Greenhouse Evaporative Cooling

If ventilation and shading are not sufficient, greenhouse temperatures can be controlled by means of evaporative cooling, also referred to as swamp cooling.

When water evaporates in the air, energy is needed. This energy comes from heat, which is dissipated from the hot air. The more water can evaporate in the air, the more heat is dissipated and thus the more the greenhouse is cooled. The initial temperature and the initial relative humidity of the air determine how much water can be evaporated and thus what the cooling capacity is and how much the greenhouse temperature can drop.

Advantages of Enerdes® Evaporative Cooling Systems

Two types of greenhouse cooling systems are available of which the working principles are based on evaporative cooling: cooling pads (the fan and pad cooling system) or adiabatic cooling with a fogging system or misting system. Read more about the advantages below:

Less costs to operate

The combination of lower energy consumption, reduced initial investment, lower maintenance costs, water efficiency, and environmental benefits contributes to cost savings with evaporative cooling in a greenhouse compared to more complex and energy-intensive cooling systems.

No use of CFC’s or HCFC’s

Evaporative cooling is a natural cooling process that uses water evaporation to reduce air temperature. It doesn’t involve any refrigerants or chemical substances.

Especially effective in dryer climates

Dry climates have low humidity levels, which means the air can absorb more moisture. When water is evaporated into the dry air, it evaporates quickly and effectively, leading to a more substantial cooling effect.
