Split solid adsorption cooling system

Номер: US20120006049A1
Автор: Chao-Yu Chen, Chi-Bin Wu, Ting-Kuan Li, Yu-Ming Sun
Принадлежит: Chung Hsin Electric and Machinery Manufacturing Corp

A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger. While adsorption and desorption take place alternately in the first and the second adsorption units, the temperature of the first and the second pipelines is lowered, thereby decreasing the temperature of water flowing in the shell-and-tube heat exchanger. In addition, the manufacturing costs of the split solid adsorption cooling system can be lowered because the shell-and-tube heat exchanger need not be operated in a vacuum environment. Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced.

High efficiency heat pump combining absorption and solution concentration change. The method gives a few times higher efficiency for heat transfer applications like heating—air conditioning. It is a heat and mechanical compression method using liquid electrolyte solutions, combining steam absorption, solution concentration change and mechanical compression. There is no heat consumption. Steam condensation is performed by a high concentration solution and vaporization from a low concentration solution reducing in this way the required mechanical compression of the known refrigeration cycle. The method may be used for work production too, exploiting moderate temperature heat sources. 1. Method for working fluid compression for heat transfer from a lower to a higher temperature heat sink using a heat compression absorption pump where the working fluid is a solution of substances in a liquid solvent which is partially vaporized and then condensed and the absorption solution concentration changes by absorption solution temperature lowering so as part of the absorbent is separated , characterized by the fact that the absorbent separation from the absorber leaving solution , takes place without energy consumption , the heat rejection from the concentration lowering solution is fully recovered , the absorber solution is concentrated and at high absorbent concentration. The method works effectively at high , at a range of 1/10 or higher , absorber/generator concentration ratio and activities ratio. Temperature lift may be high , in the range of 150-200° C.

In an energy conversion method and a thermal power plant for converting heat into mechanical or electric energy using a working medium, a vapor state in the working medium is generated at a first pressure in a steam generator. The vaporized working medium is expanded to a lower second pressure in a steam expanding device. An energy obtained by the expansion process is discharged. The expansion of the steam state is carried out using a saturation line of the working medium. The working medium is thereby separated into a non-condensed portion and a condensed portion in a separating device. The non-condensed portion is then compressed into a compressed non-condensed portion in a compressor. The compressed non-condensed portion is cooled and condensed into a compressed condensed portion.

An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.
