Disclosed is a building system for reducing energy consumption. The building system includes an exterior wall layer disposed on an exterior wall of building walls, a circulation pipe disposed inside the exterior wall layer and through which a heating medium for absorbing heat caused by solar radiant energy applied to the exterior wall layer flows, and a thermal energy storage connected to the circulation pipe and configured to store the heat transmitted by the heating medium.

Building system for reducing energy consumption

The present disclosure is relates to a centrifugal turbo machine equipped with stretchable and variable diffuser vanes capable of securing further improvement of compression efficiency by reducing an angle of the vane and increasing a length of the vane using forced rotating driving of a diffuser during operation of a compressor so as to reduce frictional loss of the fluid when a flow rate of fluid is reduced.
