(1)设置了间接蒸发冷却盘管预冷段和直接蒸发冷却段,结构紧凑,布局合理。室外空气(二次空气)首先对间接蒸发冷却盘管中循环水进行预冷,循环水同时对另一股室外空气(中间空气)进行冷却,而这股中间空气经过直接蒸发冷却段时与水进行热湿交换,降低了循环水的温度,最后室外空气(一次空气)首先被间接蒸发冷却盘管中温度最低的部分间接冷却,然后再经过直接蒸发冷却段进一步冷却,实现送风温度低于室外空气湿球温度。 (1) The indirect evaporative cooling coil pre-cooling section and the direct evaporative cooling section are set up, with compact structure and reasonable layout. The outdoor air (secondary air) first pre-cools the circulating water in the indirect evaporative cooling coil, and the circulating water cools another outdoor air (intermediate air) at the same time, and this intermediate air is mixed with water when passing through the direct evaporative cooling section. The heat and moisture exchange reduces the temperature of the circulating water. Finally, the outdoor air (primary air) is first indirectly cooled by the lowest temperature part of the indirect evaporative cooling coil, and then further cooled by the direct evaporative cooling section, so that the supply air temperature is lower than The wet bulb temperature of the outside air.
(2)该间接-直接蒸发冷却空调机组中的间接蒸发冷却盘管预冷段实现了循环水的冷量回收,提高了换热效率。 (2) The pre-cooling section of the indirect evaporative cooling coil in the indirect-direct evaporative cooling air-conditioning unit realizes the recovery of the cooling capacity of the circulating water and improves the heat exchange efficiency.
(3)采用间接蒸发冷却盘管,室外空气通过管壁与管内水进行热交换,属于闭式水系统,克服了西北地区风沙、灰尘大的特点,循环水不易受污染,并且在间接蒸发冷却盘管进水口设置水过滤器,减少了直接蒸发冷却段提供给的冷水对盘管的不利影响。 (3) The indirect evaporative cooling coil is adopted, and the outdoor air exchanges heat with the water in the pipe through the pipe wall. A water filter is installed at the water inlet of the coil, which reduces the adverse effect of the cold water provided by the direct evaporative cooling section on the coil.
(4)一次空气风机(送风风机)送出的空气温度低,因此所需送风量小,节省了风机的能效,同时也节省了机组占用空间。 (4) The air temperature sent by the primary air fan (supply fan) is low, so the required air supply volume is small, which saves the energy efficiency of the fan and also saves the space occupied by the unit.
