When we use air coolers, sometimes we encounter the phenomenon of poor refrigeration effect, so what are the reasons for this phenomenon?
In response, air cooler manufacturers say hot air recirculation can be a problem at any time of the year. In the hot summer months, it can greatly reduce the capacity of the air cooler. The main reasons for the problem are discussed here:
1. Avoid installing the air cooler on buildings and structures near the downwind side. The hot air comes out of the air cooler and is carried by the wind. After hitting the obstacle, some of the hot air circulates back into the inlet. This problem can be mitigated by using a blast fan with a sufficiently high exhaust duct. However, the best way is to install the air cooler away from these obstacles.
2, air cooler with blast fan, always easy to recirculate air. If the air cooler is installed too close to the ground, it will produce a high air approach speed, and hot air recirculation may become very severe. The blast air cooler is installed at a relatively high place on the ground, preferably above the pipe gallery. If the air cooler is close to other structures, an exhaust pipe can be installed in the upper part of the bundle to minimize the amount of hot air recirculation.
3, closely placed into the exhaust cooler and the dominant wind direction to maintain consistent installation, easy to produce hot air recirculation. The long axis of the air cooler should be perpendicular to the dominant summer wind direction when it is installed. Multiple air coolers close together, such as the combination of induced air and blast air, can also cause air recirculation. Avoid installing the air cooler on the downwind side of the hot equipment. At the same time, it should also be avoided that the air cooler has different elevations when it is installed closely. If the air cooler needs to be installed on the downwind side of the heating equipment, the air inlet towards the heating equipment should be blocked, so that the problem can be alleviated.
