It was found that a lower design primary supply temperature of the district heating network would give a higher seasonal energy efficiency of the integrated system throughout the whole heating season.
Moreover, it was not always right to relate low design supply temperatures to high pump power consumptions and high heat losses in the district heating network, since the results showed that the seasonal pump power consumption and the heat loss would decrease with a lower design primary supply temperature.
PAGE A10 NEW SUPPLY ROUTE TO AFGHANISTAN A new route to take cargo to American and NATO forces in Afghanistan has opened, American officials said, providing an alternative to the primary supply route through the troubled border with Pakistan.
A new route to take cargo to American and NATO forces in Afghanistan has opened, American officials said Tuesday, providing an alternative to the primary supply route — through the troubled border with Pakistan — as it comes increasingly under threat.
To ensure the actual arrival of backup supply in cases of primary supply disruptions, a purchasing firm needs to work with its backup supplier to forge a strong partnership that not only protects itself, but also assures the backup supplier׳s economic benefit.
Although a regular diet is the primary supply of carnitine, endogenous synthesis is possible from sulphated amino acids (reviewed in [ 44]).
A number of state regulatory commissions are already wrestling with the issue, and California has a regulatory order on the table that would require utilities to deploy storage as a specific percentage of the grid's primary supply.
"It is a primary drinking supply for tens of thousands of residents," he said of the reservoir.
To achieve this goal, we have proposed an accurate simulation system in which a solar energy component serves as a primary load supply, and an energy recovery component is based on a fuel cell.
The revisions passed also require a backup water supply for sprinkler systems, so that if the primary supply is cut off, as happened on Sept. 11, 2001, at the World Trade Center towers, the sprinklers will still work.
