例句與造句

1. Dynamic insulation is normally implemented in timber frame walls and in ceilings.
2. The temperature profiles through dynamic insulation taking into account the decrease in surface temperature with increasing air flow is shown in Fig 4.
3. However, dynamic insulation also requires mechanical ventilation with heat recovery ( MVHR ) in order to recover the heat in the exhaust air.
4. It is frequently stated that in dynamic insulation the outside air is being warmed up by heat that would be lost in any case.
5. Insulations such as polyurethane ( PUR ) boards, which due to their micro-structure, are not air permeable are not suitable for dynamic insulation.
6. It's difficult to find dynamic insulation in a sentence. 用dynamic insulation造句挺難的
7. Dynamic insulation would appear, therefore, to overcome the major disadvantage of airtight envelopes which is that the quality of the indoor air will deteriorate unless there is natural or mechanical ventilation.
8. The following explanation of dynamic insulation will, for simplicity, be set in the context of temperate or cold climates where the main energy use is for heating rather than cooling the building.
9. Dynamic insulation is thus able to achieve the dual function of reducing the heat loss through the walls and / or roof whilst at the same time supplying pre-warmed air to the indoor spaces.
10. The idealised 1D model of dynamic insulation provide a great deal of physical insight into the conductive and convective heat transfer processes which provides a means of testing the validity of the results of CFD calculations.
11. A more robust way of introducing dynamic insulation to a building that avoids the pressure variation around the building envelope is to make use of the fact that in a ventilated roof space the pressure is relatively uniform over the ceiling ( Fig 9 ).
12. Furthermore, just as simple 1D steady state heat flow is assumed in the calculation of the heat transmission coefficients ( U-values ) that are used in the design, approval and building energy performance rating of buildings so the simple 1D steady state model of dynamic insulation is adequate for designing and assessing the performance of a dynamically insulated building or element of the building.

14. Dynamic insulation works best with a good thickness of insulation so taking 200 mm of cellulose insulation ( k = 0.04 W / m 癈 ) the dynamic U value for an air flow of 0.31 mm / s is calculated using equation ( ) above to be 0.066 W / m 2 癈 . If a lower dynamic U-value is required then a material with lower air permeability than fibreboard would need to be selected for the air control layer, so that a higher air speed through the insulation at 10 Pa can be achieved.
