Description
技术领域technical field
本实用新型涉及空调制冷技术领域，特别是一种用于煤矿救生舱的空气冷却***。The utility model relates to the technical field of air conditioning and refrigeration, in particular to an air cooling system used for a coal mine rescue cabin.
背景技术Background technique
煤矿井下发生灾害性事故时，煤矿救生舱的空气冷却***能够为躲进救生舱中的矿工提供必需的生存温度，使舱室内环境环境温度维持在32℃以下，基本满足人类生存要求。目前，煤矿救生舱空气冷却装置可分为两类：一是普通分体式空调，空调主机置于救生舱内部，而制冷压缩机必须外置。因此，在瓦斯***、透水事故频发的煤矿中，救生舱空调制冷压缩机等有源部件的防爆是不得不面对的问题。二是蓄冷式防爆空调，该***包括舱外防爆制冷机组和舱内空气调节装置。这两类装置在密闭空间中要保持让人舒适的温度，需要有足够的电力维持空调的运行，而发生事故时外部电力切断，只能依靠蓄电池供电。在灾害状态下要维持较长时间的制冷，就需要储备大量的电能，因此会导致舱室内蓄电池体积过大。When a catastrophic accident occurs underground in a coal mine, the air cooling system of the coal mine rescue cabin can provide the necessary survival temperature for the miners hiding in the rescue cabin, and keep the ambient temperature in the cabin below 32°C, which basically meets the survival requirements of human beings. At present, the air cooling devices for coal mine rescue cabins can be divided into two categories: one is the common split air conditioner, the main unit of the air conditioner is placed inside the rescue cabin, and the refrigeration compressor must be external. Therefore, in coal mines where gas explosions and water seepage accidents occur frequently, the explosion protection of active components such as air-conditioning and refrigeration compressors in rescue cabins is a problem that has to be faced. The second is the cold storage explosion-proof air conditioner, which includes an explosion-proof refrigeration unit outside the cabin and an air conditioning device inside the cabin. To maintain a comfortable temperature for these two types of devices in a confined space, there needs to be enough power to maintain the operation of the air conditioner. In the event of an accident, the external power is cut off and they can only rely on battery power. To maintain refrigeration for a long time in a disaster state, a large amount of electric energy needs to be stored, which will cause the battery in the cabin to be too large.

本实用新型所述的虹吸式液态二氧化碳储液瓶出口至热力膨胀阀出口之间的管路外包绝热层。The pipeline between the outlet of the siphon type liquid carbon dioxide storage bottle and the outlet of the thermal expansion valve described in the utility model is covered with a thermal insulation layer.
本实用新型所述的喷射式制冷***是一种将制冷剂直接喷入大气的、无冷凝器的开放式制冷***。The spray refrigeration system described in the utility model is an open refrigeration system without a condenser, which sprays refrigerant directly into the atmosphere.
本实用新型所述的喷射式制冷***中的液态二氧化碳制冷剂也可以是其它能在室温条件下释放潜热并产生高压气体，而后通过喷嘴可产生高速气流的制冷剂。The liquid carbon dioxide refrigerant in the spray refrigeration system described in the present invention can also be other refrigerants that can release latent heat and generate high-pressure gas at room temperature, and then generate high-speed airflow through the nozzle.

1、由于本实用新型中用于煤矿救生舱的空气冷却***可在外部电源切断和内部无蓄电池的情况下，在救生舱室内独立工作，为救生舱内提供必要的冷量。1.
