Participation reward: 3 Wealth. Reward for correct answer: 10 wealth. A certain industrial building is 15 m in height. The calculated total heat loss of the building’s envelope during winter heating is 1500 kW. The heat transfer coefficient of the exterior windows is 3.5 W/(m2·K). What should be the heat loss due to cold air infiltration? ( ) (A) 375kW (B) 450kW (C) 525kW (D) 600kW New activities have started in the production area; the prizes are attractive, so hurry and participate: 【Producing Through Summer】The production area has entered the \"train during the hot summer days\" mode
Answer: B. Analysis: According to D.0.4 of the Warmth Code, the heat loss due to cold air entering indoor spaces through gaps in doors and windows in industrial buildings can be estimated using Table D.0.4. The thermal coefficient of the exterior window is 3.5 W/(m2·K). According to clause 2.2.6 of the \"Technical Measures,\" this is a double-glazed window; therefore, cold air infiltration accounts for 30% of the total heat loss, and the amount of cold air infiltration is 1500*0.3=450 Kw
What should the heat loss due to cold air infiltration be? (c
Answer: B. Analysis: According to D.0.4 of the Warmth Code, the heat loss due to cold air entering indoor spaces through gaps in doors and windows in industrial buildings can be estimated using Table D.0.4. The heat transfer coefficient of the exterior window is 3.5 W/(m2·K). According to clause 2.2.6 of the \"Technical Measures,\" this is a double-glazed window; therefore, cold air infiltration accounts for 30% of the total heat loss, with the amount of cold air infiltration being 1500*0.3 = 450 Kw
Analysis of B 450kW: According to Clause D.0.4 of the Thermal Code, the heat loss due to cold air entering industrial buildings through gaps in doors and windows can be estimated using Table D.0.4. The heat transfer coefficient of the exterior window is 3.5 W/(m2·K). According to clause 2.2.6 of the \"Technical Measures,\" this is a double-glazed window; therefore, cold air infiltration accounts for 30% of the total heat loss, with the amount of cold air infiltration being 1500*0.3 = 450 Kw
Answer: B. Analysis: According to D.0.4 of the Warmth Code, the heat loss due to cold air entering indoor spaces through gaps in doors and windows in industrial buildings can be estimated using Table D.0.4. The heat transfer coefficient of the exterior window is 3.5 W/(m2•K). According to clause 2.2.6 of the \"Technical Measures,\" this is a double-glazed window; therefore, cold air infiltration accounts for 30% of the total heat loss, with the amount of cold air infiltration being 1500*0.3 = 450 Kw.
