Abstract

The invention discloses an absorption refrigeration system based on a vortex tube and a working method thereof, wherein an absorption refrigeration system based on a vortex tube includes a generator, a condenser, a gas-liquid separator, a first regenerator, a first section Flow valve, evaporator, vortex tube, absorber, second solution regulating valve, solution pump, solution heat exchanger, second regenerator and third throttle valve. The introduction of the vortex tube in the present invention can effectively reduce the throttling loss of the refrigeration cycle, which is beneficial to improve the cycle refrigeration efficiency; the high-temperature gas at the hot end of the vortex tube can be reused to improve the performance of the new absorption refrigeration cycle, that is, the high-temperature gas at the hot end of the vortex tube is used for preheating Refrigerant-rich liquid from the solution heat exchanger; use the cold end gas of the vortex tube to subcool the refrigerant liquid from the vapor-liquid separator to make it a supercooled liquid, further effectively reducing the temperature of the solution entering the absorber, which is conducive to improving Refrigeration cycle performance.

Description

Technical field [0001] The invention relates to an absorption refrigeration system, in particular to an absorption refrigeration system and a working method based on a vortex tube. Background technique [0002] With the rapid development of social economy, a large amount of waste heat will be released in the production process of bioengineering, pharmacy, food processing and chemical industry. The waste heat resources are sufficient, but the energy density is low and the energy utilization rate is low, causing energy waste and environmental pollution. [0003] The absorption refrigeration cycle has high heat conversion efficiency, and can effectively use low-grade energy such as solar heat, geothermal heat, and a large amount of waste heat generated in the industrial production process to produce the required cooling capacity, which can effectively save high-grade electrical energy. However, the traditional absorption refrigeration system has the disadvantages of low refrigeration ...
