Estimating the term…
A dynamic receiver is included in parallel to an expander of a heating, ventilation, air conditioning, and refrigeration (HVACR) system. The dynamic receiver allows control of the refrigerant charge of the HVACR system to respond to different operating conditions. The dynamic receiver can be filled or emptied in response to the subcooling observed in the HVACR system compared to desired subcooling for various operating modes. The flow through an expander of the HVACR system can be controlled to account for the mass flow rate through an outlet valve of the dynamic receiver when the dynamic receiver is emptied, preventing or reducing instability or effects on system parameters such as the suction superheat.
A heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:
A method of controlling a heating, ventilation, air conditioning, and refrigeration (HVACR) system including a circuit including an expander, a dynamic receiver in parallel with the expander, and an outlet valve configured to control flow from the dynamic receiver to the circuit, the method comprising:
