ABSTRACT:
A heating and air conditioning system and method involves the use of turbomachinery and a working fluid capable of changing phase at specific temperature and pressure and powered by an external heat source. The pressure of a portion of the working fluid in liquid form is increased and thereafter heated to change phase to a gas for use as a high energy working fluid component which is flowed through the turbo-drive. Another portion of the working fluid, at an intermediate pressure is expanded to a lower pressure and then passed through an evaporator, whose output forms a low energy working fluid component in gas form. The low energy working fluid is flowed into the turbo-device for admixture with the high energy working fluid, to effect an energy exchange therebetween. The turbo-device includes an output which is condensed and at an intermediate pressure. Various systems, turbo-devices and working fluids are described.
