A set is how many times you are going to lift and then take a break. So if you lift the weight five times, take a break, and lift again you will have done two sets. The five times would be your reps. My coaches like to write the workout like so: Squat 3x2, Bench 2x5, and so on.
Evaporative coolers use both electricity and water. How much water is used depends on the humidity of the day and the fan speed that the unit is set to operate on. A portable unit might use up to 4 litres per hour while a central system could use as much as 25 litres per hour. Ducted evaporative coolers must refresh their water supply otherwise it can become too salty, and a range of water management systems are used by different brands/models.
Evaporative Coolers, sometimes called swamp coolers, is another way to cool air in warm climates with low humidity. | Photo courtesy of Public Domain Photos. In low-humidity areas, evaporating water into the air provides a natural and energy-efficient means of cooling.Evaporative coolers, also called swamp coolers, rely on this principle, cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it.hen operating an evaporative cooler, windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. Unlike central air conditioning systems that recirculate the same air, evaporative coolers provide a steady stream of fresh air into the house.
