Daikin launches CO2-ZEAS condensing units

GERMANY: Daikin Germany has announced the launch this month of Daikin’s new inverter-controlled CO2-ZEAS refrigeration condensing unit for medium and low temperature applications. 

Previewed at the Chillventa exhibition in October, the CO2-ZEAS product range comprises three models covering nominal cooling capacities of 19-32kW and 11-17kW deep-freezing. The cooling capacity can be increased with the addition of Daikin’s Q-Up module.

As a transcritical, inverter-controlled compact compound system – equipped with three Daikin double-swing compressors and intelligent capacity control – the new CO2-ZEAS is suitable for a wide range of applications in normal and low-temperature refrigeration (evaporation temperature -40°C to +5 °C).

The units employ Daikin’s double swing compressor which has been specifically developed for CO2. With an isentropic efficiency of 69.5%, the compressor is said to make the CO2-ZEAS a very efficient machine. At the same time, the highly efficient compressor technology has a very low sound pressure level and requires little space.

The CO2-ZEAS includes Daikin’s standard heat recovery loop for easy on-site connection of a heat recovery unit. In addition, a standard integrated heat exchanger for the “high ambient kit” and refrigerant liquid sub-cooling is said to guarantee safe and efficient year-round operation in a wide range of temperature zones with ambient temperature from -20°C to +43°C. 

With a ready-to-use factory configuration of the controller, Daikin claims the CO2-ZEAS is almost a plug and play device. It also maintains that its free Refrigeration-Xpress design software makes project planning simple, intuitive and time-saving.
