Here is how the Cooling ratio equation looks like.

0.9 = \frac{400 - 310}{400 - 300}

0.9 = \frac{400K - 310K}{400K - 300K}

0.9 = \frac{400 - 310}{400 - 300}

Cooling ratio Solution

Follow our step by step solution on how to calculate Cooling ratio?

FIRST Step Consider the formula

q = \frac{T 2 - T 3}{T 2 - T 1}

Next Step Substitute values of Variables

∴

q = \frac{400K - 310K}{400K - 300K}

Next Step Prepare to Evaluate

∴

q = \frac{400 - 310}{400 - 300}

LAST Step Evaluate

∴

q = 0.9

How to Evaluate Cooling ratio?

Cooling ratio evaluator uses Cooling Ratio = (Suction Temperature at High Pressure Compressor-Discharge Temperature at High Pressure Compressor)/(Suction Temperature at High Pressure Compressor-Suction Temperature at Low Pressure Compressor) to evaluate the Cooling Ratio, Cooling ratio formula is defined as a dimensionless value that expresses the efficiency of a refrigeration system, comparing the temperature differences between the hot and cold sides of the system, providing a measure of the system's ability to transfer heat. Cooling Ratio is denoted by q symbol.

How to evaluate Cooling ratio using this online evaluator? To use this online evaluator for Cooling ratio, enter Suction Temperature at High Pressure Compressor (T₂), Discharge Temperature at High Pressure Compressor (T₃) & Suction Temperature at Low Pressure Compressor (T₁) and hit the calculate button.

FAQs on Cooling ratio

What is the formula to find Cooling ratio?

The formula of Cooling ratio is expressed as Cooling Ratio = (Suction Temperature at High Pressure Compressor-Discharge Temperature at High Pressure Compressor)/(Suction Temperature at High Pressure Compressor-Suction Temperature at Low Pressure Compressor). Here is an example- 0.9 = (400-310)/(400-300).

How to calculate Cooling ratio?

With Suction Temperature at High Pressure Compressor (T₂), Discharge Temperature at High Pressure Compressor (T₃) & Suction Temperature at Low Pressure Compressor (T₁) we can find Cooling ratio using the formula - Cooling Ratio = (Suction Temperature at High Pressure Compressor-Discharge Temperature at High Pressure Compressor)/(Suction Temperature at High Pressure Compressor-Suction Temperature at Low Pressure Compressor).
