Based on termotsilindr in which liquid greatly expands or shrinks depending on the temperature.

In the sun, the temperature increases in a hothouse, termotsilindr located there in is heated, the fluid pushes the piston and the piston, in turn, opens the window.

At sunset and a decrease in temperature in the greenhouse in termotsilindre fluid is compressed, and the ventilator closes under its own weight.

Thus pane rises to 45 centimeters.
