一、概述J_2-2空调机组安装在新厂房15.3m,是为装箱间采暖通风和防暑降温的空调设备。其设备性能为:风量L=20000M~3风机功率N=11KW配有8排表冷器和4排蒸汽加热器。通风形式为全新风。交付使用后,装箱间的温度无论冬季或夏季都不理想。经实测,室外气温35.5℃、相对湿度64%,而室内温度在通过空调降温处理后仍达到31.2℃,1999年1月实地测量,室外气温8.1℃室内温度在通过空调升温处理后只有16.7℃,效果极不理想。二、改造方案根据计算,系统配置8排表冷器冷冻水流量以达到40吨/小时,而装箱间面积是1900M~2,由
I. Overview J_2-2 air-conditioning unit installed in the new plant is 15.3m, which is the air-conditioning equipment for heating, ventilation and cooling in the box room. Its equipment performance is: air volume L=20000M~3 fan power N=11KW equipped with 8 rows of surface coolers and 4 rows of steam heaters. Ventilation in the form of fresh air. After delivery, the temperature in the container room is not ideal for winter or summer. According to actual measurement, the outdoor temperature is 35.5°C and the relative humidity is 64%, while the indoor temperature still reaches 31.2°C after being cooled by the air conditioner. In January 1999, it was measured on the spot. The outdoor temperature of 8.1°C was only 16.7°C after the air temperature was increased. The effect is extremely unsatisfactory. Second, the transformation program According to the calculation, the system configuration 8 row cooler cooling water flow to reach 40 tons / hour, and the packing room area is 1900M ~ 2, by
