What are some common challenges and limitations of psychrometric processes in HVAC systems?

Psychrometric processes in HVAC systems can be challenging to design and optimize due to various factors, such as non-linear relationships between psychrometric properties, complex air flow patterns, and uncertainty in system parameters. Additionally, psychrometric processes can be limited by factors such as equipment capacity, energy efficiency, and maintenance requirements. Understanding these challenges and limitations is essential for designing and optimizing HVAC systems that meet the required performance, efficiency, and sustainability standards.
