Absorption refrigerating machine

Abstract

The invention provides a Absorption refrigerating machine, which can improve heat recovery efficiency of heat fluid that flows over the absorption refrigerating machine based on a structure of few components and simplified piping, particularly, can improve heat recovery efficiency of potential heat of heat fluid based on a structure of miniaturized heat recoverer that recovers heat from the heat fluid that flows over a high temperature regenerator. In the absorption refrigerating machine, a diluted absorption liquid tube through which the diluted absorption liquid flows from the absorption device to the high temperature regenerator is divided into a first diluted liquid tube and a second diluted liquid tube; in the first diluted liquid tube, heat fluid communicates the high temperature regenerator, the first heat recoverer, a steam trap and a second heat recoverer; the second diluted liquid tube is provided with a high temperature heat exchanger that exchanges heat with intermediate absorption liquid generated in the high temperature regenerator and a low temperature heat exchanger that exchanges heat with concentrated absorption liquid generated in the low temperature regenerator.

Description

technical field [0001] The invention relates to an absorption refrigerator (including an absorption cold and warm water machine) for freezing / air conditioning, in particular to a dual-effect absorption refrigerator for steam incineration. Background technique [0002] All along, with the increasing concern about the temperature of the earth's environment, the demand for higher efficiency of machines has been increasing. In particular, this tendency is remarkable in cooling and heating facilities and commercial facilities in regions where the operating hours are long, and improvement in machine efficiency is desired. [0003] And in response to this demand, a technique for improving the heat recovery efficiency from the heat source fluid flowing through the absorption refrigerator has been proposed (for example, refer to Patent Document 1). [0004] However, in this technique, the dilute liquid pipes that flow the dilute liquid supplied from the absorber to the high-temperat...

Problems solved by technology

[0008] However, the structure of Patent Document 2 requires a high-pressure design for the steam pipe through which the heat source fluid flows and the heat recovery device for recovering heat from the heat source fluid, which raises the problem of increased manufacturing costs.
