Daikin presented the new system to DIT so that students could get firsthand experience of working with innovative technologies that are setting the benchmark for future industry development. The Daikin Zeas system is a direct alternative to the traditional refrigeration “pack” system and is available in a range of capacities and styles which can be modularised to provide the optimum system capacity.
Each of the 16 students on the course installed an evaporator which is fed from the Daikin Zeas system. In addition, the project involved the installation of the main pipe work which helped them develop problem-solving and teamwork skills.
Every student worked individually on his own evaporator, and also as part of a team assigned specific duties for the common components of the installation. This involved the fitting of the unit-strut supports, fabricating evaporator pipe work, installing common pipe work and refnets, leak testing, strength testing, and commissioning.
Concern for the environment has led to increased demand by the refrigeration industry and food retailers for energy efficiency and environmentally friendly solutions. The growing popularity of neighbourhood corner shops and convenience stores has also made noise and size constraints an important factor.
To meet this demand, Daikin developed the Zeas range for deep freezing and medium temperature applications – compact refrigeration condensing units that offer high performance, low operating costs, low sound emissions and reliability. A single system can supply optimum cooling to multiple refrigeration units, each receiving just the amount of cooling capacity it needs.
Inverter control of the scroll compressor maintains high efficiency, even in partial load conditions, resulting in decreased CO2 emissions, reduced operating costs and highly efficient and reliable performance in a wide range of applications.
A new economiser function allows increased cooling capacity, and hence efficiency, without increasing system size. Zeas also introduces the use of R410A refrigerant in refrigeration applications. This is currently the best compromise available for the environment, energy efficiency and equipment cost. In terms of international shipments, implementing new technology can decrease refrigerated shipping cost.
Zeas provides adaptable cooling capacity for multiple evaporators or variable refrigeration loads in ambient temperatures from -15°C to 43°C, with evaporating temperatures from -45°C to +10°C. A range of models in single, double or triple compressor systems (from 5 to 20 HP) is available for freezing and cooling applications.
Low sound levels, including “night mode” operation, a compact footprint and easy installation make Zeas ideal for a range of applications including convenience stores and supermarkets, petrol station forecourts, cold and freezer rooms, and food processing.
Reliability is further increased by the use of advanced scroll compressor technology and high-quality components. To assure operational safety, each unit is tested in the factory.
