Level 3 Naming Conventions : Quidos Technical Support Log

Firstly, you will need to determine the naming conventions that you will be using for each of the elements of the project that you have looked at.

The air-conditioning certificate groups air-conditioning equipment into volumes, systems and components, in that hierarchy.

Volumes

If your inspection consists of a number of different out buildings, then you should choose to separate the buildings into different volumes.

In the example shown, three separate buildings within a hospital have been divided into three independent volumes, numbered from VOL001 through to VOL 003.

This is to enable the air-conditioning units within the buildings to have a unique volume identifier.

If you need to identify a particular air-conditioning component, then having independent volumes will make this task a lot easier.

An inspection does not necessarily need to have a number of buildings for you to break up the air-conditioning systems into volumes.

In this example, a school has had an extension built onto the side of an existing History block, and therefore you may choose to split the inspection into three distinct volumes.

An inspection does not have more than one volume. For most small buildings, it is very likely that only one volume will be present.

Systems

Within each volume you will have system components.

The system identifier identifies the air-conditioning equipment which influence the operation of each other.

For instance if two packaged split units serve the same room, the performance of one will affect the other, and would therefore form part of the same ‘system’ of cooling.

If two packaged split units serve different rooms then they do not affect the performance of each other. You may then define them as being separate systems.

Let’s look in more detail at the Physio block highlighted in the previous example.

We have defined the block as a separate volume, and within the block are two distinct methods of cooling , with a series of individual split systems and a separate multi-split system.

In this example, we would define there as being two systems present – one for the identical split systems and one for the multi split system.

Were one of the individual split systems servicing a completely separate room, then you would have three systems within the building.

In this instance the three systems would be given individual system names of SYS001, SYS002 AND SYS003.

Given that they are all within VOL002, this gives the systems full system IDs of VOL002/SYS001, VOL002/SYS002 and VOL002/SYS003

All units within a system must have been installed on the same date and have the same refrigerant type.

If two units are identical but have a different installation date or use a different refrigerant then they should be entered as different systems.

Unit Identifier

When entering information relating to Level 3 packaged systems, the main focus of your report is focused almost predominantly on the external condenser unit. You are required to give each external condenser unit an individual identifier in the format of PS01, PS02 etc. PS is an acronym for Packaged System.

The first condenser would be given an identifier of VOL002/SYS001/PS001
