Many summer residents make a lot of efforts to get the best crop of crops grown in the greenhouse. To do this, consider everything. There are no trifles in this business. To ensure the optimal ventilation mode, an automatic machine is installed to open the window of the greenhouse. It will facilitate the work of farmers, as it will relieve them of constant control of the level of humidity and temperature inside the greenhouse. What types of automatic machines for opening a greenhouse window are available? How to do, install a similar device with your own hands? We’ll talk about this in more detail.
Need for application
An automatic machine for opening a greenhouse window is a fairly simple device. It gives its owners a lot of advantages. Maintenance of the greenhouse complex will be much easier.
It is important for each culture to withstand certain conditions. Automatic ventilation will allow you to create the most favorable microclimate inside the greenhouse specifically for those plants that are now grown in it. A properly installed and well-designed ventilation system will not only increase productivity, but also make life easier for the owners of the greenhouse. After all, they no longer need to carefully monitor the conditions inside it. On sale there are 4 main types of similar devices, which are distinguished by the type of devices. In order to properly mount or make such a device yourself, you need to familiarize yourself with the most common of them.
Electrical system
Automatic machines for opening greenhouse vents in an automatic mode according to the type of functioning are divided into mechanical and electrical. Both varieties have advantages and disadvantages. For example, an automatic machine for automatically opening greenhouse vents reacts to temperature changes in a greenhouse or simply works in timer mode. Nowadays there are such regulators that can be programmed and controlled via the Internet. The advantages of electric automatic opening of the end, side windows for the greenhouse include technological effectiveness, compactness and efficiency. They have great power.
The main disadvantage is the dependence on electricity. If a power failure occurs, all plants may die. Therefore, a spare power unit is usually purchased. Also, repair of such devices is quite expensive.
Mechanical views
There are three types of mechanisms for the greenhouse. A horizontal or vertical window opener can use the principle of linear expansion of metals under the influence of temperature. These are bimetallic systems in the manufacture of which two different metals are used. For such devices, it is very difficult to set the correct level of heat in the greenhouse.
It is quite simple to assemble an automatic machine for the hydraulic opening system of the greenhouse window (for example, "Dusya-San" or "Will"). It does not depend on electricity, does not emit odors. Instead, it creates coziness and comfort inside the greenhouse. The disadvantages of such systems include a large inertia, high cost, and temperature control only at the installation site. The last variety is pneumatic mechanisms. They are based on the principle of accounting for thermal energy. They are easiest to do on their own. They are rather bulky and depend on the pressure in the atmosphere, but their cost is the lowest with absolute non-volatility.
Types of organization of automatic ventilation
There are several ways in which you can organize the automatic ventilation of a greenhouse. This must be taken into account when creating ideal conditions for plants inside the greenhouse. If the structure is quite large, you should ventilate through 2 vents that are next to each other. In the case when the greenhouse has an elongated shape, an automatic machine is used to open the end window of the greenhouse. This is through blowing. Both wings open automatically.
You can use the machine for window vents in the wall, which have special devices. The windows are at different heights. The most accurate ventilation systems use temperature and humidity sensors. It is also possible to do it yourself.
Manufacturers Overview
Today, automatic ventilation systems of a domestic manufacturer are very popular. Their cost is lower than foreign, and the functionality and quality are not inferior to them.
Very popular among summer residents is the automatic opening window for greenhouses "Dusya-San." It maintains the temperature inside the greenhouse at around +16 - +25 degrees. It is used for window leaves weighing up to 7 kg. For a more powerful opening of doors and windows, Ufopar products are used (the gain on the stem reaches 100 kg), Tuymazy (the leaf rises to a height of 40 cm), Thermovent (opening up to 45 cm up). Some manufacturers have resorted to a little trick. For example, the “Volya” greenhouse window opener is designed exclusively for constructions of this manufacturer. This should be considered when purchasing such a product.
DIY machine
There are methods proven by experienced summer residents to ensure high-quality ventilation of the greenhouse. The principle of operation of such devices is understandable.
Do-it-yourself automatic machine for opening window leaves for greenhouses is quite simple. For this, a sealed metal container is used. It transfers heat from heating by the sun's rays inward. There are air and liquid. The substance creates pressure inside the container during expansion. Thus, the liquid flows into a liter jar. Under its weight, the window will fall. This procedure takes place through a block that transfers force at the point of attachment of the twine. When the inside of the greenhouse becomes cool enough, the process will stop and go in the opposite direction. A system will require a minimum of resources.
Few secrets
Do-it-yourself automatic window opener for greenhouses is made according to a certain scheme. To do this, a tube is inserted into a previously prepared container (empty and sealed). Through it, liquid is transferred to the vessel, which should fill 40% of the internal volume. It can be water, antifreeze or used engine oil. After filling the tank, it is tightly closed and fixed firmly on the upper crossbar of the greenhouse.
In a liter can, a hole is drilled in the lid into which the tube is inserted. It’s better to be small. So the liquid will evaporate less subsequently. Water or oil is poured through the tube. The level should be 1 cm higher than the border of the blocked lower hole of the tribe. Then the seam is fixed, connecting the small container with the string and the correctly selected transom point. Both tanks are connected into a single system using a flexible hose.
Customization
The machine for opening the greenhouse window after installation should be set up at normal temperature and the greenhouse sash closed. Here, the procedure requires the use of trial and error for the right balance.
If the window is too heavy, then the design should be strengthened by the weight of the jar. The ratio of the poured liquid does not change. If you choose the right balance, using this method you can open rather bulky vents. They will close under their own weight. For this, the lower block of the frame must be heavier than the upper.
Having familiarized yourself with such a device as an automatic machine for opening a greenhouse window, you can purchase the most suitable option or do a similar system with your own hands. Given all the conditions that are inherent in a particular greenhouse, you can create ideal conditions for a wide variety of crop types.
