Advanced Flat Plate Collectors

1987
The main drawback of the conventional flat plate collector is its inability to operate with reasonable collection efficiencies at temperature around 80 °C, thus limiting their applications largely for providing hot water and space heating. Therefore, the major concern of solar collector designers is the reduction of heat losses from the solar energy ...

Flat-Plate Collector Analysis

1984
The flat-plate solar collector is essentially a heat exchanger in which the radiant energy of the Sun is converted to low-grade thermal energy. The concept is not new as some of the earliest recorded examples of the use of flat-plate collectors occurred around a hundred years ago [4.1, 4.2].

Solar Flat-Plate Air Collectors

2016
A solar flat-plate air collector has the application of space heating and crop drying under forced mode of operation with air as a working fluid. For space heating, hot air can be stored in a rock bed for night-time application. The electrical power consumed under forced mode can be met by integrating a PV module into an air collector panel.

“Convective” flat plate collectors and their applications

Solar Energy, 1995
Abstract The “convective” flat plate collector is a particular two-way collector system with air in gravity flow as primary working fluid. Its thermal characteristics are described. Results of outdoor tests and thermal simulations are shown. Different applications of the system are presented: water heating, steam generation for medical sterilization,

Analysis of Boiling Flat-Plate Collectors

Journal of Solar Energy Engineering, 1986
A detailed model for use with TRNSYS, capable of modelling a wide range of boiling collector types, was used to analyze boiling flat-plate collector systems. This model can account for a subcooled liquid entering the collector, heat losses in the vapor and the liquid return line, pressure drops due to friction in the collector and piping, and pressure ...

Flat plate collector utilizability for Guyana

Renewable Energy, 1994
Abstract The objective of this study was to analyse one year of hourly solar radiation data from Georgetown, Guyana, and derive a simplified tool in the form of a utilizability curve for designing solar thermal systems with fixed flatplate collectors.

Calculation of flat-plate collector utilizability

Solar Energy, 1978
Abstract The “utilizability” or φ-curve method developed by Whillier [1] and later generalized by Liu and Jordan[2, 3], can be a very useful design tool for some types of solar energy systems which utilize conventional flat-plate solar collectors. The generalized φ-curve method in its original form, however, has several drawbacks.

Performance of a flat-plate solar collector

Solar Energy, 1967
Abstract The design of a simple solar collector made from corrugated, galvanized-iron sheet is given. Its performance during summer at Allahabad, India, at various flows is presented. To obtain hot water at temperatures higher than 170 deg F, temperature being averaged over an eight-hour period, a flow of only about 1 lb/hr-ft 2 should be allowed ...

Solar motors with flat-plate collectors

Solar Energy, 1966
Abstract Research at the Laboratory of Meteorological Physics of the University of Dakar has been devoted for several years to the study of solarenergy utilization. An experimental solar motor has been operating since August 1962. This motor drives a pump lifting 8 to 10 liters water per minute from a depth of 13 meters.

Flat-Plate and Evacuated Tube Collectors

2013
Solar-energy collectors are devices employed to gain useful heat energy from the incident solar radiation. They can be of the concentrating or the flat-plate type. A simple flat-plate solar energy collector consists basically of an absorbing surface which absorbs the insolation and transmit it in form of heat to a working fluid commonly air or water. A
