Systems requiring an air conditioning inspection

Only air conditioning systems with an effective rated output of more than

12kW are affected by these regulations. This will include systems consisting of individual units which are less than 12kW but whose combined effective rated output is more than 12kW.

The effective rated output is the maximum calorific output in kW stated by the manufacturer of the system as deliverable during continuous operation while complying with the useful efficiency indicated by the manufacturer.

One or more air conditioning units within a building controlled by a single person are considered to comprise a single air conditioning system for the purposes of the regulations.

The person who controls the operation of the system is the person who controls the technical functioning of the system, not someone who can just adjust the temperature or whose only responsibility is to adjust the controls.

For the purposes of the regulations, a building is defined as ’a roofed construction having walls, for which energy is used to condition the indoor climate’, and ’building unit’ means a section, floor or apartment within a building which is designed or altered to be used separately.

A building designed or altered to be used separately is where the accommodation is made or adapted for separate occupation. This could be indicated by the accommodation having its own access, separate provision of heating and ventilation or shared heating and ventilation, but with the ability by the occupier to independently control those services. For a non-dwelling the part could be deemed to be separate even if some facilities (e.g. kitchen and toilet facilities) were shared.

An air conditioning system is defined as ‘a combination of all components required to provide a form of air treatment in which the temperature is controlled, or can be lowered, and includes systems which combine such air treatment with the control of ventilation, humidity and air cleanliness’. This includes both fixed self contained systems, such as split systems and centralized systems. Mechanical ventilation systems that provide no mechanical cooling themselves, but serve spaces that are cooled by other means are included. Any components contained in air conditioning systems that are only intended to provide heating are excluded. Air conditioning systems that provide refrigeration for process applications, such as server rooms, would also require an inspection if that part of the system allows an inspection to be carried out.
