Calculate Annual Heat Loss (AHL)



Formula

The formula to calculate the Annual Heat Loss (AHL) is:

\[ AHL = \frac{ELR}{dT} \times 24 \times 365 \]

What is Annual Heat Loss?

Annual heat loss refers to the total amount of heat lost from a building or system over the course of a year. It is calculated based on the energy loss rate, the design temperature difference, and the number of hours in a year. Understanding annual heat loss is crucial for designing efficient heating systems and improving energy conservation.

Example

Let's say the energy loss rate (ELR) is 500 BTU/hr, and the design temperature difference (dT) is 50 F. Using the formula:

\[ AHL = \frac{500}{50} \times 24 \times 365 = 87,600 \text{ BTU/F} \]

So, the annual heat loss (AHL) is 87,600 BTU/F.

Heat Loss Calculation

Definition: Heat loss calculation determines the amount of heat lost from a building or space.

Formula: \( Q = U \times A \times \Delta T \)

Example: \( Q = 0.5 \times 100 \times 20 \)

Simple Heat Loss Calculation

Definition: A simplified method to estimate heat loss.

Formula: \( Q = \frac{k \times A \times \Delta T}{d} \)

Example: \( Q = \frac{0.04 \times 50 \times 15}{0.1} \)

Heat Loss Calculation for Residential Buildings

Definition: Calculating heat loss specifically for residential buildings.

Formula: \( Q = \sum (U \times A \times \Delta T) \)

Example: \( Q = (0.3 \times 30 \times 25) + (0.5 \times 20 \times 25) \)
