  • Publication number: 20260160435
    Abstract: A dehumidification system including a heat exchanger that has a coolant coil with a coolant coil section and a reheat coil with a reheat coil section. The coolant coil section and the reheat coil section are intertwined with each other within an envelope of the heat exchanger. The dehumidification system also includes a coolant circuit that has a condenser fluidly connected to the coolant coil, and a reheat circuit that has a heater operably coupled to the reheat coil. The coolant circuit may circulate a refrigerant to cool an airflow flowing through the heat exchanger, and the reheat circuit may circulate a reheat fluid to heat the airflow. The intertwined nature of the coolant coil section and the reheat coil section is configured to dehumidify the airflow within the heat exchanger envelope.

  • Patent number: 12298031
    Abstract: A Variable Refrigerant Flow (VRF) dehumidification system. The system has at least one condenser module in fluid communication with one or more indoor air handlers. At least one evaporator coil is in fluid communication with the indoor air handlers and at least one reheat/reclaim coil. The evaporator and reheat/reclaim coils are also in communication with the condenser module. A plurality of electronic expansion valves (EEVs) are in fluid communication with the indoor air handlers. A plurality of sensors is disposed in the system and are in communication with at least one VRF dehumidification system controller. In one embodiment, a logic is stored in a non-transitory computer readable medium that, when executed by one or more processors, causes the VRF dehumidification system to monitor the data input from the plurality of sensors and regulates the capacity of the VRF dehumidification system needed to maintain a set dew point parameter.
