Performance evaluation, energy conservation potential, and parametric study of borehole heat exchanger for space cooling in building
A building integrated Borehole Heat Exchanger (BHE) has been designed and installed at Central Building Research Institute, Roorkee (29.87°N 77.88°E) India. The thermal performance and energy conservation potential (cooling potential) of installed BHE have been evaluated during summer months in the year 2013. The parametric study has also been done for its maximum performance. Quantitative assessment of CO2 mitigation has also been computed. The constant BHE water temperature (approximately 25 °C) witnessed the transferring of heat from air to water and vice-versa. It is found that the air temperature is reduced by 8–13 °C during summer season at air velocity of 18.9 m/s from the inlet of the BHE (exit of blower), whereas outdoor temperature was recorded as 35–39 °C. This system is capable of maintaining room temperature between 26 and 30 °C during peak summer season. The cooling capacity is evaluated between 150 and 180 kW h. BHE integrated with building can significantly reduce the 39836.25 kW h of electrical power needed for space cooling load and it can reduce global warming by substantially mitigating the carbon-dioxide to the tune of 50.10 tonnes annually. During the parametric study, it is found that double U-tube, circular pipe with optimum pitch of 4 in. is needed to achieve higher performance from the BHE.
