Automatic opening vents of greenhouses with their hands

Many gardeners put a lot of effort to get better yield of crops grown in the greenhouse. It is necessary to consider all. In this case there are no trifles. To ensure the optimum mode of ventilation, set the machine for opening the vents of the greenhouse.

What types of machines for opening the vents of greenhouses exist on the market? How to do to install such a device with their hands? Talk about it in detail.

The Need

A Machine for opening the vents of the greenhouse is quite a simple device. It gives its owners a lot of advantages. Maintenance of the greenhouse complex will be much easier.

For each culture it is important to withstand certain conditions. Automatic ventilation will create the most favorable microclimate inside the greenhouse for those plants that are grown there now. Properly mounted and well-designed ventilation system will not only increase productivity but also make life easier for owners of greenhouses. Because they do not require more carefully monitor the conditions inside it. In sale there are 4 main types of such devices, which are distinguished by the type of devices. To properly mount or make your own similar device, you should be familiar with the most common of them.

Electrical system

The automatic opening vents greenhouse automatically according to the type of functioning are divided into mechanical and electrical. Both species have their advantages and disadvantages. For example, an electric machine for automatic opening vents of the greenhouse responds to changes in temperature in the greenhouse or just working in timer mode. Now there are controllers that you can program and control using the Internet. The advantages of electric machines end opening, side vents for the greenhouse include the adaptability, compactness and efficiency. They have great power.

The Main drawback-the dependence on electricity. If the power to the machine fails, could kill all the plants. Therefore usually acquire a replacement unit. The repair of such devices are quite costly.

Mechanical types

There are three types of mechanisms for the greenhouse. Automatic opening vents horizontal or vertical can use the principle of linear expansion of metals under the influence of temperature. This bimetal system in the manufacture of which use two different metals. For such devices it is very difficult to define correctly the necessary level of heat in the greenhouse.

Quite simple to assemble the machine hydraulic system opening the vents of the greenhouse (for example, “darling-San” or “Will”). It is not dependent on electricity, does not emit odors. Instead, it creates comfort and comfort inside the greenhouse. The disadvantages of such systems include, sluggishness, high cost, and the temperature control only in the place of installation. The latter – pneumatic mechanisms. They are based on the principle of the account of thermal energy. They are the easiest way to do it yourself. They are quite bulky and depend on the pressure in the atmosphere, but their cost is low in absolute independence.

The Types of automatic ventilation

There are several ways by which you can organize automatic ventilation of greenhouses. This should be considered when creating the perfect conditions for plants inside the greenhouse. If the design is quite large, should be airing in 2 Windows that are next to each other. In the case when the greenhouse has an elongated shape, use a machine to open the end vents of the greenhouse. This through-blowing. Both doors open automatically.

You Can use the machine for air vents in the wall that have a special device. Windows at the same time are at different heights. The accurate ventilation systems use sensors of temperature and humidity. It is also possible to do it yourself.

Today popular automatic systems of ventilation of domestic producers. Their costs are lower overseas, and the functionality and quality did not concede.

Very popular among the vacationers automatic opening vents for greenhouses “darling-San”. It keeps the temperature inside the greenhouse on the mark +16 - +25 degrees. Used for vents weighing up to 7 kg. For a more powerful opening of doors and Windows products used “Outpar" (the gain on stock is 100 kg), «Moscow»(the flap is lifted up to a height of 40 cm), “Thermovent” (opening to 45 cm up). Some manufacturers have resorted to little tricks. For example, automatic opening of greenhouse vents “Will” is intended solely for the designs of this manufacturer.

The Machine with your hands

There are checked by experienced gardeners techniques that provide good ventilation of the greenhouse. The principle of operation of such devices is clear.

Automatic opening vents for greenhouses with their hands to make just enough. To do this, use a sealed metal container. It transfers heat from the heat of sun rays inside. There are air and liquid. Substance creates the pressure inside the containers during expansion. Thus, the fluid flows in a quart jar. Under its weight the window will fall. This is done through the unit, which transmits the force at the point of attachment of string. When inside the greenhouse will be cool enough, the process will stop and go in the opposite direction. For making system will need the minimum of resources.

Some secrets

Automatic opening vents for greenhouses with his own hands made in a specific pattern. To do this in pre-prepared containers (empty and sealed) is inserted into the tube. It is passed into the bowl the liquid, which should fill 40% of the internal volume. This can be water, antifreeze or spent engine oil. After filling of the container it tightly closed and fastened rigidly on the top rung of the greenhouse.

In a quart jar in the lid drilled a hole in which is inserted the tube. It is better that it is small. So there will be less liquid to evaporate subsequently. Through a tube filled with water or oil. The level should be 1 cm higher than the turn of the closed bottom hole of the tribe. Then fix the seam that connects the string of small containers and the correct point of the transom. Both containers are connected into a single system by means of a flexible hose.

Setup

A Machine for opening the vents of the greenhouse after installation, you must configure at normal temperature and closed the sash of the greenhouse. This procedure requires the use of the method of trial and error for the correct balance.

If the window is too heavy, the design should strengthen the weight of the jars. The ratio of the contained liquid does not change. If you find the right balance with the help of this method, you can open and rather cumbersome Windows. They will be closed under its own weight. The lower bar of the frame should be heavier than the top.

After Reviewing a device such as a machine for opening the vents of the greenhouse, you can purchase the most suitable option, or run a similar system with their hands. Considering all the conditions which are inherent in the particular greenhouse, you can create an ideal environment for the different types of crops.
