Energy demand information from each of the buildings analysis
Incoming article date: 06.03.2017We have reviewed several Russian cities masterplans between 2012 and 2016, a total of 4 plans focusing on two aspects – energy consumption and district heating networks. Where possible, load management and controls usage have been added to the study, but it should be noted that development on the cities shown on the plans is subject to uncertainty due to lack of load clarity. Self-acting controls have a sensor filled with a substance which changes its volume as the temperature changes. The volume change is transmitted through a capillary tube to an adjusting device placed on a control valve. The adjusting device contains a bellows, and when the bellows changes in volume - expands or contracts - this motion is transferred to the cone in the valve. Self-acting controls are well suited to keep the flow temperature of the domestic hot water or the ventilating air at a constant level. In heating systems, the secondary flow temperature is controlled according to the outdoor temperature via an electronic control station complete with a sensor a weather compensator. As a rule the control valve is placed on the primary side. The temperature on outgoing domestic hot water is controlled in the same way.
