About this file
This schematic diagram is a Revised Hydronic System and DOAS (Dedicated Outdoor Air System) Schematic for the State of Michigan, specifically the Department of Health and Human Services (MDHHS) Design and Construction Division. The technical drawing details a complex mechanical system involving heat pumps, air handling units (AHUs), temperature sensors, control valves, and various piping configurations for water treatment, heating, cooling, and ventilation systems. The diagram includes specific equipment like DOAS-1, AHU-1, AHU-2, AHU-3, and multiple pumps and heat exchangers, with a focus on integrating new equipment with existing building automation systems.
The schematic emphasizes several key operational sequences, including maintaining specific temperature controls, managing heating and cooling modes, and ensuring compatibility with the existing building automation system (BAS/DDC). Notable requirements include interfacing new equipment with the central BAS, retaining existing peer-to-peer network controllers, using only current manufacturer products, and ensuring spare parts availability for at least 10 years after contract completion. A specific note highlights the need to separate the fire protection system from the hydronic system, indicating a comprehensive approach to system design and safety integration.
