Global Solar Radiation Model
Opis:
Building solar plants with suitable placement in the correct geographic areas by utilizing information of solar radiation is the starting point of an investment projects of a solar energy facility. In these premises, several solar radiation models have been improved in order to estimate the solar radiation at a given location, all around the world. Complete and accurate solar radiation data at a specific region are quite important for the solar energy related researches. A number of formulas and models have been developed to estimate solar radiation for the locations, where measured values are not available. Thus, several empirical correlations have been developed in the literature. In this study, models such as the Angström equation, which is reviewed in literature, are used to estimate global solar radiation from sunshine duration in Turkey. In addition, the solar radiation models were examined at the identified solar radiation regions. This study investigates either the correctness of the model itself or the correctness of the estimation of global solar radiation, based on a set of statistical parameters such as R², RMSE, MBE, MABE, MPE and MAPE.

Opis:
In October 2014 in a building of Rzeszow University of Technology, a series of measurements was taken to calculate the parameters of a solar system with a flat collector, as installed on the roof of the building. The following parameters were obtained: the value of solar radiation intensity, the temperature of external air, the temperature on the collector, the temperature of water in the tank and the temperature of glycol on the supply and return lines. On the basis of the data received, charts were made to visually present how changes of solar radiation intensity affected parameters of the system. The study was conducted in autumn when the intensity of solar radiation decreases, compared with summer months. The publication aims to show that the solar system brings energy gains in periods of transition, and the instantaneous intensity of solar radiation are comparable to those in the summer.

The article discusses the impact of the size of the shading caused by natural obstacles as the depth of the frame on the heat balance of the room, thus the selection and size of air conditioning equipment. Taking into account this phenomenon on the design stage, we are able to avoid wrong device selection, and thus reduce cost of whole installation. A thorough analysis of the affection of shading in passive construction through the use of shading elements, is an opportunity to reduce the flow of solar energy in the summer and thereby improve the energy consumption of the building.

The objective of the study was to establish the configuration of the system model to allow the effective recovery of gray water by solar photocatalysis with TiO2 nanoparticles for irrigation of crops. A programmable solar photoreactor based on an S7 1500 PLC and online measurement sensors were used as materials. The inductive method was used to analyze the samples and the deductive method to determine the water quality. The research design used was experimental based on the response surface methodology (MSR) with 20 experiments, 6 of which were central experiments and 6 were axial experiments; these experiments were carried out on sunny days. As a result of the research, a gray water recovery model was obtained, part of this being an electronic system with a programmable photocatalyst, which allowed the development of the experiments. It was concluded that with a solar UV index of 12.21, a dose of titanium dioxide (TiO2) nanoparticles 1.973 g/L and with an exposure period of 60.041 minutes of the solar photocatalyst to UV radiation on sunny days, gray water was recovered in 90% with a confidence level of 95% and a significance α = 0.05, which translates into excellent quality according to the water quality index established in Peru (ICA-PE).

Opis:
This study is based on a 50-year data series (1964-2013) of total solar radiation (G) from the Kołobrzeg – station that is located on the Polish Baltic Sea coast and is characterised by a very high level of air quality. To find and remove gross errors, quality control checking procedures were applied in this study. Additionally, the homogeneity of the G series in this study has been tested on a monthly basis by using of the Standard Normal Homogeneity Test for single shifts. We found a statistically non-significant decrease in G during the period from 1964 to 2013. The decrease in the 5-year mean total solar radiation is evident from the beginning of the 1980s, with the minimum mean value occurring in the second half of the 1990s, while G slightly increased from the early 2000s. The analysis of seasonal G patterns shows that total solar radiation in summer is the most similar to the annual pattern and only the summer series trend shows a statistically significant decrease in G. We have also found two noticeable tendencies in monthly anomalies of G over the studied decades; they are negative trends in May and August. The shape of the decadal daily G histogram remained unchanged during the analysed decades.

Opis:
The data were recorded at the laboratory on the outflow Fugleberget (5 m a.s.1.) nearby the Polish Polar Station, Hornsund, south Spitsbergen. The second author recorded the data with instrument's during the 1989-1994 period. Temperature measurements on the ground surface, ground temperature at a depth of 5, 10, 20, 50, 75, 100, 150, and 200 cm, and radiation measurements were conducted in the laboratory on the outflow Fugleberget. The 5 years data were gathered, decoded and analysed using an LRI tape, LDA logger (Geopan), Seedata, Excel programs by the first author. A full year of data was collected only during years ł989 (after 12 July), 1991, 1992, 1993, as other years had data gaps. The maximum value of global radiation (K↓) reached 790 W/m2 in June 1991, 750 W/m2 in May 1992, and 690 W/m2 in July 1993. The largest amount of solar radiation received in May (420-500 MJ/m2), June (470-600 MJ/m2) and July (500-650 MJ/m2). The total amount of solar radiation in 1992 reached 2066 MJ/m2, and in 1991 and 1993 reached similarly 2349 MJ/m2 and 2397 MJ/m2 . Short-wave ref1ected radiation (KI) depends on global radiation and the ref1ectivity of the surface. At the present site the albedo reaches 70-80% in spring, and albedo of tundra was 10-20% during summer, as measured by Głowicki (l985a) in the summer 1980 and Niedźwiedź (1993) during the expedition of 1989/1990 .

Opis:
The aim of this study is to determine the effects of insect net placed on ventilation openings in greenhouses on temperature, humidity and radiation energy from indoor conditions. In addition, the effects of insect net on the agents used in biological control have been tried to be determined. The study was carried out between November 2017 and May 2018 in Kumluca district of Antalya in 2 glass and 2 plastic greenhouses. Greenhouses; the glass greenhouse without insect net (GCG), the glass greenhouse with insect net (GNG), the plastic greenhouse without insect net (PCG), the plastic greenhouse with insect net (PNG) is named as. Temperature, humidity and solar radiation values were measured in greenhouses. According to the results of the research; It was determined that the recommended temperature values for pepper development are only suitable in January and well below the recommended values in February. In other production months, the average temperature values of with insect net greenhouses (PNG-GNG) used in ventilation openings were found to be higher than without insect net greenhouses (PCG-GCG). When the results of relative humidity values were examined, it was observed that the use of insect tulle in the greenhouses was lower than the control greenhouses. It was determined that the solar radiation values were lower than the control greenhouses (PCG-GCG) of the insect tulle greenhouses (PNGGNG) in other months except January and May. Therefore, we can say that the use of insect net reduces the amount of solar radiation. Accord ing to the results of temperature values; the growth of Orius Leavigatus and Amblyseius swirski, one of the biological agents and resistant to high temperatures, was observed to slow down in all other months except February. For Phytoseiulus persimilis (30°C and above), we can say that this is a suitable environment and that the eggs have emerged in a shorter time. The most suitable average temperature for the development of Aphidius colemani was reached only in January. In other months, the development of this agent slows down, parasitic insecticides can be said to decrease the rate of parasitoids. As a result; It was determined that the temperature values were higher in the greenhouses where insect net was used and the solar radiation values were lower than the control greenhouses. However, since the use of insect net causes the temperature in the greenhouse to increase, it may create a positive development for some bio agents. It is thought that producers using insect net should make production considering these negativities in temperature and solar radiation.

Opis:
Multiple regression models were developed for calculating the regression coefficients a and b of the Angström-type equation for estimating the monthly average daily global radiation on a horizontal surface for six major climates in Jordan. The equations for a and b were developed from the available values of these constants reported in the literature for locations across the country, along with the sunshine duration and the values of ground albedo (ρ_g). The developed correlations were tested for their applicability by estimating the regression constants and the solar radiation for six locations spread over the country, which were Irbid, Amman, Azraq, Al-Shawbak, Ma’an and Aqaba. The remarkable agreement between the estimated and experimental data of solar radiation in those locations suggests a wide applicability of the method for the locations with sunshine duration ranging from 0.7 to 0.8. The maximum and minimum percentages of error for those locations were found to be 6.3, 0.05%, respectively.

The article presents an analysis of the impact of solar radiation on the temperature changes in the external three-layer partition of a smart building. Data for analysis were taken from temperature sensors located in individual layers of the wall and from a weather station on the roof of a building. The data were recorded 24 h in 5- and 15-minute intervals. The analysis period was one month in a winter season. The purpose of the analysis was to determine the correlation between the solar radiation measured as the illuminance and the temperature inside the wall. In the analysed period of one month the correlation was very weak. Also, considering only the illuminance over 10,000 lx, the correlation was noticeable, but still very weak. The use of innovative fiber optic technology with fibre Bragg grating was proposed to avoid incorrect measurements.
