Özet:

 A variable speed thermoelectric TE air conditioner system is developed for efficient power management using intelligent control system. The investigation adopted Variable Voltage Variable Frequency VVVF regulator mode of a solid state electronic conversion system with integration of ACDC and DCAC Converter method. The system received power from the main 230VAC source and a step-down transformer converted it to 150VAC. The bridge rectifier converted the output voltage varying DCV by regulating the frequency. The DC voltage is transformed back into AC through Pulse Width Modulation PWM technique. The sinusoidal waveform is formed automatically by programmed microcontroller PIC18F4431 Insulated Gate Bipolar Transistor IGBT inverter that fed the air conditional compressor motor. The investigational results revealed that as the frequency declines, speed and torque drop which resulted to substantial reduction of power intake. The study reveals that 80,280kWh of energy is expended by a conventional air conditioner CAC in a month under steady operation while 15,624kWh is consumed by a thermoelectric air conditioner TEAC at the same period. This translates to energy cost of 602,100 NGN 387.51 USD and 18,063,000 NGN 11625.27 USD by conventional air conditioner CAC daily and monthly respectively while TEAC accounts for 117,180 NGN 75.42 USD and 3,515,400 NGN 2262.50 USD at the same period correspondingly. The energy savings cost with the developed TE drive are 484,920 NGN 312.09 USD, 14,547,600 NGN9362.78 USD and 174,571,200 NGN112353.31 NGN averagely on daily, monthly and yearly respectively. The estimated electricity in the study shows that 67 of the energy and cost bill is saved periodically using the developed TE drive likened to traditional climate control system.

 Değişken hızlı termoelektrik TE klima sistemi, akıllı kontrol sistemi kullanılarak verimli güç yönetimi için geliştirilmiştir. Araştırmada, Değişken Gerilim Değişken Frekans VVVF düzenleyici modunu içeren, ACDC ve DCAC dönüştürücü yöntemlerinin entegre edildiği katı hal elektronik dönüşüm sistemi kullanılmıştır. Sistem, 230V AC ana güç kaynağından beslenmiş ve bir indirgeme transformatörü yardımıyla 150V ACye dönüştürülmüştür. Köprü doğrultucu, çıkış gerilimini frekansı düzenleyerek değişken DC gerilime dönüştürmüştür. DC gerilim, Darbe Genişlik Modülasyonu PWM tekniğiyle tekrar ACye dönüştürülerek izole kapılı bipolar transistörlü IGBT inverter tarafından programlanmış bir mikrodenetleyici PIC18F4431 aracılığıyla sinüzoidal dalga formu oluşturulmuş ve klima kompresör motoruna iletilmiştir. Deneysel sonuçlar, frekans azaldıkça hız ve torkun düştüğünü ve bunun da önemli ölçüde güç tüketimini azalttığını ortaya koymuştur. Çalışma, geleneksel bir klima sisteminin CAC sabit çalışmada aylık 80.280 kWh enerji tükettiğini, buna karşılık termoelektrik klima sisteminin TEAC aynı sürede 15.624 kWh enerji tükettiğini göstermiştir. Bu, enerji maliyetlerinin geleneksel klima CAC için günlük 602.100 NGN 387,5 USD ve aylık 18.063,000 NGN 11,625.27 USD olarak hesaplanmasına karşılık, TEAC sistemi için günlük 117.180 NGN 75,42 USD ve aylık 3.515.400 NGN 2,262.50 USD olarak gerçekleştiğini göstermektedir. Geliştirilen TE sürücü sistemi ile günlük 484.920 NGN 312.09 USD, aylık 14.547.600 NGN 9,362.78 USD ve yıllık 174.571.200 NGN 112,353.31 USD tasarruf sağlanmıştır. Çalışmada tahmin edilen elektrik tüketimi, geleneksel iklimlendirme sistemine kıyasla enerji ve maliyet faturalarında 67lik tasarruf sağlandığını göstermektedir.
