Capacity-controlled ground source heat pumps in hydronic heating systems

Design and Application of Heating System by Using Ground - Source Heat Pump for Isparta-Turkey Climate Conditions

“…The main objective of this work was to identify simple analytical equations that could be used to assess the optimum flow rate. There are more various study on the ground source heat pump and the hybrid of ground source with the sun that been very interested recently [3][4][5][6]. The experimental set-up of this study , described in the next section, is constructed and tested for the first time on the basis of an academic study performed in Isparta, Turkey .…”

Dynamic Simulation of a Variable-Speed Ground-Coupled Liquid Desiccant Air-Conditioner for Use in Subtropical Regions

“…One simple way is to control the compressor speed in order to modulate the capacity of the GCHP systems during the part-load operation. Various studies [12]- [16] had been made on the analysis of a variable-speed ground-coupled heat pump (VSGCHP) which helped indentify the range of operations in which energy-savings could be achieved. Meanwhile, Lee [17] investigated the dynamic performance of a VSGCHP system when applied to an office in three cities with different climates.…”

Energetic and Exergetic Performances Simulating of GSHP Greenhouse Cooling System in Northern China

“…The shallow geothermal energy (the solar energy stored in shallow soil layer and groundwater) has been well developed and applied in cooling and heating industrial and civilian constructions by making use of ground source heat pump (GSHP) technology [5,6], which has been proved with the characteristics of effective, environmental friendly and multi-functional of buildings heating, cooling and dehumidifying [7,8], which is indeed one of the most fast growing clean energy utilizing air-conditioning technologies at present. By the end of 2005, the utilization scale of ground source heat pump air-conditioning in resident or office buildings had reached 3000×10 4 m 2 in mainland China [9], and some research on GSHP technology in agricultural facilities cooling or heating were conducted in recent years [10,11].…”
