Heating and cooling performance analysis of a ground source heat pump system in Southern Germany

Ground source heat pumps as high efficient solutions for building space conditioning and for integration in smart grids

“…Due to these reasons the HPs performance results achieved in different GSHP installations in buildings within different weather conditions (cold, mild or hot climates) are difficult to compare. For example, in Southern Germany the performance of a GSHP system installed in an office building was investigated and it was found a Seasonal Performance Factor (SPF) of 3.4 for winter and an SPF of 8.2 for summer [23]. In the Mediterranean coast of Spain the performance of a GSHP system installed in an academic building equipped with fancoils presented at the end of the heating season a SPF of 3.5 and at the end of the cooling season a SPF of 4.3 [24].…”

Heat pump for thermal power production in dairy farm

“…MA et al (2014) proposed to use solar energy heat pump systems in farms, however, exploiting either heating or cooling individually. Moreover, some heat pump systems have been studied for home application; yet few studies have reported results in farming areas by using distinct sources of energy (STAFFORD & LILLEY, 2012;LUO et al, 2015;VIEIRA et al, 2015).…”

Performance evaluation before and after solar seasonal storage coupled with ground source heat pump

“…However, so many buildings are in heating-dominated or cooling-dominated areas in China, resulting in that the heat extracted from the soil and rejected to it are not necessarily equal [6], therefore some bottlenecks came up, like soil thermal imbalance leads to soil temperature change, and further, leads to the COP deterioration of GSHP system and heat pump unit [7], especially in heating-dominated climate zones [8], where the soil temperature declined gradually year after year due to imbalance energy loads. To make the soil thermal balance and keep the GSHP system and heat pump unit run at a high COP level, a makeup heat is needed to input to the soil [9].…”
