摘要:

AbstractAn analysis of wind data for the ten‐year period 1979–1988 in Nigeria is presented. Surface and upper winds were considered as well as maximum gusts. The need for the provision of new data stations in order to enable a complete and reliable assessment of the overall wind power potential of the country is identified and specific locations suggested. Socioeconomic and political factors affecting the development of wind energy development in Nigeria are also discus

摘要:

AbstractThe annual heating and cooling potential of an underground air‐pipe system has been evaluated in terms of dimensionless parameters of the system. The effect of diurnal and annual variations of environmental parameters (solar radiation, ambient temperature and relative humidity) has been considered. The results are obtained for hot—dry, cold—dry and composite climatic conditions typified by the Jodhpur, Leh and Delhi climates respectively. The effect of suitable earth surface treatments on the thermal performances of the air‐pipe system has also been analysed.For wet—shaded earth surface the cooling potential of a pipe of length 50 m and radius 10 cm at a depth 6 m in Jodhpur climate is found to be 4472 kW h, while for the Leh climate under glazed and blackened earth surface conditions the heating potential of such an air‐pipe system is found to b

摘要:

AbstractAfter a discussion of heat losses and energy costs in municipal heated swimming pools, an analysis in presented of the performance of all of such pools in Northern Ireland. It is demonstrated that performance is generally well below that expected by the designers and reasons are identified as to why this should be so. The causes for poor performance are found to arise variously through poor design, inappropriate equipment selection and installation and bad control and operating practice. Part of the value of this study lies in the fact that as all pools in the region were included, with no pre‐selection, the findings can be expected to be fairly representative of such installations throughout the United Kingdo

摘要:

AbstractThe design of refrigeration‐based heat recovery systems for municipal swimming pools is discussed and the performance of all such pools in Northern Ireland is analysed. It is found that most systems are incorrectly designed and specified, that the operating conditions are usually sub‐optimal and that the control systems are normally either inappropriate or non‐existent. It is clear that heat‐pump based swimming pool heat recovery systems are not understood by either the designers, the equipment suppliers, the installers or the op
