Rotary heat engine

The engine consists of an annular array of chambers (hot leg), individually 5 connected to an adjacent continuous condenser (cold leg), and containing a quantity of working fluid and gas - the gas usually being the fluid's own saturated vapor. When a temperature differential exists between the chambers and condenser - either by means of heat being applied to the chambers or cooling being applied to the condenser, or both - a resultant difference in vapor pressure 10 is created; and while fluid within chambers on one lateral side is forced into the condenser, the positioning of the interconnecting ducts allows fluid to run freely from the condenser into chambers on the opposite upper lateral side. The weight imbalance and resultant torque created by such displacement of fluid causes the whole device to rotate, together with the axle to which it is secured.

RANKINE CYCLE START UP SYSTEM

HEAT PUMP OR REFRIGERATION DEVICE AND METHOD FOR OPERATING A HEAT PUMP OR REFRIGERATION DEVICE

In a method for operating a heat pump or refrigeration device (1), a coolant is isothermally compressed using a fluid displacement compressor (2), then cooled, optionally condensed in the process, and then expanded. In a next step, the coolant is evaporated and finally fed back to the fluid displacement compressor (2). In order to improve the efficiency of the process, it is proposed that heat from the cooled coolant following compression is transferred to the heated coolant before the coolant is returned to the fluid displacement compressor (2), and thus the cycle is closed, and that the coolant is expanded in an engine comprising an operative connection to a hydraulic pump (31) for pumping a hydraulic fluid of the fluid displacement compressor (2). Further proposed as an apparatus is a heat pump/refrigeration device for carrying out the above method.

During operation of the rotary valve assembly, the valve housing may permit fluid to enter the cylindrical bore of the valve housing via the inlet, the intake assembly may rotate to permit the fluid to flow through the at least one intake inlet port and the at least one throttle inlet port into the throttle body, and the intake assembly may permit the fluid to flow to the outlet from the throttle body.

Systems store energy mechanically at a first time and extract the energy at a later time. When excess electricity from renewable sources or during off-peak periods is available, a pump directs a working liquid (L) to pressurize a gas (G) that is confined within a pressure vessel. When electricity from renewable sources is not available or during periods of peak demand or pricing, the pressurized gas (G) directs the working liquid (L) through a hydropower turbine. The turbine drives a generator through a mechanical coupling to provide electricity for powering a load. In addition, the system can leverage (take) any waste heat as the input to boost the efficiency of the system. The described systems function at ground level and are modular and scalable in capacity.

Production of mechanical/electrical energy from heat energy with and by the use of buoyancy factor on evaporation or sublimation and condensation

There are various source of heat energy. Amongst the various sources Solar energy, waste heat form garbage, waste heat from transformers, waste heat from chemical reactions, waste heat from plant and machinery, heat from geo-thermal or the vast heat energy lying in the seas and oceans are some of the major ones which are free and unused. Apart from these, we can also produce heat energy from fuels like fossil fuels, hydrogen gas, forest products etc. A lot of heat energy is being wasted and though converted to mechanical or electric energy it is not that efficient. However, using the evaporation or sublimation and condensation process brought about through difference in temperature and the use of buoyancy factor to increase the efficiency of the energy production, the heat energy can be converted to mechanical or electrical energy in excess of hundred percent. Moreover, heat energy obtained from hydrolysis of some chemicals like salts or hydroxides and their dehydration for reuse or the heat stored as latent heat on melting of salts can be utilized for huge storage of energy for some months or more and use it through this invention method. The energy lying in the water under the oceans during winter can be easily utilized for production of huge energy when there are very low (freezing) temperatures on the surface of the earth.
