Embodiment Construction

[0011] The present invention has the first adsorption-desorber 1, the second adsorption-desorber 2, the condenser 7, the component separation module 8, the second throttling device 9, the second regenerator 10, and the first regenerator connected in sequence. device 11, first throttling device 12 and evaporator 13, solid adsorbent is housed in the first adsorption-desorber 1 and the second adsorption-desorber 2.

[0012] The end of the pipeline connected to the first port 18 of the condenser 7 is divided into two paths: the one branched from the end of the pipeline connected to the first port 18 of the condenser 7 passes through the first valve 3 and the first of the first adsorption-desorber 1. Port 14 links to each other, and the other way that the pipeline end that is connected with the first port 18 of condenser 7 is connected with the first port 16 of the second adsorption-desorber 2 through the third valve 5, the second port 19 of condenser 7 Be connected with the first ...

Abstract

Present invention discloses a mixing working medium deep refrigeration deep refrigeration adsorption refrigerator. It in turn connected first sorption / desorption unit, second sorption / desorption unit, condensator, constituent element separation module, second throttling set, second thermal regenerator, first thermal regenerator, first throttling set and evaporator, solid sorbent installed in first sorption / desorption unit and second sorption / desorption unit. Said invention applies self overlapping mixing working medium refrigerator principle to adsorption refrigeration system to fully utilize different kinds of high low temperature waste heat low temperature waste heat low temperature waste heat, to simplify tradition overlapping type adsorption refrigeration system realizing -60 to -200 degree centigrade deep refrigeration with simple structure, reliable performance, and high efficiency.

Description

technical field [0001] The invention relates to an adsorption refrigeration device, in particular to a mixed working fluid deep freezing adsorption refrigeration device. Background technique [0002] Solid adsorption refrigeration is a heat-driven refrigeration method that can use low-grade energy such as waste heat, geothermal heat, and solar energy, and can use refrigerants that have no damage to the atmospheric ozone layer. It is an environmentally friendly refrigeration method. Since the 1970s, the worldwide energy crisis has promoted the rapid development of adsorption refrigerators, which have broad application prospects in today's increasingly tense petroleum energy. [0003] So far, simple single-stage adsorption refrigeration systems are generally only used in temperatures above -40°C. To achieve deep refrigeration below -60°C, a cascade adsorption refrigeration system is required, or an adsorption refrigeration system cascaded with other refrigeration systems (her...
