The formula to calculate the HVAC operating cost is:
\[ C = \frac{P \times H \times C_{\text{rate}} \times D \times M}{1000} \]
where \( C \) is the HVAC operating cost, \( P \) is the power consumption in kilowatts (kW), \( H \) is the number of hours per day, \( C_{\text{rate}} \) is the cost per kilowatt-hour (kWh), \( D \) is the number of days per month, and \( M \) is the number of months per year.
HVAC operating cost refers to the total amount of money spent on running and maintaining a Heating, Ventilation, and Air Conditioning (HVAC) system. This cost includes the energy consumption of the system, regular maintenance, and any necessary repairs or replacements. The operating cost can vary greatly depending on the type and age of the system, specific usage patterns, and the cost of energy in the area.
Let's assume we have the following values:
Step 1: Multiply the power consumption by the number of hours per day, the cost per kWh, the number of days per month, and the number of months per year:
\[ 5 \times 8 \times 0.12 \times 30 \times 12 = 1728 \]
Step 2: Divide by 1000 to convert to kilowatt-hours:
\[ \frac{1728}{1000} = 1.728 \]
Therefore, the HVAC Operating Cost is \( C = \$1.728 \).
