To protect pipelines from freezing, cold water pipelines are laid in common insulation with one or more pipelines that transport hot water ...
Calculation and adjustment of regulators, as well as the choice of optimal modes of operation of thermal engineering objects (mine calorifiers, boilers, boiler rooms, boiler houses, heat and water supply systems of mines, settlements and cities) are determined by the value of the atmospheric air temperature ...
To control inertial objects can be used a method of regulation based on the input of the process derivative, obtained as a pulse repetition rate, into the control action. ...
