Automatic machine for ventilation of greenhouses - a simple mechanism that facilitates life

A greenhouse for summer residents is no longer a luxury, but a necessity, especially for those who live in northern regions and zones of risky farming. Some lovers of growing vegetables and flowers are already happy owners of it, the rest are only going to buy or build themselves.

A person who lives in the city and arrives at the dacha only on weekends, it is difficult to control the temperature in the greenhouse. In addition, for optimal plant development, it is necessary to eliminate the greenhouse effect that occurs in greenhouses after irrigations under the influence of elevated temperatures. To cope with this will help ventilation, which also reduces the likelihood of plant diseases and prevents the reproduction of pests.

It is convenient and practical to install an automatic machine for ventilating greenhouses. It consists of a mechanism that ensures the opening of the window with a temperature rise in the greenhouse above 25 degrees and closing when the temperature is reduced to 16 degrees.

The machine for ventilation of greenhouses works without electricity and batteries. The mechanism is based on the principle of expanding the liquid in the thermocylinder and pushing the piston when heated. With a decrease in temperature, the liquid contracts, as a consequence, the piston drops, closing the window. As a working fluid, as a rule, oil is used.

The machine for ventilation of greenhouses is suitable for any design. It is not difficult to install it. However, do not forget about some points. The thermocylinder must be covered with a sun shield so that it is heated from the air in the greenhouse, and not from the sun's rays. Additional safety belts are desirable, fastened to the window, to protect against gusts of winds. To adjust this mechanism, you need to wait for the temperature in the greenhouse to be set at 25 degrees, and only then tighten a special nut on the end of the cylinder.

If there is a desire and ability, then you can make an automatic machine for airing the greenhouses. For example, from two meters of a metal pipe, a shock absorber from the rear door of the Zhiguli (suitable and non-working) and waste oil.

At present, the most popular and practical is the polycarbonate greenhouse, which has a number of advantages over glass. It creates the most favorable conditions for plants. Passing the sun's rays, refracts them at different angles, i.e. Plants receive illumination from different directions.

Cellular polycarbonate for greenhouses is much lighter than glass. It is shockproof, fireproof, resistant to ultraviolet radiation and extreme atmospheric influences. This polymer material is an excellent sound and heat insulator. When drilling, it does not break, it easily rolls into rolls and, importantly, it is much cheaper than other materials. Polycarbonate greenhouses are easier to transport and mount. They do not fog, do not change color, are able to withstand wind, hail and snow thickness. Will serve for many years without changing their qualities.

Polycarbonate greenhouse with a vending machine is the right solution to ensure that there are regular fresh vegetables on the table and beautiful flowers in the vases.
