Abstract: Comparisons of the compression ratios, efficiencies, and work of the ideal Otto and Diesel cycles are presented at conditions that yield maximum work per cycle. The compression ratios that ...

Abstract: The thermal performance of six solar domestic hot water systems and a conventional hot water system have been carefully monitored by the National Bureau of Standards in Gaithersburg, Maryland. ...

Abstract: A rating procedure for solar domestic hot water systems is described which combines the advantages of short-term system tests and correlations of long-term thermal performance. The testing procedure ...

Abstract: An analytical method is developed for estimating R , the ratio of the long-term monthly-average daily radiation on an inclined surface to that on a horizontal surface. This method differs from ...

Abstract: This paper investigates the effect of heat exchanger allocation on overall system performance using both reverse Carnot and vapor compression refrigeration cycle models to calculate system performance ...

Abstract: This paper presents an analysis of the multi-stage Rankine cycle aiming at optimizing the power output from low-temperature heat sources such as geothermal or waste heat. A design methodology ...

Abstract: A computationally simple algorithm is presented for evaluating the hourly utilizability function, φ, defined as the fraction of the long-term, monthly-average, hourly solar radiation incident on ...

Abstract: Although the performance of solar domestic hot water (SDHW) systems has been well studied, there are several promising control alternatives that have not been thoroughly investigated. Reduced ...
