Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to the general art of automatic temperature and humidity regulation, and to the particular field of automatic temperature and humidity regulation which is remotely adjusted.
2. Discussion of the Related Art
Many people desire to adjust the temperature in their home to one level during the day and another level at night. Sometimes, people desire to adjust the temperature several times during the day. While this is a minor inconvenience for many people, it can be an onerous task for a disabled person. It may even be impossible for a bedridden person.
While the art contains several examples of remotely controlled thermostats, such presently existing systems are not amenable for use by the disabled.
Therefore, there is a need for a remotely controlled thermostat system that is amenable for use by a disabled person.
Nearly every thermostat, or thermostat system, displays temperature. This temperature display is used to identify present ambient temperature and as a guide to setting desired ambient temperature. While this is convenient for most people, a sight-impaired individual, or a person attempting to use and set the system at night or in the dark may find such displays nearly useless.
Therefore, there is a need for a remotely controlled thermostat system that is amenable for use by a sight-impaired person.
To be most commercially acceptable, any system should be amenable to retrofitting existing systems. This will enable someone to modify their existing system with only minor adjustments thereby making a modification of the existing system cost- and time-effective.
Therefore, there is a need for a remotely controlled thermostat system that is amenable for use by a sight-impaired person and which can be easily and quickly retro-fit to an existing system.

The device embodying the present invention is amendable to use by a sight-impaired individual because he or she can easily find the switches that need to be operated by finding the braille labels, and then can operate the switches and listen for the sounds to determine first what the present temperature is and then how much the temperature is increased or decreased. This can be used in the dark as well. The device is easily and quickly retro-fit to any existing thermostat by hard wiring so an existing system is quickly and easily modified as required.

Referring to the Figures, it can be understood that the present invention is embodied in a thermostat remote control system 10. System 10 can be used by a sight-impaired and/or bedridden person to adjust the ambient temperature in a room. System 10 comprises a thermostat unit 12 associated with a building climate control system 14 such as a heating and/or air conditioning system. The thermostat unit 12 includes a temperature sensor 16 that senses temperature of the building and generates temperature signals 18 associated with the temperature sensed by the temperature sensor 16. A building temperature control circuit 20 is electrically connected to the temperature sensor 16 to receive temperature signals 18 from the temperature sensor 16 and is connected to the building climate control system 14 by a lead line 22 to control building temperature in accordance with temperature signals 18 received from the temperature sensor 16 in response to temperature signals 18 received from the temperature sensor 16.
A hard-wired unit 30 includes a housing 32. A wall-mounting element 33 on the housing 32 is adapted to mount the housing 32 on a wall. Preferably, housing 32 is mounted on a wall adjacent to the thermostat unit 12. Hard-wired unit 30 also includes a power source 34 in the housing 32. Power source 34 can be a battery or the unit 30 can be wired to building power.
A first lead line 36 is electrically connected to the temperature sensor 16 of the thermostat unit 12 and a second lead line 38 is electrically connected to the building temperature control circuit 20 of thermostat unit 12. Unit 30 is thus hard-wired to the thermostat unit 12.
Unit 30 further includes a thermostat-monitoring circuit 40 that is electrically connected to first lead line 36 to be electrically connected to the temperature sensor 16 of the thermostat unit 12 to receive temperature signals 18 from the temperature sensor 16 of the thermostat-monitoring circuit 40. The thermostat-monitoring circuit 40 includes a temperature signal-generating circuit 42 which generates temperature-monitoring signals associated with the temperature signals 16 received by the monitoring circuit 40 from the thermostat temperature sensor 16 in response to the temperature signals 18 received from the thermostat temperature sensor 16.
A transmitter circuit 44 is electrically connected to the thermostat-monitoring circuit 40 to receive temperature-monitoring signals from the thermostat-monitoring circuit 40 and generate wireless temperature-monitoring signals, indicated in FIG. 4 as wireless signal 46, that are associated with the temperature-monitoring signals received by the transmitter circuit 44 from the thermostat-monitoring circuit 40 in response to the temperature-monitoring signals received from the thermostat-monitoring circuit 40.
A thermostat control circuit 50 is electrically connected to second lead line 38 and is also electrically connected via the second lead line to building temperature control circuit 20 of the thermostat unit 12 to control the building temperature via building temperature control circuit 20 of the thermostat unit 12. A receiver circuit 52 receives wireless signals, indicated in FIG. 4 as wireless signal 56, and is electrically connected to thermostat control circuit 50 and generates control signals associated with the wireless signals received by the receiver circuit 52 in response to the wireless signals received by the receiver circuit 52. The control signals are sent to the thermostat control circuit 50 of the hard-wired unit 30 and via the thermostat control circuit 50 of the hard-wired unit 30 to building temperature control circuit 20 of the thermostat unit 12 and via the building temperature control circuit 20 of the thermostat unit 12 to the building climate control system 14. The thermostat building temperature control circuit 20 is controlled in accordance with the wireless signals received by the receiver circuit 52 of the hard-wired unit 30.
A remote control unit 60 includes a housing 62 that can be shaped to comfortably fit into a user's hand, a power source 64, and a door 66 associated with the power source 64. Door 66 can include a logo or the like if desired or can include a braille label 68 to indicate that the power source 64 is located behind the door 66.
A display unit 70 is located on the housing 62 of the remote control unit 60 and can be an LED unit or the like. Display unit 70 can be backlit to assist someone in the dark, and can include a light 72 if suitable.
An on/off switch 74 is electrically connected to the power source 64 of the remote control unit 60 and has an “on” condition and an “off” condition. The switch 74 can be moved between the two conditions by pressing the switch 74. A braille label 78 is associated with the on/off switch 74 of the remote control unit 60 so a sight-impaired user can identify which switch is the on/off switch 74.
A temperature-increasing switch 80 is located on the housing 62 of the remote control unit 60, and a temperature-increasing signal-generating circuit 82 is electrically connected to the temperature-increasing switch 80 and to the power source 64 of the remote control unit 60. Circuit 82 generates temperature-increasing signals when the temperature-increasing switch 80 is activated, such as by pressing, and the on/off switch 74 is in an “on” condition.
A wireless signal-transmitting circuit 90 is electrically connected to the temperature-increasing signal-generating circuit 82 to receive temperature-increasing signals, such as signal 92 indicated in FIG. 4, from the temperature-increasing signal-generating circuit 82 and generates wireless temperature increase signals, such as wireless signal 56 indicated in FIG. 4, associated with the temperature-increasing signals received by the wireless signal-transmitting circuit 90 in response to temperature-increasing signals 92 received from the temperature-increasing signal-generating circuit 82. The wireless temperature increase signals are received by receiver circuit 52 of the hard-wired unit 30. The receiver circuit 52 of the hard-wired unit 30 generates a temperature increase control signal, indicated as signal 94 in FIG. 4, in response to the wireless temperature increase signal received from the transmitter circuit 90 of the remote unit 60.
A braille label 100 is associated with the temperature-increasing switch 80 on the housing 62 of the remote control unit 60.
A sound-generating circuit 102 is electrically connected to the power source 64 of the remote control unit 60 and is electrically connected to the temperature-increasing switch 80 via the on/off switch 74 to emit a sound-generating signal when the temperature-increasing switch 80 is activated and the on/off switch 74 is “on”.
A temperature-decreasing switch 110 is located on the housing of the remote control unit 60. A temperature-decreasing signal-generating circuit 112 is electrically connected to the temperature-decreasing switch 110 and to the power source 64 of the remote control unit 60 and generates temperature-decreasing signals, indicated in FIG. 4 as signals 114, when the temperature-decreasing switch 110 is activated and the on/off switch 74 is in an “on” condition.
The temperature-decreasing signal-generating circuit 112 is electrically connected to the wireless signal-transmitting circuit 90 so the wireless signal-transmitting circuit 90 receives temperature-decreasing signals 114 from the temperature-decreasing signal-generating circuit 112 and generates wireless temperature decrease signals, such as signal 56, associated with the temperature-decreasing signals 114 received from the temperature-decreasing signal-generating circuit 112 in response to temperature-decreasing signals 114 received from the temperature-decreasing signal-generating circuit 112. The wireless temperature decrease signals are received by receiver circuit 52 of the hard-wired unit 30. Receiver circuit 52 of the hard-wired unit 30 generates a temperature decrease control signal in response to the wireless temperature decrease signal received from the wireless transmitting circuit 90 of the remote unit 60.
A braille label 116 is associated with the temperature-decreasing switch 110 on the housing 62 of the remote control unit 60. A sound-generating circuit 118 is electrically connected to the power source 64 on the remote control unit 60 via the on/off switch 74 and is electrically connected to the temperature-decreasing switch 110 via the on/off switch 74 to emit a sound-generating signal when the temperature-decreasing switch 110 is activated and the on/off switch 74 is “on”.
An audio control element 120 is on the remote control unit 60, and is electrically connected to the sound-generating circuit 102 connected to the temperature-increasing switch 80 and to the sound-generating circuit 118 connected to the temperature-decreasing switch 110 to control the level of the sound-generating signals emitted by the sound-generating circuit 102 connected to the temperature-increasing switch 80 and by the sound-generating circuit 118 connected to the temperature-decreasing switch 110. A braille label 122 is located on the remote control unit 60 adjacent to the audio control element 120.
A sound-generating speaker 124 is on the remote control unit 60. Sound-generating speaker 124 is electrically connected via the audio control element 120 to the sound-generating circuit 102 connected to the temperature-increasing switch 80 and to the sound-generating circuit 118 connected to the temperature-decreasing switch 110 via the audio control element 120. The sound-generating speaker 124 generates a first audible signal 126 when the temperature-increasing switch 80 is activated and a second audible signal 128 when the temperature-decreasing switch 110 is activated. First audible signal 126 is different from second audible signal 128 so a sight-impaired user can distinguish whether the temperature is being increased or decreased.
The remote control unit 60 further includes a receiver circuit 130 which receives wireless signals, such as wireless signal 46, from transmitter circuit 44 of the hard-wired unit 30. The wireless signals 46 received by the receiver circuit 130 of the remote control unit 60 correspond to temperature readings of the temperature sensor 16 of the thermostat unit 12 and are generated by the transmitter circuit 44 of the hard-wired unit 30 in response to signals received by the transmitter circuit 44 of the hard-wired unit 30 from the temperature sensor 16 of the thermostat unit 12 via the thermostat-monitoring circuit 40 of the hard-wired unit 30.
A temperature display circuit 132 electrically connects display unit 70 of the remote control unit 60 to receiver circuit 130 of the remote control unit 60 to display visual signals on the display unit 70 which correspond to the wireless temperature-monitoring signals received by the receiver circuit 130 of the remote control unit 60 from the transmitter circuit 44 of the hard-wired unit 30 in response to the wireless temperature-monitoring signals received by the receiver circuit 130 of the remote control unit 60 from the transmitter circuit 44 of the hard-wired unit 30.
An audio circuit 140 is electrically connected to temperature display circuit 132 of the remote control unit 60 via display unit 70. Audio circuit 140 includes a sound generator 142 which generates audible signals which correspond to the wireless temperature-monitoring signals 46 received by the receiver circuit 130 of the remote control unit 60 from the transmitter circuit 44 of the hard-wired unit 30 in response to the wireless temperature-monitoring signals 46 received by the receiver circuit 130 of the remote control unit 60 from the transmitter circuit 44 of the hard-wired unit 30. For example, a first set of audio signals can be generated for the tens digits in the thermostat temperature sensor 16 and a second set of audio signals can be generated for the units digits in the thermostat temperature sensor 16. The audio signals associated with the readings in the thermostat temperature sensor 16 can be different from the audio signals associated with increasing or decreasing the temperature using the switches 80 and 110.
A supporting element 150 is positioned on the remote control unit 60. The supporting element 150 can include a rubber base so the remote control unit 60 is stable when it is left standing. The housing 62 can also be shaped to comfortably fit into a user's hand.
The thermostat remote control system 10 of the present invention can also include a lighting element 152 associated with audio control element 120 on the remote control unit 60. The lighting element 152 can be used by those who have some sight or those who use the remote control unit 60 in the dark.
It is understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangements of parts described and shown.

ac diagram dan sistem kerjanya

AC dan cara kerjanya...

AC/pendingin ruangan adalah singkatan dari air conditioning yang secara teknik artinya pengatur otomatis dari suhu, kelembapan dan arus udara di dalam bangun manapun; selain mengatur suhu, kelembapan dan arus udara, AC juga bisa mengatur bakteri, debu, dan juga gas-gas.

AC terdiri dari 3 bagian utama yaitu:
-Sebuah kompresor yang rapat.
-Sebuah kondensator.
-Sebuah evaporator dengan pipa kapiler yang mengontrol pendinginan.

Secara sederhana, prinsip kerja AC sama seperti prinsip kerja lotion/cologne. Ketika lotion/cologne tersebut dioleskan ke permukaan tubuh, cairan ini akan menguap dengan menyerap kalor; kalor yang diserap adalah kalor dari dalam tubuh. Sehingga pada saat menguap, lotion akan meninggalkan suhu , keadaan dingin di tempat lotion tersebut dioleskan.

Sistem Kerja AC
Sistem kerja AC secara umum dibagi dalam 2 macam; sistem yang pertama adalah AC sebagai pendingin ruang saja. Sedangkan sistem yang kedua adalah AC sebagai pendingin sekaligus pemanas ruangan.

1. AC bekerja sebagai pendingin ruangan.

Gambar1 – Skema kerja AC sebagai pendingin ruangan

Pertama kali bekerja, uap freon (warna kuning) yang berasal dari evaporator ditekan oleh kompresor menuju kondensator (warna biru). Pada kondensator karena bertekanan tinggi dan dilakukan pendinginan sehingga suhunya turun; pendinginan dilakukan dengan mengalirkan udara luar ke dalam kondensator dan mengeluarkannya kembali secara terus menerus dengan bantuan kondensator-fan uap freon(fluida dalam sistem perpipaan yang tertutup di dalam AC) mengalami kondensasi sehingga berubah menjadi cairan freon (warna merah). Untuk meningkatkan tekanan, sistem perpipaan mengecil dengan melewati pipa kapiler setelah terjadi kondensasi. Fluida bertekanan tinggi tersebut selanjutnya mengalami expansi secara mendadak dalam ruang evaporasi sehingga cairan freon berubah seketika menjadi uap. Dalam proses perubahan menjadi fase uapp ini, dibutuhkan energi Q sebesar m x lv (Q = m. l.v). Energi ini diperoleh dari lingkungan di sekitar evaporator, sehingga evaporator menjadi dingin.
Ruang evaporator yang dingin tersebut dimanfaatkan oleh manusia untuk mendingin kan ruangan. Prosesnya adalah: mengalirkan udara ruangan ke dalam evaporator dan mengeluarkannya kembali ke ruangan secara terus-menerus(siklus) dengan bantuan evaporator-fan sehingga ruangan menjadi dingin. Uap freon yang terbentuk tersebut (warna kuning) selanjutnya dialirkan ke kompresor untuk mengulangi langkah awal secara terus-menerus.

2. AC bekerja sebagai pendingin dan penghangat ruangan.

Gambar2 – Skema kerja AC sebagai pendingin dan penghangat ruangan

Prosesnya pendinginan ruangnnya sama dengan AC sebagai pendingin ruangan; untuk sistem penghangat ruangan, AC ini dilengkapi dengan alat heater elektrik pada ruang evaporator. Pada waktu menghangatkan ruangan, sistem pendingin ruangan dimatikan tetapi menghidupkan sistem penghangat ruangan. Sistem ini bekerja dengan cara heater elektrik yang ada pada ruang evaporator akan dilewati dengan udara dingin yang berasal dari ruangan dengan bantuan evaporator-fan sehingga udara menyerap panas yang dikeluarkan oleh heater, selanjutnya udara dikirim ke luar ruangan secara terus-menerus sehingga ruangan akan menjadi hangat.

Untuk mengontrol suhu ruangan, bisanya di dalam AC disediakan seperangkat alat yang terdiri dari termometer, yang disetel sesuai dengan suhu maximal dan minimal yang kita inginkan.

Secara sederhana cara kerja AC dapat digambarkan dalam blok diagram dan Ph Chart sebagai berikut;

Dalam Ph (Preasure enthalphy) Chart dapat digambarkan sebagai berikut:
AB = Proses Compresi
BC = Proses pengembunan dari gas ke cair. (terjadi di kondensor)
CD = Proses penurunan tekanan yaitu di expansion valve
DA = Proses pengambilan panas dari udara di sekitarnya oleh freon yang berupa gas(terjadi di evaporator)

Sewaktu compressor bekerja (proses AB), gas dimampatkan (temperatur dan tekanan naik) ke condensor.
Di sini udara yang ditiupkan ke condensor (proses BC), menyebabkan temperatur gas turun dan berubah menjadi cairan.
Melalui filter dryer (untuk menghisap moisture) liquid freon (freon cair) menuju expansion valve (proses CD) di mana cairan mengalami:
1. Penurunan tekanan
2. Pengubahan bentuk dari cair menjadi gas
Perubahan bentuk terjadi dengan menghisap panas (atau mengeluarkan dingin) dari / ke udara ke sekitarnya (proses DA). Dengan bantuan fan-evaporator, udara dialirkan ke kamar yang didinginkan.
Liquid yang tak sempat berubah menjadi gas ditampung di suction accumulator.

Demikian seterusnya proses terjadi berulang-ulang.

cinta telah pergi

Hari begitu cerah suasana tampak ramai di halaman sekolah.Ini adalah hari pertama ku jadi siswa baru di SMA vavorit yang selama ini aku ingin kan.
“mudah-mudahan saja hari ini akan lebih baik” bicara ku dlam hati
di saat aku berjalan sambil termenung tiba-tiba saja ada cowo menabrak ku dari belakang  ”oohh I am sorry” cowo yang menabrak ku
“o tidk apa apa” aku pun memblas perkataannya
setelah cowo itu meminta maaf aku segera meninggalkan tempat ku tadi dan menuju ke kelas ku yang baru.sesempai di kelas semua murid memperhatikan ku.Akupun hanya terdiam saja dan menuju ke tempat kursi kosong.Bel berbunyi tanda bahwa belajaran akan segera di mulai guru pun memasuki kelas kami.
“selamat pagi anak anak”sapa bu irma guru bahasa indonesia.
“selamat pagi bu”jawab siswa siswa yang ad di kelas dengan serentak.
“kebetulan sekali anak anak bahwa hari ini ada teman baru kalian.nah sekarang silakan maju untuk memperkenalkan diri kamu”ibu Irma sambil menyuruh ku
akupun maju”selamat pagi teman teman perkenalkan nma saya Fedellia Nafissya panggil saja fiya saya pindahan dari Surabaya saya pindah disini karna alasan saya ikut orng tua pindah tugas,hobby saya suka membaca,mudah mudahan saya bisa akrap sama kalian semua terimakasi”
aku yang gugup.akhirnya bu Irma menyuruhku untuk duduk.3jam pun berlalau bel berbunyi bertanda waktu istrahat telah tiba aku hanya duduk di bawah pohon bringin terdiam melamun membayangkan sesosok selaki tadi yang menabrak ku.”siapa yah nama cowo tadi.??tanya dlm hati.baru kali ini aku jatuh cinta pda pandangn pertama”aku trus melamun
tiba tiba sja cowo yang menabrak ku datng di hadpan ku.
“hei kamu kn cewe yang tadi aku tabrak..”dengn seyum manisnya
“ee..iya kamu yang tadi menabrak ku”akupun membalas senyumnya
“pekenalkan nma ku Aryo”sambil mengulurkn tangannya
akupun jga mengulurkan tangan ku”aa..kuu.. Fiya”.
Karna setiap hari aku bertemu aryo di sekolah lama kelamaan aku pun sama Aryo telah berpacaran.Aryo kakak kelas ku sedangkn aku adik kelasnya,akhirnya banyak orang yang iri pada ku karna aku bisa mendptkn cintanya Aryo yah mungkin karna Aryo ganteng,pinter,baik lagi.Aku dan aryo sangat saling mencintai dan sling menyayangi.tpi cinta ku sama Aryo tdk lama .aku di rumah hanya terdiam duduk di kursi sova sambil menunggu Aryo dtang
“hujan sederas ini Aryo belum saimpai,firasat ku kok jadi ngak enak kanya gini”bicara ku dalam hati.tiba tiba suara ketokan pintu bebunyi.Aku pun segera membukahkn pintu dan ternyata itu Aryo.
“eeh kamu,ayo masuk sayang,kamu basah pasti dingin ya .? Biar aku ambilin kamu handuk,tunggu sebentar.”aku sambil menatap wajah Aryo yang pucat dan Aryo hanya terdiam.akupun segera mengambil handuk dan tiba tiba saja suara hp ku berbunyi.Telfon dari kakaknya Aryo.akupun langsung mengankatnya
“hallo”aku
“hallo dengan Fiya .??”kakaknya Aryo sambil tergesak
“iya ini dengn saya sendiri ada apa ya kak.?”
“Fiya kamu harus dtang di rumah sakit sekarang,Aryo meninggal dunia akibat kecelakaan pas mau pergi di rumah kamu.”kakaknya Aryo sambil menangis
“apa kak.tpi Aryo ad di rumh ku kak”aku yang terheran dan mengeluarkan air mata
dan aku langsung mematikan telfon ku.Akupun menuju ke ruang tamu,pas aku sampai di ruang tamu ternyata Aryo tidk ada.tanpa kta lagi akhirnya aku menuju ke rumah sakit dengan air mata mengalir di pipi ku.sesampai di rumah sakit aku melihat Aryo terbaring dan di tutupi kain putih.Aku hanya bisa menangis
“Aryooo…Aryo bangun Aryo kamu jangn tinggalkan aku sendiri Aryoo..”aku yang terus menangis akupun perlahan menurunkan bibir ku di telinga Aryo sambil membisiknya
“Aku sayang kamu Aryo sampai kapan pun”bisik ku
lalu aku kembali menutupi kain putih yang menutupi tubuh Aryo dan mengucapkan SELAMAT TINGGAL CINTA KU.
