MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202527127038 A) filed by Evapco, Inc. on December 15, 2025, for Direct Expansion Evaporator With Vapor Ejector Capacity Boost.
Inventors include Derosier, Greg; and Gopalan, Shri.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: A system and method for increasing the refrigeration capacity of a direct expansion refrigeration system having 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 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. Furthermore, the 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 maldistribution at the inlet.
