Building managers experience nasty headaches when they balance cost against cooling inside a warehouse. They take one look at the sizable floor space and can’t help calculating the amount of cooling energy required to offset the heat load. It can be done, obviously, but can this goal be achieved without incurring a ballooning energy bill? With cost in mind, cheaper warehouse cooling methods can trust in evaporative coolers.

Solving The Warehouse Cooling Conundrum

Not only do we need a technology that cools large spaces, we also need that engineering solution to accomplish this feat while on a budget. The building manager we just made up doesn’t want any of the stockpiled products to warp or spoil because of the stifling heat, nor does he want any of his workers to feel the effects of heat stroke. A cost-effective solution involves employing one or more evaporative coolers. Built as the original economical cooling appliance, water is the core ingredient here, not a skyrocketing quantity of electrical energy.

Reciprocating Cooling Effects

Contemporary technological cooling systems are counterintuitive. Windows and doors are closed, vents are sealed, and there’s a moment of sweaty claustrophobia to deal with before the equipment takes on the load. In that same warehouse cooling example, evaporative coolers operate at their inexpensive peak while the doors, windows, and loading access points are open. And, should the open air synergy of the operational cycle draw more cooling power, then the effect will only be felt as an empty water reservoir, not an energy-exorbitant rise in electricity costs. A little manual labour soon fills up that “empty tank.”

Dismissing Groundless Cooling Myths

There was a time, not so long ago, that so-called “swamp coolers” used a water tank and a fan to weakly remove heat from the home. Modern evaporative coolers have little in common with such rickety appliances. Modern warehouse evaporative appliances are fixed in massive cooling towers. Man-sized variants are pushed on rugged wheels around warehouse floors so that specific zones can be chilled for the day. They stop distribution centres, product repositories, and large storerooms from becoming unmanageable saunas, thus leaving the interior comfortable for humans, machines, and merchandise.

Curiously, this is an instance where size works in our favour. That heat rises towards the ceiling, where huge, slow-moving fan blades can work in tandem with the portable evaporative coolers on the floor. The result of this concerted cooling solution is a water-based heat rectification system that operates inexpensively. But the negative connotations that come with the word “cheap” are similarly evaporated, for there’s nothing shabby about warehouse-based, water-based, cooling technology.
