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. The entire invention along with understanding how air separation on a molecular scale works, allows the invention to be scaled to any size and configuration for an incredibly high efficiency rate.

A method for efficiently reducing the energy required to convert natural gas from a natural gas pressure letdown facility at high pressure and pipeline/wellhead temperature to liquid natural gas in close proximity to/collocation with a natural gas pressure letdown/regulation facility using Non-Freezing Vortex Tubes (U.S. Pat. No. 5,749,231) in arrangement with indirect contact heat exchangers. The Non-Freezing Vortex Tubes separate the inlet natural gas into hot flow and cold flow outlet natural gas flows. One portion of the natural gas flow from the high-pressure transmission line/gas wellhead is directed through the Non-Freezing Vortex Tube and the cold outlet flow of the natural gas is directed to the indirect contact heat exchanger(s) to act as the cooling medium. The liquid natural gas plant's required natural gas flow is directed at the existing pipeline/wellhead gas pressure through the heat exchanger and cooled. The already cooled natural gas flow is directed to a turbo expander and refrigeration cold box system where it is further chilled and converted into liquid natural gas at −162° C.

A temperature-control device (1) is provided for controlling the temperature of a prober table (110) for semiconductor wafers and/or hybrids. The device has a fluid inlet (10) for introducing a temperature-control fluid into the temperature-control device (1) and a first heat exchanger (20) for preliminary control of the temperature of the temperature-control fluid that is introduced. A second heat exchanger (30) is used to control the temperature of the temperature-control fluid. The temperature-controlled temperature-control fluid can be conducted to the prober table (110) through a prober temperature-control line (40). A return circuit (60) is configured, so that upon receiving a return switch signal, the return circuit (60) selectively either conducts a temperature-control fluid returned from the prober table (110) through the first heat exchanger (20) or allows the temperature control fluid to flow out bypassing the first heat exchanger (20).
