Reheat operation for heat pump system

A tangible, non-transitory, computer-readable medium comprising instructions, wherein the instructions, when executed by processing circuitry, are configured to cause the processing circuitry to:

• position a reversing valve of a heat pump system in a first configuration to direct refrigerant from a compressor of the heat pump system toward a modulating valve of the heat pump system in a modulating reheat mode of the heat pump system;
• adjust a position of the modulating valve to an intermediate position of a plurality of intermediate positions in the modulating reheat mode, wherein the plurality of intermediate positions is between a first position of the modulating valve and a second position of the modulating valve, and wherein, in each intermediate position of the plurality of intermediate positions, the modulating valve is configured to direct a first portion of the refrigerant through an outdoor heat exchanger of the heat pump system and to direct a second portion of the refrigerant through a reheat heat exchanger of the heat pump system in parallel with one another;
• and
• position the reversing valve in a second configuration to direct the refrigerant from the compressor toward an indoor heat exchanger of the heat pump system in a heating mode of the heat pump system.

A heat pump system, comprising:

• a refrigerant circuit comprising a compressor, an indoor heat exchanger, an outdoor heat exchanger, a reheat heat exchanger, a modulating valve, and a reversing valve,
• wherein the reversing valve is configured to receive refrigerant from the compressor and adjust between a first configuration to direct the refrigerant from the compressor toward the modulating valve and a second configuration to direct the refrigerant from the compressor toward the indoor heat exchanger,
• wherein the modulating valve is configured to apportion the refrigerant received from the reversing valve between the outdoor heat exchanger and the reheat heat exchanger, and
• wherein the refrigerant circuit is configured to direct a first portion of the refrigerant from the modulating valve to the outdoor heat exchanger and to direct a second portion of the refrigerant from the modulating valve to the reheat heat exchanger in parallel with one another.
