预保温风管板厚度选择指南
预保温风管面板厚度选择不当容易导致冷凝、气流噪音增大和冷却损失过大等问题。GFI根据气流速度条件，针对“商场、医院、工厂和设备间”四大主要场景，编制了PID面板厚度选择的参考标准。PID型号选择说明：此表适用于[…]
如何解决PIR/PU预绝缘风管板上的冷凝问题
Proper routine maintenance and timely troubleshooting of PIR/PU pre-insulated duct panel are extremely important. Condensation, water leakage and mold growth on ductworks will damage ceiling decorations, raise air conditioning energy consumption, and impair indoor air quality as well as project inspection results.Standardized treatment Pre-insulated HVAC Duct Panel of condensation risks and full sealing protection are […]
PIR/PU预绝缘HVAC风管上出现冷凝现象的原因是什么？
在商业暖通空调项目中，管道上的冷凝水和滴水是一个普遍存在的问题。许多客户误以为仅靠PIR/PU保温板就能完全防止冷凝。实际上，材料选择、安装工艺、密封细节以及环境湿度都会直接导致管道表面出现水汽凝结和滴水。这个问题在沿海、热带地区尤为严重。[…]
PU/PIR 与酚醛风管板：真正的区别是什么？
比较用于暖通空调项目的聚氨酯/聚异氰脲酸酯（PU/PIR）和酚醛预保温风管板，包括其热性能、防火性能、制造工艺和实际应用选择。PU/PIR 和酚醛板均用于制造轻质预保温暖通空调风管。每种板都结合了硬质泡沫芯材和保护性覆层，因此风管外壳和保温层在一个制造过程中即可完成。[…]
Why Choose GFI PIR/PUR Pre-insulated HVAC Duct Panels?
As modern HVAC systems continue to demand higher energy efficiency, faster installation, and better thermal insulation performance, pre-insulated HVAC duct panels are becoming an important solution for commercial buildings and industrial ventilation projects. Among various insulation materials, PIR (Polyisocyanurate) and PUR (Polyurethane) foam duct panels are widely used in modern air conditioning and ventilation systems due to their […]
聚氨酯保温板与传统保温材料的比较
在现代建筑和暖通空调系统中，暖通空调保温板材料的选择直接影响建筑的能源效率、系统性能和长期维护成本。随着建筑能源标准的不断提高，传统保温材料的性能局限性逐渐显现。因此，工程师和项目开发商越来越多地采用高性能保温材料，例如聚氨酯保温材料[…]
How to Prevent Pre-Insulated Duct Leakage and Improve Airtightness
In HVAC systems, Pre-Insulated air duct leakage is one of the key factors that reduces system efficiency, increases energy consumption, and negatively impacts indoor air quality. This issue is particularly relevant in PIR, PU, and phenolic Pre-Insulated Duct System Although these ducts offer inherent advantages due to their integrated structure, improper design or installation can […]
翻新和改造项目中风管选择逻辑
暖通空调改造项目需要空间有限、能减轻结构负荷并最大限度降低长期风险的风管系统。对于可行性比材料价格更重要的建筑升级项目而言，轻质预保温风管正成为一种合理的选择。.
