The performance parameters of a hybrid air-to-water solar heater has been presented in this paper for a cold climatic region in India. A conventional solar air heater in conjunction with an air-to-water heat exchanger of finned-shell-and-tube type in which hot air from the collector transfers...

The calculation of solar radiation received at a particular place and at a particular time, involves many factors like rotation and revolution of the earth, atmospheric attenuations, atmospheric conditions, time of day and year, geographic location of place, and site location of collector, tilt...

This paper presents a transient behaviour model for a single-glazed hot box type solar cooker which enables the temperatures of various elements of the cooker to be predicted. The experimental results conform well with the theoretically predicted values. In an attempt to establish a simple...

The temperature dependence of the overall heat-loss coefficient for flat-plate collectors has been studied by using stagnation measurements made with different configurations, viz., tilt 45 °s with single and double glazing and tilt 0 ° with single glazing. Comparisons have been made with...

The present investigation deals with a transient parametric analysis of a solar residential heating system which comprises a corrugated absorber water heater and a water-to-air heat exchanger-cum-heat storage unit integrated to a residential building to be heated. The heat exchanger-cum-heat...

This article describes the results of a simulation study of a forced-circulation solar hybrid domestic hot water system (SHDHW) that circulates air through a rockbed air heater and employs an external air-to-water, transverse fin, shell-and-tube heat exchanger to transfer heat from the air to...

The objective of this work is to assess the combined effects of fixed pressure drop and specific air mass flow rate on duct dimensions (length and depth) of single-pass-with-bare-plate, single-cover and double-cover solar air heaters, and to obtain the resultant system efficiency that...
