Finned-Tube Condenser Cleaner Machine
Finned-Tube Condenser Cleaner Machine

Now a day the mostly air condition are use the air for reducing the temperature at the condenser unit. Moreover many dusts are adhering in area of fin coil. From this reason the heart reduction efficiency is decreased and increasing the energy consumption. Thus the aim of this research is to design the finned-tube condenser unit cleaner machine for increasing the heart reduction efficiency. From the results of experiment it found that the finned-tube condenser cleaner machine is desirable when comparing with the performance before used. By the original performance the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 34179 Btu/hr 2.62 and 8.9 Btu/hr.Watt. On the other hand the refrigeration effect (C.O.P) and (EER) is 39766 Btu/hr 3.12 and 10.7 Btu/hr.Watt respectively when the condenser unit cleaner machine is used. Based on this condition the value of the refrigeration effect and (EER) are increase to 16.35% and 19.19% respectively. Thus the heart reduction in condensing unit can be aided the performance and prolong the life time of air condition by depending on the cleaning of condensing unit.

The design and development of young rice planting machine for use in the North Eastern part of Thailand
The design and development of young rice planting machine for use in the North Eastern part of Thailand

This research aims to investigate the efficiency and quality of young rice planting machine which is suitable for the North Eastern part of Thailand. The investigation applies the notions of planting young rice manually by farmers into the design of a battery-driven young rice planting machine. The researcher started with the study of transplanting methods of agriculturists in the North Eastern part and the design principles of young rice planting machine. Next the components were calculated and engineering design was drawn. Then the machine was tested in terms of its efficiency and quality. The data were analyzed in terms of means. The results show that the efficiency of the machine regarding planting performance is 90 % the appearance of the machine functions applications engineering and safety achieve the average point of 3.70 which is considered satisfactory.

This research objective is to improve the overall equipment effectiveness of the water filtration systems in the case study of the Water Treatment Plant which divides the water production into 4 production lines. The water filtration system has an electric actuator and gear is the main machine in the water filtration system. An electric actuator and gear have more machine breakdowns. That makes the water filtration system is the bottleneck of the water production process. This research study is divided into two steps: the first step is the presentation of the equation and the steps to measure the Overall Equipment Effectiveness of the water filtration system. The equation used data from the computer maintenance management system to analysis on mean time between failure data (MTBF) mean time to repair data (MTTR) and water production process data. The results can be improved the overall equipment effectiveness of the water filtration system increased to 0.11% 0.68% 0.44% and 2.44% respectively in each production process line. And increased Quantity of Filtration Water increased to 328500 m3/year 1168000 m3/year 1022000 m3/year and 3832500 m3/year respectively in each production process line. In this research used the pillar of focus improvement. By adding a protection system to prevent machine breakdown because of the most of the problems are found that the protection system malfunctions. This is the most problem in the 4th And then used engineering knowledge to improve water production and the success factor are required a human resources of all parties to cooperate brainstorm and analyze the causes of various losses in order to eliminate them.

การพัฒนาเครื่องอบแห้งข้าวเปลือกแบบไหลต่อเนื่องด้วยเทคนิคการแผ่รังสีความร้อนในแนวรัศมี

The objective of this research was to design and development of a continuous flow paddy dryer with infrared radial radiation technique. The prototype of dryer consists of two concentric circular cylinders cylinders which the paddy drying chamber is height of 1 m. The inner cylinder has diameter of 26.5 cm made from glasses and outer cylinder has diameter of 29.5 cm made from perforated (1.75 mm) steel sheet. At the center of cylinders installed 1200 w of electric infrared heater. A hopper was installed on the top of the chamber while 120 w of blower and paddy flow control were installed at bottom of chamber. The performance of the dryer in terms of specific energy consumption (SED) drying rate (DR) and quality of paddy i.e. head rice yield (HRY) and whiteness index (WI) were evaluated by drying 15 kg of paddy with initial moisture content of 23-26% (w.b.) by using the drying conditions of 80oC of drying chamber temperature 1.075 m3/min of air flow rate and 0.837 1.228 1.875 and 2.308 kg/min of paddy flow rate. The results found that paddy flow rate at 1.875 kg/min is the optimum condition because gave the highest DR lowest SEC and rice qualities (HRY and WI) closely to control.
