Standing column well geothermal heat pump systems have recently attracted attention in many countries due to improved energy efficiency compared to conventional HVAC systems. In most geothermal heat pump systems, heat storage tank has significant impacts on the overall energy performance, affecting operating hours, part load ratio characteristics and COP. In this study, heating energy performance was comparatively analyzed with and without heat storage tank installation in order to quantitatively assess the effects of hot storage tank, by evaluating storage tank behavior, part load ratio characteristics and monthly and annual heating energy consumption. As a result, heat storage tank was able to maintain the tank temperature between 50 C and 60 C as expected and significantly reduced the operating hours of heat pump. More importantly, the case with heat storage tank turned out to save heating energy by approximately 21%, partially due to reduced operating hours and improved COP of heat pump. |
