CFD ANALYSIS OF SOLAR OPERATED EARTHEN POTAIR COOLER

Abstract

The present air-ventilation methods are evaporative coolers, air conditioning, fans. But running these products need high-rate electricity. The production of electricity is ultimately responsible for hot and humid conditions i.e., global warming. In hot and humid conditions, the need to feel relaxed and comfortable has become one of few needs and for this purpose utilization of systems like air-conditioning and refrigeration has increased rapidly. These systems are most of the time not suitable for villages due to longer power cut duration and the high cost of products. Solar power systems being considered as one of the paths towards more sustainable energy systems, considering solar cooling systems in villages would comprise of many attractive features. This technology can efficiently serve large latent loads and greatly improve indoor air quality by allowing more ventilation while tightly controlling humidity. Despite increasing performance and mandatory energy efficiency requirements, peak electricity demand is growing and there is currently no prevalent solar air-cooling technology suited to residential. This research CFD analysis of solar operated earthen pot air cooler for domestic applications. Velocity airflow within the Earthen Pot in that air velocity has been increased with reducing the pressure results the temperature variation. In Temperature contour the temperature rate reduces with 8 to 10 OC of room temperature and the analysis gives the temperature difference and air velocity variations.
