Fed by the earth's natural, abundant, and readily available heat
, geothermal is able to provide clean, reliable, renewable energy 24/7, rain or shine, all year round, which is vital for consumers, businesses and industries in all sectors.
The available heat
sustains them through the night even if it means sitting around the small bonfire.
Figure 1 shows the share of used available heat
on the x-axis at corresponding temperatures on the y-axis.
The model has the choice of an open cab or closed cab with available heat
and air conditioning.
When naturally available heat
sinks were used (ground heat exchanger, GHEX, and crawl-space, CS), this effect became more pronounced, as in FC_GHEX and AC_CS.
Another readily available heat
source is solar energy.
Meanwhile, Kenics Static Mixer technology exclusively offers the highest available heat
transfer coefficients for fast, uniform heat transfer.
The infrared hot plate is the only currently available heat
stimulation method comparable to moxibustion.
After the completion of the original project, experimental data were obtained from a study which performed laboratory testing of three commercially available heat
pump water heaters, one of which our EES model was based on (BPA 2011).
Measures ranged from solar-panelled roofs being used to generate free daytime electricity, double glazed windows and secure doors reducing draughts, improvements to boilers increasing available heat
and external wall insulation.
Although various standards and methods exist to measure the efficiency of residential heating appliances, efficiency has generally been defined as the percentage of available heat
that is put into the home divided by the available heat
content of the fuel (Houck and Eagle 2006).
