摘要:

There are now nearly fifty schools in the UK which incorporate some means of using solar energy to reduce their purchased energy needs through the sole use of their form and fabric. These passive solar school buildings are described in this paper which reports the results of a detailed survey carried out by the authors.

摘要:

The purpose of this paper is to define a finite-time closed Brayton cycle and apply it to an indirect gas-cooled nuclear reactor plant for its optimization. Practical engineering heat engine power optimization usually takes the form of determining minimum heat exchanger area per unit net power output or minimum cost per unit power output, rather than determining the maximum cycle efficiency. The objective function of the optimization described in this paper is specific power, power output per total heat exchanger surface area. The specific power output of a real indirect gas-cooled nuclear reactor plant coupled with its heat source and sink is analyzed. It is found that there is an upper bound on the specific power output of the nuclear power plant. This bound can guide the evaluation of existing real plants or influence design of future power plants.

摘要:

A transient test method has been developed to determine the thermal performance parameters of solar collectors whose fluid heat capacities are very large. The experimental test procedure used is simple and the tests can be performed under a variety of environmental conditions ranging from highly variable to almost steady. Two solar collectors were tested using the method under varying environmental conditions, and satisfactory results were achieved. This is in fact the only test method available for such collectors.

摘要:

Energy is fundamental to our material wellbeing and this has always been the case. Today, in the richer countries, we want more of energy's fruits, to enable us to travel more; to heat, cool, and light more buildings; to communicate more. The hundreds of millions of people in the poorer countries need more just to improve their lot in life.
