Industrial HVAC Heat Exchanger Calculations & PI&D

I'm seeking an expert in HVAC systems for industrial applications to perform critical calculations for a heat exchanger in our system.

Key requirements:
- Calculate the thermal performance of the heat exchanger
- Assess the pressure drop across the system
- Evaluate flow rates under various operational conditions

I am particularly interested in professionals with substantial experience in industrial HVAC systems and heat exchanger analysis. Knowledge of relevant software tools for calculations and simulations is a plus.
