Patent ID: 11137171

Abstract:
A transcritical R-744 refrigeration system comprising at least one first compressor for compressing an R-744 refrigerant, a gas cooler for cooling the R-744 refrigerant compressed by the at least one first compressor, a throttling device for decreasing the pressure of the cooled R-744 refrigerant, a receiver for separating the R-744 refrigerant, a first heat exchanger for exchanging heat between the cooled R-744 refrigerant and the R-744 vapors separated by the receiver before the R-744 vapors are transported to the at least one first compressor, and an integrated R-744 refrigerant-based air-conditioning assembly comprising a second plurality of compressors and an air conditioner comprising a second heat exchanger and an evaporator, wherein the system is operatable in a dehumidification mode wherein the R-744 vapors exiting the gas cooler are fed through the second heat exchanger to heat and dehumidify the passing ambient air before being fed to the receiver.
