KẾT LUẬN

Tôi sử dụng hệ thống thông gió chéo và giảm nhiệt độ máy lạnh để tiết kiệm số tiền lớn cho hóa đơn điện. Hãy tham gia ngay để tiết kiệm chi phí và bảo vệ môi trường.

My home office, originally the master bedroom, is the worst room in my apartment for . It feels like the roof does nothing to keep the heat out during heatwaves.

Cross ventilation works because the wind creates a pressure differential outside your home. The upwind side of your home experiences high-pressure airflow, while the downwind side creates a low-pressure zone. The pressure differences exist whether or not your windows are open, so you might as well harness them.

By opening your windows, the high-pressure air has a more direct path to the low-pressure zone — it’s easier to flow through a home than around it. It’s a great way to bypass your home’s insulation, which prevents thermal energy from entering and exiting your home. Once your home is cool enough, closing the windows and curtains ensures the indoor air will warm more slowly.

If you want to use natural ventilation for cooling, the outside air must be colder than the indoor air.

For example, I close my windows and rely on my AC after the outdoor temperature tops 75ºF. This is usually when my thermostat kicks in — around 72ºF in my basement. I keep the windows closed during hot weather — unless the nighttime temperature drops below 70ºF before I head to bed.

Cross ventilation and air conditioning can coexist

According to Energy.gov’s Energy Saver office, the best candidates for natural ventilation are coastal and arid climates. On the coast, you can harness cool sea breezes to help make your home more comfortable.

While these regions are the most likely to experience huge nighttime temperature drops, you can also use wind ventilation in other places. It probably won’t be as effective, especially if your local climate is humid, but it’s still a good option for bringing in fresh air.

Unfortunately, the effectiveness of cross ventilation as a cooling method diminishes as the outside temperature rises. Keeping the windows open all day may eventually allow hot air to enter your home and strain your AC.

Likewise, poor air quality days aren’t great for open windows, so it’s worth setting up an alert if you live somewhere susceptible to air pollution.

Using a window fan to create cross ventilation is straightforward. The simplest method is exhaust ventilation, which uses a single fan that pushes air outdoors on the opposite side of the house from where you want the air to come in. This creates a negative pressure zone that pulls air through your home and out through the fan.

While this method is effective, it may not move air fast enough for a strong breeze, especially in large homes. Low air movement also means potential cooling effects can disappear into turbulence before reaching the out-blowing fan.

Fortunately, we can mostly overcome this by adding a second, in-blowing fan in the other window in a process called balanced ventilation. The in-blowing fan creates a high-pressure zone that more smoothly flows into the existing low-pressure zone.

Although I use a pair of Lasko box fans from Walmart, you can also buy purpose-built window fans, like this model from Bionaire, with reversible airflow, thermostats and extender screens for sealing windows.

Using smart home tech to control window fans

For this to work, you need a smart home hub capable of using temperature as an automation trigger. Your best bet is something like Home Assistant, SmartThings or Ezlo. Unfortunately, I couldn’t find this option on Alexa or Google Home with my current smart home devices. I can’t access Apple Home, so I can’t verify how it uses temperature in smart home routines.

Although window fans work well in my situation, you probably don’t need them if your home already handles cross breezes like a pro. Still, you can use smart home sensors to notify you when it’s time to close the windows and blinds for the day.

Fresh air ventilators

While window fans are probably best for renters and people on a budget, you can also outfit your home with a fresh air ventilator accessory for your HVAC system. Provided you have a compatible system, Ecobee smart thermostats support cross ventilation through their Free Cooling feature. You can also get similar functionality from whole-house ventilation products like AprilAire.

I have no experience with whole-house ventilation systems, so I recommend contacting a local HVAC installer if you want to add one to your home.
