Daikin has further developed its tried-and-tested Conveni-Pack cooling system specifically designed for food retail and petrol station applications in city centers and residential areas to create environment-friendly natural refrigerant CO2 version. The result is a very efficient all-in-one solution which combines food refrigeration, heat recovery, heat pump and air conditioning in one unit, to meet the commercial refrigeration requirements of the European food retail sector. With a GWP (Global Warming Potential) of 1, the natural refrigerant CO2 is particularly climate-friendly. Supporting food retailers to achieve their environmental goals while saving up to 50% of their annual energy costs.
Junji Umamoto, Vice President and Director Refrigeration, Daikin Europe said: “With the Daikin CO2 Conveni-Pack, we have made an important step forward to meet the need for commercial refrigeration, heating and air conditioning in one sustainable and energy-efficient system. By using the latest controls and inverter technology, we achieve energy savings of up to 50% compared to conventional systems.”
The Daikin CO2 Conveni-Pack achieves a heat recovery of up to 100% from the refrigeration cabinets and uses it for the seasonal heating of the sales area and functional rooms, without additional energy supply.
Daikin has developed its own CO2 swing compressor to ensure reliable operation. The new swing compressor specially designed for CO2 refrigerant with two-stage compression and efficiency of 69.5% uses the most performing hermetic compression currently available. It ensures 5 to 15 per cent higher efficiency of the Conveni-Pack under nominal operating conditions. The life expectancy of the new compressor is significantly longer due to a low discharge temperature (maximum 100°C) and more precise control of the oil temperature.
The new CO2 Conveni-Pack is available in 2 variants. The smaller Conveni-Pack AC10 for smaller to-go supermarkets or petrol stations with a refrigeration capacity of 14,5 kW and heating capacity of 22 kW and the Conveni-Pack AC15 with a refrigeration capacity of 21 kW and heating capacity of 22 kW for medium-sized food retail stores. The operating range lies at -20°C to +43°C outdoor temperatures. The compact build of both models allows for a flexible and space-saving installation. The outdoor unit can be placed up to 35 metres above, 10 metres below or at ground level and up to 130 metres away from the indoor units. The CO2 Conveni-Pack scores further point with its low-noise operation and the possibility of indoor installation.
