Title: Innovations by Shri Gopalan in Refrigeration Technology

Introduction

Shri Gopalan is an accomplished inventor based in Westminster, MD (US). He has made significant contributions to the field of refrigeration technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and capacity of direct expansion refrigeration systems.

Latest Patents

One of Shri Gopalan's latest patents is the "Oil separator and return for ejector-based direct expansion (DX) evaporator." This system and method aim to increase the refrigeration capacity of a direct expansion refrigeration system. The design includes a vapor separator and a vapor ejector. After the throttling process at the expansion device, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. The vapor goes to the ejector, along with refrigerant vapor from the outlet of the evaporator. The ejector sends oil and vapor and liquid refrigerant to an oil separator, which returns oil to the compressor and sends the liquid and vapor refrigerant to the evaporator.

Another notable patent is the "Direct expansion evaporator with vapor ejector capacity boost." This system also aims to increase the refrigeration capacity of a direct expansion refrigeration system. Similar to the previous patent, it features a vapor separator and a vapor ejector. After the throttling process, the mixture of liquid and vapor enters the inlet separator. The vapor separator generates vapor to power the ejector through flashing warm refrigerant liquid from a higher temperature and pressure to a lower pressure. The cooler refrigerant liquid then goes to the evaporator coil inlet. This system stabilizes the superheat of the outlet vapor and reduces fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to mal-distribution at the inlet.
