![عکس صفحه اول مقاله: Combined heat and power unit capacity for high-heat to power ratio buildings without selling excess electricity to the grid Combined heat and power unit capacity for high-heat to power ratio buildings without selling excess electricity to the grid](/preview/png/1733890.png)
This study presents a simple approach to estimate the capacity of combined heat and power (CHP) units suitable for installation in high heat-to-power ratio (HPR) buildings when excess electricity cannot be sold back to the grid. The two different methods used in this approach, a graphical method and a simple equation, are capable of predicting the optimum capacity to within 7% and 15%, respectively, of the methods presented in previous studies. In particular, the simple equation has the advantage of selecting the optimum capacity using the base and peak of the demand power load. The two easy-to-use methods can be used with any building, region, and energy-price structure that satisfies the conditions considered in this study, and will be of great use to future CHP owners.
► We developed a simple and general method of estimating the capacity of a CHP unit.
► It is suitable for high- HPR buildings when excess electricity cannot be sold back.
► The method is classified into a graphical method and a simple equation.
► The graphical method is applied when power load distribution is available.
► The simple equation is applied when base and peak power load are available.
