Title: Innovations of Greg Derosier

Introduction

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

Latest Patents

Among his latest patents is the "Oil separator and return for ejector-based direct expansion (DX) evaporator." This innovative 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, which work together to optimize the refrigeration process. 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 of 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 as well as 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, stabilizing the superheat of the outlet vapor and reducing fluctuations in outlet superheat caused by excess unevaporated liquid flowing from the outlets of the tubes due to mal-distribution at the inlet.
