Multi-circuit coil design increases total heat exchange area. Uneven refrigerant distribution among different circuits reduces overall heat exchange efficiency. Liquid refrigerant entering manifold splits and flows into each coil branch. Differences in pipe resistance lead to varying flow rate in every circuit. Xindacool optimizes manifold structure and branch pipe length, aiming for uniform refrigerant supply across all coil circuits. When flow distribution is poor, some circuits get excess liquid while other branches only receive gas refrigerant with little cooling capacity. Over-fed circuit faces risk of liquid carryover. Under-fed circuits run with high superheat and waste part of heat exchange surface. Installation level and pipe bending also affect flow split. Improper piping arrangement changes internal resistance of each branch pipeline. Oil accumulation in individual coil branches raises local resistance and further breaks original flow balance between circuits. During system commissioning, measure temperature of each circuit outlet. Temperature deviation indicates non-uniform refrigerant distribution. After coil cleaning or system overhaul, flow balance should be rechecked. Internal pipe state changes may alter flow distribution. Filter before manifold prevents solid debris from blocking single branch. Partial blockage will cut flow in that circuit and create temperature difference. For large evaporators with many coil circuits, manifold insulation avoids preheating liquid refrigerant before entering heat exchange coil.
Q: What problem appears with uneven refrigerant distribution in multi-circuit coil? A: Some branches get too much liquid while others lack refrigerant, reducing total cooling performance. Q: How does manifold affect refrigerant split? A: Optimized manifold structure helps evenly distribute liquid refrigerant into each coil branch. Q: What symptom shows unbalanced circuit flow? A: Obvious temperature difference measured at outlet of different coil branches. Q: What risk for over-supplied coil circuit? A: Liquid refrigerant may pass through coil and flood back towards compressor. Q: What effect of oil accumulation inside one branch? A: It increases local pipe resistance and destroys flow balance among all circuits. Q: Why install filter before manifold? A: Block solid impurities to avoid partial blockage of single coil branch. Q: What impact of manifold without insulation? A: Liquid refrigerant absorbs heat before entering coil and reduces effective cooling capacity. Q: When to recheck multi-circuit refrigerant balance? A: After coil chemical cleaning or complete refrigeration system overhaul.
