Understanding the Energy Efficiency/Star Ratings (EER) of the AC

Understanding the Energy Efficiency/Star Ratings of the AC’s available in the market is important because an inefficient AC can be quite expensive to run, and nowadays all firms provide this kind of data on their AC/Refrigerator models.

Here is a link to a document on the website of Bureau of Energy Efficiency which lists the star ratings of many AC models available in India:
The higher the star rating, the better the AC.

Overview of EER and Star Ratings:

AC’s are rated in tonnage for their cooling power. But a tonnage means about 12,000 Btu/hr of cooling capacity. Therefore, 1.5 tons AC corresponds to 18,000 BTU/h. Moreover, a tonnage equals 3.5 kW approx.

Now, the tonnage tells about the output of the AC, i.e., its cooling capacity. But to find out its efficiency, we need find out its power consumption as well. Assuming it to be watts, the EER or Energy Efficiency Ratio is defined as:

The ratio arrived at, by dividing the Cooling Capacity of the Air conditioner, by the electrical power input expressed in Watts. The formula is:

EER = (Cooling capacity in Watts)/Electrical consumption in Watts

The higher the EER, the better the efficiency.

The Bureau of Energy Efficiency arrives at Star Ratings after testing the various models of AC’s available in India. Following is the table used for certifying ACs with star ratings:

Although these limits have been moved up this year (by .2 EER each) the document specified earlier seems to be following this table only. This table, and the rating and labeling is explained in the doc available at http://bee-india.nic.in/Label-launch/Schedule3-RAC.pdf

Let’s take a typical example: a 1.5 ton AC = 5.25 kW = 4.8 kW at 90% cooling efficiency factor having a power consumption of 1900 Watts has an EER of 4800/1900 = 2.53 approx. and would have a star rating of 2 according to the table above.

If compared with a non star rated AC, having an EER of 2.2 for example, and hence an energy consumption of 4800/2.2 = 2182 Watts approx. the difference in electrical power consumption comes out to be about 282 watts (2182-1900). Assuming usage of 8 hours per day for 4 months per year, the total energy consumption comes out to be 8 hrs x 120 days x 282 watts = 270720 Watt hours or 270.72 kW-Hr.

Multiply with rate of electrical unit (say for example it falls in 101-200 units a month range, taking average of Rs. 2.5 per unit), the difference in expenditure comes out to be about 270.72 x 2.5 = Rs. 676.80. ( 1 unit = 1 kw-Hr)

Now, one would have to calculate these savings by putting in the exact values for the AC cooling capacity, the power consumption and the usage. The document specified earlier lists several ACs and their EER and Star Ratings which can be used for this purpose.

After this, one would need to decide if the extra capital expenditure initially, for a higher star rated AC, is justified by the savings in power consumption over the lifetime of the AC. (Playing the devil’s advocate here, because there is also a reason for buying higher efficient ACs regardless of one’s actual usage as it is better for the environment.)

Hope this data helps us in purchasing the right AC.

TOI Article : How Agra got the Taj


"Wahan toh road bahut kharab hai", was our guide's first reaction, when informed about the intention to visit Mumtaz Mahal's grave, or kabr . It is early morning in Burhanpur, a small town in southern Madhya Pradesh, near the Maharashtra border, and despite the threat of the kharab road, we set out for the kabr . Not many would have heard of Burhanpur today, but it occupied a prominent place in the empire during Mughal times, since it was a strategic point from which to control the Deccan region. It was here that Shah Jahan spent a considerable number of years as governor of the Deccan region, before his ascension to the throne. And it was in Burhanpur, two years after he became the emperor — on June 17, 1631, to be precise — that his beloved wife Mumtaz Mahal passed away, while giving birth to their 14th child. A grief-stricken emperor had her laid to rest near the banks of the Tapti river and a monument was built, where her remains were kept. Simultaneously, work also started on a grand mausoleum near the kabr . Shah Jahan wanted it to be a monument of unparalleled beauty, conceptualised in white marble, whose reflection in the Tapti river would increase its beauty manifold. Yes, the Taj Mahal was initially planned to be built at Burhanpur. However, destiny had other plans. Today, the vast stretches of open land on the banks of the Tapti river, near Mumtaz Mahal's kabr in Burhanpur, stand mute testimony to what could have been.

By the time we reach the kabr , located almost 10 km away from the town of Burhanpur, the sun is shining brightly overhead. A few kilometres away from our destinition, the road gives way to a wobbly dust track that finally leads to a monument, now largely a ruin. A signboard next to it proclaims it as Begum Mumtaz Mahal ki kabr and claims that it is ostensibly protected by the state archaeology department. Two boys, playing cricket nearby, offer to show us around the ruins. We go down a flight of stairs to a small chamber, where Mumtaz Mahal's body was presumably buried. Debris and rubble now covers the floor. Sometime back, we are informed, the ground here was levelled. So, any sign of a kabr has now disappeared. The ruins of a masjid, built in her memory, lie nearby. This state of disrepair is a little ironical because almost 400 years ago — during Shah Jahan's time — this complex would perhaps have been one of the most important buildings of the Mughal empire. One can almost visualise the scenes that must have unfolded here. History books tell us that Shah Jahan was devotedly attached to Mumtaz Mahal, to a degree rarely seen in polygamous households, especially royal ones. Her death, therefore, had a profound impact on him, with one account suggesting that because of the shock, his hair turned completely grey. His grief found other expressions too. Every Friday, it is believed, the emperor would come to the kabr and light a lamp in his wife's memory, even as maulvis recited verses from the Quran and pandits chanted shlokas near the burial chamber. In fact, the alcoves where the lamps were lit — known as chiraagdaan — can still be seen in the wall around the complex. Much of the surrounding landscape has also not changed, with the Tapti river flowing placidly nearby, as it would have, during those times. No wonder then, that Shah Jahan wanted to have his Taj built here. Three things, however, prevented this from happening, says Vinit Sharma, head of the history department of Burhanpur's Seva Sadan college. "First, there were logistical problems in transporting marble from the quarries in Makrana in Rajasthan to Burhanpur. Then, when the builders evaluated the site, they found that the black soil along the Tapti could not support the weight of a structure of the magnitude that they were planning. They advised Shah Jahan to shift the mausoleum away from the river, but he was adamant that it should be built along the river, so that he could see its reflection. Therefore, the hunt began for a better location and finally, the project was shifted to Agra. Being the capital of the empire, it was felt to be a more practical choice, since the emperor could then visit the mausoleum more frequently. Further, its proximity to marble quarries and the presence of better soil along the Yamuna also went in its favour," says Sharma. While the location of the mausoleum was being decided, Mumtaz Mahal's body remained in the kabr at Burhanpur. It is generally believed that it was kept here for six months and a temporary burial, known as amanat was performed, although there is no clear account of whether the body was preserved. However, according to Armanul Haq of Jamia Hamdard, who published a research on this subject some years ago, Mumtaz Mahal's body would have been preserved according to Unani techniques. In his research report, Haq says that the body was probably kept in an air-tight box, filled with herbs like camphor, acacia, sandalwood, ash etc, that created a vacuum and prevented it from decaying. Since Islam prohibits cutting a body after death, these herbs were packed tightly in layers around the body, points out Haq. However, according to Sharma, it is highly unlikely that the body could have been preserved for long. By the time it would have been taken to Agra, only the skeleton would have remained, he says. Nevertheless, it is fascinating to know that Mumtaz Mahal's body was buried at three different places at various times. According to KK Muhammad, superintending archaeologist of Bhopal circle, first the body was kept at the royal hunting palace, the ahukhana, located near the kabr in Burhanpur. Here, the ceremony of takfeen or wrapping it in a kafan was performed, before it was taken to the kabr , where it was interred for six months. It was then taken to Agra where it was buried for a few years, while the Taj Mahal was being built, before finally being shifted to its ultimate resting place in the monument's basement. The Taj, of course, has been associated with Mumtaz Mahal for centuries and has got its due recognition. But perhaps, it's time the other monuments that have played their part in this saga — like the kabr and ahukhana in Burhanpur — also get their due. For, Agra may have got the Taj, but the story behind it, still reverbrates in these monuments in Burhanpur.

Signinficance of position of Moles on Women's Face




Classic Chinese Face Reading : Moles on Women's Face

Moles on your face are like stones in your house. When appearing in the living room (your forehead and cheeks), they mess the look of your household; when showing up in the corridors (your nose and mouth), they block the passage. But if they emerge in the undergrowth (your hair) or below a rock (you torso) in your backyard (a private place away from public view), they could form a little wonder of the landscape (your fortunes-cape).
