Sensible Cooling Load Heat Gain through Structure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sensible Cooling Load = Overall Heat Transfer Coefficient*Surface Area*Cooling Load Temperature Difference
Q_{per hour} = U_overall*SA*CLTD
This formula uses 4 Variables

Variables Used

Sensible Cooling Load - (Measured in Watt) - Sensible Cooling Load is the heat added or removed from conditioned space by means of roof, ceiling, floor or windows.
Overall Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - The Overall Heat Transfer Coefficient is a measure of the overall ability of a series of conductive and convective barriers to transfer heat.
Surface Area - (Measured in Square Meter) - The Surface Area of a three-dimensional shape is the sum of all of the surface areas of each of the sides.
Cooling Load Temperature Difference - (Measured in Kelvin) - Cooling Load Temperature Difference is an equivalent temperature difference used for calculating the instantaneous external cooling load across a wall or roof.

STEP 1: Convert Input(s) to Base Unit

Overall Heat Transfer Coefficient: 0.25 Watt per Square Meter per Kelvin --> 0.25 Watt per Square Meter per Kelvin No Conversion Required
Surface Area: 18 Square Meter --> 18 Square Meter No Conversion Required
Cooling Load Temperature Difference: 29 Fahrenheit --> 271.483327150345 Kelvin (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_{per hour} = U_overall*SA*CLTD --> 0.25*18*271.483327150345

Evaluating ... ...

Q_{per hour} = 1221.67497217655

STEP 3: Convert Result to Output's Unit

1221.67497217655 Watt -->4171.31872712307 Btu (th) per Hour (Check conversion here)

FINAL ANSWER

4171.31872712307 ≈ 4171.319 Btu (th) per Hour <-- Sensible Cooling Load

(Calculation completed in 00.004 seconds)

What is the difference between sensible heat gain and latent heat gain?

Latent and sensible heat are types of energy released or absorbed in the atmosphere. Latent heat is related to changes in phase between liquids, gases, and solids. Sensible heat is related to changes in temperature of a gas or object with no change in phase.
