บ้านร้อน ถ้าติดพัดลมดูดอากาศ(พอ)ช่วยได้ ช่วยได้แค่ไหนไปดูกัน

The reason for using a non-ducted exhaust fan is to allow the cooled air to circulate through the attic ceiling before being drawn outside the house. This prevents the attic space from becoming overheated. The primary purpose of this system is to provide ventilation, not to remove odors or moisture (it actually helps with ventilation as a byproduct of installation). However, if you intend to install an exhaust fan to remove moisture (in a bathroom), you must connect the exhaust pipe directly to the outside of the building. Otherwise, the absorbed moisture could damage materials within the attic space.
