Air cooler vs Air conditioner

Air conditioner Vs Air coolers Definition: Air Conditioner works on refrigeration principle and  works by using a common physical law – when a liquid turns into a gas, cooling occurs. A fan pulls warm air into the unit which then passes over refrigerant filled coils. The refrigerant absorbs the heat as it changes from a liquid to a gas. Then the resulting cold air is distributed into a room. Then the compressor puts the gas under pressure, which turns it into [...]

Evaporative Air Cooler

An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by exploiting water’s large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration.
