Details: Mahasarakham University designs and installs LED lamps for lighting in every building and to control the automatic activation. Today’s energy-saving technology It produces a true white light LED bulb. The light from an LED bulb produces a brighter light than conventional incandescent bulbs. Is white light that helps conserve the eyes Its service life is longer than conventional lamps. 50,000 hours on average Vibration saving energy costs LED bulbs consume less energy than incandescent bulbs. Fluorescent lamp In which if compared with incandescent bulbs At the same size, LED bulbs save up to 85% more energy, resulting in lower electricity bills. LED bulbs do not require mercury vapor. And putty with phosphor like fluorescent or chopsticks without heavy metals Therefore it is not a problem with the environment, no UV rays, so it has no negative effects on the skin and eyes.
Within Maha Wittaya Lan Mahasarakham, selection, installation and modification of air conditioners that can save high energy Is labeled with energy saving 5 certified by the department of Electricity Generating Authority (EGAT) Airbestbuy show details of Fiber-saving label 5 in the description of the product and the air conditioner with inverter system. Compressor speed can be adjusted. To suit the cold at that time when the temperature in the air-conditioned room has reached the set value. Air conditioning can reduce the speed.
In the running of the compressor down And maintain a constant temperature inside the room Thus saving energy 40-60% than general air conditioners

Renewable Energy Sources in Campus

Description:

Mahasarakham University Have a policy to procure renewable energy To be used in various activities of the university Which has been installed Solar cells on the roof of 6 university buildings with a capacity of approximately 2880000 kWh per year.
The solar power generation system installed on the roof has been conceptualized. Will install a total of 12 buildings, including the roof of the Faculty of Education, the roof of the Academic Service Building, the roof of the Faculty of Education, the roof of the Faculty of Medicine building, the roof of the Faculty of Accountancy and Management 1 building, the roof of the school building of the Faculty of Accounting and Management. 2, the roof of the first-ever dormitory building, roof of the Rajapruek Dormitory Building, the roof of the Faculty of Technology Building, the roof of the Building of the Health and Physical Fitness Center, the roof of the Faculty of Technology Building And roof of the food processing building The power generation system consists of a set of crystalline solar panels. (Crystalline) because this type of solar panel is a new technology. And a high efficiency of electricity (more than 18%) makes it suitable to be installed on the roof. The installed capacity of approximately 1 MWp (DC) uses 2,857 solar panels, which are the source devices used to generate electricity from the sun. And the electricity produced by solar panels will be direct current. And will be forwarded to the Inverter, which is a device used to convert DC power To AC power And transmitted to the transformers to convert the voltage to be suitable for the electricity supply to the existing electrical system of the university
Where between the inverter and the existing electrical system of the university, there will be an electrical control system Which is a protective device that meets the standards of the regional electric power Total electricity generated from the power generation system It will be used in all universities and there will be a system to prevent electric energy from flowing back to the regional electricity system.

A Study of Models of Life Quality Development of Isan Marginal Communities as Affected by Installation of the Solar Home System.

The electricity production system by using solar home cells is regarded as a substitute for energy which the state provides for the marginal communities because the area cannot be extended for putting up pylons with electric cables, all this for the marginal communities to have better life and being. The purposes of this thesis were to examine the history and development of the electricity production system by using solar home cells, and to examine models of life quality of Isan marginal communities as affected by the use of solar home system by using solar home cells. Approach: The sample consisted of 100 people in Isan marginal communities who lived in mountains, on highlands, on lowlands, and in national park areas with totally 4 areas. The instruments used for collecting data were an observation form, an interview form a group discourse note-taking form and workshop note-taking form. The 6 aspects of Minimum Needs (MN) was included into every instrument. The data analysis results were subsequently presented by means of a descriptive analysis: Results: 1for the history and development of the solar home system, it was found that Thailand began using solar cells in 1977 by the Unit of Volunteer Doctors. At present, solar cells are used in various types: battery charging stations, communication systems, water pumping system, traffic light signals, blinkers and electric systems in marginal communities in general.2) for the models of life quality development of Isan marginal communities as affected by the use of the solar home system, the life quality was developed according to indicators of maximum needs in these 6 aspects: the model of developing good health, the model of developing progressive incomes, the models of This value cultivation and the model of developing cooperative development. It was found that the positive effects were at 98.67% and negative effects were at only 1.33%. Conclusion/Recommendation: There for, it can be seen that the solar home system can generate more positive outcomes than negative ones in life quality development of Isan marginal communities. This is in accordance with all the 6 aspects of Maximum Needs (MN).
