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.

Patent number: 10932420Abstract: A system includes a latent exchanger and first and second fans. The latent exchanger includes first and second chambers and one or more membranes separating the first chamber from the second chamber. The one or more membranes are gas-impervious. The first fan generates a greenhouse airflow that flows from a greenhouse, into the first chamber, and then back to the greenhouse. The second fan generates an outside airflow that flows from an outside environment, into the second chamber, and then back to the outside environment. The one or more membranes are configured to permit moisture to flow through the one or more membranes from the greenhouse airflow to the outside airflow through the one or more membranes and to prevent carbon dioxide from flowing through the one or more membranes from the greenhouse airflow to the outside airflow.Type: GrantFiled: April 19, 2018Date of Patent: March 2, 2021Assignee: Therma-Stor, LLCInventors: Todd R.
