Abstract (en)
[origin: WO2019023267A1] A refrigerant blend measurement system (RBMS) (77) is configured to determine a composition of a refrigerant blend within a refrigerant circuit (76) of a vapor compression system. The RBMS includes: a sample vessel (70) configured to receive a portion of the refrigerant blend, wherein the sample vessel comprises a first sensor configured to measure a temperature of a liquid portion (80B) of the refrigerant blend and a second sensor configured to measure a pressure (80A) of the refrigerant blend. The vapor compression system includes a control unit (84) configured to: receive a measured temperature value from the first sensor; receive a measured pressure value from the second sensor; determine a composition of the refrigerant blend based on the measured temperature value and the measured pressure value; and determine that the composition is beyond a predefined threshold stored in the memory, and in response, modify operation of the vapor compression system.
