MOB_-_HVAC_PLAN_(AS_BUILTS)_.pdf

This document is a comprehensive HVAC (Heating, Ventilation, and Air Conditioning) system design set containing detailed mechanical plans, sections, control schematics, and equipment schedules for a building project.

The HVAC plan encompasses multiple interconnected systems including air handling units, air-cooled and water-cooled condensing units, cabinet unit heaters, diffusers, fans, electric duct heaters, and humidification equipment. The document includes detailed mechanical equipment space plans showing equipment layout and piping connections, cross-sectional views illustrating vertical system integration, and specialized detail drawings for PAC (Packaged Air Conditioning) units, PAC condensing unit connections, and return air boot configurations. Control system diagrams depict AHU-1, AHU-2, AHU-3, and space temperature control sequences with corresponding sensor locations and operational logic. Equipment schedules provide specifications for all air handling units, condensing units (both air and water-cooled variants), cabinet heaters, diffusers, electric duct heaters, fans, and humidifiers, including capacity ratings, power requirements, and accessory details. The temperature control notes and legends define operational parameters, sensor types, and system interactions. General HVAC notes address design considerations such as ductwork specifications, refrigerant piping requirements, condensate drainage, vibration isolation, and maintenance access provisions. The document serves as a complete construction specification for HVAC system installation and serves as a technical reference for building mechanical systems coordination.
