Performance analysis of a Copper Indium Gallium Selenide (CIGS) based Photovoltaic Thermal (PV/T) water collector

Abstract

This paper intended to investigate the performance of Copper Indium Gallium Selenide (CIGS) based Photovoltaic Thermal (PV/T) water collector under different operating condition. A CIGS photovoltaic with nominal power 65 W combined with an unglazed flat plate solar thermal water collector with effective area of 2 m was investigated. The performance was tested under different mass flow rates of flowing water which are 0.005 kg/s, 0.020 kg/s and 0.030 kg/s. For the mass flow rate of 0.030 kg/s, data was taken at different Peak Sun Hour (PSH) condition from 4.2 to 5.7. It was found that both electrical and thermal efficiency increased when the mass flow rate increased. Both electrical and thermal performance increased at the higher mass flow rate with the most efficient flow rate was 0.030 kg/s. The highest electrical and thermal efficiency was 4% and 23% respectively. In addition, when PSH increased, the electrical and thermal efficiency increased. However, at the PSH of 5.7 both efficiency slightly decreased. Further study on higher mass flow rate is necessary as the performance is not always proportional with mass flow rate. In this paper the value of the PSH was only limited to 4 points, which need to be further investigated for more values to clarify the correlation with the PV/T performance.

Parametric Assessment of The Thermal Performance of Coal-Fired Power Plant

“…However, exergy analysis has gained importance recently over the first law of analysis due to the failure of the first law of analysis to provide enough results that will aid studying the performance of power plants. Exergy analysis primarily aims at identifying the locations of exergy losses, as well as study power plants in terms of their quality [1,[41][42][43][44][45][46][47][48][49][50][51][52]. Exergy analysis remains a way of locating process or system inefficiencies which first law of analysis cannot do.…”

Investigation of the Performance of Heat Pump Waste Heat Regeneration Runner Dehumidification of Air Conditioning Systems

“…For residential buildings, air-source heat pumps have a wide range of applications because they can flexibly control the load, meet the needs of cooling, heating, and dehumidification, and meet the needs of individual differences in the human body [1][2][3][4][5]. However, there are still some problems in the application of air-source heat pumps, including low COP of cooling and heating conditions, large air supply temperature difference, and obvious blowing sensation, which affect the thermal comfort of the human body, and the inability to meet indoor requirements [2,[6][7][8][9][10], and the independent control requirements for temperature and humidity [11][12][13][14][15][16]. The study by [17] proposed an air conditioning system coupled with a dehumidification runner and a medium and high-temperature heat pump.…”
