Daikin is launching the new CO2 Round Flow cassette, the cooling / heating unit compatible and integrated into Daikin's CO2 Conveni-Pack system.

Daikin's Conveni-Pack CO2 system, in which Round Flow can be integrated, was developed and tested in the context of a LIFE project initiated by Daikin in January 2020 and co-funded by the European Community. The project, Natural HVACR 4 LIFE, is coordinated by Daikin Europe N.V in collaboration with Daikin Air Conditioning Germany GmbH and Daikin AC Spain. 

The goal is to demonstrate and evaluate “Conveni-Pack”, a combined solution of refrigeration, air conditioning and heating, pre-assembled and easy to install. The unit recovers the heat from the refrigerated cabinets and evaporators and reuses it to heat other areas of the building at no additional cost. Conveni-Pack uses R744 (CO2) as a refrigerant and the project studied the design features that improve the performance of this working fluid.

The first prototype was tested in a simulated convenience store, in the Daikin Europe plant in Ostend in Belgium. Demonstration and monitoring of the prototypes in real supermarkets in Germany and Spain, followed. The total duration of the project is approximately 3 years.
