How Evaporation Cooling Works?
When considering water evaporating into air, the wet-bulb temperature, as compared to the air’s dry-bulb temperature, is a measure of the potential for evaporation cooling. The dry and wet bulb temperature can be used to calculate the relative humidity.Evaporation will take place when the humidity is below 100% and the air begins to absorb water. Any given volume of air can hold a certain amount of water vapor and the degree of absorption will depend on the amount it is already holding.The term humidity describes how much water is already in the air; relative to the amount it is capable of holding. Air is saturated when it cannot hold any more water. Imagine it as a sponge, if the sponge held half as much water as it was capable of holding, it would be 50% saturated. In the case of air, we would describe the Relative Humidity as being 50%. Energy is required to change water from liquid to vapor. This energy is obtained in an adiabatic process from the air itself. Air entering an evaporation air cooler gives up heat energy to evaporate water. During this process, the dry bulb temperature of the air passing through the cooler is lowered.

Roof Mounted Ventilation System
Exhaust ventilators feature rugged construction and are highly weather resistant. They can provide a steady exhaust of clean air, and are engineered to help reduce energy costs by circulating air, cooling attics, reducing overall air conditioner strain, and also help prevent heat and moisture buildup. Roof ventilators are designed to help exhaust contaminated air from kitchen range hoods up and away from the roof. Filtered supply ventilators help supply filtered make up air in commercial or institutional buildings. Some models feature a hinged hood to ease access to motor and drives for maintenance. We even have ventilators designed for solar or wind operation to help reduce your energy costs. Ventilators are suitable for use in a variety of industrial and commercial buildings, including warehouses, manufacturing facilities, foundries, and laboratories. Go to Granger when you need roof ventilators, roof vents, roof exhaust fans, and accessories for your ventilation systems.
Natural Turbine Ventilation System
The natural turbine vent spins freely and easily, removing warm air from the building using natural ventilation. It is made of marine grade, light-gauge aluminum to ensure that it won’t rust or seize, even after years of operation. It is designed to spin in the lightest of breezes. Even if it doesn’t seem windy outside the Greenroom will continue to exhaust warm air from the building because that warm air is what is powering it. As the warm air rises through natural convection it flows through the turbine. This airflow causes the rotary vent to spin and in turn draws more air through itself. This self-perpetuating cycle is what makes the Greenroom turbine vent so effective. The aluminum construction places little wind load on the roof. This makes installation easier and prevents the need for expensive support steel. In fact, in instances where a Greenroom is replacing exhaust fans, it can often fit right into the same opening, making installation a breeze.
