Cresent passage solution elevating vapor generator for absorption refrigerator with half-moon like pass

Abstract

The invention relates to channel with crescent cross-section to life solution and steam generator used in absorption refrigeration. The pipe composed of inner tube and outer tube is placed in cartridge heater. Dilute solution comes into slit shaped channel from button part of the pipe and strong solution is discharged out of the cavity for collecting high-pressure water vapor on the upper part. In the invented generator low-grade heat source can be utilized as well as solar energy to life solution from low spot to high place automatically, realizing self-circulation. The absorption refrigeration having the invented assembly exhibits notable merits of high effect, energy saving, safety, noiselessness, pollution free.

Description

1. Technical field [0001] The invention relates to a steam generator, in particular to a crescent-shaped channel solution lifting and steam generator in absorption refrigeration, which belongs to the subject field of engineering thermophysics and energy utilization. 2. Background technology [0002] The lithium bromide absorption refrigerator, which was born more than half a century ago, did not attract enough attention from the society at that time due to its low thermal coefficient. However, since the end of the 1960s, the world’s energy crisis has occurred. Especially in the 1980s, scientists discovered that Freon refrigerants, which once brought good news to mankind, have caused very serious damage to the atmospheric ozone layer on which human beings depend. , and is on the rise. At this time, people began to pay great attention to lithium bromide absorption refrigerators that can use low-grade waste gas as a heat source. [0003] The outstanding advantages of lithium b...

Problems solved by technology

[0005] Internationally, the United States and Japan have made long-term and in-depth research, and have developed small-scale solar-powered pumpless lithium bromide absorption air-conditioning systems, and a certain number have been put into operation, but their thermal coefficient is greatly affected by the temperature of the heating medium, and the temperature is too high. or too low will cause the thermal coefficient to decrease significantly

[0006] So far, my country has made some efforts in the research and development of small-scale pumpless lithium bromide absorption refrigerators, but has not been successful. The key is that it has not yet found a cooling machine that has a strong ability to lift the solution through thermosiphon action and has a strong ability to generate steam. innovative structure
