This ‘size’, when subject to external conditions creates large heat loads within the hall (See Heat Load section later). If necessary, the fresh air is heated or cooled. With mode 4 the outside air supply could be delayed for circa ¼ hour. This approach will reduce the total cooling load.Note: NOT air conditioning the entire volume will significantly reduce plant sizes and running costs. Our Services. Outside air can be via natural means (comply with NCC F4.6) or by mechanical means (comply with AS1668.2). e: jorgenk@knoxadv.com.au | t: 02 800 33 100 | w: KAE Diagram 3 – High Level AC – Incident AC Loads.
