Refrigeration system with rotary pressure exchanger
A recently granted patent (Publication Number: US11982481B2) discloses a refrigeration system that includes a rotary pressure exchanger with a rotor forming multiple channels. The system is designed to receive a first fluid from a gas cooler or condenser and a second fluid from an evaporator, exchanging pressure between them. The first fluid is output in a liquid state or a two-phase mixture, while the second fluid is output in a supercritical or subcritical state. The system further includes sensors for monitoring flow rates and pressures, ensuring efficient operation based on sensor data.
Additionally, the patent describes a system with a memory and processor connected to sensors for controlling the flow rates of the first and second fluids in the rotary pressure exchanger. The processor adjusts the flow rates based on sensor data to optimize the system's performance. The system also includes valves for flow rate control and can handle carbon dioxide as the first and second fluids. Furthermore, a method outlined in the patent involves receiving sensor data, controlling flow rates of the fluids, and exchanging pressure between them in the rotary pressure exchanger. The method includes utilizing temperature and pressure sensors, along with valves for flow rate adjustments, and can handle carbon dioxide as the working fluids for efficient refrigeration operations.
