Publication number: 20240263827Abstract: An air conditioning system including a conditioning unit (e.g., fan coil unit) and a control system are provided for efficiently and effectively conditioning indoor air. Some embodiments address temperature control (e.g., including heating and cooling), humidity control, and air quality control, while also introducing conditioned outdoor air. One aspect relates to a control system that delivers liquid to a coil in the conditioning unit at a specified input temperature and flow rate (or specified input temperature and temperature drop across the coil) to meet both sensible and latent cooling demands.Type: ApplicationFiled: February 2, 2024Publication date: August 8, 2024Applicant: FT Energy Controls, LLCInventors: Richard C. Furman, Zachary M. Thomas

Patent number: 11768006Abstract: A control system is provided for controlling heating and/or cooling with a conditioning load such as fan coils and chilled beams. Based on user input and ambient conditions, the control system determines a desired temperature for the liquid entering the load and combines fresh supply liquid (e.g., from a chiller or boiler) with a portion of the liquid that has passed through the load, to achieve the target load input temperature for the liquid. A recirculation pump may be used to return a portion of the liquid exiting the load for mixing with the fresh supply liquid and a control valve may be used to adjust the ratio of fresh supply liquid and recirculated liquid to achieve the targeted temperature. The control systems can be compatible with a variety of liquid supply systems such as two- and four-pipe systems.Type: GrantFiled: October 6, 2022Date of Patent: September 26, 2023Assignee: FT Energy Controls, LLCInventors: Richard Furman, Zachary M.

Publication number: 20230221031Abstract: A system and terminal unit are provided for efficiently and effectively conditioning indoor air. Some embodiments address temperature control, humidity control, air quality control, while also introducing conditioned outdoor air. One aspect relates to a terminal unit that monitors and controls sensible and latent cooling rates to simultaneously meet temperature and humidity setpoints for the conditioned space. A sensor suite provides measurements for monitoring cooling rates and a control system controls actuators to meet the sensible and latent cooling requirements. The terminal unit may have a secondary recirculation air intake that bypasses the cooling coil to warm supply air prior to exiting the terminal unit. The terminal unit may be part of an air conditioning system where it is connected to a main branch of a hybrid branch controller which avoids having a home run to the HBC for each terminal unit.Type: ApplicationFiled: January 11, 2023Publication date: July 13, 2023Applicant: FT Energy Controls, LLCInventors: Richard C.
