Towards smart cities: Integrating ground source heat pump systems with energy piles Human civilization is currently evolving at an unprecedented rate, with new breakthroughs every single day. This has become possible due to never-tapped-before levels of energy resources. ...
The results of the dynamic calculation demonstrate that installing a HVAC system with heat pumps in a brand new building will substantially reduce the end use energy demand and assist in achieving net zero energy performance. Although increasing building envelope thermal resistance will further reduce ...
A full performance exhaust system for the Nissan Skyline R34 GT-R can hypothetically yield an additional 25 hp. Two cast turbo outlet pipes can cost around $1,000, along with an equal-length downpipe that can set you back by $700. Installing a de-cat pipe might entail a price tag of...
8c: The interaction of globe valve design parameters to the liquid sound emission The CONVAL software looks at plant parameters (pipework, pipe devices, flow meters and valves) from an overall point of view with expert system features to compensate for the nega- tive trends described above. ...
October 20, 2015 by scienceofdoom Budischak et al (2013) is a very interesting paper (and free). Here is the question they pose: What would the electric system look like if based primarily on renewable energy sources whose output varies with weather and sunlight? Today’s electric system ...
However, the proposed control increased the CO2 emissions of the hybrid GSHP system due to the higher CO2 emissions from district heating. Keywords: hybrid ground source heat pump; district heating; borehole free cooling; cost-effective control...
However, in this energy harvesting, it is difficult to get the maximum power when nonlinearities are added into the system [15]. The main application of this technology is in telecommunication, radiometry, lighting, and heating. Radiant heat transmission is deadly [16]. The electromagnetic ...
Table 1. Costs of fire protection installation for variant I. The value of the above works will amount to EUR 759,494.85. The disadvantage of this variant is the high labour intensity of installing the sprinkler system, as well as the long waiting time for fire pumps, which can range fro...
A major problem of the Arduino platform is that the user must build the system by himself. Moreover, one has to write the proper software as well. Arduino platforms do not have specific interfaces to couple sensors. For that reason, it is necessary to include a data logger shield that ...
The gating system is responsible for leading the molten metal from the ladle to the mould cavity, ensuring smooth, uniform and complete filling while avoiding turbulence of the fluid, mould erosion, shrinkage, porosity and metal oxidation. Due to the complexity of the system, this step is ...
