Abstract:
1. A refrigeration circuit having a system charge and a system charge storage area, said system charge area comprising: a condenser having a set of micro-channel heat exchanger coils, said condenser appropriately sized to receive a first volume of the system charge; a compressor for compressing the system charge from an expanded state to a compressed state; a sealed refrigerant charge holding area fluidly connected to said condenser and said compressor, said sealed refrigerant charge holding area appropriately sized for storing a second volume of the system charge during a system pumpdown; and a receiver fluidly connected to said sealed refrigerant charge holding area, said receiver appropriately sized to receive a third volume of the system charge during a system pumpdown; wherein the sealed refrigerant charge holding area is positioned on a downward slope from the condenser to the receiver.
