The Direct Vent Solution from Nelson & Small offers a complete range of energy-saving direct vent heat and on-demand hot water systems for primary or supplemental use in the home, additions, second homes or vacation homes -- the most flexible, customizab
摘要: A forced draft direct vent system is provided for an indoor domestic type gas water heater having an atmospheric burner. The forced draft system permits adaptation of the water heater as a combined water heater and space heater in a compact continuous upright arrangement of components....
For example, the extremely high density of IT equipment in data centers requires year-round cooling in most cases, whereas IT equipment in office buildings displaces a portion of the heating load. The efficiency of the HVAC system also has a major impact on the energy expended to meet the ...
sedimentsare generally thoroughly bioturbated, as are hemipelagic muds. Microbial processes are important in controlling the chemistry of seawater and in the development of authigenic pelagic sediments. Coral reefs and both cold and hot vent communities create large biogenic rock masses in deep water...

The flue or vent system has a dual-chambered construction in a balanced flue stove. One chamber draws fresh air from the outside into the stove for combustion. At the same time, the other expels the combustion gases back outside. This closed-loop system eliminates the need for a ...
19), it is impossible to determine which flow(s) came from the same vent system during a single eruption. As illustrated by the Fissure 20 lava flow, the relationship between channel geometry and emplaced lava volume may not, therefore, be as straightforward as has been inferred to date for...
