    Abstract: Systems and methods for controlling temperature in an enclosed space can include an air-to-air heat exchanger (AAHX) and a direct evaporative cooler (DEC). The DEC can be located in a scavenger or outdoor air stream such that the DEC cools the outdoor air, which is then used to cool or reject heat from a process air stream passing through the AAHX. In an example, the AAHX can be a sensible wheel. In another example, the AAHX can be a counter-flow flat plate. The system can operate in various modes, including an economizer mode and an evaporation mode, depending, in part, on the outdoor air conditions and a load on the system. In some examples, the system can include a DX coil to provide additional cooling to the process air in another operating mode.

  • Publication number: 20110281516
    Abstract: An environmental control system of a building utilizes lower vents which open into lower portions of rooms of a building, and upper vents which open into upper portions of rooms of the building. When the system is operating in a heating mode, heated air is delivered into the upper portions of the rooms through the upper vents and air is removed from the rooms through the lower vents. When the system is operating in a cooling mode, cool air is delivered into the rooms through the lower vents, and air is removed from the rooms through the upper vents. Operating the heating and cooling modes in this fashion provides the most efficient operation of the heating and cooling system. A switching unit is used to selectively couple the inlet and outlet of an air handling unit to the upper and lower vents.

  • Patent number: 8021217
    Abstract: A self-contained pre-manufactured roof top unit is used to circulate fresh air, heat or cool a building. The housing has a blower connected into a circulation system to circulate air into and out of the building. The unit has a pressure relief opening for connection into the building that is used to relieve air pressure buildup within the building. The pressure relief opening is part of a pressure relief passage that is independent of the blower and has an exhaust vent that opens and closes automatically in response to pressure differential between the building and ambient air.
