The existing 3 large air handling units were already at the limit of their service life and also no longer met the current energy performance requirements of the building. It was therefore decided to replace the equipment by completely new one.
Since it is a large hypermarket, exchange of 122,000 m³ of air per hour is needed in the space. Each unit therefore has to deliver a minimum of 40,000 m³, which is a relatively high flow rate in the case of a heat recovery unit. Although high-efficiency and high-quality components are used, the size of the units is a major factor in planning the transport and handling.
The rotary heat exchanger section is almost 4 metres high and the same wide. The total length of the units then reaches 6 metres. To ensure maximum quality and tightness of the equipment, it was decided to deliver the rotary heat exchanger sections in one piece. Assembly on site would have been very complicated. As a result, their transport had to be planned long in advance. The units are located directly at the roof outlets, so that the outdoor pipe routes are kept to a minimum.
Number of AHU: 3
Minimum flow rate/AHU: 40,000 m³/h
Maximum flow rate/AHU: 42,000 m³/h
