The large dry-type air cooler is typically designed as a falling-type system. This type of air-cooling fan consists of three main sections: the upper part, the middle section, and the lower part. The lower section serves as a water tray, which collects condensation or frost water from the cooling process and provides structural support for the fan. It also functions as the air inlet. The upper part features an exhaust hood where the fan is mounted. Depending on the required airflow and vertical pressure, either an axial-flow fan or a centrifugal fan can be selected. Axial-flow fans are generally more cost-effective and offer higher air volume, while centrifugal fans provide better pressure control. A shower pipe is installed between the hood and the tube bundle to facilitate water distribution during the cooling process. The middle section contains the air-cooled exhaust pipes, also known as the evaporator tubes. For sleeve-type coolers, the cooling tube bundle is made from seamless steel pipes with a diameter of D25×2.5mm, and the outer cover is typically a 0.5mm galvanized steel sheet or an aluminum plate. Falling-type air coolers are categorized based on their air outlet configuration: top-air blowers, side-air blowers, and upper-side air blowers. In cold storage applications, there are three common types of cooling chillers: KLD-type drop chillers are used in freezing refrigerated rooms, KLL-type chillers are used for cooling refrigeration spaces, and KLJ-type chillers are designed for freezing areas. Each type is specifically tailored to meet different temperature and humidity requirements in various storage environments.
