An air cooler lowers the temperature of the air by injecting moisture into it. The air cooler draws in dry air, moistens it with water vapour, and then circulates cooled air around the space. Traditional refrigeration systems are more expensive and inefficient than this method of cooling.
The most energy-efficient cooling technique is air conditioning. The cost of running an air cooler is a tenth of the cost of running a typical air conditioner. A 2.2-ton split air conditioner can use up to 2200 watts per hour in operation. A Sky air cooler uses nearly as much energy as a traditional ceiling fan. Sky air conditioners use between 105 and 255 watts per hour of energy. Although a ceiling fan and an air cooler use the same amount of electricity, the cooling effect is vastly different. Air coolers can cool the air, cover a bigger area, and operate quietly.
Honeycomb and Aspen cooling pads are used in Sky air coolers. Honeycomb pads feature a lattice structure that is similar to that of a honeycomb. Due to the greater surface area for transferring humidity in passing air, this medium delivers a superior cooling effect. Shredded aspen wood fibres are kept together in a pad structure to create aspen cooling pads. Aspen is a completely natural substance with a cooling effectiveness of 75%. Both Aspen and Honeycomb cooling pads are made entirely of natural materials and are extremely cost-effective.
