Key Areas

The aim of the module is to prepare engineers for the process of designing a complete pipe-work system for delivering heating or chilled water to terminal units in buildings.  These types of system typically distribute heating or cooling water to radiators, fan coil units, chilled beams, radiant panels or chilled ceilings.

The module is primarily intended for junior to intermediate engineers who are being asked to design a system for the first time.  However, the module is not for the complete beginner.  There's an assumption from the outset that the user will have completed a college or university course on mechanical engineering, or possibly a course on building services engineering, and so will have some understanding of the basic fluid dynamic principles that underlie system design.  They will also have access to the support of a more senior engineer within their organisation who can guide them on the procedures and protocols for completing design drawings and specification documents.

Furthermore, the module does not explain how to design a complete heating or cooling system.  There is an assumption that heating and cooling loads have already been determined - based on building heat loss and heat gain calculations - and that, using the results of those calculations, the heating and cooling emitters have already been sized and their design flow rates specified based on whatever design temperature differential has been selected.

The module therefore deals with how to size the pipes, pumps and valves, how to layout the system and how to control its operation.

Course content

  • Pump sizing and selection                                           
  • Valves                                  
  • Choosing an appropriate control valve characteristic                       
  • Features to facilitate pre-commissioning cleaning

Who should attend

CIBSE online learning courses are suitable for those wishing to enhance and support their current knowledge base, as well as graduates within an engererial discipline. 

Each unit has been peer reviewed and tested through this group. The units allow students to take a coordinated journey through an individual topic or a series of topics. The units form the backbone of several corporate training schemes.
