Absorption refrigeration device and refrigeration method for fishing boat

Abstract

The invention relates to a novel absorption type refrigeration device for fishing boats. The device comprises a generator and an absorber, and is characterized in that a circulating pipe is formed between the generator and the absorber through an input pipeline and an output pipeline; a heat exchanger is arranged on the input pipeline and the output pipeline; a pressure regulating valve is arranged on the output pipeline between the absorber and the heat exchanger; a solution pump is arranged on the input pipeline between the absorber and the heat exchanger; the generator is sequentially connected with a condenser, a gas-liquid separator, a refrigerating chamber, an injector, an evaporator condenser II and the absorber through a pipeline; and a throttling valve is arranged on a pipeline Ibetween the gas-liquid separator and the refrigerating chamber. The novel absorption type refrigeration device for the fishing boats provided by the invention has the beneficial effects that through the combination of driving through waste heat of an engine and replacing the throttling valve with the injector, the problem of electric drive energy consumption is solved; and meanwhile, a mixed refrigerant carries out auto-cascade cycle so as to produce the low temperature ranging from minus 20 DEG C to minus 30 DEG C required for refrigerating fishes, so that the device is energy-saving and environmentally-friendly, and has a better social benefit.

Description

technical field [0001] The invention relates to an absorption refrigeration device for a fishing boat and a refrigeration method thereof, belonging to the technical field of refrigeration. Background technique [0002] my country has a long coastline from south to north. There are tens of thousands of fishing boats in Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong along the coast. Almost all traditional fishing boats operating with ice are equipped with fishing boat refrigeration equipment. Fishing boat refrigeration is currently still using Double-click the compressed freon refrigeration system. Diesel generator sets are installed on board to supply the compressor motor. This energy consumption mode causes a lot of fuel consumption. On the one hand, it is a cost problem. On the other hand, about 30% of the heat of diesel engines on fishing boats is directly discharged from the exhaust gas. Atmospheric and fuel emission particulates cause environmental pollution....

AI Technical Summary

Problems solved by technology

[0006] The present invention overcomes the problems existing in the prior art, and proposes an absorption refrigeration device for fishing boats. The present invention can solve the problem of wasting energy consumption in the process of throttling by using an ejector, and at the same time, it can produce the temperature required for freezing fish at -20°C. - To -30℃-low temperature, energy saving and environmental protection
