This comprehensive Air Handling Unit (AHU) and Dedicated Outdoor Air System (DOAS) Commissioning and Test Plan outlines the essential procedures for the start-up, testing, and commissioning of these critical HVAC components. It ensures that AHUs and DOAS units perform according to their design specifications and operational requirements. The plan details pre-start checks, operational methodologies, testing procedures, safety arrangements, and necessary resources, including machinery, equipment, and personnel. Key aspects covered include site coordination, material storage, mandatory safety inductions, personal protective equipment (PPE) requirements, and the critical 'Permit to Work' system. The document provides step-by-step guidance for unit start-up, including initial motor inspections, fan rotation checks, and electrical parameter measurements. It also details the testing and commissioning phase, focusing on recording essential data such as on/off coil temperatures, Relative Humidity (RH), heat wheel performance, air velocity, air volume calculations, motor amperage, and voltage readings. This plan is vital for maintaining indoor air quality, energy efficiency, and system reliability. Ideal for HVAC Commissioning Engineers, Project Managers, Site Supervisors, Safety Officers, and HSE Managers.
