The adiabatic cooler contributes to energy savings
Adiabatic cooling can be described as the most energy-efficient air-conditioning system on the market.
In fact, the natural process of water evaporation provides the majority of the cooler’s cooling capacity. Energy consumption for ventilation and water circulation accounts for just 5% of the cooling capacity provided. And the higher the temperature, the greater the energy efficiency. This is because, at higher temperatures, the evaporation process accelerates and, consequently, heat extraction from the air increases. The cooler’s cooling capacity increases, while its operating energy consumption remains unchanged.
What’s more, buildings with little or no insulation don’t require significant additional energy consumption , since the cooling capacity of the adiabatic system depends 95% on water evaporation.
The energy required by the electric motors driving the cooler’s water and air cycles requires very little power, both at start-up and during operation. Energy losses due to mechanical friction in ventilation and water circulation account for just 5% of energy consumption, thanks to the simplicity of the hardware configuration.
Of course, power consumption depends on the speed of ventilation and water circulation. It can vary between 1 and 3kWh, depending on the model, to cool a 250m² surface. All in all, an adiabatic cooler is a source of energy savings for air conditioning in hot periods for any industrial plant.
Adiabatic cooling features low water consumption
The industrial sector consumes an average of 500 liters per day per worker. An adiabatic cooler evaporates 120 liters per day for a 250m² room. If this room contains 12 workstations, this amounts to 2% of average daily consumption.
The low water consumption of an adiabatic cooler does not conflict with the restrictions on use announced for the summer period, linked to global warming.
What’s more, the water consumed in the form of water vapour is not subject to any industrial pollution; it returns to the atmosphere, continuing its natural cycle. Similarly, drained water can be discharged untreated into the industrial site’s wastewater system.
Adiabatic cooling has a low ecological footprint
We’ve noted that the adiabatic cooler operates with very low energy and water consumption. Its carbon footprint is moderate.
The adiabatic cooler uses none of the refrigerants that contribute to air pollution and the destruction of the ozone layer. Its only refrigerant is water vapor. So an adiabatic cooler doesn’t contribute to the greenhouse effect linked to anthropogenic refrigerant emissions. Since water vapour only contributes to the global native greenhouse effect linked to the natural water cycle. What’s more, an adiabatic cooler emits an infinitesimal quantity of water vapour compared with that emitted by industrial activities.
Finally, the simple material configuration of an adiabatic cooler means that it has a high level of recyclability at the end of its life. The propylene in the casing can be recycled into acrylic acid, which is used to manufacture polymers such as polystyrene and PVC. Similarly, thecasing’s aluminum is highly recyclable. The fan, pump, probes and other parts are considered electrical and electronic waste, and are subject to a collection and treatment system governed by the European WEEE directive. The evaporative panel can be composted at a waste disposal center.
Throughout its life cycle, the adiabatic cooler generates a low environmental impact. The purchase of an adiabatic cooler is part of a company’s sustainable development policy as an action against global warming.
