Mechanical analysis of key components and machine performance for the oil regeneration project compressor
Special scroll profiles among the functional general scroll profiles were chosen to make a study on the integrative performance of the scroll compressor. Based on such profiles, it was further researched for all factors working on the integrative performance of the scroll compressor and the analysis of gas power was made on the key components influencing the integrative performance and four basic parameters including height, spindle rotation, involute angle and radius parameter of base circle. It was analyzed that the relation of axial gas power, radial gas power tangential gas power, overturning torque and rotation torque of dynamic and static vortex plate by employing the Genetic Algorithms (GA) of MATLAB to obtain the restricted parameter range, and to conclude that there is a linear relationship among four basic parameters and the overall force. Instance calculation was conducted to prove the validity of the restricted range that compression ratio and volume utilization have been increased greatly after optimization, so as to avoid the blindness of parameter selection and consequently improve the integrative performance of the scroll compressor.
The Study and Outlook of Air-Conditioning Refrigeration Compressor Technology Development
This paper introduced the development process and status quo of compressor.Particularly recommended the recent domestic studies about the type of scroll compressor lines,refrigerant,lubrication,frequency-converse technology and so on.Pointed out the direction of scroll compressor development in the future by reviewing the history of scroll compressor.In recent years,with the development of compressor-related industry technology,refrigeration and air-conditioning compressor technology has been rapidly developed and energy efficiency of the whole refrigeration system has been greatly improved.However,due to the double pressure of short supply of energy and environmental protection in future,we have to constantly explore the new technologies of refrigeration and air conditioning industry to meet the requirements of energy development strategy that fits the situation of our country and to achieve the objective of building a harmonious society.
Physical Principles of Wind Energy Conversion
The primary component of a wind turbine is the energy converter which transforms the kinetic energy contained in the moving air, into mechanical energy. For the initial discussions of principles, the exact nature of the energy converter is irrelevant. The extraction of mechanical energy from a stream of moving air with the help of a diskshaped, rotating wind energy converter follows its own basic rules.
