Cooling load from lighting Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cooling Load from Lighting = 3.4*Lighting Capacity*Ballast Factor*Cooling Load Factor for Lighting
Q_l = 3.4*W*BF*CLF_L
This formula uses 4 Variables

Variables Used

Cooling Load from Lighting - (Measured in Watt) - Cooling load from lighting is cooling load due to heat gain from lighting.
Lighting Capacity - (Measured in Watt) - Lighting capacity is W is the rated capacity of the lights in use.
Ballast Factor - The Ballast Factor is a number, typically between 0.70 and 1.2, that tells you how much light a lamp will emit with that ballast.
Cooling Load Factor for Lighting - Cooling Load Factor for Lighting is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating.

STEP 1: Convert Input(s) to Base Unit

Lighting Capacity: 45 Btu (IT) per Hour --> 13.1881981577502 Watt (Check conversion here)
Ballast Factor: 1.2 --> No Conversion Required
Cooling Load Factor for Lighting: 12 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_l = 3.4*W*BF*CLF_L --> 3.4*13.1881981577502*1.2*12

Evaluating ... ...

Q_l = 645.69418180345

STEP 3: Convert Result to Output's Unit

645.69418180345 Watt -->2203.19999999999 Btu (IT) per Hour (Check conversion here)

FINAL ANSWER

2203.19999999999 ≈ 2203.2 Btu (IT) per Hour <-- Cooling Load from Lighting

(Calculation completed in 00.035 seconds)
