Basics of Air Conditioning & Heat Load Calculation

This module covers core concepts of air conditioning and refrigeration, including system design factors, psychrometric properties, major components (compressors, evaporators, condensers, expansion devices), vapor compression refrigeration cycle, and alternative refrigeration systems. The module emphasizes understanding air properties, system components, and refrigeration cycles.

This module covers heat load calculations, thermal comfort, ventilation air, solar heat gain, transmission heat gain, internal heat sources, infiltration, sensible and latent heat, and cooling coil calculations. Students learn to assess various factors affecting HVAC system design through real-world samples and case studies.

This module focuses on practical heat load calculations using ISHRAE standards and Carrier Handbook, psychrometric processes, and their implementation. Students learn to calculate total heat gain for spaces, understand various air properties, and apply these concepts through sample calculations based on L&T's experience with large projects.
