Study on performance analysis of earth-air-pipe heat exchanger as passive cooling and heating system

Abstract

The energy demand for the private and business building increases quickly with the population. In the last two decade indicated extreme energy emergency found in creating nations particularly amid summer season. For hot atmosphere nations like India, the use of cooling framework assumes essential part. The Mechanical Vapor Compression (MVC) frameworks toward this path are demonstrating effective however in the present situation when the demand of energy is expanding, and the supply isn’t adequate one should center around the passive cooling techniques or other substitute which can meet necessity at least cost and energy utilization. As the passive cooling not just gives the course of the outside air to keep up the freshness yet in addition keep up the solace at low energy necessity, such a significant number of analysts have been working over these frameworks to discover it as a substitute of MVC units. Earth-air-pipe heat exchanger (EAPHE) can be utilized as a passive cooling and heating framework by using geothermal energy. This paper intends to display the audit on execution ponder and mechanical advancement of EAPHE at various atmosphere conditions. Exploratory outcomes demonstrate that normal temperature drops to 12–20 °C which can be accomplished that relies upon atmosphere conditions. Normal pipe length, measurement, and air speed inside pipe were discovered 10–100 m, 0.05–0.5 m, and air speed 2–5 m/s separately. These papers additionally recognize the purpose behind non-successful working of the EAPHE and proposed strategies to enhance the effectiveness of the framework to improve cooling of heating impact.
