BS EN 1886:2007

This CPD will assist attendees understand the difference between model box and real unit testing and cover the testing and classification criteria of BS EN 1886:2007, before going into greater detail on mechanical strength, casing and filter bypass leakage, thermal performance, acoustic performance and fire & safety recommendations. This course is aimed at consultants and facility management teams, involved the specification, testing and/ or maintenance of air handling units in public buildings and commercial spaces.

Topics covered:

• Introduction to BS EN 1886:2007
• Mechanical Strength
• Casing and Filter Bypass Leakage
• Thermal Performance
• Acoustic Performance
• Fire and Safety Recommendations

The high social impact of carbon emissions, leading to short term deterioration of air quality and long term climate change issues, keeps energy efficiency high on the agenda of most organisations. Globally, we continue to address the need to be more sustainable and this CPD considers the implications on efficiency of AHU design, the external factors that will influence AHU performance and offers detailed insight and understanding on how to maximise efficiency whilst minimising the impact on performance.
This course is aimed at consultants and facility management teams, involved the specification, testing and/ or maintenance of air handling units in public buildings and commercial spaces.

Topics covered include:

Introduction

Definitions

AHU Design

Installation

Operation

Most large data centres now operate using chilled water cooling. Much of the improvement focus over the past decade has been on the equipment itself, but the chilled water system as a whole is now under the spotlight. As data centres get larger and the industry becomes globalised, one of the things we’re seeing is a move to variable primary-only chilled water systems. The challenge with these systems is the robust controls loop protocols to ensure the system delivers resilience and redundancy at the lowest possible energy output. Often a BMS is used to mange the system, but often the level of built-in modification, control and protection of the system that we believe is required is not something that a BMS provider could achieve alone. This CPD introduces the idea and recommended specification of a dedicated real-time decision making tool delivering required cooling, maintaining redundancy levels, increasing resilience, all at the lowest possible energy outlay and while maintaining the system within the cooling equipment’s stated operating envelopes.
This course is aimed at anyone involved in specifying chilled water systems and associated controls in large data centres.

Topics covered include:

The trend towards variable primary rings and what they look like

The evolution of controls systems and the role of the BMS.

The requirement for an additional control system and what this should look like.

How CRAHs, chillers and the system as a whole should be programmed to behave.

Resilience and security implications.

Pressures on natural resources are driving data centre cooling system designers back to the drawing board in order to maintain resilience and redundancy at the lowest possible energy cost. All this is happening in the face of pressures from Governments, communities, clients and the planet itself as weather becomes more extreme and unpredictable.
