Keep Cool When It’s Hot Outside
这里有一些在室外炎热的时候节约能源和金钱的方法!
- Close outside doors, 当你白天不在家的时候，窗户、百叶窗或窗帘, especially on the east and west sides. 如果安全的话，在晚上或早上打开窗户，让凉爽的空气进来.
- Avoid producing heat inside during the hottest part of the day. Do laundry, run the dishwasher, etc., in the early morning and late evening hours when it’s cooler. 用高压锅或慢炖锅代替烤箱.
- 试着用冷水澡来降温，而不是给整个房子降温.
- 考虑安装一个全屋风扇，在晚上将室外较冷的空气吸入室内，这样你就可以关掉空调了。.
- Plant deciduous trees or install awnings to shade your home, especially on the south and west sides of your house. Before planting trees, 确保它们长到最大尺寸时不会干扰输电线. Refer to our Tree Planning Guide for more information.
- Consider installing a ceiling fan in frequently used rooms. Moving air can make you feel up to four degrees cooler. Ceiling fans are helpful in homes both with and without A/C.
- 当你要长时间外出时，关掉空调.
Central A/CSelecting and Installing Central A/C
- If your A/C needs ongoing, expensive repairs, or if it is more than 15 years old, you should consider buying a new one. 一个新的高效装置，如果尺寸和安装得当，将会降低运行成本.
- If you want to reduce your operating costs, 寻找具有高季节性能源效率比(SEER)的空调。. 在我们的服务区域，由于夏天很短，家庭空调的投资回收期可能很长.
- 购买合适尺寸的设备并正确安装对提高效率和舒适度至关重要. 中央空调必须由持牌暖通空调承包商进行尺寸、安装和设置.
- For the highest efficiency, 考虑为室外风机和压缩机以及室内空气处理器购买变速电机的空调. 这些可变容量的空调是最有效的，也可以提供更高的舒适性，降低噪音. 这些系统通常更昂贵，而且由于我们的夏天很短，回收期也很长.
- Ask a professional to inspect your duct system. Leaky, 不绝缘或破损的管道系统很常见，会降低中央空调和供暖系统的效率.
A/C Maintenance
- Routinely check your system’s filter during the cooling season. Replace (or clean if reusable) as needed. 肮脏的过滤器阻挡了正常的气流，大大降低了系统的效率和寿命.
- 如果您遇到问题，请让专业人员对您的空调进行维修. Ask for a tune-up that includes a check of the refrigerant charge, cleaning of the coils and an inspection of your duct system.
Everyday A/C Tips
- Don’t crank the temperature down to try to cool your house faster. It will not cool your home any faster.
- Check your thermostat setting. Most people can be comfortable between 74-78 degrees.
- 考虑安装一个可编程的恒温器，以便在夜间和外出时自动调节更高的温度，而不会牺牲你需要的舒适度.
- 天气条门和嵌缝的窗户，以防止失去凉爽的空气到外面和温暖的空气进来.
- 确保你的房子有足够的隔热材料来帮助散热.
Selecting and Installing Window Room A/C
- Shop for an ENERGY STAR certified unit. 能源之星认证的窗户房间空调比目前最低规定效率的机型至少节省10%的能源，比旧机型少得多.
- For optimal operation, 将本机安装在您想要降温的房间朝北的窗户上, or in a shaded area.
- Consider a unit with controls, such as a digital readout for the thermostat setting and a built-in timer; both can help your unit use less energy. 一些设备将能够通过Alexa、谷歌或类似的东西进行控制.
- Bigger is not always better. 购买一个太大的单位效率较低，因为增加了开/关循环. Use the following chart to determine the size you need. For room A/C units, size is measured in British thermal units (BTU), an indication of cooling capacity.
AREA TO BE COOLED
(SQUARE FEET) |
CAPACITY NEEDED
(BTUS PER HOUR) |
| 100 – 150 |
5,000 |
| 150 – 250 |
6,000 |
| 250 – 300 |

| 700 – 1,000 |

Make adjustments for the following circumstances:
- If the room is heavily shaded, reduce the capacity by 10%.
- If the room is very sunny, increase the capacity by 10%.
- 如果经常有2人以上入住，则每人增加600btu.
- If the unit is used in a kitchen, increase capacity by 4,000 BTUs.
Window Room A/C Maintenance
- Clean filter monthly when in use. Wash foam filters with soap and water and air dry.
- Vacuum the coil fins.
Everyday Window Room A/C Tips
- 如果你希望回家后房间凉爽，在空调上安装一个计时器. 检查看定时器是额定的安培和电压的单位.
Selecting and Installing a Ceiling Fan
- 能源之星认证的吊扇/灯组合单元比传统的风扇/灯单元效率高60%. Savings come mostly from the lighting on the fan, so if your fan doesn’t include lighting, be sure to purchase an ENERGY STAR certified light kit.
- For summer and winter savings, 买一个可逆的风扇，夏天会产生向下的气流，冬天会反过来使天花板附近的温暖空气循环.
- 安装时，风扇叶片离地面至少7英尺, one foot below the ceiling and two feet from the nearest wall.
- 在选择吊扇时要考虑房间的大小和叶片的大小. Multiple fans may be needed in rooms longer than 18 feet.
Everyday Tips for Ceiling Fans
- Switch the fan and light off when you leave the room. Fans don’t cool rooms — they cool people. When circulating air passes over your skin, it picks up evaporating moisture, making you feel up to 4 degrees cooler.
- If your ceiling fan has a reversible motor, 在冬季的几个月里，将风扇反转以产生温和的上升气流, which forces warm air near the ceiling down into the room.
Selecting and Installing an Evaporative Cooler
- 选择一个有两个或三个鼓风机速度和一个自动打开和关闭冷却器的恒温器.
- 蒸发冷却器的尺寸没有空调的尺寸那么重要. 建议的指导方针是每平方英尺冷却面积每分钟3立方英尺(CFM)的气流.
- 将蒸发冷却器放置在没有室外障碍物的地方, vents or combustion appliances. Make sure you can plumb a water supply pipe to it.
Evaporative Cooler Maintenance
- 你的冷却器一年要保养两次——一次在降温季节之前，一次在夏天.
- Have the unit professionally winterized before the winter season.
Everyday Tips for Your Evaporative Cooler
- Evaporative coolers can cool outdoor air by about 15 to 20 degrees. The lower the humidity, the more effective the cooling is. 来自蒸发冷却器的冷却空气会增加你家里的湿度.
- 在操作蒸发冷却器时，至少要打开一扇窗户. 较冷的空气将随着气流进入房间，并将现有的空气推到外面.
- During moderate temperatures ( 85 degrees or lower), 只需使用蒸发冷却器风扇将室外较冷的空气吸入家中，而无需使用冷却介质来冷却空气.
- 预计将使用大约三分之一的电力来运行一个类似容量的空调. 然而，你的冷却器每天将使用3到15加仑的水.
