The Internal Gains Calculator is a tool designed to estimate the total internal heat gains within an enclosed space, often used in architectural design or energy assessments. This calculator provides insight into the total energy contribution from electrical appliances, considering their power consumption, duration of use, and a correction factor that accounts for various factors influencing internal gains.
Formula of Internal Gains Calculator
The formula used by the Internal Gains Calculator is as follows:
Internal Gains (kWh/year) = Σ(Pe * Hf * ηi)
Where:
- Pe represents the power of each electrical appliance in Watts (W).
- Hf indicates the number of hours per day the appliance is in use (hours).
- ηi stands for the internal gains correction factor.
This calculation allows users to estimate the total internal gains in kilowatt-hours per year based on the specified inputs of power, hours of use, and the correction factor.
General Terms and Conversions
Commonly Searched Terms
Here are some general terms that individuals frequently search for while using the Internal Gains Calculator:
- Power (Watt)
- Hours of Use (per day)
- Internal Gains Correction Factor
These terms provide users with a better understanding of the factors involved in the calculation, aiding in smoother and more informed usage of the calculator.
Example of Internal Gains Calculator
Consider an electrical appliance with a power consumption of 1000 Watts (1 kW) used for 5 hours a day with an internal gains correction factor of 0.8. Using the formula:
Internal Gains = 1000 * 5 * 0.8 = 4000 kWh/year
This example demonstrates how to calculate the estimated annual internal gains for a specific appliance.
