The Energy Conservation Measure for Small Steam System by Using Technology of Screw Compressor

For many elderly people, residential energy conservation options are often limited to little or no cost measures such as reducing their winter nighttime thermostat setting. As a result, conflicts can arise between the need to preserve health and the necessity to conserve energy. Under these circumstances, accidental hypothermia is an important and growing concern. This study examines the association between concern for health and the adoption by elderly persons of a lowered winter nighttime thermostat setting. Evidence from two surveys of elderly respondents who maintain separate owner-occupied residences shows that health and thermal comfort concerns are the major reasons for nonadoption of this energy conservation measure. Methods are presented for increasing energy conservation while maintaining a healthful home environment.

Decision Support Process

Building energy conservation measure (ECM) of insulation materials suitable for the domestic situation in the construction sector (passive) is established. The ECMs of insulation materials were classified into walls, roofs, and floors. Also, economic evaluation databases, which are composed of material costs, labor costs, and expenses for constructed alternatives, were built. After setting the target building and deriving the ECM list of insulation materials for the target building, the energy use evaluation and economic evaluation were performed for each constructed alternative. Based on this, the optimal building energy conservation measure of the target building was derived by applying the decision-support process.

The objective of this study is to conduct a field survey, including data collection and measurements to study the potential of energy conservation measure of Rerm-Udom sugar factory in Udon Thani. The boiler efficiency is measured and calculated using the indirect method. The results of this study show that the most significant loss of the boilers is heat loss due to exhaust gas, which is 17.2%, while the rest heat loss is around 2%. The proposed energy conservation measure to improve the performance of the boiler is to install the economizer, which helps to increase the boiler efficiency for 1.5% and helps to produce additional electricity for 2,362,800 kWh per year or 7,088,400 Baht per year. The investment cost of the economizer is 7,200,000 Baht and the maintenance cost is around 1,000,000 Baht per year. Therefore, the payback period of the energy conservation measure is 1.2 years.
