Title: Air conditioning scroll compressor starting characteristics optimized rotor noise and vibration control ofAuthor: Qi JilongDegree-granting units: Jilin UniversityKeywords: rolling piston compressor;; permanent magnet synchronous motor;; sensorless control;; noiseSummary:In this paper, and Qingdao fast to the company's cooperation project "air conditioning compressor controller software development" topics, the main research air-conditioning
With a rolling piston compressor Magnetic lifter drive and performance optimization issues. Through this study to optimize the compressor starting process, proposed
Compressor vibration and noise to improve the performance of the program. This work is divided into the following sections.1, through the rolling piston compressor
Structural characteristics and working principle of the analysis, simulation of the rolling piston compressor in the work of the suction chamber and compression chamber pressure changes in order to
And pressure changes and vane rotor and other parts of the force acting on the rolling machine with rotor angle changes. Established a rolling piston compressor work
Load torque for the resistance model.2, the compressor through the simulation http://www.999magnet.com/products/131-magnetic-lifter model tested the open-loop start-up programs, and by increasing the
Constant torque load and the load resistance of the compressor to debug and improve the starting performance of the compressor. Verified through simulation proposed start-up programs
Rationality and the parameters involved in the testing method.3, in order to improve the rolling piston compressor starting performance, this paper adopts DSP
Chip presents a relatively simple way to start and build a test system. Through theoretical analysis and experimental optimization of a repeated start over
Process accelerated curve, starting the compressor to shorten the process time, enhanced reliability, even under pressure in a smaller smooth start
.4, in order to improve the rolling piston compressor noise and vibration performance, proposed to improve the compressor's drive from the effect of the compressor
Vibration and noise performance improvement program. Confirmed by simulation using the torque side of the control system, speed control to the side
Sampling time and change programs to reduce the speed of the compressor-driven process fluctuations. This article also through the use of different drive systems in the consumer
Interior of the compressor-driven sound vibration and noise performance is tested. The results show that different vibration on the compressor drive system
And noise performance have a significant impact.Degree Year: 2009
