A study on the starting characteristics of a reciprocating compressor for a household refrigerator

摘要

The starting characteristics of a reciprocating compressor used in household refrigerators are discussed in this paper. Failure of starting the compressor, which usually occurs at low line voltage, causes the reduction of compressor lifetime. Therefore the starting characteristics in the compressor design must be carefully considered, especially where the line voltage is unstable. Experimental investigations on the compressor starting voltage have been performed on the effect of design parameters such as discharge a valve, valve port area, piston pre-caulking torque with the compressor which has ball joint type connecting rod. Also numerical analysis has been carried out simultaneously in order to develope a computer simulation program.
