HVAC Operating Cost Calculator

Formula

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.

What is HVAC Operating Cost?

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.

Example Calculation

Let's assume we have the following values:

Power Consumption ( $P$ ) = 5 kW
Hours per Day ( $H$ ) = 8 hours
Cost per kWh ( $C_{\text{rate}}$ ) = $0.12
Days per Month ( $D$ ) = 30 days
Months per Year ( $M$ ) = 12 months

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 $C = \$1.728$ .
