Abstract

Compressed air is one of the primary energy carriers used to operate pneumatic equipment and industrial processes. Moisture control is important for achieving the required air quality at the point of use. Refrigerated dryers reduce the moisture content of compressed air by condensing water vapor. Industrial field studies that jointly examine the hydraulic behavior and pressure dew point performance of refrigerated dryer lines under variable production demand remain limited. This study evaluated the hydraulic and pressure dew point performance of an industrial refrigerated dryer line under actual production conditions. Volumetric flow rate, line pressure, line pressure drop, and outlet pressure dew point were measured simultaneously. The flow rate ranged from 8.37 to 23.59 m³ min⁻¹. Line pressure drop ranged from 0.081 to 0.665 bar. The ratio of pressure drop to inlet pressure reached a maximum of 10.48%. The slope of the relationship between flow rate and pressure drop increased at higher flow rates. After initial conditioning, the outlet pressure dew point remained below the +3 °Ctd limit defined for water in ISO 8573-1. Short term changes in flow rate and pressure drop were not reflected in the outlet pressure dew point on the same time scale. This study provides field data at the system level for the simultaneous assessment of pressure dew point performance and hydraulic behavior under variable production demand.

Özet

Basınçlı hava, pnömatik ekipmanların ve endüstriyel proseslerin çalıştırılmasında kullanılan başlıca enerji taşıyıcılarından biridir. Kullanım noktasında gerekli hava kalitesinin sağlanabilmesi için nem kontrolü önem taşımaktadır. Soğutmalı kurutucular, basınçlı hava içerisindeki su buharını yoğuşturarak nem içeriğini azaltmaktadır. Bununla birlikte, değişken üretim talebi altında çalışan soğutmalı kurutucu hatlarının akış davranışı ile basınç çiğ noktası performansını birlikte inceleyen endüstriyel saha çalışmalarının sayısı sınırlıdır. Bu çalışmada, endüstriyel bir soğutmalı kurutucu hattının akış ve basınç çiğ noktası performansı gerçek üretim koşulları altında değerlendirilmiştir. Hacimsel debi, hat basıncı, hat basınç kaybı ve çıkış basınç çiğ noktası eş zamanlı olarak ölçülmüştür. Debi 8,37–23,59 m³ min⁻¹ aralığında değişmiştir. Hat basınç kaybı 0,081–0,665 bar arasında gerçekleşmiştir. Basınç kaybının giriş basıncına oranı en yüksek %10,48 değerine ulaşmıştır. Debi ile basınç kaybı arasındaki ilişkinin eğimi yüksek debilerde artmıştır. Başlangıç koşullandırma sürecinin ardından çıkış basınç çiğ noktası, ISO 8573-1 standardında su için tanımlanan +3 °Ctd sınırının altında kalmıştır. Debi ve basınç kaybındaki kısa süreli değişimler, aynı zaman ölçeğinde çıkış basınç çiğ noktasına yansımamıştır. Bu çalışma, değişken üretim talebi altında basınç çiğ noktası performansı ile akış davranışının eş zamanlı olarak değerlendirilmesine yönelik sistem düzeyinde saha verileri sunmaktadır.
