    摘要： A centrifugal heat pump system includes a steam system with a steam supply, a steam turbine and a steam condenser connected in a steam loop; and a refrigerant system including a first compressor and a second compressor, a refrigerant condenser, and an evaporator connected in a refrigerant loop. The steam turbine includes a rotary drive shaft disposed axially and extending from a first end and a second end of the steam turbine. A sump system collects and redistributes oil or other lubricating fluid. The first compressor is coupled by a first coupling device to the first end of the steam turbine drive shaft and the second compressor is coupled by a second coupling device to the second end of the steam turbine drive shaft. The first and second compressors are connected in parallel in the refrigerant loop and controlled to share a cooling load equally.

    摘要： A thermodynamic power system has a low-temperature closed bottoming cycle using a first working fluid (first gas) and open or closed modified Brayton topping cycles using a second working fluid (second gas). In the bottoming cycle a mixture of a first gas such as helium or hydrogen and a fine dispersed low-temperature non-freezable lubricating liquid is polytropically compressed in a compressor and then the liquid content is separated from the first gas. The separated first gas is isobarically heated using heat from the second gas and then the heated first gas is adiabatically expanded and cooled while performing useful work and thereafter is fed to the compressor and mixed with the separated liquid to serve as a coolant and facilitate rejection of polytropic heat and to supplement the cool gas/liquid mixture providing polytropic compression of the first gas and thus completing the bottoming cycle. The low-temperature bottoming cycle functions to cool the second working fluids of the open or closed modified Brayton topping cycles before their compression. The power system using a high temperature heat source can generate a large amount of specific power to achieve a high actual thermal efficiency greater than 0.8.

    摘要： A cooling system operated by a pair of turbines on the same drive shaft. Some of the hot exhaust fluid from both turbines goes through corresponding heat exchangers to a condenser and from the condenser back through these heat exchangers and a heater to inlets to the turbines. The remainder of the hot turbine exhaust fluid flows through a pressure regulating valve to an additional heat exchanger and from there through a condenser to several evaporators, which are connected in parallel, and from these evaporators through a pressure regulating valve back through the additional heat exchanger and a compressor to inlets to the turbines.

    摘要： This invention embodies improvements in evaporative type refrigeration and space cooling units, both as to energy conservation and efficiency and economy of operation. It utilizes the new abentropic principle as set forth in my U.S. Pat. No. 4,109,470, which demonstrates that the energy of the latent heat of vapor is potential energy and need not be discarded as is done in present practice but can be converted to mechanical energy by taking advantage of the fact that the vapor pressure exuded by boiling hot condensate is the same as that of the vapor itself. The difference between this vapor pressure and that of a hard vacuum is sufficient to drive an engine. The energy necessary for the work done is extracted from the latent heat of the incoming vapor causing some of the vapor to condense at its boiling point proportionately as the work proceeds. Herein, a combination turbine and abentropic engine system is used to extract energy from the pressurized vapor and condense it to the liquid state, while assisting the work of the turbine.
