Energy Performance Monitoring and Examination of Electrical Demand and Consumption of a Geothermal Heat Pump System

Abstract

ABSTRACT The availability of geothermal energy as a renewable source and the favorable performance of heat pump systems provide an opportunity to meet the increasing heating and cooling needs in the building energy sector. However, developing a thorough understanding of how geothermal energy is used and how it affects the building energy performance provides motivation for studies conducted based on actual monitoring. The objective of this study is to examine the energy performance of a geothermal heat pump (GHP) system by means of monitoring the demand and consumption of electricity during heating and cooling operation modes in a commercial building. The literature review and several aspects of designing the particular GHP system related to enhancement of energy efficiency are discussed. The characteristic performance and results from actual monitoring of electrical energy demand and consumption of a GHP system are examined. It is observed that the need for cooling of the interior zones of the building r...
