Although air conditioning commissioning varies depending on the type of equipment installed and the application in hand, the principle remains the same, with the same considerations applying throughout the duration of a project. First, commissioning should not be left until the end of an installation; it needs to be considered throughout the system design process, as it is just as important as positioning the units correctly. It is crucial to factor commissioning time into a project, as a system cannot be switched on until the process has been completed. Building owners may be piling on the pressure and demanding units are activated as soon as possible but, without suitable commissioning, the system could be inefficient, develop faults — or even not function at all. Indeed, many common issues associated with commissioning are usually related to time constraints. If a project has been rushed or has overrun, there may have been mistakes made during the installation process, such as incorrect wiring or configuration settings. In addition to any mechanical and electronic issues, it is equally important that everyone involved in a project is shown how to correctly adjust controls.

This is a comprehensive two-day training class to introduce the full line of the Samsung DVM S, 3 phase air-cooled heat pump and heat recovery VRF systems. All of the DVM S indoor and outdoor units are reviewed including the operation features and installation guidelines. The field refrigerant piping and components are reviewed including the installation practices required. The complete commissioning steps are reviewed including component addressing, service and operation option settings. Attendees should be trained and experienced in heat pump systems and refrigeration standard installation practices.

Learn why the Commissioning Process CxP provides consistent, cost-effective, and successful delivery of new buildings and constructed projects, and enhances the performance of existing buildings. Gain tools and techniques to incorporate this quality process from pre-design through the life of the facility. Highly valuable for all project team members, this course covers CxP goals, process Where specified start-up, testing or commissioning procedures duplicate verification requirements of authority having jurisdiction, arrange for authority to witness procedures so as to avoid duplication of tests and to facilitate expedient acceptance of facility.

We are currently searching for an ambitious Commissioning Manager to lead commissioning Cx efforts for Utility Scale Solar and Wind projects. The components start to come together as a system during the commissioning phase. One Overall commissioning includes mechanical completion, leak tests, cleaning, flushing, provisional acceptance, pre-commissioning, first startup and post-commissioning. Careful planning is necessary for commissioning and startup. Integration of different systems, particularly control systems with others, has to be seamless.
