Special Blades of ESS Ventilation Systems	Energy Saving System (ESS) in Aerodynamic Tunnel by Testing

All conventional Axial Flow Ventilators & Compressors are working today in range of partially or fully developed separation of flow on their rotating blades with vast cavities of turbulent air formed. This causes low efficiency (not more than 32%), high-energy consumption and high level of noise and, as a consequence, high exploitation cost.After several years of comprehensive Research, Development & full-scale Prototypes Trials in Aerodynamic Test Stand (Tunnel), ISCOM succeeded in developing new innovative economical efficiency Energy Saving System - ESS for all kind of Stationary & Transport ventilation, air-condition, cooling, heating & compressor application. The ESS system is unique, competitive with all systems currently available in the world.

The invented ESS System is working on such principle, that the separation of airflow around blades is avoided with laminar flow of air. Therefore the efficiency of ESS is high (~ 60%) and with unique structure, shape & design, provides not less than 27,3% energy saving in the range of the efficiency gain (see following trial sheet & graph).

As shown in the following trial sheet & graph an increase in efficiency of 27,3% was achieved by simply replacing the existing convential blades by special blades.

The unique structure, design & shape of the ESS system grants it several distinct advantages over the current Systems:

2.1 Universality to all kind and dimensions of industrial & home appliances ventilation, air-condition & compressor installations:

• Stationary (Ventilators , Refrigerators, Airconditioners, Airdistributions Systems , etc.)
• Commercial & Military Transport (Land & Rail vehicles, Ships, Aircrafts , etc.)
• New and Replacement Systems

2.2Significant saving in energy (Electricity, Fuel , etc.) consumption. Installing the offered System will save not less as 27,3 % of Electricity consumption in Axial Fans comparable with the Convential Fans

2.3Substantial reduce noise level due to very high accuracy of geometry of blade profiles, their luster-smooth surface and vibration absorbing properties of advanced composites used for construction Blades.

2.4Simple and easy installation new & replacement ESS Systems due to the unique ESS structure and low weight of advanced composites used for construction blades.

2.5Lower cost for the consumers - the cost of advanced composites used for construction blades, it production & installation, is lower than the costs of the traditional Systems

2.6Ecology clean of ESS production Process

2.7Excellent resistant of ESS to corrosion & environment hazards

2.8No maintenance Cost of ESS

2.9Life time lasting of ESS

3.1 Calculation & Drawing of ESS for diameters 620, 912,1500mm are made.

3.2 For testing ESS System (diameter 620mm) following developments were made:

• Design & production of Aerodynamical test tunnel according to international standards
• Design & building of wooden patterns, casting iron molds for production set of novel ESS steel blades
• Production of stand for balancing axial fans with novel ESS blades

3.3 Tests of Energy economy of ESS axial fans were positive and showed an increase in efficiency of 27,3% in electricity by using novel ESS axial fans instead of conventional fans
