Growing international concern for the environment has led to an increase in demand for environmentally conscious, energy saving product solutions for the industrial, commercial and retail sectors of the refrigeration market. That said, the rapid increase in the application of refrigeration to corner shops, convenience stores and petrol station forecourts in residential areas has highlighted the need for constraints on equipment operating noise and size.
Daikin Europe NV has met this situation by developing the ZEAS range of compact, high efficiency, low noise and low operating cost condensing units for deep freeze and medium temperature applications. Two parallel ranges are available, each with 7 models and 1, 2 or 3 compressors, with capacities of 12.2kW to 37kW for medium temperature (-100 C to 320 C) applications and 5.41kW to 15.1kW for low temperature (-350 C to 320 C) applications.
ZEAS therefore, offers highly flexible freezing or cooling for cabinets and single or multiple evaporators or variable refrigeration loads in ambient temperatures from -150 C to 430 C with evaporating temperatures from -450 C to 100 C. Low operating noise levels plus a night set back mode, compact footprint and easy installation characteristics make ZEAS the ideal medium capacity solution for supermarkets, wholesale, retail and convenience stores, cold and freezer rooms, petrol station forecourts and food processing areas etc.
Daikin has harnessed and applied the experience and technology inherent in its VRV system -- which revolutionised the comfort cooling industry – to commercial refrigeration applications. The end result is a system that can supply optimum cooling to multiple terminal units with precisely the degree of cooling required. Advanced inverter control of the semi hermetic scroll compressor varies output according to required cooling load, even in partial load conditions, maximising energy efficiency, decreasing carbon emissions and reducing operating costs. Furthermore, the use of DC motors (on the fans as well as the compressor) minimises the frequency of stop/start cycles and underpins excellent unit reliability throughout an extended operating life.
A new economiser function also increases cooling capacity and hence efficiency, without any resultant increase in unit size, whilst the use of R-410A, currently the best refrigerant available as regards the environment, ensures optimum energy efficiency and minimum capital cost.
