WECON PDP-3 series

An introduction to design principles & scope

This scheme entails the industrial pilot implementation and subsequent commercial promotion operations for an innovative small scale wind energy system. Anticipated power delivery is in the order of 3 KW out of a high-solidity 3.5m diameter rotor (higher capacities -10 & 50 KW- via utilization of the common technological features are easily attainable). The design offers significant advantages not only in comparative cost/performance and simplicity of construction and maintenance, but mainly in the capacity to readily serve in a mutlitude of domicile applications such as:

This overall design rational in the WECON PDP-3 aimed to deliver a product suitable for the actual needs of a modern domicile. In this respect, the power delivery requirements, are only a minor portion of the overall energy cycle, the primary percentage attributed to the thermal/cooling cycle. A direct cycle had to be designed as to offer utilization of wind energy in thermal conversion delivered in water heating/cooling, without prior conversion to an electricity cycle and without using complex engineering. This design feat became possible via conversion of wind energy to compressed air. As a secondary option, intermediate air-buffering provides an efficient torque stabilization during an electric power production cycle.

Wind energy exploitation for domicile or, small scale building applications, should focus on the actual overall energy cycle requirements, where electricity covers only a minor percentage. Space heating and cooling along with water heating, occupy nearly 60%. A common water cycle addressing all of these requirements, would provide a significant advantage in cost performance and simplicity of operation

The WECON PDP-3 (Pressure Dynamics Processor) series of wind energy conversion multi-purpose devices, represent a radically new approach in the field of amall scale wind turbines. A robust and cost-effective design, cooperates with the ANEMIRA engine for delivering 3KW in compressed air output, suitable for heating & cooling via an adapted heat-pump cycle, as well as electricity production, desalination and water pumping. The 3KW unit is particularly adept to Residential Integration. An upcoming option, is Hydrogen production via electrolysis and subsequent storage in Hydrides

The WECON PDP-3/10/50 (Pressure Dynamics Processor) series of wind energy turbines are based on solid and stable performance, designed with most proven research criteria. High solidity, high torque and low RPM, are critical factors for adoption in urban or suburban areas where noise and turbulent wind profiles, along with altitude restrictions, often pose imperative constraints. This level of performance is obtained with adoption of the NACA 4412 profile in 6 or 8 blade design, delivering an exceptional robustness and long operational service.

Among notable features of the innovative power uptake mode in tandem to the high torque rotor design, is sustained power delivery after the peak limit, at 8 m/sec wind speed. The diagram demonstrates a comparative performance curve with conventional rotor designs.

Among several highly innovative features in implementing a highly efficient Wind Energy power uptake system, was the original design and realization of a radically new approach in utilizing compressed air as the power delivery system. This computerized control pneumatic power system -codenamed "ANEMIRA" - provided a breakthrough approach for a number of critical application steps, as is electricity production, desalination and pumped storage.
