Sentences with phrase «preventing absorbed heat»

A greenhouse works primarily by preventing absorbed heat from leaving the structure through convection, i.e. sensible heat transport.

Not exact matches

The next most abundant gases — water vapor and carbon dioxide — do absorb a portion of the infrared heat radiated by the earth's surface, thereby preventing it from reaching space.

Unlike many tropical plants that close the pores on their leaves at midday to reduce sun exposure, mangroves remain active, absorbing heat to prevent evaporation of the shallow waters they depend on.

The friction creates a sort of slush that prevents heat propagation, much like the vibration dampers in a vehicle's shock absorbers.

That prevents the carbon layer from absorbing as much heat from the skin.

Ice crystals block the airflow, less heat is absorbed into the evaporator, more ice is formed, less airflow... The TXV bulb will radically drop in pressure as the evap temperature approaches freezing, and cause the TXV to completely shut off liquid refrigerant flow into the evaporator to prevent this condition.

To prevent the water from freezing, you can use dark bowls and leave them in a sunny spot to absorb the heat by day, as well as bowls that are deeper and wider.

One effect of this integrated water store is to inhibit the concrete from absorbing and storing heat in the first place — it's this absorbed heat that tends to prevent the concrete from cooling properly in the evening and at night.

If CO2 acts like a blanket, absorbing heat energy, and prevents the heat from escaping, is this different than CO2 stores heat?

Here are just some of the many benefits that these systems provide all at once: green infrastructure absorbs and sequesters atmospheric carbon dioxide (C02); filters air and water pollutants; stabilizes soil to prevent or reduce erosion; provides wildlife habitat; decreases solar heat gain; lowers the public cost of stormwater management infrastructure and provides flood control; and reduces energy usage through passive heating and cooling.

Green roofs help to prevent water - runoff and pollution problems — water feeds plants, instead of running into sewers — as well as heating and cooling problems, since the roofs absorb solar heat.

Whatever the average regional temperature, it's hotter in the cities, because concentrations of traffic, business, heating, cooking, lighting and air conditioning generate what has become known as the urban heat island effect: what makes this worse is that the asphalt, tarmacadam, stone, brick, glass and tile of which cities are made absorb radiation but prevent ground evaporation as a natural cooling device.

Houses in rainy regions might one day come with grassy rooftop gardens that absorb precipitation and prevent heat from within the house from escaping.

The heated air will rise, preventing the CO2 from re-emiting the energy it has absorbed to the surface.

A real greenhouse primarily restricts heat escape by preventing convection while the «greenhouse effect» heats the Earth because «greenhouse gases» (GHG) absorb outgoing radiative energy and re-emit some of it back towards Earth.
