Refrigerant Compressor Power Calculator

The Refrigerant Compressor Power Calculator estimates the power needed by a refrigerant compressor based on the mass flow rate of the refrigerant and the specific work required for compression.

Compressor Power Formula:

The power consumption of a compressor is calculated using:

\[ \text{Compressor Power (kW)} = \frac{\dot{m} \times W_{\text{specific}}}{1000} \]

Where:

• \(\dot{m}\) is the mass flow rate of the refrigerant (kg/s),
• \(W_{\text{specific}}\) is the specific work of the compressor (kJ/kg).

Example:

If the mass flow rate is 0.5 kg/s and the specific work is 250 kJ/kg, the compressor power would be:

\[ \text{Compressor Power} = \frac{0.5 \times 250}{1000} = 0.125 \text{ kW} \]

Significance:

Accurate calculation of compressor power is essential for designing efficient refrigeration and air-conditioning systems, helping engineers ensure that the system operates within optimal energy consumption limits.
