'First, keep your windows, doors and blinds shut during the day to avoid hot sun beating down into your house. Then, during the evening, open your windows and place one fan facing out of your window, so it pushes the heat out,' they advise. 'Use a second fan, placed inwards, to circulate cool air into the room. '
Dirty air filter—A dirty filter restricts airflow, not letting your home get enough cool air. Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home.
Keep windows, blinds and curtains closed during the day to avoid letting any heat into your home. As soon as the sun goes down and the temperature starts to drop, open your windows and use two fans to cool the room down. Place one fan facing out of a window in order to push hot air outside.
The fan won't actually change the temperature of the room, it will just make it feel warmer. Be sure to turn it off when you aren't in the room to save energy. You only need your fan on the lowest setting to get the benefit. Any higher and you might actually feel colder.
A ceiling fan does not actually lower the overall temperature in a room, but it can definitely make a space feel cooler. Ceiling fans primarily work through something called a wind chill effect. Essentially, the moving air across your skin helps to evaporate sweat at a faster rate.
While evaporative cooling is cost effective and easy to use, it is not always the most effective solution. If you live in an extremely hot or humid climate, you might find more relief from the heat with an air conditioning unit. Air coolers work best in areas with a hot, dry climate.
Position a shallow bowl of ice, ice packs or a frozen hot water bottle behind your fan, and it will soon spread the cool temperatures around your room. Too keep cool at night, you can mimic this fan and ice technique with a small fan on your bedside table and a spray bottle of chilled water.
The basic idea is that the fan blows air over a very hot heat sink. Since the air is cooler than the heat sink, it just cools it off through conduction of heat. Actually, it would work even if you don't have a fan but the fan just makes it work more efficiently. Oh yes, fans are also used to circulate air in a room.
Place your fan so that it faces the opposite wall from where most of the activity takes place in your space. This approach will drive the air to the surface, where it will bounce off, mingling with the rest of the air and cooling the space.
Your sleeping environment and the bedding you sleep on are the most common reasons people get so hot when they sleep. This is because your core temperature drops a couple of degrees during the night and sheds heat into your surrounding environment.
Faulty Return Air Vents
So, if one room is always warmer than the rest of your home, the return air vents in the room could be blocked or damaged. When this occurs, cool air is blocked from coming through those vents in your floor or ceiling, resulting in a less comfortable space.
Simply switching the direction of your fan will actually push the warm air down from the ceiling, keeping your room warm (and saving you money on that energy bill). If saving money is your goal, you can simply turn down the thermostat and let the fan push down the warm air that's already in the house.
Hang a damp towel over an open window (as long as you are getting a breeze) to provide a cooler breeze. This will give a little relief but we have not found it as effective as the frozen washcloth in tip 1. Stick a bowl of ice water in front of your fan to help circulate the cooler air.
Okay, the basic idea is pretty simple – ice absorbs heat as it melts. If you blow warm air across ice with a fan, the air will be cooled as the ice melts. So, warm air goes in and out the other end you get cool air. That's how things should work in theory.
The reason your room is so hot can likely be attributed to something causing the conditioned air to be affected before it goes to the designated area. One of the main reasons for this is the presence of leaks in the air ducts feeding the room.
You might also consider fans, evaporative coolers, or heat pumps as your primary means of cooling. In addition, a combination of proper insulation, energy-efficient windows and doors, daylighting, shading, and ventilation will usually keep homes cool with a low amount of energy use in all but the hottest climates.
