1. Principles and advantages of air coolers

We should introduce the corresponding principles and advantages of the differences between cold air fans and air conditioning fans. A cold air fan, in simple terms, is a device that can bring cold air, but as a commodity, it mainly refers to a cooling machine equipment used in industry. Unlike central air conditioning, which uses refrigeration compressors for cooling, it uses a simpler and more violent method of water evaporation for cooling. Therefore, it cannot be compared to air conditioning in terms of cooling capacity, but it is particularly energy-efficient. For example, high-power cooling fans used in processing plants only consume one degree of electricity per hour, but can reduce a room of over 100 square meters by more than five degrees.

2. Principles and advantages of air conditioning fans

Because in principle, household air conditioning fans are very similar to industrial grade air coolers, both of which obtain wind speed through fans, allowing water to evaporate faster and achieve cooling effects. However, because the output power of these household appliances is particularly small, their cooling ability is limited. It is already good to reduce the indoor temperature by two to three degrees. However, due to its small size, its power consumption and output power are similar to those of a regular electric fan, and there is no need to consider water and electricity costs like central air conditioning.
