Ground heat pump booster sp function-technical indices and rooms indoor climate

Abstract

The object of the study was heating pump Booster SP and indoor climate provided by floor and ventilation heating. The test site, laboratory of ‘Heating pumps and indoor climate’, was in The Estonian University of Life Sciences Institute of Technology. Heating pump together with ventilation system were set to automatically ensure proper indoor climate. The particularities of the laboratory setting are the alternative depth of the ground collector (1.5 m) and two indoor heating contours with different layouts. The operating parameters of heating pump were measured by thermocouple probes which were placed on the nodes of heating pump. Indoor climate, provided by heating pump Booster SP and ventilation system, was assessed with a diagnostics device which sensors were placed 1.5 m from the floor. The operating state of ground contour, two indoor heating contours, heating pump and indoor climate was diagnosed by simultaneous data accusation. Based on data processing the operating state and efficiency of heating pump, indoor climate’s compliance with laws and legislations was assessed
