Energy efficiency requirements for fans in unitary AC equipment
A new Advisory Note has been released to clarify Clause J5.4 and Clause J5.11 in NCC 2019 Volume One.
There has been some confusion about the application of J5.4 ‘Fan Systems’ of NCC 2019 Volume One, in particular, fans within unitary air-conditioning equipment. This may be due to unitary air-conditioning equipment also being covered by requirements of Clause J5.11. The Advisory Note has been released to clarify when fans within unitary air-conditioning equipment must meet the minimum requirements for fans in air-conditioning systems, as per Clause J5.4 and Clause J5.11.
The Advisory Note is available for download from the Resource Library.
