The Control of the Refrigerants Distribution by Means of the Electric Expansion Valve

Abstract

In this paper, the control methods of the refrigerants distribution by means of the electric expansion valve are discussed.
The first, various electric expansion valves are introduced. And, the super heat degree of the compressor inlet refrigerants is the control target in the recent time. The above mentioned superheat control algorithms are discussed.
The second the modern advanced technology in the control targets and the sencing system and in the dynamic characteristics are developed.
The last, I discuss the control ideas for the purpose of the harmonic control of the many electric expansion valves.
