Inspection
Which systems require inspection?An air conditioning system is defined within the regulations as "a combination of all the 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". The regulations do not apply to process cooling systems and are being adopted in two phases. The first phase applies to systems with a rated cooling capacity above 250 kW and the second phase for the remaining systems over 12 kW. The cooling capacity of an air conditioning 'system' is further defined as "the sum of all individual cooling units under the control of one building owner or operator". It may therefore include smaller 'window-box' and split units which are considered to be part of the 'system'.
