5 star rated air conditioner

In recent years the government of India has made it mandatory for all electrical appliances to have a star rating. This rating basically determines the energy efficiency of an electronic product like a refrigerator, air conditioner, microwave oven, etc. The Bureau of Energy Efficiency (BEE) is the statutory body under the Union Ministry of Power that gives these ratings. Thus, if you are looking for any AC unit for your home or office space you can now buy a 5 star rated air conditioner instead of anything with a lower rating. There are quite a few benefits in going for a 5 star rated AC unit.

First of all, even though if you survey the market for air conditioners you are bound to come across units that are being sold for a lot cheaper, 5 star rated units have the advantage in the long run. How? Well, while other units may be cheaper to buy, they make up for the money in recurring electricity bills. They consume considerable more units of electricity as compared to ones that have higher ratings, especially 5 star units. On the other hand, 5 star AC units may be expensive, but they assure lower electrical consumption, which translates into affordable bills.

Star rated air conditioning units are more expensive as the manufacturers have to change the design parameters of the unit in order to increase its energy efficiency, which leads to an increase in the initial cost of the AC unit. This being said, very few of us realize that the initial cost of the unit contributes to just 11% of the total expense of owning an AC. It is all about the running. So, if you want the AC for mere show, it may be okay to consider a unit with very low rating, but if you do intend to use it as and when without giving much thought, the 5 star rated units may be ideal. Remember that you must keep in mind that the initial cost, maintenance cost and the running cost together determines whether the AC is right for your needs.

EER, which is the Energy Efficiency Ratio is the ratio between the cooling capacity of the unit and the power input. AC units with higher EER consume less power. These ratings are mentioned on all air conditioners these days, regardless of the manufacturing company. If you intend to use the AC several hours in a day, and are looking for something that will keep your electricity bills in check, go for a 5 star rated air conditioner. The good news is that there are plenty of good company options available on the market today. All you need to do is choose.

Types of air conditioners

Air conditioners are a must in every home and office nowadays, especially if you want to stay away from the outdoor dust, noise and pollution. Plus, it gives the home or office a sophisticated and rich look. The age of having fans all over the office has long gone. These days, you can find a wide range in air conditioners to suit almost any kind of set-up or budget. There are many types of air conditioners available on the market. All you need to do is figure out your requirements and choose the one that fits your bill. The ones that are most popular and worth checking out are window air conditioners, split air conditioners, central air conditioning systems, and portable air conditioners.

Window air conditioners were most preferred in houses and small office cabins. The window air conditioning system is ideal for rented or leased spaces as one cannot make constructional changes to the area. Most window units fit comfortably in window openings and provide sufficient cooling for one room, depending on the unit size as well as the area to be covered. In such units all the components such as expansion valve, evaporator, cooling coil, condenser, and compressor are all included in the single box, which means that they are much easier to install.

Portable air conditioners are the best for spot cooling. There are many families that have split air conditioners in the living room and bedrooms but prefer portable AC for kitchen or other areas where fixing an unmovable unit does not make sense. For example, if your home is small and you cannot find the place to install a window or split air conditioner, you can buy a portable AC for your bedroom. These units are known to be reliable and efficient, while also requiring very little space thanks to their small bodies.

Split air conditioners are by far the most popular type for small offices and homes these days. Made up of an outdoor unit comprised of the compressor, condenser and expansion valve, and an indoor unit with the evaporator and the cooling fan, this system is ideal for those who do not want to make any slots in the wall. Today, most companies in the air conditioning business make split AC units that are aesthetically good looking and add a beautiful touch to almost any décor. Another plus point is that you can buy a bigger system to cool large rooms or even multiple adjoined areas.

While central air conditioning systems are very rarely used in small houses, when talking about types of air conditioners this type cannot be forgotten. These systems are used for cooling of big commercial buildings, large houses, big offices, entire hotels, gyms, factories, movie theatres, etc. The large areas and entire floors or buildings are to be cooled, putting split systems no matter how large, can turn out to be very expensive in cost as well as in the long run. In such cases central air conditioners are perfect.

Facts about AC Drive

There was a time in manufacturing history of air conditioners when speed control from a singular motor was achieved through a series of large pulleys that would power the large flat belts. The various sizes and combinations of these sized pulleys and belts together decided the speeds. Being extremely inefficient and hazardous as the pulleys were open faced and exposed. Eventually smaller belt and pulley systems were invented and electric motors became compact and although the efficiency was still lagging behind. The problem was effectively solved with the invention of modern AC drives. These drives operate on the principle of controlling the frequency of the AC, which is sent to the motor. The adjustments on frequency also affect the voltage, while the amount of power delivered to the moving motor remains constant.

There are many ways of referring to AC drives in the industry. They may be called Inverters, Variable Speed Drives (VSD), Variable Frequency Drives (VFD) or Frequency Converters, as their primary function is to control the AC induction motor. A distinctive feature of AC drives is that by controlling the frequency delivered to the motor, they can monitor any adverse or overload conditions experienced by the unit due to things like equipment failure, electrical flouting and the like. In view of this fact, plenty of manufacturers these days are setting the AC drives to cease operation at any minor infraction that may cause harm to the motor. This saves manufacturers huge amounts in motor replacements. Some leading manufacturers even have intelligent drives that have programmable automation or motion controllers within the product to eliminate communication delays, improve performance, efficiency in motion application, save panel space by removing the need for external controls.

The chief reason for the demand of such drives is the energy consumption factor. It is estimated that such drives end up saving up to 20% more energy if installed and operated in an efficient way. These AC drives also play a key role to reduce carbon emissions into the environment, taking into consideration that the motors consume almost two thirds of electrical energy. Since energy efficiency, money saving and environmental conservation are three important aspects in buying electronic products, the significance of AC drives can be realized.

The need for buying a product with a high quality AC drive is very high nowadays, when the value of money is so high, thanks to the extreme inflation. In fact, a majority of smart buyers in the market ask for details and specifications of the product. Some of the frequently asked questions include inquiries about the AC drive and in turn the energy star ratings, efficiency of cooling, tonnage and size, product reputation, installation charges, product life cycle, etc.
