Abstract

Soğutma sistemlerinde soğutucu akışkan kaçakları montaj ve servis hatalarından kaynaklanabildiği gibi, zaman içinde boru ve bağlantılardaki titreşime ve malzeme yıpranmasına bağlı olarak oluşabilmektedir. Bu durum, soğutma sisteminin çalışma verimini engelleyerek, soğutma/ısıtma kapasitesini düşürme ve sistemde kızgınlık artışına neden olmaktadır. Ayrıca, emme hattında vakum düşüşü gerçekleşeceği için sisteme hava ve nem girişinden dolayı iç kirlenme ve tıkanma oluşmaktadır. Soğutucu akışkan kaçaklarının tespitinde köpükleme ve akışkan kaçak dedektörü ile algılama kullanılan en yaygın yöntemlerdir. Bu çalışmada, bir soğutma sisteminde oluşabilecek kaçakların tespiti için, kızılötesi görüntü işleme tekniğine dayalı yeni bir yöntem önerilmiştir. Bunun için ilk olarak, R22 soğutucu akışkan kullanılarak hazırlanan deney düzeneğinde, 7 farklı noktada, farklı zamanlarda yapay kaçaklar oluşturulur. Daha sonra, sağlam sistem kızılötesi görüntüsü ile yapay kaçak yapılmış sistem görüntüleri üzerinden daha önceden tespit edilmiş 12 alt bölgeden öznitelik verileri çıkartılmaktadır. Öznitelik özellik verilerinin elde edilme işleminde, belirlenen 12 bölgenin yüzey sıcaklık bilgileri kullanılmıştır. Yüzey sıcaklık bilgileri minimum, maksimum, ortalama ve en yoğun sıcaklık bilgisi olarak dört farklı şekilde çeşitlendirilmiştir. Kızılötesi görüntü analizi işlemini gerçekleştirmek için elde edilen öznitelik verileri Pearson Korelasyon Benzerlik Analizi (PKBA) işlemine sokulmaktadır. Son olarak, izlenmesi gereken 12 alt bölgenin PKBA sonuçları bir eşik değere tabi tutularak, eşik değerin altında kalan bölgelerde “Kaçak vardır” tespiti yapılmaktadır. Diğer bir olası durum ise, eğer sağlam ve kaçak kızılötesi karşılaştırmasında, benzerlik değerinin çok yüksek bir değer oluşmasında, bu bölgeler için “Kaçak yoktur” sonucunu vermektedir. Kızılötesi görüntü işleme tekniği kullanılarak gerçekleştirilen PKBA ile kaçak tespit işlemi, kullanım kolaylığı, hızlı ve eş zamanlı kaçak tespit etme noktasında daha avantajlı olduğunu göstermiştir.

Using Pearson Correlation Similarity Analysis Method on Infrared Images to Detect Refrigerant Leakage in Refrigeration Systems

Abstract

Refrigerant leaks in refrigeration systems can be caused by assembly and service failures, as well as due to vibration and material wear in pipes and connections over time. This situation prevents the working efficiency of the refrigeration system, decreasing the cooling/heating capacity and causing an increase in superheating in the system. In addition, internal contamination and clogging occurs due to air and humidity entry into the system, as there will be a vacuum drop in the suction line. Foaming and detection with fluid leakage detector are the most common methods used to detect refrigerant leakages. In this study, a new method based on infrared image processing technique was proposed to detect leakages that may occur in a refrigeration system. For this, firstly, in the experimental setup prepared using R22 refrigerant, artificial leakages are created at 7 different points and at different times. Afterwards, feature data are extracted from 12 sub-regions previously determined by using the robust system infrared image and artificially illegal system images. In the process of obtaining feature property data, the surface temperature information of 12 sub-regions determined was used. Surface temperature information has been diversified in four different ways as minimum, maximum, average and most intense temperature information. In order to perform the infrared image analysis process, the feature data obtained are entered into the Pearson Correlation Similarity Analysis (PCSA) process. Finally, the PCSA results of the 12 sub-regions that need to be monitored are subjected to a threshold value and the regions below the threshold value are detected as “There is leakage”. Another possible situation is that if the similarity value is very high in the comparison of robust and artificially illegal system infrared, it gives the result "No leakage" for these regions. Leakage detection with PCSA using infrared image processing technique has shown that it is more advantageous in terms of ease of use, fast and simultaneous leakage detection.
