Condition Systems

The air conditioner system plays a very essential role in our everyday lives. But air condition systems consume a lot of power. In this project, fan and AC are clubbed together and will work at different interval of time. This project is based on time variant i.e. if we set the delay time of say(1 hour) the AC will operate for 1 hour while the Fan is OFF and after 1 hour the AC will turn OFF and the Fan will operate and this operation will keep on repeating till the supply is turn OFF. The delay time for the operation of AC and Fan can be set according to our requirement through the program given to the arduino Different case studies was discussed for different Air conditioner companies for different capacities and their energy saving was analyzed for different cases.

Lean Tools

Energy cost is significant in many of the manufacturing activities. The efficiency of energy use is quiet low as there are substantial visible and hidden losses. Visible losses can be easily identified and corrective action can be taken. However hidden and indirect losses form a sizeable portion of the losses. Identifying these losses is not easy and requires an integrated approach which includes thorough study of process, operations and their interactions with energy use. Industries across sectors have implemented lean management principles which target various wastes occurring in the plant. This paper discusses case studies which highlight the exploitation of lean tools as a means for unearthing hidden energy saving potential that often go unnoticed. In addition to the energy savings which results in improved profits and competitiveness, the approach also aids the industry to pursue a path of sustainable manufacturing.

Testing Work

With the deepening of the energy conservation of the building, energy saving from the original design of building energy-saving gradually turned to the field detection and completion acceptance, which requires a corresponding energy-efficient means of detection. With the development of infrared technology, the combination of infrared technology and detection methods of building energy-saving, to further promote the development of building energy efficiency testing work. Compared to the traditional heat flow meter or hot-box method, infrared thermal imaging method has no effect on the measured object, detecting the surface temperature of quick reaction speed, accompanying with wide temperature range and high precision, is widely used in various fields of testing work, which has been particularly prominent in the thermal defect detection. In this paper, the method of infrared thermography is used to confirm whether the thermal defects exist in energy-saving construction or not. Testing results show that infrared thermography can accurately reflect the temperature distribution of building wall surface. Infrared thermal imaging to detect the building surface's energy efficiency, which is providing efficient and accurate means of detection for the evaluation of the building energy efficiency. This is to help carry out a comprehensive building energy-saving testing.
