Description

智能氨气防漏型果蔬冷库制冷***Intelligent ammonia leak-proof fruit and vegetable cold storage refrigeration system

技术领域 technical field

本实用新型涉及一种果蔬冷库制冷***，尤其是一种智能氨气防漏型果蔬冷库制冷***。  The utility model relates to a refrigeration system for a fruit and vegetable cold storage, in particular to an intelligent ammonia gas leakage-proof refrigeration system for a fruit and vegetable cold storage. the

背景技术 Background technique

蒸发器是制冷剂在其中蒸发的热交换器。在制冷***中，蒸发器是产冷设备，低温的制冷剂通过蒸发器，与外界的空气进行热交换，气化吸热，达到制冷的效果。冷库用的蒸发器属于间壁式热交换器，蒸发器的热量通过管壁式板壁传给制冷剂，制冷剂在低温下气化，把热量从蒸发器带走，蒸发器再和被冷却介质(一般是空气)发生热交换，从而达到制冷的目的。  An evaporator is a heat exchanger in which the refrigerant evaporates. In the refrigeration system, the evaporator is a cooling device. The low-temperature refrigerant passes through the evaporator, exchanges heat with the outside air, and vaporizes to absorb heat to achieve the cooling effect. The evaporator used in the cold storage belongs to the partition wall heat exchanger. The heat of the evaporator is transferred to the refrigerant through the tube wall type wall. The refrigerant gasifies at a low temperature and takes the heat away from the evaporator. Generally, air) undergoes heat exchange, so as to achieve the purpose of refrigeration. the

由于液氨被作为制冷剂广泛应用于冷库制冷***中，氨气在冷库蒸发器内的防漏一直是一个被重点关注的话题，由于液氨的气化压力很大，如果蒸发器产生气孔或裂缝，氨气会迅速泄露，冷库内储藏的生鲜果蔬长时间暴露在氨气环境中，会很快发生腐烂变质；并且由于冷库是密闭区域，氨气泄露后，冷库管理人员不能立刻发现，因此一些冷库由于氨气泄露造成的损失很大。  Since liquid ammonia is widely used as a refrigerant in cold storage refrigeration systems, the leakage prevention of ammonia gas in the cold storage evaporator has always been a topic of great concern. Due to the high vaporization pressure of liquid ammonia, if the evaporator produces pores or If there are cracks, ammonia gas will leak quickly, and the fresh fruits and vegetables stored in the cold storage will rot and deteriorate soon after being exposed to the ammonia environment for a long time; and because the cold storage is a closed area, after the ammonia gas leaks, the cold storage management personnel cannot find it immediately. Therefore, some cold storages have suffered great losses due to ammonia leakage. the
