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.
