Geothermal Energy in Building Automation: An Exploration of Ground Source Heat Pumps and Heat Exchangers

Vrushank Mistry


Abstract: Ground source heat pumps are not entirely new; they have been in use for several decades. However, their adoption rate has been influenced by various factors like initial installation cost, lack of awareness, and geographical conditions. Despite these challenges, interest in GSHPs has been on the rise, especially in regions with favorable conditions and in areas where energy prices and environmental concerns make them a viable option. In recent years, with the growing emphasis on sustainable building practices and renewable energy utilization, GSHPs have witnessed increased adoption in various parts of the world. They're especially popular for buildings aiming for green certifications, such as LEED. Introduced in the late 20th century, Ground Source Heat Pumps (GSHPs), often known by names like GeoExchange or earth - coupled mechanisms, leverage the Earth's steady subterranean temperature as their primary medium for thermal exchange. Unlike the fluctuating air temperatures that various regions experience, from intense summer heat to freezing winter cold, the Earth's underground temperature remains stable, typically ranging between 45?F (7?C) and 75?F (21?C). This underground environment, reminiscent of a cave, is naturally warmer than the winter air and cooler than the summer air. GSHPs utilize this temperature disparity, exchanging heat with the Earth via a dedicated ground heat exchanger, enhancing their operational efficiency. GSHPs, like their counterparts, can heat, cool, and when equipped, provide homes with hot water. Advanced geothermal models come with dual - speed compressors and adjustable fans, ensuring optimal comfort and energy conservation. When compared to air - source heat pumps, GSHPs offer advantages: they operate more silently, boast longer lifespans, require minimal upkeep, and their efficiency is not compromised by external air temperatures.
