Claim 7:
8. A method of controlling a heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:
determining, using a controller, a target quantity of working fluid to be stored in a dynamic receiver included in the HVACR system, the target quantity based on a subcooling threshold value and a measured subcooling value;
comparing a quantity of working fluid in the dynamic receiver to the target quantity;
when the quantity of working fluid in the dynamic receiver exceeds the target quantity;
removing working fluid from the dynamic receiver by opening an outlet valve directly downstream of the dynamic receiver, and
when the quantity of working fluid in the dynamic receiver is less than the target quantity, adding working fluid to the dynamic receiver by opening an inlet valve downstream of a first heat exchanger and upstream of a second heat exchanger with respect to the working fluid flow path in the HVACR system,
wherein the dynamic receiver is in parallel with an expander included in the HVACR system, the inlet valve is located downstream of a first heat exchanger of the HVACR system and upstream of a second heat exchanger of the HVACR system, and the outlet valve is located downstream of the first heat exchanger of the HVACR system and upstream of the second heat exchanger of the HVACR system.
