Abstract: A modulating refrigeration system includes an evaporation unit and a condensing unit. The evaporation unit generates a first output airflow comprising a lower temperature, a lower relative humidity, or both than a first supply airflow and directs the first output airflow into a building. The condensing unit generates a second output airflow at a higher temperature than a second supply airflow and discharges the second output airflow to an unconditioned space. The evaporation unit comprises a first valve operable to direct a portion of refrigerant to a secondary evaporator and primary evaporator or to direct the entire flow of refrigerant to the primary evaporator and bypassing the secondary evaporator.

Abstract: An energy recovery ventilation unit includes an energy recovery ventilation core, a dehumidification system comprising an evaporation unit and a condensing unit, a first set of dampers, and a second set of dampers. In a first mode of operation, the first set of dampers is in a first position configured to inhibit the flow of a first airflow from a first panel inlet, and the second set of dampers is in a first position configured to inhibit the flow of a second airflow from a second panel inlet. In a second mode of operation, at least one of the first set of dampers and the second set of dampers is actuated to a second position wherein at least one of the first airflow and the second airflow flows to any one of the energy recovery ventilation core, the evaporation unit, and the condensing unit.

Abstract: An energy recovery ventilation unit includes an energy recovery ventilation core and a dehumidification system comprising an evaporation unit and a condensing unit. The energy recovery ventilation core receives a first and second airflow and discharges the first and second airflow after the first and second airflow experience heat and mass transfer. The evaporation unit generates a first output airflow comprising a lower relative humidity than the first airflow and directs the first output airflow into a building. The condensing unit generates a second output airflow at a higher temperature than the second airflow and discharges the second output airflow to an unconditioned space.

Abstract: A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, a modulating valve, and a liquid-cooled alternate condenser. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a third airflow to the primary condenser. The primary condenser receives the third airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the modulating valve. The modulating valve directs the flow of refrigerant to the primary condenser and to the alternate condenser. The alternate condenser receives a portion of the flow of refrigerant and transfers heat from the refrigerant to a flow of fluid.

Abstract: A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, and a water pump. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser. The primary condenser receives the flow of refrigerant and outputs the flow of refrigerant at a lower temperature through heat transfer with a flow of fluid. The flow of fluid is directed, by the water pump, to a heat exchanger or an external source, where heat is rejected from the flow of fluid.
