Abstract
Sistem pemanas heat pump pada proses Clean In Place (CIP) memerlukan kontrol temperatur yang stabil untuk menjamin kualitas, efisiensi energi, dan umur peralatan. Penelitian ini menganalisis perbandingan karakteristik respons kontrol on–off dan PID pada sistem pemanas heat pump industri untuk proses CIP. Model matematika sistem dikembangkan berbasis prinsip termodinamika sebagai fungsi transfer First Order Plus Dead Time (FOPDT) dengan parameter fisik seperti volume tangki 2,5 m³ dan laju alir 30 m³/jam. Simulasi closed-loop dilakukan di MATLAB/Simulink selama 24 jam, dengan kontrol on–off dikonfigurasi histeresis ±2°C dan kontrol PID dituning menggunakan PID Tuner Toolbox dilengkapi fitur anti-windup metode clamping. Hasil menunjukkan kontrol on–off menghasilkan ripple temperatur sebesar 6,0533°C dengan steady-state error 0,1112°C, sedangkan kontrol PID mencapai Settling time 278 detik dengan steady-state error nyaris nol (0,0001°C) dan ripple lebih halus (1,3422°C). Perbedaan signifikan dalam stabilitas temperatur ini berdampak pada kualitas proses CIP, di mana fluktuasi besar pada kontrol on–off berpotensi menyebabkan ketidakseragaman pembersihan dan risiko kontaminasi. Studi ini merekomendasikan kontrol PID sebagai metode yang lebih optimal untuk sistem pemanas CIP guna memastikan kestabilan temperatur dan kualitas proses.

Stable temperature control in heat pump heating systems for Clean-in-Place (CIP) processes is essential for ensuring product quality, energy efficiency, and equipment longevity. This study analyzes the comparative response characteristics of on–off and PID control methods in industrial heat pump heating systems for CIP applications. The system's mathematical model was developed based on thermodynamic principles as a First Order Plus Dead Time (FOPDT) transfer function, incorporating physical parameters such as tank volume (2.5 m³) and flow rate (30 m³/h). Closed-loop simulations were conducted in MATLAB/Simulink for 24 hours, with on–off control configured with ±2°C hysteresis and PID control tuned using the PID Tuner Toolbox with anti-windup features. Results demonstrated that on–off control produced significant temperature ripple of 6.0533°C with a steady-state error of 0.1112°C, while PID control achieved a Settling time of 278 seconds with near-zero steady-state error (0.0001°C) and smoother ripple (1.3422°C). This significant difference in temperature stability directly impacts CIP process quality, as excessive fluctuations in on–off control may cause inconsistent cleaning performance and contamination risks. The study recommends PID control as the more optimal method for CIP heating systems to ensure temperature stability and process quality.
