Energy efficiency indicator based on entropy production evaluation

The article is about one of the estimation methods of thermal objects energy efficiency. The method is based on entropy production ratio. The basic concepts of energy efficiency evaluation are briefly described. Entropy production ratio of heating building is obtained. This ratio called entropy efficiency can be used for heating building thermal efficiency. It is proved that thermal inertia of building depends on its entropy efficiency. The method is adapted for direct and reversed thermal cycles. The research results in universal indicator applying for any thermal systems, those not performing work including.
