    Abstract: A heat-pump system may include an outdoor heat exchanger, an expansion device, an indoor heat exchanger, a compressor, and a multiway valve. The expansion device is in fluid communication with the outdoor heat exchanger. The indoor heat exchanger is in fluid communication with the expansion device. The compressor circulates working fluid through the indoor and outdoor heat exchangers. The multiway valve may be movable between a first position corresponding to a cooling mode of the heat-pump system and a second position corresponding to a heating mode of the heat-pump system. The working fluid flows in the same direction through the outdoor heat exchanger in the cooling mode and in the heating mode, and the working fluid flows in the same direction through the indoor heat exchanger in the cooling mode and in the heating mode.

    Abstract: A refrigerant control system includes: a reversing valve including: a first inlet configured to receive refrigerant output from a condenser; a first outlet configured to output refrigerant to an inlet of an evaporator located inside of a building; a second inlet configured to receive refrigerant output from the evaporator; and a second outlet configured to output refrigerant to an inlet of a compressor that pumps refrigerant to the condenser; a reversing module configured to: selectively actuate the reversing valve to a first position such that: refrigerant flows directly from the second inlet to the second outlet; and refrigerant flows directly from the first inlet to the first outlet; and selectively actuate the reversing valve to a second position such that: refrigerant flows directly from the second inlet to the first outlet; and refrigerant flows directly from the first inlet to the second outlet.

    Abstract: A system for charging an outdoor unit with refrigerant includes a sensor configured to measure a refrigerant concentration and a user device configured to receive the measured refrigerant concentration. The system includes that the user device is configured to, in response to the measured refrigerant concentration exceeding a threshold, generate and display an alert on a user interface of the user device indicating the measured refrigerant concentration exceeds the threshold.
