Condenser Sizing Calculator

Input Parameters

Imperial (°F, BTU, ft)SI (°C, kW, m)

Heat Rejection (BTU/hr)

Refrigerant Type

Condenser Temperature (°F)

Ambient Temperature (°F)

Condenser Area sq ft

Approach Temperature °F

Subcooling °F

Formula:

\Delta T_{approach} = T_{cond} - T_{ambient}

Calculation:

\Delta T_{approach} = 120.0 - 95.0

Result:

25.0 \text{ °F}

Formula:

A = \frac{Q_{reject}}{U \times \Delta T_{approach}}

Calculation:

A = \frac{45000}{200 \times 25.0}

Result:

9.0 \text{ sq ft}
