Patent number: 11959683Abstract: 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.Type: GrantFiled: January 26, 2022Date of Patent: April 16, 2024Assignee: THERMA-STOR LLCInventors: Grant M. Lorang, Gustavo Daniel Olivera, Weizhong Yu, David Treleven, Todd R. DeMonte, Robert John Motiff, Timothy S. O'Brien

Publication number: 20230258344Abstract: A dehumidification system includes a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, a superheat control evaporator, and a modulating valve. The superheat control evaporator is disposed parallel to the secondary evaporator and is configured to receive one of the inlet airflows and output a first airflow to the primary evaporator. The secondary evaporator is configured to receive another one of the inlet airflows and output a second airflow to the primary evaporator. The primary evaporator receives the first and second airflows and outputs a third airflow to the secondary condenser. The secondary condenser receives the third airflow and outputs a fourth airflow to the primary condenser. The primary condenser outputs a dischargeable airflow. The modulating valve directs the flow of refrigerant to the secondary condenser or to the primary evaporator, depending on the mode of operation.Type: ApplicationFiled: April 24, 2023Publication date: August 17, 2023Inventors: Scott E. Sloan, Weizhong Yu, Steven S. Dingle, Todd R. DeMonte, Grant M. Lorang, Timothy S. O'Brien

Patent number: 11639800Abstract: A dehumidification system includes an evaporator, a condenser positioned next to the evaporator, and a drain pan including a mist eliminator. The drain pan is disposed at least partially below the evaporator and the condenser. The drain pan at least includes a basin disposed at least partially below the evaporator. The basin includes a sloped bottom, a first rib disposed on the sloped bottom, a second rib parallel to the first rib and including a central gap, a third rib positioned between the first rib and the second rib, and an angled rib attached to the second rib. The third rib is parallel to and shorter than the first rib. The third rib is configured to at least partially block the central gap of the second rib. The angled rib is inclined towards the third rib and configured to change a velocity vector of the air flowing through the drain pan. The mist eliminator is configured to remove water droplets from the air.Type: GrantFiled: July 3, 2020Date of Patent: May 2, 2023Assignee: THERMA-STOR LLCInventor: Grant M. Lorang
