The SGV system was consisted of seven PVC parallel pipes (length of 50 × 0.25 × 3.5 m), a sump drain well designed for cleaning air pipes, and a centrifugal fan for breathing air into the buildings. All pipelines were arranged with 8 ‰ equal slope, and the distance between each pipe...
The Navasota's interior outfit has been constructed to a high standard, including mahogany trim in the pilothouse, staterooms, and galley as well as custom-built mahogany tables, desks, and cabinets. General workmanship throughout the vessel reflects this same high quality and attention to detail...
Maximum concentrations of PFOS and PFOA in this study were well below the US EPA's provisional health guidelines (200 and 400 ng/L, respectively). However, these guidelines were developed for short-term exposures; the state of New Jersey has set a PFOA guideline for drinking water that is ...
However, GSHPs suffer from higher upfront drilling and installation costs than other competing heating technologies. Therefore, the optimization of expenditures is essential for owning and operating these systems [8]. There is another heat pump setup that uses ambient air (as well as waste heat, ...
Aims were therefore 1) to characterize the seasonal dynamic of the nutrient pattern as well as the phytoplankton and zooplankton succession over a one-year period, and 2) to identify the driving factors of cyanobacterial development over 13 years of monitoring, testing the hypothesis that nutrients...
(BHE) field for seasonal geothermal storage. The heat sink side, i.e., the military camp will only be used in terms of energy demand. The dimensioning, configuration and simulation of the low-temperature heating and cooling grid as well as the decentral heat pumps is not part of this ...
Tubewell ID-17 became too tight to pump water (due to an increase in the height of the barrel of the handpump) after the installation of Zimba. We received complaints from household users that they were unable to pump water. Only three water samples in household storage containers had ...
The interception of aquifers during borehole heat exchangers installation may cause the contact of swelling or soluble layers with groundwater and trigger consequent hazardous phenomena. The transformation of anhydrite into gypsum is one of the well-known swelling phenomenon, characterized by an increase...
Among the well-established, proven, and reliable RTTs, heat pump (HP) technology is possibly the most versatile. When driven by electrical power and coupled to ground sources/sinks, it is definitely the most efficient one [8,9], since one unit of electrical power is required for the exchan...
5. Scale in Thermal Properties Measurement This paper has so far considered the features of different methods of small-scale laboratory testing for thermal properties (Section 3), as well as the procedures for carrying out and interpreting large-scale in situ thermal response tests (Section 4). ...
