A cooler air conditioner homemade is an economical and environmentally friendly way to combat hot weather. Several types of homemade air coolers are available for business buyers seeking innovative solutions to commercialize.
Fan and Ice Bowl
This is the simplest type of DIY air cooler. It requires only a desk fan and a bowl of ice. To make it, put ice cubes in a bowl and place the bowl in front of a desk or table fan. The fan will blow air over the ice, cooling it in the process. As a result, the fan will blow cool air into the room.
Cardboard Box Air Cooler
This design enhances the previous concept. An evaporative cooler works better using a fan and ice. A cardboard box, a small fan, and ice or frozen water bottles are required for the cooler. A larger cardboard box should surround a smaller one. Place a tub of ice or frozen water bottles inside the smaller box. After that, insert the small fan into the smaller box so that its front part faces the ice. Finally, place the entire setup inside a room. The fan will blow air over the ice, which will cool it. The cooler can be more effective by placing it near an exhaust fan that releases warm air outside.
Desktop USB Air Cooler
The USB air cooler is among the most advanced homemade air conditioners. It offers portability and convenience powered by a USB connection. This air conditioner requires a small cardboard box, a USB-powered computer fan, a micro USB connector, and ice or cold water.
Users should cut holes in the cardboard box. One hole should fit the size of the user fan, while another should fit the micro USB connector. Next, they should insert the fan into the hole so that its part sits inside the box. Then, they should add ice or cold water inside the box before connecting the USB to a power source.
Water Bottle Air Conditioner
This air conditioner cools air through evaporation. It uses a fan to blow air over a wet surface. The cooler needs a plastic water bottle, a small fan, a cardboard base, and water.
Users should cut the top part of the bottle and place the cardboard base on a flat surface. Next, they should place the water bottle on the base and fill it with water. Finally, they should insert the fan on the cardboard base so that its part faces the water bottle. The fan will blow air over the water bottle. The evaporation process will cool the air.
Size and Portability:
Homemade air coolers are available in different sizes. Portable models fit easily on tables or counters, while bigger versions can be floor-standing. A more compact homemade air conditioner cooler is likely to be more portable and take up less space in the home.
Power Supply:
Many homemade air coolers are now powered by electricity. Some versions have rechargeable batteries, while others need to be plugged into an electric socket. Older designs may use gas-powered engines instead of electrical power.
Cooling Method:
Different coolers work in various ways. Some use the evaporation of water to produce cool air, while others blow air over ice or ice packs. Others may blow air through wet sponges or rags. A more integrated version has fans pulling the air through a water-absorbing material like cellulose.
Fan:
The fan is an important part of a cooler's air circulation system. The fan speed determines the amount of air the cooler will circulate. Many coolers have fans that allow users to choose between normal, medium and high speeds. Bigger coolers tend to have fans with stronger power. The fan's motor and blade design ensure the fan operates efficiently, quietly and smoothly.
Water Reservoir:
The water reservoir stores the cool water that produces cool air. Reservoirs are made from strong plastic and come in different shapes and sizes. Hot climates generally require bigger reservoirs to last longer without refilling.
Filters:
Homemade air coolers have different types of filters. Many coolers have filters made of cellulose. Others may use fiberglass or HEPA filters. HEPA filters are preferable for people worried about airborne diseases or pollutants as they are more efficient at filtering out small particles.
Water Pump:
The water pump raises water from the reservoir to keep the cooling media wet. Submersible pumps are placed under the water, while external pumps are located outside the reservoir. The pump selected determines how long the cooler can run before needing water replenished.
Proper maintenance can extend the life of a homemade air conditioner cooler. Carry out the following simple periodic maintenance tasks:
Keep It Clean:
Regularly washing and cleaning the outside surfaces of an air cooler helps keep dirt and disgusting germs away from the unit. Users should wipe down the surfaces with a damp cloth and soapy water. Rinse thoroughly to remove any soapy residue that can damage the paint.
Change the Filter:
It is important to change the filter after a specified period or once it becomes not too clean. A dirty filter causes the cooler to work too hard to push air. It can also affect the air the unit blows out.
Check Water Level:
For water-based coolers to keep doing their job, the water level needs to be maintained. Daily or weekly checks should be done to ensure it does not get too low or dry.
A homemade air conditioner isn't limited to just being indoors. The beauty of a portable air conditioner is that it can be carried anywhere, making it possible to stay cool even in outdoor settings.
Camping trips:
On hot summer camping trips, a homemade portable air conditioner will come in very handy. Whether camping in the woods or at the beach, setting up the cooler AC inside the tent will create a comfortable sleeping environment.
Backyard:
When hanging out in the backyard on extremely hot days, a portable homemade air conditioner can provide instant relief from the heat. Positioning it close by while relaxing on the porch or patio will make it feel like an outdoor living room.
Outdoor events:
Whether attending a summer concert, sporting event, or festival, taking a portable air cooler will allow fans to beat the heat. Homemade portable air conditioners are a must for outdoor gatherings in high-temperature months.
Worksite:
For those who work outdoors, a portable air conditioner provides a cool space during breaks. It can also be used for indoor projects without air conditioning. Whether constructing, landscaping, or performing maintenance, having access to a homemade air cooler greatly improves comfort and safety at warm work sites.
Travel:
With its small size, the portable air conditioner allows cool travel adventures. On a road trip or while staying in budget motels, it provides affordable temporary air conditioning away from home.
Homemade air coolers are popular alternatives to air conditioners because they are less expensive and use less energy. When choosing a cooler, consider the size of the room and the unit, the temperature difference required, the humidity level, portability, noise level, and energy efficiency.
Room and cooler size
A small cooler placed in a large room will struggle to cool the air effectively. Similarly, a large cooler with a high air flow rate will be too powerful for a small room. Consider the recommended room dimensions provided by manufacturers, and compare them with your room size.
Required temperature difference
The performance ratings of coolers depend on the temperature difference between the cooler outlet and the ambient inlet. Indoor temperatures are usually lower than outdoor temperatures. Coolers placed outdoors tend to cooler much more than indoor coolers.
Relative humidity
The performance of a homemade air cooler is highly dependent on humidity levels. High humidity may reduce cooling performance, while lower humidity allows the cooler to work effectively. When placed in areas with low humidity, users should expect a significant drop in temperature.
Portability
Users who want to move the cooler from one room to another should consider the weight of the cooler. Light coolers like the evaporative air cooler are easy to carry around. However, heavy coolers will need castor wheels and a moving handle.
Noise level
Every cooler produces some level of noise. The level of noise generated will depend on the fan speed. Higher fan speeds move more air but produce more noise. Users have the option of selecting the cooler fan speed that suits their needs.
Energy efficiency
Air conditioners use a significant amount of energy. Choosing a cooler that uses less energy will lower electricity bills without sacrificing comfort. The energy consumption of coolers is much lower compared to air conditioners.
Q: Will a homemade air conditioner cool a room?
A: Probably not. A homemade air conditioner is unlikely to cool a room the way a conventional air conditioner does. It may create a breeze and make the room feel somewhat cooler, but it won't lower the temperature of the whole room.
Q: How much does it cost to make a homemade air conditioner?
A: The cost will vary depending on what materials are already on hand and what design is chosen. It could be anywhere from $20 to $100 or more.
Q: How long will a homemade air conditioner last?
A: If it's made using durable materials and it isn't exposed to extreme heat or weather, such as direct sunlight, then the homemade air conditioner could last a few months at least. Regularly changing the ice packs or water bottles should allow it to function longer. Any portable version that uses a fan, such as a cooler air conditioner homemade with a ventilation fan, will last longer than stationary versions.
Q: Is it worth making a homemade air conditioner?
A: If one lives in an area with frequent heat waves or temperatures high enough to pose a health risk, investing in a commercial air conditioner may be more practical. However, in emergencies when it's really hot and conventional air conditioners aren't available, a homemade air conditioner could provide some relief.
