417,909. Refrigerating. MAIURI REFRIGERATION PATENTS, Ltd., Bush House, Aldwych, London. Feb. 6, 1934, No. 3857. Convention date, June 9, 1933. [Class 29.] Absorption machines and systems.-The weak liquor is distributed over the cooling coil a of the absorber by a wick f preferably formed of two superposed gauze sheets doubled over to form a syphon. Any desired number of coils and wicks or syphons may be provided in a single absorber. Further, similar liquid distributing means may be employed in the evaporators and generators of absorption refrigerating machines. Fig. 3 shows the invention applied to the absorber A, reabsorber B, generator C, and evaporator D of a reabsorption machine employed, e.g. for cooling brine flowing through the evaporator coil d and heated, e.g. by the flow of hot water from the economiser of a boiler plant through the generator coil c. Liquid is circulated between the vessels by pumps P, P which may be replaced by a common pump. Further, the single coils in each of the vessels may be replaced by two separate superposed coils through the upper of which is circulated the liquid that has already passed through the vessel. The pressures in the vessels A, D and C, B may be equalised by inert gas. Dichlorethylene and ethyl chloride may be employed as refrigerants and paraffin and fusel oil as the corresponding absorbents.

The system comprises a plurality of first fluidic flow channels and a distribution device fed by a flow of a first fluid, notably a liquid, and injecting the flow of first fluid into the plurality of first channels at an output of the distribution device. The output of the distribution device consists of an distribution element for the first fluid, notably formed in a porous material, configured in such a way as to be passed through by the first fluid with a pressure drop such that the first fluid leaves from the distribution element with a uniform surface distribution at an output surface of the distribution element, in a way that ensures a uniform feed of first fluid for the first channels.

A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.

Heat pumps, refrigeration machines, heat transformers and the like which function on the resorption principle using a binary working medium, especially a mixture of ammonia and water, operate with two solvent circuits in which the working medium that is in the liquid phase is raised from a lower to a higher pressure level and expanded back to the lower pressure level, an interconnecting conduit existing between the solvent circuits on the low-pressure side and high-pressure side in which vaporous working medium is exchanged. To compensate for differences occurring during operation in the volume and concentration of the working medium in the two circuits, a compensating conduit for flowing liquid working medium of different concentration is provided parallel to one of the two conduits for the vaporous working medium. The volumetric flow of the liquid working medium flowing in the compensating conduit is regulated from a central computer unit in accordance with the concentrations of the vaporous working medium flowing in the conduits between the solvent circuits and the volume of the vaporous working medium flowing in one of the conduits, and the concentration of the liquid working medium flowing in the compensating conduit.
摘要:
High, intermediate and low pressure stages are provided in a thermal machine including sealed chambers permitting maintenance of respective pressures but permitting flow of vapor from one vessel to a second within a stage and providing for the flow of an absorbent solution among the vessels in different stages. The intermediate stage includes resorption and regeneration vessels which are thermally coupled, respectively, to a generation vessel and an absorption vessel in the high and low pressure stages, so that a variable fraction of the absorber heat may be transferred to the regenerator and of the resorber heat to the generator. The name Variable Effect refers to this variable internal heat transfer which permits the machine to adjust to a wide range of available heat source and heat rejection temperatures while maintaining high efficiency. Heats are accepted by and rejected from the generator and absorber over large ranges of temperature, which permits small pump and fan power and provides good utilization of the heat source and sink. Several versions of the machine, some including an evaporator and a condenser and others including a power convertor, and using fluids selected for each purpose, may be applied to heat pumping, chilling, temperature amplification, power production and desalination or other separation processes.
摘要:
A sorption heat pump including a fuel energized discharge unit from which heated fluid media for the heat pump is provided and a circuit having the fluid media circulated therethrough and arranged to include a heat exchanger, an absorber, pump devices, a temperature level changer and an energy consumption circuit. The discharge unit operates to emit the fluid media into the circuit as a heated weak solution and to receive the fluid media returned from the circuit as a rich solution. The discharge unit also produces an overheated vapor. The temperature level changer comprises a first and a second heat exchange unit, with the first unit being directly connected to the discharge unit to receive the weak solution therefrom, with the first unit also being connected to form part of a supply line for the energy consumption circuit. The second heat exchange unit of the temperature level changer is connected to return rich solution to the discharge unit and it is also connected to receive the overheated vapor from the discharge unit.
