Inverter air conditioners are a great installation because they are energy efficient and they lower your electric bills. This technology uses a system that does not consume as much energy as a regular air conditioner. It saves energy and does not put holes in your pocket because of the cheaper electric bills.

Some people might think that buying an inverter air conditioner only makes them spend more money because it is more expensive than the regular kind. Although it is true that you have to spend more money initially when you buy it, the unit will pay for itself as time goes by because of the amount of savings that you get from your lowered electric bill. This is very practical especially if you are going to use the inverter air conditioner for a long time and if you do not have any plans of moving to another place.

This technology is also quieter than ordinary air conditioning units. You can install it in the nursery and your baby will still be sleeping peacefully when you turn it on. These are just some of the benefits of inverter air conditioner.

It is also important that you know some tips for choosing the right Inverter air conditioner for your home use.

Inverter Air Conditioner Tips

• First, you have to consider your room’s size. Large rooms require bigger units while small rooms require smaller units. This is also a great energy saving tip.
• You should also choose something that has both the cooling and dehumidifying feature. It is not enough that the unit can make the temperature cool. it is also important that it can keep the room dehumidified.
• You should also choose a good brand like Daikin or Fujitsu inverter. Daikin air conditioners and Fujitsu air conditioning units are great brands that you can depend on.

When it comes to the energy efficiency of your air conditioning unit, you just have to consult the stars.  No, it’s not a matter of astrology.  The product markings that indicate a product’s energy efficiency make use of stars.  To find out whether the air conditioning unit that you would like to purchase is energy efficient or not, just look at the blue strip containing stars.  You will find that an inverter air conditioning with the most number of stars is the most energy efficient.  Some efficiency ratings, however, are done based on an air conditioner running at full load.  Unfortunately, inverter air conditioners do not do well in this scenario.

Inverter Air Conditioners – Energy Efficiency

The best performance and the most energy efficient run of an inverter air conditioner is attained at partial loads.  Small homes typically run on partial load, making inverter air conditioners just ideal for their cooling needs.

As you scout around looking for options in inverter air conditioners, it is important for you to know what size of unit you need for your room or home.  More aptly, the cooling capacity of the air conditioning unit you choose should be just right for your room.  Even with more stars in energy efficiency, any unit that does not match the size of your room is not likely to run efficiently at all.  Getting an air conditioning unit that has a low capacity for a large family room could overwork the air conditioner and cause it to stop working.  When this happens to a conventional air conditioner, a little water sprayed at the metal coil at the back of the compressor is often advised.  In an inverter air conditioner, this is really not likely to happen.  At worse, your unit will work on overdrive and cause your electric bill to shoot up.  Under normal conditions, your inverter air conditioner should save you about as much as 30% from your electric bill.

Air conditioning is a process that provides clean air to any given area at the proper temperature and humidity. The term generally describes a refrigeration system created to cool the air inside a particular space. When heat is removed, the system also takes away moisture, further boosting comfort. Auxiliary filters may be used to remove pollutants from the air. Air conditioning needed for a building can be provided by a single, central air conditioners. Another common type is the self-contained room conditioner that fits into a window.

The First Air Conditioners

Credit for the first practical conditioning system is generally given to American inventor Willis Carrier, who designed a mechanical air conditioner in 1911 and began manufacturing conditioners in 1915.

The primary element of an air conditioners is their part called the refrigerant, which is oftentimes a fluorocarbon, flowing throughout the system and becoming a liquid and giving off heat when compressed. It then becomes a gas, working to absorb heat when the pressure is reduced. The processes that work for the evaporation and compression of the refrigerant part can be categorized into two areas: a fan, cooling coil, and air filter on the room side and a compressor, fan found, and condenser coil outside of the window.

Warm room air is drawn through the filter, blown over the cooling coil containing the refrigerant fluid, so that it is cooled, and then passed through a grille back into the area or room. In the compressor, the refrigerant gas from the cooling coil is further heated by compression. In the condenser coil it gives up heat and becomes a liquid, which is circulated back to the coils. A thermostat then regulates the compressor motor to regulate the temperature in the room.

Central Air Conditioners

Houses may actually be centrally air conditioned, but only if they somehow possess forced-air heating systems. These make use of a blower fan and ducts to distribute heated air during wintertime. During the summertime, said ducts can be utilized in order to bring cooled air. Large buildings may have cooling units in which a fresh-air intake mixes fresh outside air with inside air. This mixture is filtered and then cooled by passing it over the included coils of a rather big cooling unit. In regions where the air is dry, moisture is added. Finally, cooled air passes into the interior of the building.

Choose the right air conditioners for you home.

Daikin Air Conditioners

Daikin enjoys a positive reputation in the market. An example of the Daikin air conditioners is the Ururu Sarara series. It is a wall-mounted, split system air conditioners for residential use. It has the following features: Ururu humidifying operation, Sarara drying operation, fresh air supply ventilation and energy savings. In short, the Daikin Ururu Sarara series bas both humidifying and drying functions in one package, and works to normalize the indoor humidity level. It also has an air purifying unit that removes airborne pollutants and allergens which can be dangerous to one’s health. Aside from that, the Daikin’s Ururu Sarara series guarantees low energy consumption.

Mitsubishi air conditioners

Mitsubishi air conditioners, on the other hand, boast of the MEQ (Mitsubishi Electric Equality). The air conditioners also provide clean air through state-of-the-art air purification and deodorization filters. These eliminate airborne impurities and bad odor. Also, Mitsubishi air conditioners are designed to distribute temperature optimally and to operate without any unwholesome noise. Mitsubishi also guarantees cost-efficient performance and energy savings. Air Conditioning technologies provide high performance and reliability but on low power consumption. Lastly, the MEQ guarantees durability and long operational life; because there are some air conditioner that do not last after long periods of usage.

Fujitsu Air Conditioning

Fujitsu, another industrial giant, also makes well-performing air conditioners. An example of Fujitsu air conditioning is the Fujitsu AST30LBAJ. It is a split-type system, which is designed to cool the room temperature faster. However, this air conditioner also has features like those of the others, such as air filter, dehumidifier and cost-efficient performance.

Air conditioners are no doubt important home appliances in this day and age of modernization. The benefits air conditioning units provide outweigh the usually higher bills – cool, clean and fresh air and normal humidity level. When choosing what brand to buy, customers should critically compare each of them.

Window Air Conditioners

A common type of air conditioner is the window type. It is basically a single box that is fitted in a window sill or in a makeshift slot in the wall of the room. This is usually found in most residential homes. Window type air conditioners have all of its parts (condenser, compressor, expansion valve or coil, cooling coil and evaporator) enclosed inside a single box. All kinds of residential houses will go well with this type of air con.

Split System Air Conditioners

Second, the split system air conditioner is unlike the window-type. Instead of all parts in a single box, this type has an indoor unit (which has the cooling fan and the evaporator) and an outdoor unit (compressor, condenser and expansion valve). One won’t have cut a hole in a wall in install a split unit. And because of its design, these types of air conditioners is more preferred for its simple looks that can blend in with any room décor. It can also be use to cool one or two rooms. The split system air conditioner is also okay with all kinds of residential homes.

Commercial Air Conditioners

Commercial and industrial buildings, however, need larger air conditioners to cool the larger spaces. The types of air conditioners for this setting are the packaged air conditioners and the central air conditioning system.

The packaged air conditioners have two optional settings. In the first one, all the parts of an air con are enclosed in a single outdoor unit, and then the cooled air is flown through the ducts located in the rooms. In the second arrangement, the condenser and compressor are housed in a single unit, and then the compressed gas are passed through multiple units (with the expansion valve and cooling coil) located in the rooms. This is basically like the split-type air conditioners, but designed to cool larger, multiple spaces.

The central air conditioning system, meanwhile, uses a huge compressor that can produce tons of cooled air.

Daikin Air Conditioners

For such air conditioning needs, there’s Daikin. It is a Japan-based multinational corporation, specializing in and developing chemical, electronics and industrial technologies. The company however is originally a chemical corporation. Daikin has eight industrial and management divisions: Air Conditioners, Chemicals, Transportation & Refrigeration Systems, Semiconductors, Hydraulic Fluids, Electronics, Defense and After Sales. It is worth noting that the company manufactured Japan’s first fully-assembled air conditioner in 1951. And speaking of air conditioning, Daikin evenly competes with other industrial giants such as Mitsubishi, Fujitsu, etc. It offers air conditioners for home, commercial and industrial uses. The following is an overview of one of Daikin air conditioners, the Ururu Sarara series.

Air Conditioners – Ururu Sarara Series

The Ururu Sarara series is a wall-mounted type of air conditioner for residential use. It is a split-type that conditions the air of a single room. It is white-colored and has a long rectangle shape. Daikin’s Ururu Sarara boasts of having both drying as well as dehumidifying functions, together with fresh air supply ventilation. Whether it is in hot or cold climate, these air conditioners provides the best comfortable indoor temperature. Daikin has thrown in the following features to Ururu Sarara: fresh air supply ventilation Ururu humidifying operation, Sarara drying operation, and energy savings.

The Ururu humidifying operation is an ingenious method, because it does not use any water supply. Instead, it collects the moisture from air outdoors in order to normalize the humidity level indoors. Even in dry weather, the Ururu Sarara series prevents the air from getting too humid. Meanwhile, the Sarara drying operation removes the right amount of water vapors from the air, without affecting the temperature. For the fresh air supply ventilation, the Ururu Sarara series’ Flash unit does the job. It purifies the air and eliminates pollen, dust mites as well as other allergens.  Daikin air conditioners also guarantees an energy-saving operation.

What are Air Conditioners?

The most basic information about air conditioners is that air conditioners are appliances or mechanisms which function to bring us comfort by keeping the space where we rest or do things cool and not too humid or too dry.  So you find them in  cars, bedrooms, living rooms, gyms, offices, shopping malls and the like.   They are just everywhere nowadays.

What Air Conditioners do?

It is also useful to know what air conditioners actually do.  What an air conditioner does is basically keep a given space at a lower temperature than the outside.  Now that means taking heat from the space and moving it to the surroundings.  At the same time, it dehumidifies or removes moisture from the air.  This is because as air cools, some of the water vapour in it condenses.  This is the reason why some water drips from your car or from your window-type air conditioner.

Air Conditioners – How do they do it?

All air conditioners have four main basic components.  The part which extracts heat from the space to be cooled is the evaporator, the first component.  Here, a refrigerant changes from liquid to vapour.  In the process, it takes in heat.  The vapour is then compressed by a compressor, the second part,  where it is pressurized to make it condense back to liquid.  This occurs in the third component which is the condenser.  Here, it gives off heat, which is discarded to the environment outside the space to be called.  The refrigerant is then passed on to an expansion valve, the fourth part, where pressure is reduced before the refrigerant is returned to the evaporator, completing the cycle. You may want to know that this cycle is also what refrigerators do and so more properly it is called a refrigeration cycle.

So what does this information about air conditioners have to do with buying one?

Well, first of all, it should be obvious that the bigger the space you want to cool, the more heat you will need to remove from it.  This is called the cooling load and is often given in terms of horsepower or kilojoules, depending on whether your country uses the English or the metric system of units.

You also found that in this case heat is moved from a cool place to a hot place.  That’s against the natural flow of heat and, therefore, requires work.   In practice, you also need power to run a fan to circulate air and improve heat transfer.  All this power costs money so this is another thing you need to know.

You know that we will be using air conditioners continuously and for a long time.  So you should also be concerned about their efficiency and maintenance.  You want an air conditioner that will allow you to save — something that is intelligent enough to minimize power consumption.  Because air conditioners have many parts, they require maintenance.  Usually, it is the compressor that needs repair.  Often, it is a tube that leaks refrigerant.  These could cost money in the long run.

So the above information should give you a good idea about air conditioning units and should help you choose the correct system.  There are other details to consider but what you learned here are the basic and the most important.

Main Types of Air Conditioners

We may group air conditioners into arbitrary “types” which are characterized by installation and principle of operation.

• Split System.  This is so called because it “splits” the air conditioners into two.  One part, the cooling part lies outside the wall, which is advantageous because this part is also the noisy component of the system.  The split system is the most commonly known.  It may or may not require a ducting system and is used in most homes.  Ductless split systems are most efficient for use in rooms with open floor plans.
• Single-Package.  As its name suggests, this type contains all its components in one package which is usually installed in a roof.  This type of air conditioner is commonly used in industrial facilities.
• Portable Air Conditioners.  This type of air conditioning has a number of advantages.  First, it can be moved easily on wheels to provide cooling to a small space. In addition, it does not require creating a hole in your wall or ruining the beauty of a window. It is also very economical.  Downsides include having to open a window to let out condensate and noise.
• Evaporative Air Conditioners.  This type provides cooling by making air pass through water-logged pads.  As the water evaporates, it absorbs heat from the passing air, lowering its temperature.  The system works well when the air is dry but is not efficient in humid places.

Comparison of Non-Inverter and Inverter Split Systems Air Conditioners

One issue about air conditioners, no matter the type, is high energy consumption.  To reduce this, manufacturers are now using the so-called inverter technology.  In this section, we try to comparing the difference between split systems and inverters.

With the non-inverter split air conditioners, the compressor almost immediately goes to its full capacity upon switch-on.  Once the required temperature it turns off. It turns on again when the temperature rises.   As a result, there is an on-off cycle which results in peak voltages and wide fluctuations of temperature.  Because the compressor turns on and off repeatedly, a lot of power is used up.  In addition, the system contributes to peak loads.

On the other hand, the inverter split air conditioner uses a microprocessor-based intelligent sensor to check how conditions (temperature) are changing.  This relays the information to an “intelligent” compressor.  Unlike its conventional counterpart, this compressor is able to vary its rpm (revolution per minute) depending on the need for change.  Instead of turning off, it merely reduces its operation.  As a result, split systems that make use of inverter technology have the following advantages:

•    Both startup time and the time to reach temperature required for comfort is reduced by 1/3.
•    Power consumption is reduced by 30%.
•    There is no cycling of the compressor, and hence, voltage peaks.
•    Temperature fluctuations are minimized.
•    Quieter operation because of reduced rpm.

In conclusion, when we compare the split system and  Inverter air conditioners we find the inverter-based models to be more energy-efficient and closer to the green technology required by more environment-conscious consumers.  It is also clear that the advantages of this technology are not limited to split type systems.

The Climate and Air Conditioners

Australia is  semi-arid, being 40% desert and this is one big reason why you need air conditioners in Australia.    In terms of rainfall, it is next only to Antarctica in dryness.

However, climate does vary from region to region.  Generally speaking, the southeast and southwest regions have a temperate climate, while the northern part is tropical.

• The southeastern zone stretches along the coast from Ceduna in the south to Forster in New South Wales.  The climate here is known for warm summers and mild winters. Temperatures average 20°C annually and show few extremes.  Rainfall is also evenly distributed over the seasons but is usually heavier between January and June.
• In the Deserts of Australia, in the central semi-arid region, temperatures range from 18°C to 23°C in the winter and from 32°C to 40°C in the summer.  Rainfall is low.
• In the northern part of the country, the climate is tropical and very wet.  Relative humidity can average 30 percent during the dry season and 70 percent during the wet season.  Temperature has an average maximum between 30°C and 33°C and can fall to 14°C in the coolest months (June and July).

What Air Conditioners We Need to be Comfortable

Temperature and humidity may vary from place to place and from season to season, but our requirement for comfort remains nearly constant.  This is the rate at which we are able to cool ourselves by means of evaporation of sweat from our skin.

This is not as straightforward as it might seem.  It is a subjective feeling that also depends both on the temperature and the rate of evaporation of sweat from our skin.  Now this rate is affected by humidity.  As humidity increases, it decreases and we feel warmer than a thermometer would otherwise indicate.    For example, even if the air temperature is actually 24°C we feel like it is 21°C when the relative humidity is zero percent.  On the other hand, we feel as if it is 27°C when the relative humidity is 100 percent!

So comfort is defined by both humidity and temperature.  Experts found that, in the summer, when the relative humidity is 30 percent, the comfortable temperature range for a general-purpose space is said to be 24°C to 29°C.  If the relative humidity is 60 percent, the recommended range is  23°C to 26°C.  In the winter, the temperature range is 21°C to 26°C at a relative humidity of 30 percent, and 20°C to 24°C at 60 percent relative humidity.  Experts recommend different humidity and temperature levels for different spaces.

So your personal comfort and safety is the other reason you need air conditioners in Australia

What Air Conditioners Can Give Us

So the main reason Why you need an air conditioner in Australia is the need to create an indoor climate that is more comfortable, healthier and safer than outdoor conditions.  In the context of the variable and sometimes extreme Australian climate, this calls for a more constant temperature or humidity.

An inverter air conditioner is also quieter than its ordinary counterpart. You will not hear loud whirring sounds that are common when a regular air conditioning unit is running. You can turn it on even while your baby is sleeping. It is virtually noiseless which makes it the perfect cooling device in a bedroom or anywhere where silence is required.

Inverter air conditioners can be quite expensive. This high cost is what usually makes people not buy an inverter air conditioner for themselves. However, you should keep in mind that you will be saving money every month because of the reduced utility bill. This will save you more money in the long run, even if you have to pay a huge amount for the unit initially.

Two of the leading inverter brands are Fujitsu and Daikin air conditioning. These two bands equipment are very similar but Fujitsu Inverters are generally slightly cheaper.

As with standard air conditioning systems Inverter air conditioners require regular maintenance like checking the condenser for debris. If the condenser is blocked, the air will not flow properly, which makes your air conditioner inefficient. This can also damage your unit easily. Remove any debris and regularly wipe dirt and dust off the surface.
