The application of integrated energy use in the agriculture sector It is presented in the form of using renewable energy from solar energy to produce electricity to use in conjunction with other sources of electricity such as generators or electric power systems. Using solar panels or solar cells the size and number of panels does not exceed 300 watts 4 panels and the electrical system of the electrical system. Supply electric power to the water pump size does not exceed the rating of 1500 watts 220 volts. Solar power supply systems alone may be affected by weather conditions or electrical power supplies. Including the quality of electricity obtained from solar energy and will result in the water pump not working efficiently. Therefore the application of solar energy by using a power supply system from 2 sources by using a hybrid inverter device to select the power supply from the solar cell is the main power and the power supply from the memory system is the backup power. Therefore a research project on the application of solar water pumps in a mixed system for agriculture is proposed to increase the efficiency of electric power distribution. This application of solar water pump hybrid system for agriculture when used with water pumps can normally help to save electricity and can also use solar energy instead of using electricity to pump water. Let the water pump and can work efficiently.

Study on Energy – Reducing Jerusalem Artichoke Dessert The objective is to study the basic recipe of Jerusalem Artichoke dessert. And to study the level of sugar consumption in the 5 formulas of Jerusalem Artichoke 0% 25% 50% 75% and 100% By planning a randomized complete block design (RCBD) experiment the sensory quality in terms of appearance color smell taste texture and overall preferences was assessed by a (9 - point preference-scoring tasting method. Hedonic Scale) by a taster of 40 and 80 Who is a student in Food and Nutrition Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon And bringthe information obtained To find the mean (x ̅) analyze the variance (Analysis of Variance ANOVA) and compare the mean difference by means of Least significant Difference (LSD) and Duncans New Multiple Range Test (DMRT). The results were analyzed by a statistical package. From studying the basic recipe of Jerusalem Artichoke Dessert The tasters accepted the basic recipe of Jerusalem Artichoke Dessert the second formula in terms of appearance color smell taste texture and overall preferences. The average score was 8.07 8.08 7.85 7.93 7.98 and 7.98 which were in the medium to high preference level. When it was analyzed the variance and compared the statistical differences. It was found that the appearance color taste and texture The difference was statistically significant at 0.05 level. And overall preferences There was no significant difference at the 0.05 level. From the study of reducing sugar content in Jerusalem Artichoke Dessert Energy - reducing Taster accepted the recipe 75% for appearance color flavor texture and overall preference. With an average score of 8.05 7.93 7.55 7.82 and 7.83 In the level of moderate to very favorable As for the smell The tasters accepted the recipe 50% with an average score of 7.52 being moderate. When the variance was analyzed and statistical differences were compared. It was found that the appearance color smell taste texture and overall preference. There was a statistically significant difference at the 0.05 level.

The objective of this research is to study the techniques of profit quality analysis and the consistency of the profit quality with different profit quality analysis techniques; and to compare profit sustainability between large companies and small companies of the industrial energy and utilities group and the petrochemical and chemical group. The data is collected from financial statements and data entry forms (Form 56-1) from 2012 to 2018. A total of 47 companies are analyzed using descriptive statistics including mean and standard deviation; and inferential statistics including multiple regression analysis and analysis of the average difference between 2 groups The research found that in the analysis of the profit quality consistency in all 4 methods there were only 13 companies in the energy and utilities group with consistent quality of profits accounting for 39.39%; and 20 with inconsistent results accounting for 60.61%. In the petrochemical and chemical group there was only 1 company with consistent quality in all 4 methods representing 7.14%; and 13 companies with inconsistent quality representing 92.86%. In addition when comparing the profit sustainability between large companies and small companies it was found that there was no statistical difference in profit sustainability (sig = 0.305> 0.05). When comparing the profit sustainability between energy and utilities group and the petrochemical and chemical group it was found that petrochemical and chemical companies had a higher profit sustainability than the energy and utilities group at statistical significance of 0.01 (sig = 0.009 <0.01).

Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This thesis presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.

This study investigates three different types of power plant include a trilateral cycle (TLC) subcritical organic Rankine cycle (ORC) and supercritical ORC power plant driven by geothermal heat source with mass flow rate 1 kg/s and temperature of 100๐C 110๐C and 120๐C. with 27 substances were examined as the working fluid of the power plant. While the net power output of 4.78 kW and 7.74 kW is obtained from the subcritical ORC with RC318 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 11.85 kW is obtained from the subcritical ORC with R227ea as its working fluid when the heat source temperature is at 120๐C. The net power output of 5.64 kW and 9.16 kW are obtained from the supercritical ORC with R218 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 12.88 kW is obtained from the supercritical ORC with R143a as its working fluid when the heat source temperature is at 120๐C. Furthermore the net power output of 7.96 kW 12.27 kW and 17.38 kW are obtained from the TLC plant with heptane as its working fluid when the heat source temperature are at 100๐C 110๐C and 120๐C respectively.
