Heating Design essays

Heating Design essays In this task we were asked to make a house that would be thermally efficient and thus energy efficient to heat and cool. Energy is transferred through three mediums, conduction surfaces contacting and transferring energy through them, convection natural air cycles etc, and radiation energy transferred without a medium. I have firstly focused on convection, pumping insulation into the walls and fiberglass roofing insulation as well as think underlay insulation underneath the think carpet. Reverse cycle air conditioning which provides the house with heating and cooling, ducts are placed in most rooms alongside reversible ceiling fans, using the fans air can be cycled around, and hot air can be recycled and cool air more effectively cool and heat rooms. In the roof there are tiles with a reflective foil underneath which helps to insulate and with fiberglass insulation in the ceiling, the roof cavity would then be a huge insulator so a large extracting fan is in the roof with a cover so in summer it can extract heat and in winter it can be covered to avoid heat loss. The windows are double-glazed which saves a lot of heat escaping or keeps the heat out. On the interior the windows have heavy curtains, which are lined to help insulate. In summer the west side of the house is receiving lots of sun light and energy because the sun is in that part of its cycle by the afternoon so the house heats up more in the afternoon in summer than any other time. Evergreen trees are placed to the west of the house and no windows so heat transfer is reduced on the west walls. On the south walls the windows are small and unobstructed. On the east, grass replaces concrete; grass does not reflect as well as concrete so it avoids heat reflection into the small windows, which I did not include because it is even more effective to have no east and no westerly facing windows. ...
