Description
技术领域technical field
本实用新型属于空调制冷设备技术领域，具体涉及一种基于土建结构的闭式蒸发冷却冷水机组。The utility model belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a closed evaporative cooling water chiller based on a civil structure.
背景技术Background technique
随着全球能源危机的出现及环境的日益恶化，人们开始将注意力转移到了各种清洁可再生能源的利用。干空气能是一种清洁可再生能源，在我国的西北地区就有着非常丰富的干空气能，基于干空气能的特点，将其与本身具有环保节能优势的蒸发冷却技术相结合，更加适合如今节能及环保的大趋势。With the emergence of the global energy crisis and the deteriorating environment, people began to turn their attention to the utilization of various clean and renewable energy sources. Dry air energy is a kind of clean and renewable energy. In the northwest of my country, there is a very rich dry air energy. Based on the characteristics of dry air energy, combining it with evaporative cooling technology, which has the advantages of environmental protection and energy saving, is more suitable for today's The general trend of energy saving and environmental protection.
然而在实际应用中，蒸发冷却技术自身也存在许多的缺点，如：当利用蒸发冷却技术处理的冷风和冷水量比较大时，就使得机组的体积偏大，增大了设备的制作成本，同时增加了设备的占地面积，致使一些需要冷风或冷水量比较大的地方放弃采用蒸发冷却技术，这无疑是一个很大的遗憾。若是能利用土建结构作为机组的一部分，则可以降低机组的制作成本，减少投资。However, in practical applications, the evaporative cooling technology itself also has many disadvantages, such as: when the amount of cold air and cold water processed by the evaporative cooling technology is relatively large, the volume of the unit is too large, which increases the production cost of the equipment, and at the same time It is undoubtedly a great pity that some places that need cold air or a relatively large amount of cold water will give up the use of evaporative cooling technology due to the increased floor space of the equipment. If the civil structure can be used as a part of the unit, the production cost and investment of the unit can be reduced.
立管式间接蒸发冷却器能有效的节省占地面积，进入立管式间接蒸发冷却器内的空气分为两部分：一次风走换热管外，二次风走换热管内，通过二次空气与水的换热来带走一次空气的热量，在立式换热管的上部需要设置一个风机将换热管内二次空气排出。目前立管式间接蒸发冷却器内采用的换热管长度相等，二次空气需要经过一次转弯才能进入换热管内，对二次风产生一定阻力，造成风机的风压加大，从而提高风机的制作投入，并且使不同立管内二次风量不均匀。若是能采取措施减小二次风阻力，则可以降低风机风压，减小风机成本，使立管内风量均匀，提高换热效率。The vertical tube indirect evaporative cooler can effectively save the floor area. The air entering the vertical tube indirect evaporative cooler is divided into two parts: the primary air goes outside the heat exchange tube, the secondary air goes inside the heat exchange tube, and the air passes through the secondary air. The heat exchange between air and water takes away the heat of the primary air, and a fan needs to be installed on the upper part of the vertical heat exchange tube to discharge the secondary air in the heat exchange tube. At present, the length of the heat exchange tubes used in the vertical tube indirect evaporative cooler is equal, and the secondary air needs to go through a turn to enter the heat exchange tubes, which creates a certain resistance to the secondary air, causing the wind pressure of the fan to increase, thereby improving the fan's efficiency. Production input, and make the secondary air volume in different risers uneven. If measures can be taken to reduce the secondary wind resistance, the wind pressure of the fan can be reduced, the cost of the fan can be reduced, the air volume in the standpipe can be made uniform, and the heat exchange efficiency can be improved.
