Five different SOFC system designs are evaluated in terms of their energetic performance and suitability for meeting residential thermal-to-electric ratios.
The results show high combined heat and power efficiencies for both cases, with higher thermal-to-electric ratio and lower electric efficiency for the hydrogen-fuelled cases.
The method is able to simulate bubble motion in liquid metal under magnetic field irrespective of high density ratio and electric conductivity ratio.
Then the chiller capacity and economic evaluation index value corresponding to each typical building with various ice storage rates and electric price ratios under three control strategies (chiller priority, storage priority, and optimizing) are calculated.
To find the optimum prime mover (among the gas engine, diesel engine and gas turbine) and its benefit in different load demands, two non-dimensional design parameters named electric cooling ratio and nominal power ratio are defined.
The goal of this study is comparison of a new operational strategy named variable electric cooling ratio (VER) with constant electric cooling ratio (CER) for different climates including hot, cold and moderate.
Gas engine nominal capacity, nominal capacity of TES and CES tanks, electric cooling ratio and operational strategies of electrical and absorption chillers as well as the engine at each hour were considered as 52 design parameters.
The ice storage rate and electric price ratio are introduced to denote the various ice storage capacities and the different electric tariff structures, respectively.
In addition, the range of its lever lengths is achieved according to the motor torque and speed characteristics and the electric power ratio characteristic.
While the optimal ice storage rate under storage priority control strategy will appear when electric price ratio is greater than 3.
The mesoscopic metallic ring is regarded as a "pure" inductance design, and the dependence of the quasienergy spectrum on a parameter called the electric matching ratio is presented.
