10 Easy Steps on How to Cool a Room With No Window

Step 1. DIY Air Conditioner:

This is one of the quickest and most cost-effective ways to cool down a room without the use of windows. To make your own DIY air conditioner, all you need is an old fan, some ice cubes, and a container with a lid or plastic bag.

Place the fan on one side of the room and fill up the container or plastic bag with ice cubes. Then place it in front of the fan so that the breeze will blow over it and create a cooling effect throughout the entire space.

Step 2. Pillows:

Pillows are great at retaining cold air for longer periods of time than other materials, making them perfect for keeping your room cool without having to open any windows. Simply fill two pillows with ice packs or ice cubes and place them around the room for a refreshing chill.

Step 3. Paper Towels:

A simple way to cool down your home without windows is to use paper towels. Soak some in cold water and hang them around the room, or lay them on top of warm surfaces like furniture or carpets, allowing the chilled material to transfer its temperature into the air.

For extra cooling power, you can also add a few drops of essential oils such as lavender, eucalyptus, or peppermint for an aromatherapeutic experience.

Step 4. Aluminum Foil:

The same goes with aluminum foil – soak it in cold water and hang it up around the room for a quick burst of coolness. The semi-reflective material will also help keep the sunlight out, preventing your room from becoming too hot. You can also use the foil to cover any exposed windows and doors, creating an extra layer of insulation.

Step 5. Fans:

Fans are a great way to create air circulation and keep your home cool without having any windows. You can use a traditional fan or go for something more modern, like an oscillating tower fan, which is designed to spread the breeze throughout an entire room. If you have a ceiling fan in your room, make sure to turn it on to the lowest setting for maximum cooling power.

Step 6. Ice Cubes:

Another easy way to bring down the temperature in your room without any windows is by using ice cubes. Place several of them around the area, such as on countertops, shelves, tables, etc., and allow them to melt slowly over time for a refreshing chill. As an added bonus, the evaporating water can also help to keep the air more humid, making it feel even cooler.

Step 7. Close the Doors:

Make sure to close all the doors in your home, as this will help to keep any warm air from entering the space and further cool it down. Additionally, by closing the blinds or curtains, you’ll be able to block out most of the sunlight that can contribute to a higher temperature inside. This simple step can make a huge difference when it comes to keeping your room cool without any windows.

Step 8. Create an Inlet and Outlet:

If you have access to an outdoor area, such as a balcony or patio, create an inlet and outlet in order to increase airflow throughout your home. Place fans on either side of the door for maximum efficiency – one fan should blow cool air into your room while the other fan should push hot air out. Ensure that the fans are set to the highest setting and leave them running for a few hours each day.

Step 9. Add Plants:

Not only do plants help to purify the air and make your home look more beautiful, but they can also cool it down by releasing moisture into the atmosphere. Choose plants such as spider plants or cacti for their ability to absorb heat and create a more comfortable environment without any windows.

Step 10. Invest in Insulated Curtains:

Insulated curtains are great at keeping the hot air outside while trapping cool air inside – ideal for those living in a home with no windows. Not only will these help to keep your room temperature regulated, but they’ll also block out most of the sunlight that can cause your space to become too warm.

By following these steps, you’ll be able to cool down your room with no windows in no time! With a few simple hacks and some extra materials, you can make your home more comfortable and enjoyable without having to resort to opening any windows.

5 Additional Tips and Tricks

1. Use fans to circulate air. If the room has no window, fans can effectively circulate air and make it feel cooler. Place the fan near a door or window opening so it pulls in cool air from outside.

2. Cover windows with thick curtains or blinds. Window coverings are a great way to keep out direct sunlight and hold in cold air during the night. Choose heavy fabrics like blackout curtains that will insulate your home against heat loss.

3. Install an evaporative cooler. An evaporative cooler is a device that uses water evaporation to cool down air as it passes through them, making them ideal for use in rooms without windows or external ventilation outlets.

4. Take advantage of thermoelectric cooling. Thermoelectric cooling is a technology that uses the Seebeck effect to generate electricity by converting temperature differences between two objects. This technique can be used to cool rooms without windows, as it produces no noise and requires minimal energy usage.

5. Utilize reflective paint or film on walls and ceilings. By reflecting heat away from the room, this type of paint or window film can reduce temperatures in the summer months while also providing additional insulation during colder months. If possible, opt for a light-colored finish that will reflect more sunlight than darker finishes.

In summary, if you find yourself stuck in a room with no window, these five tips and tricks can help you keep cool and comfortable even when Mother Nature throws you a curveball. From installing fans to utilizing thermoelectric cooling, there are plenty of creative solutions for keeping the temperature down in any space!

5 Things You Should Avoid

1. Keeping the room closed Don’t use electric heaters or other sources of heat, as this will make the room even hotter. Leave windows and doors open whenever possible to let in fresh air and cool down your space.

Don't Use Electric Heaters

2. Exposing too much sun: Don’t leave curtains or blinds open during the hottest parts of the day, as direct sunlight can quickly overheat any space. Close curtains at night to trap in cold air and limit exposure to daytime rays when possible.

3. Ignoring insulation: Make sure any gaps between walls, windows, and ceilings are sealed off properly with insulation material that is designed for that purpose. This will help keep temperatures low during warm weather months and cold air from escaping in colder months.

4. Not taking advantage of natural cooling options: Try to find ways to take advantage of natural cooling options, such as breezes from open windows and doors or fans and air-conditioners.

5. Overlooking other simple solutions: Keep some ice in front of a fan on a regular basis, use cold water bottles as DIY air conditioners, and even create your own DIY swamp cooler using empty containers filled with ice water! 

These little tricks can help you keep your room cool in the summer heat.
