To maintain a comfortable indoor temperature in hot weather, people invented the air conditioner. Unfortunately, industrial devices are not cheap, besides, when buying a factory device, there is a risk that most of the time it will only take up space, collecting dust inside the unit. A budget air conditioner with your own hands will not be more effective than a factory one, but one of the options for homemade devices will improve the microclimate of a small room. In most cases, you will need the usual materials found in every home.
Air conditioner made of plastic bottles and fan
A do-it-yourself air conditioner made from plastic bottles does not take up much space in the room. It's easy to assemble and doesn't need to buy anything - just a fan.
For the most primitive but working conditioner, take 4-8 plastic bottles of mineral water or soda. Fill the containers with water, place in the freezer. After the water freezes, tie the bottles to the protective cover of your home desktop fan.
The rotating blades will disperse the cold air emanating from the frozen vessels. To prevent the water from melting too quickly, add regular table salt to it before freezing.
For a long cooling process, prepare 8-9 bottles, some of which will be stored in the refrigerator, and some will be placed on the fan.
The easiest option is to use wet gauze. Hang it over open windows and in front of a fan. With natural ventilation, moisture will evaporate and spread throughout the room. The rotating blades will support the process. This method is especially effective for dealing with stuffiness at night.
Desktop Fan Mini Air Conditioner
The device will need a copper tube, two pieces of plastic or rubber hose corresponding to the diameter of the tube, and several plastic clamps. All of these are sold in a car parts store. It is better to use a soft annealed tube with a diameter of 8-10 mm.
Try to neatly roll the tube into a spiral so that there is a gap of several millimeters between the turns, and make the total size of the entire "heat exchanger" of the air conditioner approximately equal to the diameter of the blades. Bring the inlet and outlet of the spiral tube out, put pieces of a thin hose at the ends.
If there is a sink or washbasin nearby, connect running water to one end of the pipe of the homemade air conditioner, and drain the other for draining, for example, into the sink.
Attach the entire structure to the fan guard using plastic clamps. Turn on the water and fan. The coolness from the constantly circulating water will dissipate around the room.
This method is suitable, for example, for the kitchen. However, if the tap is too far away, it may be difficult to conduct running water. Besides, the counters make the air conditioner too expensive.
The second method is the same design with a copper tube, only any container with water will act as a source of moisture for the air conditioner. The pump for the home aquarium will be responsible for the circulation of liquid through the system.
Connect the pump to one end of the copper tube, put a hose on the other end and lower it into the same container from where the water will be pumped. Moisture from the container will be driven through the copper tube of the air conditioner and returned back.
If the test run is successful, add ice to the bucket for best performance.
Cooling device from a container of water
A small tabletop air conditioner will come out of a plastic container that can be found in any home.
To overclock the air in the air conditioner, you can use a computer fan from an old system unit. The principle remains unchanged. Put ice and water in a container. The fan will help the evaporated liquid circulate through the house. If the container is long enough, cut holes in the cover for two fans. You can fasten them with bolts or self-tapping screws.
Such a model of air conditioner will not cool the whole room, but if you put it on the desktop, the effect will be.
How to make an air conditioner from a radiator
You will need a Zhiguli or Volga car radiator, a 12 Volt car fan, a fan frame (casing) for installation, a 12 V electric auto pump. You also need rubber tubes that are installed on the radiator, clamps for them and a sealant. A computer power supply is suitable as a current source.
The radiator is needed the simplest one without automation, you need to make a bracket for it. During the assembly of the air conditioner, the radiator is installed vertically. The hole for the thermal sensor is closed with a plug or a piece of a plugged tube.
Arrange the water supply from the bottom, and the return flow from the top. An additional tap is required to remove air locks, otherwise the air conditioner will operate with low efficiency.
Power is taken from the computer's power supply. Fasten the fan together with the casing to the radiator, the pump will drive water through the entire air conditioner circuit. Assemble a bracket that will be mounted on a bucket of water or other container. Condensation formed on the surface of the radiator will drain into the same bucket.
When working in one room, the temperature drops by 4-5 degrees. The main thing is to close the door to the kitchen and bathroom more tightly, it is from there that the streams of warm air come.
Do-it-yourself air conditioner from the refrigerator
For the assembly of the air conditioner, a small cabin radiator for the stove from a passenger car - 12 Volts, new or used, is suitable. You will also need a car washer reservoir pump or an aquarium pump, hoses, wires and any available 12V power source, such as a PC or laptop power supply.
The fan must be placed on the lid; a radiator will be attached immediately behind it. Make a bracket out of plastic that will hold both elements, and install it on the cover with bolts. In addition to self-tapping screws, it is recommended to use various adhesives and sealants for attaching fans.
Pour ice into the finished container (using a cold accumulator would not be the worst option), pour water, lower the pump or pump. Do not forget about fixing the rubber hoses of the air conditioner with clamps.
If you want to create a universal design of an air conditioner for a home and a car, make an adapter for a cigarette lighter, the car network has a voltage of 12V.
Spray humidifier
Such devices increase air humidity, so it makes sense to use them in dry climates. If the air humidity is already high, the spray conditioner will only make the situation worse.
For assembly, you will need a fan and a case, for example, a plastic bucket with a lid. Construct the simplest air intake device, for which use plastic plumbing taps or bottles, depending on the type of fan.
The principle of operation consists in taking air from the outside using a fan and forcing it into the evaporation chamber.Passing through the water, the air stream is cooled and exits. Insert the fan into the air inlet so that it draws in the external air flow and directs it inside the air conditioner container.
The outlet pipe will be a spray gun with the ability to regulate the flow.
From time to time it is necessary to add water to the conditioner tank. At low humidity and average fan power, the liquid consumption will be about 1 l / hour, therefore, it is recommended to use a bucket or container with a lid as a container.
Corrugated air conditioner
The simplest practical method is to make a fixture using an aluminum corrugated pipe and an exhaust fan. All this can be found in large construction supermarkets or in the market. It is advisable to take a powerful fan for the air conditioner in order to achieve the best result.
Dock the pipe with the cooler, aluminum stretches well and keeps its shape. Wrap with tape and place on a stand above floor level. Lift the end of the corrugated pipe of the air conditioner above the floor.
Pour water directly into the pipe. Spread the rags in it so that the water is absorbed: about 1/3 to 1/2 of the rags and water in relation to the diameter of the pipe.
After turning on the air conditioner, there is a decrease in the outlet temperature, in comparison with the inlet temperature, by 4-5 degrees.
If ice can be used, the cooling effect of the conditioner will be even better.
The biggest disadvantage of the design is that it takes up quite a lot of space, moving around the room is not very convenient. To prevent water from spilling out and the structure of the air conditioner to be stable, make a frame out of plywood.
Thus, to create an air conditioner with your own hands at home, you will need several primitive tools and materials, most of which can be purchased at car dealerships and construction markets. All of the above designs have many options for solutions and the potential for modernization.
