  • Patent number: 11499760
    Abstract: The HVAC On Demand Via High And Low Pressure Vortex Separation Apparatus With Rotating Spin Chamber is a novel heating and cooling system that could revolutionize the HVAC industry. The instant invention takes in ambient air, via ducted fans, and separates hot and cold air by spinning the air molecules into a self-contained vortex. Specifically, it allows the less dense hot air molecules to pass through the front of the invention while diverting the cold air molecules through a series of reversing tubes to exit the apparatus. As the main rotating spin chamber spins ambient airflow into a centrifugal vortex in one direction, the air inlet tubes are positioned in such a way that it allows the rotating spin chamber to revolve in the opposite direction of the interior vortex. This captures all mechanical energy on the inside and outside of the vortex. The apparatus takes otherwise wasted mechanical energy and converts it into additional electrical energy.

    Abstract: An air conditioning system includes a dehumidifier, a regenerator, and a refrigeration system. The dehumidifier removes water from a first airflow using a liquid desiccant. The regenerator transfers water from the dilute desiccant into a second airflow. The refrigeration system can be selectively used to provide heat to the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. An external heat source can also be used to heat the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. The refrigeration system and the external heat source can each be used separately to heat the desiccant, or the desiccant can be heated by both heat sources simultaneously.

    Abstract: In at least one aspect of this disclosure, a refrigeration system includes an evaporatively cooled condenser configured to transfer heat from the refrigeration system to an atmosphere, an air inlet in fluid communication with the condenser, and an evaporative cooling medium disposed between the atmosphere and the condenser such that at least a portion of an airflow from the atmosphere passes through the evaporative cooling medium to reduce the temperature of the airflow before passing the airflow over the condenser. The evaporative cooling element can improve system cooling efficiency by 20-50% depending on temperature conditions or even greater in dry climates.

  • Patent number: 8763417
    Abstract: The refrigeration system of this invention utilizes a water cooled condenser which is made of multiple water pans with refrigeration coil soldered underneath for multi-stages cooling. The water pans are stacked on top of each other with the hottest coil located at the bottom. The bottom water pan dries up water faster than the other water pans since it has the hottest coil soldered underneath. Once the water level of the bottom water pan is low enough to be refilled, the supply water fills in from the top water pan and propagating downward to the water pan down below until it reaches the water pan at the bottom. The water refilling ceases once the bottom water pan is full. The unwanted heat from a refrigeration system is transferred from the refrigerant to the water, and then from the water to the air by evaporation.
