. To keep cool, you had to head to the coast or the mountains.

What Exactly is Air Conditioning?

It’s about more than just keeping us cool, although many of us don’t quite understand how it works or what exactly it is. When you have your air conditioner running on a hot day, you are almost creating an artificial climate, one that’s colder inside than the outside. Whether it’s a building or just one room, air conditioning is able to keep the moisture content, humidity and temperature at the ideal level and if needed, add moisture to circulate that cooler air. In much the same way as a hot day causes water drops to condense on a glass of cold water, air conditioning removes water from the air by passing that air over cold pipes.

It’s relatively easy to cool the air in a dry climate. Dry, hot air being blown onto a fiber mat soaked in water, by means of a large fan will provide you with cool air as the water evaporates.

Maintaining the right temperature is important in many industries, and air conditioning has a bigger role to play than just keeping you cool at home or work. Because changing levels of moisture in the air can shrink or stretch cotton, wool, and other fibers, the right temperature is essential in making sure cloth is always high quality. Antibiotic cultures can be damaged if they are exposed to the wrong temperature, and precision instruments or machine parts can even be damaged by excess moisture in the air or on the fingertips of someone handling those parts. The US space program relies heavily on air conditioning keeping facilities and parts at the right temperature, everything from tracking missiles in the atmosphere to manufacturing them. And A/C has made it possible for men to work deep under the ground in mines, such as those in South Africa where diamonds are mined. It would simply be too hot down there without effective air conditioning.

For centuries, some form of air conditioning has been used in hot climates. Woven mats soaked in water and draped across the entrance to homes was a method of keeping cool employed in ancient Rome and Egypt; the water evaporating helped to cool the air inside the dwelling. And a primitive type of fan powered by water was devised by the famous inventor and artist Leonardo da Vinci.

High humidity means there is a lot of moisture content in the air, and it’s this high level of moisture that makes us feel uncomfortable. Many early ideas for air conditioning worked by adding more water to the air which because the water was just soaked up by the air, actually didn’t help much.

Often known as the father of air conditioning, in 1902 Willis Carrier devised a machine that cooled the air and provided low humidity. The owners of a New York based printing plant were having problems with the paper actually changing its size between different print runs, due to fluctuating moisture levels in the air. Carrier solved the dilemma by installing some cold pipes and then drawing the air over them; the excess moisture was condensed and the humidity levels remained constant. An added bonus was that the workers in the factory felt much cooler too.

During the first World War, factories that produced ammunition began to realize the importance of air conditioning. Following the war, the wonderful new invention started to appear in restaurants, stores, and movie theaters and places that had A/C found they were drawing in customers desperate to escape the heat and humidity outside.

Central air conditioning systems which used just one unit to cool an entire apartment, home or office was developed during the 1930s. That same period also saw the introduction of smaller units designed to cool down just one room or a single area. Some homes enjoyed the luxury of air conditioning after World War II, and another development was a system that combined the cooling and the heating unit. These increasingly began to appear in people’s homes and public buildings during the 1940s and ’50s.

So How Does Air Conditioning Work?

Rather like your refrigerator, air conditioning works by using a cooling substance (a refrigerant) to expand and remove the heat from the air. The heat is removed, rather tan cold air added to the air, which is what some people think. A machine is often used to cool the water in schools, public buildings and other large spaces. That cooled water is then delivered through pipes to a set of coils, and the resulting cooler air is then distributed through the building by means of vents and blowers.

One of the most important and useful parts of any air conditioning system is the thermostat. This regulates the temperature to prevent it fluctuating; without it you would find yourself turning your A/C unit on and off constantly to avoid too cold or too hot air. The cooling unit is switched off and on as it is needed, once you have your preferred temperature programmed into your thermostat.

A thermoelectric system is comprised of a number of semiconductors that are installed in pairs. When direct current flows through these pairs, known as couples, they are able to produce heat at one end and cool air at the other end. The heating and cooling effects are reversed when the current is switched to travel in the other direction and the whole thing is called the Peatier effect. This type of unit has a couple of big advantages; it’s extremely quiet and it’s also very small. In the future, this method of cooling will probably be commonplace for every household, although until then we are stuck with the noisier and larger air conditioning units.

Radiant Heating in Focus

Searching for a proven method to warm your home? The Radiant heating method was invented by the Romans. This way of keeping structures warm is an excellent solution for home heating. It totally eradicates the requirement for baseboard heat ducts or radiators. If you have heard about this heating method and are curious to learn more you are in the right place. Keep reading to find out everything you need to know.

The Radiant heating system is fitted below your floorboards, or occasionally inside the walls of your property. The floor heating method is used most often. This method of heating works by using warm water. This water travels through pipes that are below the floorboards in your property. Once the tubes warm-up, the floors follow suit along with the remainder of your living space. The kind of flooring that is on your property at the moment is irrelevant. Radiant heating is great because it can be used on any kind of floor. Examples include hardwood flooring, carpets, slate, ceramic tiles, linoleum, and concrete. This method of heating is highly effective and versatile.

What Is So Different About Radiant Heating

The main way that Radiant heating differs from conventional heating systems is with respect to heat circulation. With conventional heating systems, the hot air travels through ducts — then registers to deliver warmth. Frequently, this causes heat to be unevenly distributed in your property, because of hot air gathering close the ceiling – instead of inside the room. You have probably noticed that some rooms in your property are warm sometimes, while others are extremely cold. This is a big drawback of a conventional heating system. Typically, these systems distribute air erratically throughout your property.

In contrast, Radiant heating warms up a room from the ground level, which allows heat to be distributed more evenly. Everyone knows that heat rises, and warmth from the floor boards rises to heat up a whole room. In addition, the floor heating will warm anything in the vicinity, like your loved ones. Radiant heating is a bit like sunshine, in that it warms up objects and people in rooms somewhat. This enables warmth to travel to where it is required, instead of lingering on the ceiling.

So far, we have covered the reasons why Radiant heating might be regarded as superior to conventional heating systems. Next, let’s look some further advantages that Radiant heating offers. One key advantage of this residential heating method is that it reduces your energy bills and saves you cash. It achieves this with zone heating strategies, and by retaining heat naturally to warm your property whenever you require it.

Let us begin by evaluating the zone heating strategy that could save you cash on your energy bills. Radiant heating distributes heat in an even manner, where house occupants are situated. As a result, you are able to reduce the warmth in empty rooms, such as basements, bathrooms or a study – if they are not in use. The settings for zone controls enable you to select the preferred temperature in every room. In the end, this allows you to cut costs by keeping those empty rooms at a colder temperature. This benefits the environment and your bank account alike. It is obvious that radiant heating is a more efficient solution for energy provision, because it keeps heat exactly where you require it!

How Radiant Heating Saves Money

A further reason why Radiant heating saves you cash is because of its energy efficient nature. It harnesses the natural heat retaining ability of water to warm your property without consuming too much energy. It can keep rooms warm using a smaller amount of energy than a conventional heating system. Moreover, lots of people find that lower thermostat settings are more comfortable with Radiant heating, in contrast to conventional heating systems. As a result, you will save cash by consuming less energy with a lower setting on your thermostat. As well as using less energy, you do not need as much energy to stay comfortable. Therefore, your property will remain warm for an affordable price.

You can enhance your living space with Radiant heating as well. It can eliminate airborne dirt/dust and enhance the quality of air in your home. This kind of home heating method is ideal for anyone who suffers from allergies. The reason for this is that lots of systems based on forced air just send warm air through dirty, dusty vents. Often, the consequence of this is that the dirt and dust is projected into the air of your living space, further exacerbating allergies. Allergy sufferers will appreciate Radiant heating, because it does not heat homes using blown air. The property will still make you feel cozy and warm, without aggravating your allergies. With no vents circulating dirt and dust, only healthy, clean air will remain. Heating of this kind is vital for airborne allergy sufferers.

You might think that the above list of advantages of Radiant heating systems is exhaustive, however, there are several other benefits that you might want to take into account. Radiant heating does not simply eradicate cool drafts in your property, but audible fans too, along with the requirement for air ducts or a furnace. Because the system is concealed below your floors, you do not have to mess around with floor vents anymore. Each time you need to move your sofa slightly to the left to avoid a heating vent, remember the benefits that radiant heating offers. A system of this kind can help you considerably, even in smaller, less obvious ways. It does not simply eradicate cool drafts in your property, but also audible fans and the requirement for air ducts or a furnace.

Having read all of this information, do you think that Radiant heating is something that would add value to your life? If so, you might wish to think about contacting a professional. He or she will help you decide whether this kind of heating system will suit your property. You can also ask questions if you are still confused about anything. If you are tired of cool drafts, uneven heat and expensive energy bills, it might be time to change things up. Give serious consideration as to whether Radiant heating is the best option for your property.
