Keeping Cool At Home
It's Hot! How do you stay Cool?
The first step is always prevention, simply cover the windows during the day. Windows are always a compromise between energy efficiency and the basic desire for natural light. Hot outdoor temperatures are best controlled inside by blocking the heat and direct sunlight. In that sense, a room with no windows or small windows would be ideal. But nobody wants to live in a cave-like room. You can achieve the same effect by installing thermal curtains over the windows. At the very least, close the drapes or the blinds. Window blinds pulled down to cover windows and cool room. - If you need a fast solution, drape thick, soft materials like bedspreads or lightweight down comforters over the windows during the day when the heat is at its peak. The thicker, the better.
Open the windows at night- After the sun has set, temperatures outside usually will dip lower than temperatures inside. If this has happened, remove the covers from the windows and open the windows as far as possible. Letting in the air at night is good, but keeping the air moving is even better. If you have two windows that are in line with each other or even positioned diagonally, make sure that both are open.
Skip Using the Hot Appliances- Most appliances give off some residual heat. For the clothes dryer, consider substituting with an indoor drying rack. As for the oven, a microwave is a definite improvement, but even that generates some heat. Leave the cooking for another day and instead stay cool by exploring the possibility of delicious no-cook dinners. Shut off Incandescent Lights which produce a significant amount of heat, instead use cool CFL or LED lights.
Close Unused Rooms that you aren't using as they seriously impede your cooling efforts. By closing the door of unused bedrooms or by keeping the bathroom door always shut, you effectively trap that heat and keep it out of the way. However, before closing off a room, shut the curtains tight and even cover windows.
No AC? ; Use Fans to Cool a Room
In an article I read from the Connecticut State Office of Consumer Counsel, a portable or ceiling fan costs 50 times less to run than central air conditioning, plus no harmful refrigerant is required. Even if you do use ACs, fans can lower their overall cost by supplementing their operation or reducing the frequency of their use. As long as the outdoor temperature is less than the indoor temperature, a fan is effective and will cool down indoor heat.
- Move cool air into the house and hot air out simultaneously by creating a cross breeze. You'll need two fans and two windows that open.
- Position one fan at an open window so that it's blowing into the room.
- On the opposite side of the house, find another window that's in a straight line from the first window.
- Clear obstructions between the two windows (chairs, tables, etc.)
- Open the second window.
- Position the other fan near the second window so that the air is blowing out of the house.
- Turn on both fans.
The fan must be blowing from the outside to the inside. When the two temperature points reverse and it's warmer indoors than outdoors, turn the fan around so the air is blowing toward the outside.
- Even if you don't have two fans available, one fan can still create enough of a cross breeze to push out some of the hot air.3
- Open one window.
- Tightly close all other windows near the open window.
- Locate a second window on the other side of the home, in a straight line from the first window.
- Remove obstructions between the windows.
- Open the second window.
- Turn on the fan.ate a Cross Breeze With One Fan
- Even if you don't have two fans available, one fan can still create enough of a cross breeze to push out some of the hot air.
In the summer, you want to feel the air circulating underneath and around the area reached by the fan. On a hot day, you would feel more comfortable and can detect air circulation on the right setting. In winter, as hot air rises, it becomes trapped at the ceiling level. On the correct winter setting, the fan should push air up and draw that hot air down the side walls of the room. You would feel practically no air movement underneath and only a little air circulation closer to the walls. During summer, this setting does not provide any comfort or enough air circulation to the room. But it does bring the hot air down to warm the cooler air closer to the floor.
When It's Too Hot For a Fan Combine Fans With AC
Air conditioners incorporate two different coils to cool your home. The cooling compressor is set outside the home, separate from the fan unit used to blow the cool air throughout the home on the central air unit. The central air unit can cool the entire home evenly by using the existing heating and cooling ducts throughout the home. An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
The coil outside of your home is called the condensing coil. It consists of a compressor, condensing coil condenser fan, and a grill to protect persons from coming into contact with the fan blade, a case built around all of the components, controls, and two refrigerant lines that run into the home to the evaporator coil. A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.
The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser's metal tubing and fins. The refrigerant inside the compressor is pumped through the evaporator coil inside, which cools the air as the furnace fan blows air through the coil. The coil absorbs the heat from the air. Then the refrigerant flows back outside to the condenser coil, and this is where the heat that was absorbed is released. The refrigerant returns to a liquid form as it is cooled, and the cycle continues until the home reaches the desired temperature.
The two most common types of air conditioners are single room air conditioners and central air conditioners.
Improved environmental footprint: Overall home energy use is improved, which decreases your overall carbon footprint to the world at large.Better cooling performance: High-efficiency units cool down rooms faster than older models.
- Quieter operation: With better insulation and higher quality parts, high-efficiency air conditioners run considerably quieter.
- Better durability: Thanks to better materials and parts, these air conditioners typically last longer than non-efficient models.
- Flexible controls with "smart: features: ENERGY STAR® compliant window units must have “smarter” features, such as an energy-saving mode and automatic reminders to service the filters.
A central air system cools all the rooms connected to ducts at once, getting the home cooler quickly. However, it is the most expensive method of home cooling.
