Why is adiabatic cooling important

The ability to minimize induction loss, offer high efficiency and generate low noise are the most prominent advantages that spring to mind when it comes to EC fans. In most practical applications, overall energy efficiency is an important factor when it comes to condensers for refrigeration systems and dry coolers for generators and process systems.

When selecting a heat exchanger, therefore, choosing EC fans can help realize the energy-saving objectives of such systems. EC fans, having adopted permanent magnets and other technology features, increase motor efficiency when compared to AC motors.

But apart from those advantages, having a modern controller with specific built-in features will help optimize the full energy-saving potential of EC fans. Look for features such as individual fan operation, the ability to inverse fan direction for cleaning, redundant communication and information-collection capabilities.

Case in Point. A brief case study can help illustrate the benefits possible from using EC fans. In , a gas power generation company wanted to retrofit two radiators of its gen set. This retrofit was brought about due to noticeable year-on-year decreases in the heating dissipation capabilities of the old radiators HT-jacket water, LT-aftercooler water. The old radiators were fitted with AC fans, and even at full load, they no longer could deliver the required capacity.

The company decided to replace the inefficient radiators and selected a product containing two efficient radiators using EC fans and a smart controller. The review showed that the new radiators offered improved performance. The main thermodynamic conditions had remained the same e. To have a clearer view of how the new radiators performed, two electric meters were installed on both the new and old radiators.

Based on two years of data, the analysis shows that the new radiators provide power consumption savings of 74 percent table 2. With adiabatic cooling, the water and motor controllers work together to achieve a process control solution. The water-management controller is equipped with humidity and temperature sensors along with a modulating valve, drain valve and metering device. It reads the fan speed along with the humidity and temperature to determine how much water to distribute to the pad, thereby only using what the ambient air will absorb.

During operation, the controls meter the water evaporated from the pads to reduce overall water consumption. They also regulate the fan speed of the EC fans to reduce overall energy consumption.

Adiabatic cooling causes rapid gas expansion. So, adiabatic cooling we define as heath reduction because of the change of air pressure during volume expansion. Adiabatic cooling is utilized in evaporative coolers. An evaporative cooler is essentially an enormous fan that draws warm air through water-soaked cushions. As the water in the cushions vanishes, the air is chilled and pushed out to the room. The temperature can be constrained by changing the wind stream of the cooler.

In nature, adiabatic cooling is frequently connected with rising. As seen with cloud developments, an air mass that is warmed grows and turns out to be less thick. Back Our solutions.

As you pump vigorously, compressing the air, the metal bicycle pump gets warm. Conversely, when a gas expands, its temperature drops by the same principle.

Physicists use the term adiabatic process to refer to a heating or cooling process that occurs solely as a result of pressure change, with no heat flowing into or away from a volume of air. How does the adiabatic principle relate to the uplift of air and to precipitation? The missing link is simply that atmospheric pressure decreases as altitude increases.

As a parcel of air is uplifted, atmospheric pressure on the parcel becomes lower, and the air expands and cools, as shown in Figure 4. As a parcel of air descends, atmospheric pressure becomes higher, and the air is compressed and warmed. We describe this behavior in the atmosphere using the dry adiabatic lapse rate, as shown in the lower portion of Figure 4. It applies to a rising air parcel that has not yet been cooled to saturation.

This is the dry rate because no condensation occurs during this process. There is an important difference to note between the dry adiabatic lapse rate and the environmental temperature lapse rate.
