How to Cool a Small Room With No Windows

What Will You Need?

Before you start, make sure that you have the following materials on hand:

  • Curtains or blinds
  • Fans
  • Ice packs
  • Room dehumidifier
  • Portable air conditioner
  • Cooling sheets or fabrics for upholstery

Once you’ve gathered all the necessary materials, you can start on these simple steps to keep your small room with no windows cool.

10 Easy Steps on How to Cool a Small Room With No Windows

Step 1. Curtains or Blinds:

Hang curtains or blinds in front of your walls. The fabric material is important here as certain types, such as cotton, are more breathable than others (like velvet). Additionally, make sure that the color and design of the curtain fit into the aesthetic of your room. If possible, choose lighter colors as they reflect away from heat.

Step 1. Fans:

Place several fans around your room to keep it constantly circulating. This will help reduce the temperature significantly by keeping warm and cool air out. Be sure to periodically check the fans to ensure they are in good working condition.

Step 2. Ice Packs:

Place ice packs or frozen bottles of water around your room and in front of the fan to create a refreshing breeze. This is one of the most effective ways how to cool a small room with no windows, as it soaks up the heat from your area almost instantly. As an added bonus, the melted water from the ice packs will also help keep your room humidified.

Step 3. Room Dehumidifier:

Investing in a room dehumidifier can help you reduce humidity levels, resulting in cooler air temperatures inside your space. Some models even come equipped with built-in fans, which will provide an additional cooling effect for your windowless area. This is a great option for those looking for a more permanent solution.

Step 4. Portable Air Conditioner:

If you want a more powerful cooling effect, consider investing in a portable air conditioner. Make sure that the model is designed for small rooms and has plenty of vents for proper circulation. Don’t forget to check the power cords and plug points as well.

Step 5. Cooling Sheets or Fabrics for Upholstery:

Opt for fabrics like linen, cotton, and muslin when picking out your sheets and upholstery material. They are lightweight materials that breathe well and make it easier to keep cool even during hot summer days. Additionally, if you’re looking for extra insulation, try layering with thin blankets, as they can help trap cool air inside your room.

Step 6. Open Windows:

If you can access windows in nearby rooms, open them up as much as possible. This will help create cross ventilation that can cool off your room quickly. Moreover, it can also help reduce humidity levels, making your space feel even cooler.

Step 7. Place a Wet Towel:

Place wet towels around the perimeter of your room and in front of any fans that you have set up. The evaporation process will help cool down the air in your space significantly. Try to refresh the towels every few hours for the best results.

Step 8. Choose Appropriate Lighting:

When setting up lights, opt for LED bulbs instead of incandescent ones, as they generate less heat and produce brighter illumination with lower wattage levels. Additionally, if you are using lamps during nighttime hours, make sure that they are positioned so that the light is directed downward. Certain lightbulbs come with built-in fans for extra cooling power.

Step 9. Place Reflective Objects:

Positioning reflective objects such as mirrors or tin foil around your room can help reflect heat away from your space and create a more comfortable environment for you to relax in. Be careful not to place them too close to any fans, as they could create a fire hazard. If possible, ensure they are properly mounted onto the walls or ceiling.

Step 10. Do Not Use Appliances:

Avoid using any appliances which generate heat, as this will add to the temperature of your room and make it feel even hotter than before. This includes computers, televisions, and other electronic devices. Remember, the less heat your room produces, the cooler it will be.

By following these simple steps on cooling a small room with no windows, you’ll rest easy knowing that you have created an optimal breathing space for yourself! So don’t wait any longer and transform your windowless area into a cool, comfortable oasis.

5 Additional Tips and Tricks

1. If your room has no windows, investing in portable air conditioners is a good idea. These are great for cooling small spaces and will help you keep the temperature comfortable.

2. Place a bowl of ice in front of an electric fan or place damp cloths strategically to create cooling airflows that will reduce the temperature in your room.

3. Open any interior doors and close off adjacent rooms to contain cool air when possible.

4. Utilizing ceiling fans can also be helpful, as they circulate air throughout the room, which helps to even out hot spots and create a feeling of cooler temperatures overall.

5. Ensure your windows are properly sealed with weather stripping to prevent warm outside air from entering your home and raising the temperature inside your small room without windows.

Following these tips can help you stay cool without having access to open windows in your small room. With the right strategies, you can keep your space comfortable even during the hot summer months.

5 Things You Should Avoid

1. Don’t place a fan directly in front of an open window; this will draw the warmer air into your room and make it even hotter.

2. Avoid over-cooling, as having temperatures that are too cold can be just as uncomfortable as having temperatures that are too hot.

3. Refrain from using electric space heaters or other heating appliances, as these will cause the temperature to increase even further.

4. Steer clear of leaving lights on in the room if you’re trying to cool it down since they give off heat and raise the indoor temperature significantly.

5. Don’t block any vents or fans that may provide airflow to the room since this can prevent cooling air from entering and make it even warmer.

By avoiding these practices, you can ensure that your room will stay cool and 

comfortable all summer long.

How Can I Cool My Room Naturally?

1. For natural cooling, try setting up a mister or sprinkler near an open window so that the cool air from outside can be drawn in and circulated throughout your room.

2. Using natural ventilation by opening windows on opposite sides of the room to help create cross-breezes can also help cool down your space naturally.

3. Keeping your blinds and curtains closed during the day will help block out any direct sunlight and keep the temperature in your small room with no windows at a comfortable level.

4. Planting trees around your home can provide shade during the hot summer months, reducing solar radiation and creating cooler temperatures inside and outdoors.

5. Installing awnings over your windows or placing the reflective film on them can also help reduce the amount of heat entering through the glass.
