  • Patent number: 8813514
    Abstract: A Geothermal Rail Cooling and Heating System is a reversible system process that accelerates heat transfer between the steel rail used in railway track and the adjacent earth. It is comprised of the Rail Heat Exchangers specially shaped to fit tightly inside the rail web, a refrigerant cycling on its physical condensing and evaporative characteristics, a mechanical and power supply system, and an underground tubing loop system for heat dissipation or absorption. When the railroad track undergoes a range of temperature changes that results in rapid rail expansion, it may cause track buckling or sun kink. Upon detection of such occurrence, the system responds with cooling effect to slow down expansion, and simultaneously reduce the risk of track failure. By switching the direction of refrigerant flow utilizing the system built-in reversing valve, the function is alternated for the evaporator and condenser to enable heating instead of cooling.

  • Publication number: 20140190195
    Abstract: The invention utilizes concentrated solar energy in a novel air conditioning system which includes storage capabilities. The refrigerant circuit “high” pressure side is comprised of multiple solar concentrators placed between two positive rotary valves. The “low” pressure side is compromised of the evaporator coil with expansion valve. The refrigerant is confined between the two rotary valves. As solar energy is absorbed into the refrigerant, the pressure and temperature rise. The two rotary valves are then caused to rotate. With rotation, the refrigerant is moved through the circuit. The circuit also includes a condenser to give up heat and an evaporator/expansion valve in which temperature drops with the expanding gas. In addition, this system places the evaporator in a water tank. The water is made cold by conduction with the evaporator and serves as a storage medium. All energy absorbed is converted to cold and stored and utilized as required.
