“…Gives the experimental view of the entire three model, the design is suitable for flat as well as for inclined surfaces and ICS 2 shows the satisfactorily performance in respect to thermal and depth. The new trend in design is to use computational studies on the performance of ICSSWH [24][25]. The [26][27] uses the new material known as phase change material (PCM).…”

Energy is the significant need of the world either for nutrition or for development of the society. The power bank of the earth is the sun, which has tremendous amount of energy in it and will never exhaust. The conversion of solar energy to thermal energy is the function of collector. Flat plate collector (FPC) are cost effective and more convenience in all collectors. The paper reveals the different design of the flat collectors used to enhance the efficiency of the collector. Effect of using phase change material, nanofluids, heat pipe, different geometry of the tubes and absorber discussed. This review deals with the suggestion for the research work in flat plate collector. Keywords: FPC Design; Solar Collectors; different collectors for SWH; Design of SWH I. INTRODUCTIONEnergy is the most important and a key factor in day-to-day life. The keen interest is towards the solar energy which is a pure green energy and available in plenty. The energy of Sun used to heat the water, which is the great need of each human being for various purposes. During review it is found that the various solar water heating system were made by many researchers with relatively high efficiency and reasonable cost, but the system does not meet the requirement of other countries due to climatic conditions and many other reasons. Today environment is the major issue and the awareness regarding the environment is increasing this promote solar and renewable energy system in world and decreases the dependencies' on fossil fuels. The solar water heating system consist of riser tubes, absorbers a dark surface plate, insulation and glazed glass. The system when exposed to the sun, the absorber absorbs the solar radiation and transfers a part of it to the fluid flowing over/under it [3][4][5][6][7]. The more is the collector area more will be the energy, but the law of thermodynamics state that no machine can gives 100% output therefore we even cannot get the 100% percent conversion. Now, the design goals were to have the collector that can convert the maximum solar energy to heat energy with a lesser amount of losses; and cost. The objective for the review of solar water heating system is to get the various designs available and invented by researchers at one place to get the idea of possible development in it with the future of design in Solar Water Heater (SWH). The review is limited to the flat plate collector and other similar to it. There are two broad categories of SWH (passive and active), each of them operating in either direct or indirect mode. The active systems give 35%-80% efficiency higher than those of the passive systems [3].

“…The integrated solar collector is placed facing south with a latitude of 4.57º to capture optimum solar radiation but because of dust and rain water retention, it is advisable to tilt the solar collector 5º to 10º higher than its latitude [12,13]. In this experiment, 60 liters of water is poured into the tank to be circulated through the solar collector for 24 hours.…”

The availability of hot water is essential for overnight industrial and domestic use. Integrating the solar heater with thermal energy storage showed a promising result on hot water production when sunlight is not present. In the present work, an outdoor experimental investigation of a flat plate solar collector was carried out with PCM and nano-enhanced PCM. The phase change material (PCM) used in this experiment is paraffin wax. However, 1% weight fraction of 20nm copper nanoparticles was added to improve the properties of the compound. Three cases have been investigated, namely, without PCM, with PCM and with nanoenhanced PCM (nano-PCM). It was found that at the operational mode of 0.5 kg/min and at a 10º inclination angle, with PCM and nano-PCM, hot water at 40.2ºC and 40.8ºC was produced the following morning. However, without the PCM case hot water was produced at 35.2ºC. The system was enhanced by 6.9% and 8.4% respectively when PCM and nano-PCM were used.

“…Previous works on this subject include the study of flat plate solar energy collectors [23,24], polymer solar collectors [25,26], solar collectors with horizontally inclined absorber strips [27], and tilted wavy solar collectors [28] on integrated collector storage devices [29,30], among others. In all the aforementioned cases, the authors found good agreement between theoretical and/or experimental analysis of the collectors and the obtained CFD simulation results.…”

Assessment of the Use of Venetian Blinds as Solar Thermal Collectors in Double Skin Facades in Mediterranean Climates

Abstract:The global trend on energy integration and building efficiency is making both researchers and building developers look for technical solutions to use facade surfaces for energy harvesting. In this work, the assessment of the thermal performance of a double-skin facade (DSF) with a venetian blind-type of structure used as a solar thermal collector by means of computational fluid dynamics (CFD) is presented. A Venetian blind collector would allow for heat rejection/energy harvesting and exterior views simultaneously and can be easily integrated into the DSF aesthetical design. For the purposes of this study, the modeled facades (south, west, and east-oriented) were set to be located in Barcelona (Spain), where large solar gains are a constant condition throughout the year, and such large semi-transparent envelopes lead to interior over-heating in buildings, even during the winter. For the studied facades, both the reductions in radiative heat gains entering the building and the heat recovery in the Venetian blind collector were evaluated for a yearlong operation.
