Title: Innovations of Sooho Jang in Scroll Compressor Technology

Introduction

Sooho Jang is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of compressor technology, particularly with his innovative designs for scroll compressors. With a total of 6 patents to his name, Jang's work has enhanced the efficiency and performance of refrigeration systems.

Latest Patents

One of Jang's latest patents involves a scroll compressor that features a first back pressure unit. This unit allows refrigerant to flow from a first compression chamber to a back pressure chamber while preventing reverse flow. Additionally, a second back pressure unit facilitates the flow from the back pressure chamber to a second compression chamber, also blocking reverse flow. This design reduces pressure pulsation in the back pressure chamber and minimizes leakage between compression chambers. It also effectively reduces friction loss by adjusting the pressure in the back pressure chamber, which is particularly beneficial for enhancing compression efficiency under low load operating conditions.

Another notable patent by Jang describes a scroll compressor with a first sealing portion defined between the inner surface of an orbiting wrap and the outer surface of a non-orbiting wrap. A second sealing portion is defined between the inner surface of the non-orbiting wrap and the outer surface of the orbiting wrap. The sealing surfaces where the wraps contact each other are designed to enlarge the sealing area, which helps suppress or prevent leakage of refrigerant in the compression chamber. This innovation improves both indicated efficiency and volumetric efficiency.
