Hi everyone,
I’m troubleshooting an AHU that isn’t achieving its design cooling performance, and I’d appreciate any suggestions.
Current operating conditions:
Chilled water inlet temperature: **8°C**
Chilled water outlet temperature: **20°C**
Fresh air temperature: **22°C**
Off-coil air temperature: **17°C** (consistently)
Coil water flow: **15.8 m³/h**
Design off-coil temperature: **9.5°C**
We’ve already:
Cleaned the strainer.
Flushed the cooling coil.
However, the off-coil temperature remains around **17°C**.
Because of this, the supply air temperature stays high, and the space temperature remains above **22°C**, whereas the design space temperature should be below **19°C**.
Has anyone experienced a similar issue? What could be causing the coil to underperform despite the available chilled water flow? Could this be related to coil performance, air bypass, balancing, control valve issues, incorrect flow measurement, or something else?
Any troubleshooting suggestions would be greatly appreciated.

Hi everyone,
I’m an NRI living in the UAE, and I’d like to start investing in Indian mutual funds. I’m a complete beginner and have very little knowledge about investing.
My goal is to invest in:
One mutual fund for an emergency/safety corpus.
One mutual fund focused on long-term growth.
I have a few questions:
Which app or platform should I use as an NRI? (Groww, Zerodha, Kuvera, AMC websites, etc.)
Has anyone here gone through the NRI investment process? Was it straightforward?
Which mutual funds would you recommend for my goals?
Are there any important things or common mistakes I should know about before I start?
Any advice, step-by-step guidance, or personal experiences would be greatly appreciated. Thanks in advance!
