BS 7074-3:1989 - Application, selection and installation of expansion vessels and ancillary equipment for sealed water systems - Code of practice for chilled and condenser systems
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This part of the BS 7074 series addresses the following:
1. System Types Covered
Chilled water systems: Systems that circulate cooled water for air conditioning or industrial process cooling.
Condenser water systems: Closed-loop systems used to carry heat from refrigerant condensers to external heat rejection equipment like cooling towers.
2. Primary Objectives
To ensure safe and reliable operation of sealed water systems.
To provide guidance on selecting and sizing expansion vessels.
To promote correct installation practices for all associated equipment (e.g., air separators, pressure relief valves, filling devices).
3. Key Elements Included
Expansion vessels: Guidance on capacity, pressure rating, positioning, and pre-charge requirements.
Ancillary equipment: Includes components such as:
Pressure relief valves
Automatic air vents
Pressure gauges
Make-up water systems
System layout and installation: Advice on:
Pipework configuration
Placement of expansion vessels (e.g., at the lowest pressure point)
Consideration of thermal expansion and contraction
Maintenance and commissioning: Emphasis on procedures for ensuring systems are properly filled, air is removed, and systems are tested for integrity and function.
