THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

The Design and Analysis of Experiments

Solar Engineering Of Thermal Processes

Several simplified design procedures for solar energy systems require monthly average meteorological data. Monthly average daily totals of the solar radiation incident on a horizontal surface are available. However, radiation data on tilted surfaces, required by the design procedures, are generally not available. A simple method of estimating the average daily radiation for each calendar month on surfaces facing directly towards the equator has been presented by Liu and Jordan [1]. This method is verified with experimental measurements and extended to allow calculation of monthly average radiation on surfaces of a wide range of orientations.

Due to good matching between solar irradiation and cooling demand both in time and quantity, trying to make PV air conditioner independent from public grid so as to develop a stand-alone PV air conditioner is always a struggling objective for researchers and engineers. However, limited by the high cost of battery, it is a hard task to popularize stand-alone PV air conditioner among broader areas. In this paper, a strategy, which converts curtailed electricity of PV system into cooling storage as a backup for cooling demand, to reduce battery capacity for stand-alone PV air conditioner is proposed. To investigate the effect of this strategy, a stand-alone PV air conditioner with both battery and chilled water tank is built in TRNSYS. A fictive office building in Haikou is chosen to do case study. Through sizing work, the results show a reduction for battery capacity, which supports the application of this strategy.
