Recovery is the recycling of already used air using a special device. This process can significantly reduce energy costs. The air recuperator is a very useful device that has certain advantages and performs several functions depending on the season.
Device of the device
So, the presented device has the following advantages:
- efficiency (an air recuperator consumes much less energy than an air conditioner);
- high efficiency;
- small size (it all depends on your needs), for industrial use you can choose large models;
- possibility of application in private and apartment buildings with centralized ventilation;
- the ability to use the device in winter (to heat the air) and in summer (to cool it), while no additional energy sources are required;
- low cost;
- the possibility of self-construction of the unit;
- the heat exchanger provides both inflow and outflowair, that is, you get additional natural ventilation of the room;
- good hygiene performance.
Varieties of recuperators
Today, the electrical goods market can offer a large number of device models from which you can choose the right device. So, there are such types of recuperators:
- rotary;
- roof;
- water recirculation;
- lamellar.
What materials are needed to make the machine?
If you want to make an air recuperator for your home with your own hands, then first you need to collect the necessary materials and tools. It should be noted right away that you will not need any expensive accessories. You can build a structure from improvised materials.
So, you will need:
- sheet metal of small thickness (can be galvanized);
- strips of technical cork (for frame);
- neutral sealant;
- MDF (for the construction of the body of the apparatus). For the same purpose, you can use a regular tin box of a given size;
- pipe flanges.
Of course, you also need to prepare tools: scissors for cutting metal, screwdrivers and bolts with nuts, self-tapping screws or other fasteners.
Device manufacturing technology
From this article you can learn how plate air recuperators are made. They arethe easiest to use and manufacture. In addition, the raw materials that will be used in the work are of low cost. So, all actions must be performed in a certain sequence:
1. First of all, you should decide on the dimensions of the device, since it depends on what width and length the plates will have. Before starting work, it is advisable to make a drawing of the apparatus on paper and make all the necessary calculations in advance.
2. Now let's start cutting the plates. The standard dimensions of each element are 2030 cm. If there is no metal at your disposal, you can use textolite or cellular polycarbonate. Please note that all sides of the plates must be perfectly even, so do not rush during the cutting process. If scissors do not do this procedure correctly, then use an electric jigsaw with a hacksaw. In this case, the edges do not need to be leveled.
3. Next, a frame is made that will be installed between the plates. The thickness of such a structure should not exceed 3 mm. Please note that small gaps (about 4 mm) should be left between the plates.
4. At this stage, the air recuperator can be fully assembled. To secure the elements, use a neutral-type sealant, as only it will not contribute to rust and corrosion of the metal. After the fixer is completely dry, place the device in the prepared case. Please note that for more efficient operation of the device, the inner surface of the box walls must be lined with insulation (mainlymineral wool).
5. It is imperative to drill holes in the housing into which flanges will be inserted to connect the device to the air ducts. All cracks must be treated with silicone sealant.
Helpful tips
Now you know how to build an air recuperator with your own hands. However, it must also be used correctly. For example, a plate-based device may freeze if the air temperature drops below 10 degrees. In order for this problem to be easily corrected, try to install a special sensor inside the unit that will record pressure drops.
In order to isolate the noise of the operating device as much as possible, attach fiberglass or mineral wool inside the box. These are all the features of the manufacture and use of the presented devices. Good luck!
