SUBSTANCE: method is implemented through the use of locking-regulating devices, equipped with motorised valves with gravity drives, in the form of a hollow torus, filled with vapors of low-boiling liquid (eg, carbon dioxide, freon, etc.). When reduction of the temperature the low-boiling liquid is condensed, the liquid is formed, which, flowing down to one side of the torus, changes the position of the center of gravity of the valve with respect to its axis of rotation, which leads to the closure of the valve. When the temperature increases the low-boiling liquid evaporates, the center of gravity returns back to the original location, the valve opens under the influence of gravitational forces.
