The economics of an active solar heating system
The American University of Armenia recently installed a shower system in the ground floor of its building. In this note we examine the economic viability of using an active solar system to heat the showers. Using conventional discounted cash flow analysis as well as two other economic assessments of the capital investment, we demonstrate that it is economically justifiable to invest in a solar ...

Effect of window type, size and orientation on the total energy demand for a building in Indian climatic conditions
Windows in a building allow daylight to enter a building space but simultaneously they also result in heat gains and losses affecting energy balance. This requires an optimisation of window area from the point of view of total energy demand viz., for lighting and cooling/heating. This paper is devoted to this kind of study for Indian climatic conditions, which are characterised by six climatic ...

Energy and exergy analysis of a solar–assisted heat pump space heating system for clear days
The studies over solar–assisted heat pump systems have been performed mostly on time periods when solar radiation is high. Therefore, this study focuses on performance analysis of a solar–assisted heat pump system which stores the energy during the clear day and uses it as a heat source of heat pump space heating system during the night. Energy and exergy analyses divided into two parts, which ...

Energy and exergy analysis of a double–pass thermoelectric solar air collector
Analysis of energy and exergy has been performed for a double–pass thermoelectric (TE) solar air collector. The incident solar radiation heats up the absorber plate so that a temperature difference is created between the thermoelectric modules that generate a direct current. Only a small part of the absorbed solar radiation is converted to electricity, while the rest increases the ...

Environmental thermodynamic limitations on global human population
This paper examines, from a thermodynamic point of view, how many people the Earth can support. The maximum human population allowed by the natural earth ranges from 300 million millions to 1,700 million millions and will not exceed 1,300 million millions if an ambient temperature of 300 K is accepted. A further increase in population number is obtained for macro-engineered earth when heat pumps ...
