When calculating the heat loss caused by cold air entering the room through gaps in doors and windows, which of the following statements are incorrect? The correct answers are AC. (A) When determining the amount of cold air infiltration in multi-story residential buildings, it is possible to ignore the increase in outdoor wind speed with height; only the infiltration rate caused by the combined effect of thermal pressure and wind pressure needs to be considered. (B) When determining the cold air infiltration rate in high-rise residential buildings, both the combined effect of thermal pressure and wind pressure as well as the increase in outdoor wind speed with height must be taken into account. (C) The heat loss due to cold air entering the building through gaps in doors and windows can be estimated based on factors such as the building’s height, glass windows, and the overall thermal properties of the building’s envelope. (D) In the case of balcony doors in residential buildings, the heat loss resulting from cold air entering through these gaps should be calculated; the additional heat loss associated with the exterior doors should not be included in the total heat loss for those doors
When calculating the heat loss due to cold air entering the room through gaps in doors and windows, which of the following statements are incorrect? I choose AC. (A) For multi-story residential buildings, the amount of cold air infiltration can be determined by ignoring the increase in outdoor wind speed with height; only the infiltration caused by the combined effect of thermal pressure and wind pressure needs to be considered. (B) For high-rise residential buildings, the amount of cold air infiltration must take into account the combined effect of thermal pressure and wind pressure, as well as the increase in outdoor wind speed with height. (C) The heat loss due to cold air entering the building through gaps in doors and windows can be estimated based on factors such as the building’s height, glass windows, and the overall thermal properties of the building’s envelope.
