The invention discloses an evaporator and a refrigerating system. The evaporator comprises an outer sleeve, a hydrogen inlet pipe and a liquid ammonia pipe, wherein the outer sleeve is used for mixing hydrogen with liquid ammonia, the hydrogen inlet pipe is internally hidden in the outer sleeve, and the gas outlet end of the hydrogen inlet pipe is arranged at the closed end of the outer sleeve; the liquid ammonia pipe is internally hidden in the outer sleeve, and the gas outlet end of the liquid ammonia pipe is arranged at the closed end of the outer sleeve; and the outer sleeve, the hydrogen inlet pipe and the liquid ammonia pipe are all horizontally arranged, the diameter of the outer sleeve is gradually increased along the air inlet direction of the hydrogen inlet pipe. Hydrogen enters the outer sleeve through the hydrogen inlet pipe, the liquid ammonia enters the outer sleeve through the liquid ammonia pipe, when the hydrogen is mixed with the liquid ammonia and the liquid ammonia flows out of the outer sleeve from the end, far away from the gas inlet end, of the hydrogen inlet pipe, of the liquid ammonia, due to diminishing of the diameter, the emission of ammonia gas is reduced, so that a large amount of ammonia gas is retained in the outer sleeve pipe to absorb the heat of air outside the outer sleeve pipe, and then the heat absorption efficiency is improved.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, especially an evaporator and a refrigeration system. Background technique [0002] At present, the refrigerant vapor turns into liquid ammonia after passing through the cooler and enters the evaporator. In the current evaporator, the refrigerant ammonia flows away quickly in the evaporator. The liquid ammonia cannot fully evaporate and absorb heat, and the refrigeration efficiency of the system not tall. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. Therefore, the present invention proposes an evaporator and a refrigeration system that improve heat absorption efficiency. [0004] The technical scheme that the present invention solves its technical problem adopts is, [0005] The evaporator includes: an outer casing: used for mixing hydrogen and liquid ammonia; a hydro...
