The general way of working is that the engine and propeller pull the hot outside air into the cooler compartment, and in the meantime, the water that is poured between the bags causes the heat of the air that passes through this path to evaporate and the incoming air Cool to the cooler compartment. simply! So, in fact, it can be said that in water coolers, the pushal plays one of the main cooling roles. Pushals are short and long strings that are made from wood by pusher making machines. The permeability structure of wooden poshal and its fibrous structure make the power of poshals to absorb water very high. This increases the efficiency of water coolers and their optimal performance.
Good push feature
The best poshals are generally made of sapidar, dark willow or fir wood. The wood of these trees is able to absorb large amounts of water due to their permeable structure. For this reason, these woods are suitable for making poshal and they are often used.
Water Cooler Types
There are strings of products such as wood that are placed in networks of different materials and cool the air inside the cooler through the water that is poured on them. Pushals are usually considered as one of the main components of the cooler and without them, capital operation is not possible. However, using the cover type will have significant effects on the amount of cold produced by the coolers. Types of covers for water coolers in Iran are divided into three groups: cellulose covers and wooden covers.
