摘要:
In a chemisorption reaction process wherein a polar gas is repeatedly alternately adsorbed and desorbed on a complex compound formed by adsorbing said polar gas on a metal salt, said complex compound capable of having a first density if allowed to expand without restriction during said adsorption, a method of increasing the reaction rates of said chemisorption reaction process comprises controlling the volumeric expansion of said complex compound formed during at least the initial adsorption reaction of said polar gas on said metal salt to form at least a partially structurally immobilized, self-supporting, coherent, reaction product mass having a second density. The metal salt may also be mixed with a zeolite, activated carbon, activated alumina or silica gel prior to the first adsorption reaction. In another embodiment, the polar gas is used initially to form a complex compound with the salt and thereafter desorbed and a nonpolar gas used for being adsorbed and desorbed on the zeolite, activated carbon, activated alumina silica gel, or metal hydride.

A system for storing chemical energy comprises first and second vessels, the first containing a liquid solution of an alkali or alkaline earth metal hydroxide, halide, or thiocyanate, or ammonium halide or thiocynate at an initial concentration of between about 30% to abotu 80%, by weight, the second vessel containing liquid, a space about the liquid in each vessel and a conduit communicating between the spaces having a valve for selectively allowing liquid vapor to pass between the spaces, means for heating the solution to a temperature above about 80.degree. F., means for cooling the liquid to a temperature below about 55.degree. F., and heat exchange means for transferring heat from the heated solution and for transferring heat to the cooled liquid. Water is the preferred liquid although ammonia, lower alcohols, and polyols such as glycerol, glycols, polyglycols, glycol ethers, lower aliphatic amines and alkanol amines, and mixtures thereof, may be used.

An improved heat exchange system incorporates the cooling created by using a metal salt/ammonia ligand complex compound which is alternately heated and cooled to alternately desorb and adsorb, respectively, the ammonia creating useful cooling or refrigeration in the temperature range of between -65.degree. C. to 15.degree. C.
摘要:
A wall plug anchor assembly is provided including a sleeve, a spherical body for flaring anchoring ends of the sleeve which body is inserted from a head end of the sleeve into an unslotted portion thereof, and a driver. By means of the driver, the spherical body is forced forward against concrete material which has entered into the sleeve interior. The operative end of the driver includes a wedge surface by and over which the spherical body can be laterally displaced away from a central axis of the sleeve in a direction of the sleeve walls in a wedge-induced or clamping movement.
摘要:
Energy and mass are transferred in a system utilizing a gaseous refrigerant which is mixed and sorbed (absorbed/adsorbed) with a liquid carrier selected from the group consisting of long chain alcohols, ethers, glycols, glycol ethers, sebecates, phthalates, aldehydes and ketones, the sorbate/liquid mixture then combined with a particulate solid capable of forming a solid/gas compound with the gaseous refrigerant. The process is carried out in a mass and heat exchange apparatus capable of collecting and transferring the energy created by the formation or dissociation of the solid/gas compound.

A microgrid controller may control the generation, distribution, storage and use of electrical power on a microgrid. Embodiments of a microgrid controller may include inputs for different types of power (e.g. AC and DC) or power sources (e.g. wind and solar), an input for utility grid power, electrical equipment for conditioning the electrical power received from the multiple sources (e.g. rectifiers and inverters), outputs to multiple types of loads (e.g. three-phase AC and single-phase AC) and control circuitry designed to control the generation, storage, distribution and usage of electrical power on the microgrid. Embodiments of microgrid systems may include multiple types of electrical generation sources (e.g. wind, solar, electromechanical and fuel cell), multiple types of electrical loads (e.g. inductive and resistive), electrical storage units (e.g. batteries) and a microgrid controller.
摘要:
A thermal energy battery for cooling temperature sensitive components comprises a composite of a sorbent with ammonia, water, alcohol, amine or a fluorocarbon refrigerant absorbed thereon and incorporated on a substrate material. The composite is encased in a containment material configured to rupture or otherwise release refrigerant desorbed by the sorbent composition when internal battery pressure reaches a threshold ΔP from the outside pressure, and thermal conduction means in thermal contact with the thermal energy battery and one or more temperature sensitive components for directing thermal energy therebetween to heat the composite and cool the temperature sensitive components.

A cascade heat pump system is configured with variable-speed compressors which allow operation at a high system coefficient of performance for a given thermal load. An electronic control module may be utilized to dynamically vary the speed of the compressors to achieve maximum energy efficiency. Variable-speed fans or blowers may also be used.
