Sebagai negara tropis Indonesia telah mempunyai udara yang cenderung panas dan gerah. Untuk itu tak sedikit rumah-rumah modern sekarang yang telah dilengkapi dengan penyejuk udara atau Sparepart AC.

Namun seiring dengan usia pemakaian, sering terjadi Sparepart AC anda menjadi kurang dingin bahkan tak dingin sama sekali. Apa penyebabnya ?

1. Sparepart AC yang kotor, filter di unit AC yang kotor dapat menyebabkan terhalangnya peredaran udara dingin yang dibuat dari evaburator. Maka kerjakan minimal satu bulan sekali guna untuk membersihkan sisi AC itu supaya penyerapan udara dingin dapat makin optimal.

2. Bagian evaburator (evab) kotor, biarpun pada sparepart AC sudah dilengkapi dengan filter, akan tetapi debu yang halus sebagian tak tersaring filter itu, dengan begitu bakal masuk serta melekat pada area evaburator dimana lama-lama bakal penuh serta  bakal menghambat penyerapan udara dingin yang dibuat evaburator. Guna untuk menangkal penumpukan debu kerjakan pencucian area evaburator minimal tiga bulan sekali. Pada pembersihan area evab sebaiknya memakai layanan dari penyedia servis yang anda percaya. Sebab bila pencucian dikerjakan oleh seseorang yang tidak benar-benar mengerti tentang AC mungkin ketika pencucian, modul PCB bisa terpapar air, dimana pastinya menyebabkan korslet ketika dihidupkan. Sekaligus jugs dapat menyebabkan kerusakan di suku cadang lainnya.

3. Gas freon sedikit. Tekanan freon yang menurun dapat menyebabkan pencapaian temperatur dingin bakal membutuhkan tempo yang lumayan lama, dengan begitu kerja kompresor juga turut lama serta tiada waktu standby, serta yang bakal ada kompresor menjadi demikian panas juga bakal membuat pendek usia kompresor itu. Pada yang satu ini tidak boleh dikerjakan sendiri apabila anda tidak paham mengenai metode pengisian freon maupun berapa besar yang mesti diisikan. Sebab pengisian freon mesti dicocokkan pada power mesinnya

4. Kondensor kotor, kondensor alias lang cenderung dikenal pada unit outdoor sparepart AC atau disebut juga blower ini pun mesti terpelihara kebersihannya. Sebab ketika AC hidup, unit AC bakal mengalami panas di kondensornya, serta panas itu dibuang lewat terdapatnya  kipas yang terdapat pada sparepart AC itu. Serta jika prosedur pembuangan udara tidak mulus atau optimal, panas kondensor juga bakal terlalu tinggi, sehingga AC menjadi kurang dingin. Juga yang cenderung merepotkan jika mengabaikan kondensor kotor, lama-lama kompresor pun bakal mendapatkan panas berlebihan serta bakal overload. Bila dibiarkan maka kerja kompresor bakal melemah serta bakal membuat pendek usia kompresor. Oh ya jika kondensor terlampau kotor pun menyebabkan kerja kompresor menjadi berat serta penggunaan listrik pun  bakal meningkat alias bertambah, maupun juga yang dikatakan ampere naik melampaui standar wajarnya

 

PENYEBAB AC TIDAK DINGIN

Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.

The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.

In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.

Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.

Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.

The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.

In 2014, the technology was made available for the first time outside the laboratory.

“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”

Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.

The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.

“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.

The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.

Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.

Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.

At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.

“That was the Eureka moment,” Mr. Rolfs said.

In 1890, a girl in Edison’s laboratory had recited:

There was a little girl,

And she had a little curl

Audio

Right in the middle of her forehead.

When she was good,

She was very, very good.

But when she was bad, she was horrid.

Recently, the conservation center turned up another surprise.

In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.

Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.

“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.

The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.
