So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Soğutma sistemlerinde ilk yatırım ve işletme maliyetleri ısıtma sistemlerine göre daha yüksektir. Bu nedenle soğutma sistemlerinde yapılacak verimlilik çalışmaları ısıtma sistemlerine göre daha faydalı olacaktır. Kondenser üzerindeki sıcaklığın yüksek olması dış ortam koşullarına bağlı olarak ısısını yeteri kadar atamamasının bir göstergesidir. Isısını istenilen düzeyde atamayan soğutucu gaz ise tamamen sıvı hale dönüşmez. Bu da soğutma sisteminin verimini düşürür. Bu çalışmada klima iç ünitesinde oluşan yoğuşma suyunun dış üniteye (kondensere) aktarılmasının performans üzerinde olan etkisi deneysel olarak araştırılmıştır. Bu bağlamda, 9000 btu inverter split klimanın soğutma modunda çalışırken iç ünite eşanjörü üzerinde oluşan yoğuşma suyunun dış ünite eşanjörüne aktarılması sonucunda enerji tüketimi, ortama üfleme sıcaklığı, iç ünite emme sıcaklığı, dış ünite üfleme sıcaklığı, kompresör gaz çıkış basıncı, evaporatör gaz giriş ve çıkış basıncı üzerinde etkisi incelenmiştir. Dış ünite eşanjörünün üzerine aktarılan yoğuşma suyu soğutucu akışkanın yoğuşmasını kolaylaştırmış, harcanan elektrik sarfiyatında ve iç ünite üfleme sıcaklığında belli bir miktar düşüş sağlamıştır. Üfleme sıcaklığına bağlı olarak soğutulan mahalin sıcaklığında da belli bir miktar azalma görülmüştür. Sonuçlara göre azalma oranının dış ortamın nem ve sıcaklığına bağlı olduğu tespit edilmiştir.

Condensers in the cooling systems Refrigeration by cooling water: Example of the name
2020
Author:  
Abstract:

The initial investment and operating costs in cooling systems are higher than the heating systems. Therefore, the efficiency work in the cooling systems will be more useful than the heating systems. The high temperature on the condenser is a indicator of the fact that it is not sufficiently tempered depending on the external environmental conditions. The cooling gas that does not assign its heat to the desired level does not become completely liquid. This reduces the efficiency of the cooling system. In this study, the impact of the transmission of concentration water formed in the internal unit of air conditioning to the external unit (condensers) on performance has been experimentally studied. In this context, the 9000 btu inverter split climate is working in cooling mode while the consumption water formed on the internal unit equator is transferred to the external unit equator as a result of the effect on energy consumption, environmental floating temperature, internal unit absorption temperature, external unit floating temperature, compressor gas output pressure, evaporator gas input and output pressure. The exhaust water transmitted over the external unit equator facilitated the exhaust of the coolant fluid, provided a certain amount of decrease in the electricity consumption and the internal unit floating temperature. The temperature of the refrigerated neighborhood was also a certain amount reduced depending on the temperature of the flour. According to the results, the decrease rate has been found to be dependent on the moisture and temperature of the outside environment.

Enhancing The Performance Of Cooling Systems By Cooling Condenser: Adiyaman Case Study
2020

Abstract:

Initial investment and operating costs in cooling systems are higher than heating systems. Therefore, efficiency increment in cooling systems will be more useful than heating systems. The high temperature on the condenser is an indicator that it does not adequately release its temperature depending on the external environment conditions. The refrigerant cannot completely liquified when it cannot release its heat in the condenser. This reduces the efficiency of the cooling system. In this study, the effect of transferring condensed water in the inner unit to the condenser on the performance has been investigated experimentally. In this context, air conditioning system (9000 BTU/h) has been selected and condensed water in inner unit of the system has been transferred to the condenser unit. Then the effect of using this modification on energy consumption, average blowing air temperature, suction temperature of evaporator, output pressure of compressor, inlet and outlet pressure of evaporator has been studied. Depending on the blowing temperature, a significant reduction was observed in the temperature of the cooled area. In the modified system, evaporator blowing temperature was decreased between %5-10.8. According to the results, it was determined that the rate of decrease depends on the humidity and temperature of the external environment. In addition, a maximum reduction of 6.4% in the condenser blowing temperature was recorded.
