Specifiers can find a range of Quiet Mark-certified heat pumps on NBS Source. Here are some examples: CS5800i AW Heat Pump Outdoor Unit - Air to Water Heat Pump | Bosch Thermotechnology Ltd | NBS Source Grant Aerona³ 13kW R32 Inverter Driven Air Source Heat Pump | Grant Engineering (...
Another possible reason is that in a more drastic climate, consumers tend to resort to other cooling/heating appliances rather than window air conditioners such as central cooling/heating systems, heat pump, etc. Fig. 3: Heterogeneous effect of temperature in terms of cooling degree days (CDDs)...
and water depletion (which is more sensitive to the technology type than the heat source). Sorbent-based DACCS exhibits a lower environmental impact profile using biomethane for heat. The only increase compared to the heat pump derived heat is terrestrial acidification, which is mostly driven by t...
The use of biomass products, such as wood, is considered a renewable energy source, and likely to increase as Europe moves away from fossil fuels. There is a dearth of IAQ data in energy efficient homes using biomass burning stoves, despite the fact that wood logs have been shown to have...
all urban soils indicate that 2,4-D is highly mobile and more likely to leach from surface soil to groundwater. This movement could potentially impact drinking water quality, non-target organisms, and food safety. Additionally, 2,4-D from impermeable surfaces could serve as a direct source ...
Then, the source term can be expressed as: 𝑆=𝑃𝑀𝑜𝑢𝑡×𝑞𝑣×(1−𝐸𝑓)+𝑃𝑀𝑜𝑢𝑡×𝑝×𝑞𝑖S=PMout×qv×(1−Ef)+PMout×p×qi (9) Here, 𝑃𝑀𝑜𝑢𝑡PMout is the outdoor particle concentration in µg/m3, 𝐸𝑓Ef is the filter ...
simple static approach, using the annual share of each energy carrier on the overall electric mix and the individual PEF of each energy carrier. The electric mix of each of the six countries studied comes from the “energy statistical country datasheets” published by the open source EUROSTAT [...
Low-cost, open-source hardware such as Arduino or Raspberry Pi has found its way into the scientific community for quite some time [5]. This can be seen in the many scientific publications that make use of this technology [6,7,8,9,10,11,12,13]. For example, they are used in agricu...
Outdoor air pollution is the main source of PMs in offices [151], and PMs level can be harmful; for example, a Beijing office can reach a PM2.5 level of 100 μg/m3, while the limit recommended by the National Ambient Air Quality Standard (NAAQS) is 35 μg/m3 [152]. We have ...
in Section 1, there were no significant sources of air pollution in the immediate vicinity of the station; hence, it can be assumed that the levels of pollutants in the area of the station were largely due to their transportation to the place of measurement from more distant source areas. ...
