Line Set Load Calculator

Formula

The formula to calculate the Line Set Load (Q) is:

\[ Q = \frac{L \cdot k \cdot \Delta T}{t} \]

Where:

\( Q \) is the line set load in watts
\( L \) is the length of the line set in meters
\( k \) is the thermal conductivity of the insulation in W/(m·K)
\( \Delta T \) is the temperature difference in Kelvin
\( t \) is the thickness of the insulation in meters

Definition

Line Set Load: The amount of thermal energy transferred through a line set, which is a pair of copper tubes that carry refrigerant between the outdoor and indoor units of an HVAC system.
Significance: Proper calculation of the line set load is crucial for ensuring the efficiency and performance of the HVAC system.

Example

Let's say the length of the line set (L) is 10 meters, the thermal conductivity of the insulation (k) is 0.04 W/(m·K), the temperature difference (ΔT) is 30 K, and the thickness of the insulation (t) is 0.05 meters. Using the formula:

\[ Q = \frac{10 \cdot 0.04 \cdot 30}{0.05} = 24 \]

So, the line set load (Q) is 24 watts.
