ABSTRACT:
Apparatus and method are disclosed for controlling fluid delivery into a heat exchanger wherein the temperature and the pressure of the delivered fluid is lower than the temperature and the pressure of the fluid within the heat exchanger and wherein the delivery of the fluid is accomplished without the use of pumps or compressors or other such devices. The delivering apparatus uses the pressure force developed within the heat exchanger after fluid change of phase has occurred therein for delivering the fluid vapor resulting therefrom to an elevation superior to the delivering apparatus by means of a predetermined elevated position of the pressure driven device using the vaporized fluid for its operation and the disposition of the conduit delivering the exhaust therefrom. The exhausted fluid is returned to the liquid condition by means of the heat and pressure expended in operating the pressure driven device and, by additional cooling, if needed. Means are provided for automatically returning the condensed liquid fluid to the heat exchanger by alternately isolating and pressurizing the fluid in alternative containers wherefrom the fluid is delivered in a compound manner into an additional container for further subjection to pressure equalization and controlled delivery into the said heat exchanger. This is accomplished in a closed system on a continuous basis with the energy force above described as the sole source of energy required to continue the cycle with the exception of an insignificant amount of electricity used to operate the solenoid control devices.
