Classification: CPC F | IPC F

Claim 0:
1. A heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising a fluid circuit including:
a compressor;
a first heat exchanger;
an expander;
a second heat exchanger;
a dynamic receiver, the dynamic receiver in parallel with the expander with respect to the fluid circuit;
an inlet valve positioned directly upstream of the dynamic receiver, the inlet valve downstream of the first heat exchanger and upstream of the second heat exchanger with respect to the fluid circuit; and
an outlet valve positioned directly downstream of the dynamic receiver, the outlet valve downstream of the first heat exchanger and upstream of the second heat exchanger with respect to the fluid circuit; and
a controller configured to control the inlet valve and the outlet valve,
wherein the controller is configured to determine a target quantity of working fluid to be stored in the dynamic receiver based on a measured liquid line subcooling value and a subcooling threshold value, and
when a quantity of working fluid stored in the dynamic receiver exceeds the target quantity, the controller is configured to reduce the quantity of working fluid stored in the dynamic receiver by opening the outlet valve until the target quantity of working fluid is stored in the dynamic receiver.
