In April 2024, a special project was implemented for AHT. In the downtown area of Hamburg, on the ground floor of a residential building, is Mr. Lade’s EDEKA market. Previously, a remote cooling and freezing system with F-gases was installed. Notably, the cooling unit is placed in front of the store between the sidewalk and the street, and two CO₂ cold room units are to be integrated into the SPI system. Due to the professional advice from AHT and the fact that AHT has already installed numerous SPI systems worldwide, the customer decided on the innovative SPI HYBRID system.
To avoid operating the CO₂ cold room units with an own compressor and gas cooler, AHT decided to use the SPI HYBRID system. A classic SPI system (Waterloop) is set up and all components are connected. The CO₂ cold room units are then directly connected to the SPI system via a heat exchanger box. This way, the waste heat from the CO₂ units is directly fed into the SPI system and dissipated via the external cooler. Thanks to this innovative solution, the CO₂ cooling room units could be integrated into the SPI system.
