This Trane Applications Engineering Manual provides comprehensive guidance on dehumidification within commercial comfort-cooling HVAC systems. It delves into the fundamental principles of psychrometric analysis, explores the performance characteristics of various HVAC system types (including constant-volume, variable-volume, and dedicated outdoor-air systems), and offers insights into improving dehumidification efficiency, particularly under part-load conditions.
Authored by John Murphy, senior applications engineer, and Brenda Bradley, information designer, this manual serves as a critical reference for professionals involved in designing building comfort systems. It addresses the importance of maintaining optimal indoor humidity levels for occupant comfort, building integrity, and air quality, referencing industry standards such as ASHRAE 62-2001 and ASHRAE 55-1992.
The document focuses on commercial applications and does not cover residential or specific process applications like industrial drying. It aims to equip engineers with the knowledge to effectively manage moisture and achieve desired humidity control in complex HVAC designs.
