Abstract:
Air conditioning systems accountable a huge amount of energy consumption, the purpose of this work is to inspect the energy efficiency and the economic impact for air-conditioners using Wireless Sensing and Actuator Networks. Different methods are explored. Referring to ASHRAE Standard 62.1-2007 specified by manufacturers, the real case study tested for all rooms in the MUAB and using Wireless Sensor and Actuator Networks (WSAN) for detecting and assessing diverse technique of the conditioners in order to compare them with the existing on the market, the main results mention that the old conditioners should be replaced. Power parameters analysis proves that substituting actions applied in the main building enhance a preserving of 10% in the regular consumption of energy. Furthermore an investigation implemented to enclosure Stirling engine in air conditioning cycle demonstrate that can be a promoted solution and lessen meaningfully energy consumption, the novel numerical thermal model based on second order integrating irreversibility and energy losses tested on an alpha Stirling engine for the identical temperature and pressure governed in the refrigeration cycle show that it can be worked with energy efficiency around 42%.
