Abstract
A thermally driven heat pump includes a low temperature evaporator for evaporating cooling fluid to remove heat A first heat exchanger located at an outlet of a converging/diverging chamber of a first ejector receives a flow of primary fluid vapor and cooling fluid vapor ejected from the first ejector for condensing a portion of the cooling fluid vapor An absorber located in the first heat exchanger absorbs cooling fluid vapor into an absorbing fluid to reduce the pressure in the first heat exchanger A second heat exchanger located at an outlet of a converging/diverging chamber of a second ejector receives primary fluid vapor and cooling fluid vapor ejected from the second ejector for condensing the cooling fluid vapor and the primary fluid vapor A separator in communication with the second ejector, the low temperature evaporator and the primary fluid evaporator separates the primary fluid from the cooling fluid.
