Cooler Effectiveness Calculator

Formula

The formula to calculate the Cooler Effectiveness (e) is:

\[ e = \frac{T_{h_{in}} - T_{c_{out}}}{T_{h_{in}} - T_{c_{in}}} \]

Where:

\( e \) is the Cooler Effectiveness
\( T_{h_{in}} \) is the Temperature of hot air in (°C)
\( T_{c_{out}} \) is the Temperature of cold air out (°C)
\( T_{c_{in}} \) is the Temperature of cold air in (°C)

What is Cooler Effectiveness?

Cooler effectiveness is a measure of how well a cooling system can reduce the temperature of hot air. It is defined as the ratio of the temperature drop of the hot air to the maximum possible temperature drop. A higher effectiveness indicates a more efficient cooling system. This metric is crucial in various applications, including HVAC systems, automotive cooling systems, and industrial processes, where maintaining optimal temperatures is essential for performance and safety.

Example Calculation

Let's assume the following values:

Temperature of hot air in (T_{h_in}) = 100 °C
Temperature of cold air out (T_{c_out}) = 30 °C
Temperature of cold air in (T_{c_in}) = 20 °C

Using the formula to calculate the Cooler Effectiveness:

\[ e = \frac{100 - 30}{100 - 20} = \frac{70}{80} = 0.875 \]

The Cooler Effectiveness is 0.875.
