  • Publication number: 20230044627
    Abstract: A heating, ventilation, and air-conditioning (HVAC) duct system which includes, at least in part, one or more modular, uniform, pre-manufactured duct elements having a uniform takeoff on one or more sides for connecting to a run to be connected to an air diffuser at the end. Each of the modular duct elements may include a built-in hanger support element so that the engineer merely has to design a very simple modular run of duct elements without unnecessary computations requiring different duct sizes. It also makes it simple and uniform for installing on site.

  • Patent number: 9835343
    Abstract: A system for controlling ambient temperatures of exposed structures using phase change materials and/or tempered liquid delivery systems. Phase change materials may be fabricated to hold the surrounding temperature at a desired temperature, such as 70 degrees Fahrenheit/21 degrees Celsius. As the heat load rises above this desired temperature, the heat is absorbed into the phase change material until that material has completely transitioned through its phase change, after which it will no longer absorb heat load. As the temperature then cools off at night, the heat is released from the phase change material, and the material changes back into its original phase. Phase change material may be placed within or on the exterior of stadium chairs. A liquid piping system may also be used to provide ambient heat control, including liquid piping for piping temperature-controlled liquid throughout the stadium while preventing condensation.
