The **Refrigerant Cooling Capacity Calculator** helps calculate the cooling capacity based on refrigerant flow rates and enthalpy changes. It is important in the design and optimization of refrigeration and air-conditioning systems.

### Cooling Capacity Formula:

The cooling capacity is calculated as:

\[
\text{Cooling Capacity} = \dot{m} \times (h*{\text{in}} - h*{\text{out}})
\]

Where:

- \(\dot{m}\) is the mass flow rate of the refrigerant (kg/s),
- \(h_{\text{in}}\) is the inlet enthalpy (kJ/kg),
- \(h_{\text{out}}\) is the outlet enthalpy (kJ/kg).

This formula calculates the cooling effect produced by the refrigerant in kilowatts (kW).

### Example:

For a refrigerant mass flow rate of 0.5 kg/s, an inlet enthalpy of 200 kJ/kg, and an outlet enthalpy of 150 kJ/kg, the cooling capacity would be:

\[ \text{Cooling Capacity} = 0.5 \times (200 - 150) = 25 \text{ kW} \]

This tool is useful for HVAC engineers and system designers in evaluating the performance of cooling systems.
