Abstract: As the operating conditions of a heat pump system are the result of multiple interactions between the building and the heat pump system but also between heat pump and its thermal source being influenced by the climatic conditions a complex function between the location, season, consumption pattern, climate change and the thermal comfort exists. On the other hand the source and the sink temperature variation affect the annual performance of the heat pump as a heat generation system. The energy balance of the human body is necessary to be achieved for its thermal comfort which depends on several factors usually reflected by the ambient air temperature correlated with the surrounding-walls temperature. A better insulation of the outer walls can lead to a lower indoor temperature necessary for a better environmental comfort. Experimental data have been collected from a below the grade room assisted by a heat pump system. The purpose of the study was a more efficient operation of the system characterized by a reduced temperature swing of the walls, being less influenced by the air temperature amplitude and by the daily solar radiation. Energy savings resulting from a more efficient cycling operation in the limits of comfort can lead to possible conclusions regarding the architecture and the insulation of the walls.
