| 142 | SYMMETRICAL INTERMEDIATE STORAGE MEANS FOR HEAT PUMPS WITH CYCLICAL DRAINAGE INTO A MAIN SYSTEM | US13391286 | 2010-08-11 | US20120144853A1 | 2012-06-14 | Michael Loeffler |
| Heat pumps and refrigerating machines operate optimally if the temperature difference of the connected heat sources and heat sinks is as small. If this is not the case, there are two negative effects: At a high spread, increased dissipation occurs in the condensers and evaporators. In order to increase spread, the heat return flow is frequently mixed with the heat pump flow. For this purpose, hydraulic separators and overflow valves are employed. This results in highly dissipative mixing of heat carrier medium with differing temperatures. Using a pair of intermediate storage means, the dissipation that occurs can be drastically reduced. The low spread of the heat pump is adjusted to the high spread of the remaining system. The COP of the system is substantially improved. With heat pumps, the improvement ranges from about 5% to 20%. | ||||||

| A heat transfer device is described that can be operated as a heat pump or refrigerator, which utilizes a working fluid that is continuously in a liquid state and which has a high temperature-coefficient of expansion near room temperature, to provide a compact and high efficiency heat transfer device for relatively small temperature differences as are encountered in heating or cooling rooms or the like. The heat transfer device includes a pair of heat exchangers that may be coupled respectively to the outdoor and indoor environments, a regenerator connecting the two heat exchangers, a displacer that can move the liquid working fluid through the heat exchangers via the regenerator, and a means for alternately increasing and decreasing the pressure of the working fluid. The liquid working fluid enables efficient heat transfer in a compact unit, and leads to an explosion-proof smooth and quiet machine characteristic of hydraulics. The device enables efficient heat transfer as the indoor-outdoor temperature difference approaches zero, and enables simple conversion from heat pumping to refrigeration as by merely reversing the direction of a motor that powers the device. | ||||||

| A heat pumping process for the generation of industrially useful heat energy achieves an improved fuel effectiveness by feeding back to the process part of its otherwise output heat energy as an input to assist in compressing the process evaporized performing fluid. An equivalent amount of extraneous fuel otherwise required to carry out the mechanical work now done by the fed back energy is thus replaced. | ||||||
| 151 | Energy conversion method with water recovery | US910098 | 1978-05-30 | US4282070A | 1981-08-04 | Dan Egosi |
| A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200.degree.-400.degree. C. The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam. The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection. The compressor is driven by a heat engine whose reject heat is collected and upgraded as well. The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone. | ||||||
| 152 | Heat pump | US918234 | 1978-06-23 | US4197715A | 1980-04-15 | Sherwood L. Fawcett; James N. Anno |
| Heat pump apparatus employing a continuous loop passageway containing a plurality of freely-movable, unrestrained bodies. The bodies are accelerated around the passageway in one direction by adiabatic expansion of a fluid between the bodies in an expander region of the passageway. The expanded, cooler fluid is discharged from the passageway via one or more vent-intake ports in the passageway beyond the expander region. Warmer fluid enters the passageway via said ports and is compressed between the propelled bodies in a compression region of the passageway, thereby raising its temperature from a first temperature (e.g., the temperature of the outdoor atmosphere or an industrial waste heat stream) to a second temperature higher than the first. The compressed, warmer fluid is thereafter passed through a heat exchanger to extract heat. In passing through the compression region the bodies are decelerated and they then pass through a thruster region of the passageway wherein a force is applied to the bodies to counterbalance the external forces acting against the bodies as they move around the loop passageway. From the thruster region the bodies pass to the expander region to repeat the cycle. From the heat exchanger the fluid, typically together with additional compressed fluid from an external source, is introduced into the expander region to again accelerate the bodies. | ||||||
| 153 | Heat engine and heat pump utilizing a working medium undergoing solidification and melting operations | US474317 | 1974-05-29 | US3953973A | 1976-05-04 | Chen-yen Cheng; Sing-Wang Cheng |
| The present invention introduces a heat engine, or a heat pump, in which the working medium used is subjected alternatively to solidification and melting operations. A working medium so used is referred to as an S/L type working medium. In a new heat engine, an S/L type working medium is subjected to cyclic operations, each cycle comprises of a high temperature melting step conducted under a first pressure, and a low temperature solidification step conducted under a second pressure. In a new heat pump, each cycle comprises of a high temperature solidification step conducted under a first pressure and a low temperature melting step conducted under a second pressure. When a non-aqueous medium is used, the first pressure and the second pressure are a relatively high pressure and a relatively low pressure, respectively. When an aqueous medium is used the two pressures are a relatively low pressure and a relatively high pressure, respectively. it is noted that the operation of a heat pump is the reverse operation of a heat engine. | ||||||

| A manually actuated heat pump particularly suited for use as an auxiliary device in selectively warming and cooling an ambient medium, characterized by a pair of abaxially related, independently mounted rotatable hubs, interconnected through a plurality of elastomeric bands extending between the peripheries of the hubs and which, upon being rotated, achieve alternating elongation and contraction for the bands, whereby the bands cyclically are caused to experience a continuously reversing heat transfer process, in accordance with the principles of the socalled Joule effect in rubber, for selectively delivering and extracting heat energy from an ambient atmospheric medium, a feature of the pump being an employment of a fluid bath which receives therein the bands in selected states of elongation for effecting a heat transfer between the fluid of the bath and the bands whereby a selective preheating and precooling of the bands are achieved in a medium divorced from the ambient atmosphere for thus controlling the reversibility of the transfer of energy within the atmosphere.

| A four-process cycle is disclosed for a Vuilleumier heat pump that has mechatronically-controlled displacers. Vuilleumier heat pumps that use a crank to drive the displacers have been previously developed. However, mechatronic controls provides a greater degree of freedom to control the displacers. The four-process cycle provides a higher coefficient of performance than prior cycles in the crank-driven Vuilleumier heat pump and those previously disclosed for a mechatronically-driven Vuilleumier heat pump. | ||||||
