How does the hvac running cost calculator work?
Operating energy and cost from entered rates. No live electricity tariffs or universal seasonal efficiency values are assumed. Use measured consumption when possible. Do not enter BTU/h cooling capacity as if it were electrical watts.
Which measurements do you need for hvac running cost?
Use measured consumption when possible. Do not enter BTU/h cooling capacity as if it were electrical watts. Measure the actual installed geometry or quoted quantity rather than substituting a nominal product size.
Which formula calculates hvac running cost?
Electrical kWh = input kW × hours/day × operating fraction × days; input from thermal output = output / COP.
What does a hvac running cost worked example show?
A 2 kW electrical input operating six hours per day at 50% duty for 30 days consumes 180 kWh. At 0.20 per kWh, the cost is 36.
Which units apply to hvac running cost?
Use the labeled units in the input reference below. The Imperial / Metric selection converts fields with dynamic unit labels. Fixed-unit fields retain the units printed in their labels.
Leave optional inputs blank when unavailable. Required fields and paired data are checked before a result is displayed.
| Input | Units | When used |
|---|---|---|
| Measured electrical input (kW) | as labeled | method:input |
| Delivered thermal output (kW) | as labeled | method:cop |
| Verified COP | as labeled | method:cop |
| Scheduled hours per day | as labeled | all modes |
| Average operating fraction (%) | as labeled | all modes |
| Days in period | as labeled | all modes |
| Electricity price per kWh | as labeled | all modes |
Which assumptions change the hvac running cost result?
Operating energy and cost from entered rates. No live electricity tariffs or universal seasonal efficiency values are assumed. Use measured consumption when possible. Do not enter BTU/h cooling capacity as if it were electrical watts.
How should you check the hvac running cost estimate?
Use measured consumption when possible. Do not enter BTU/h cooling capacity as if it were electrical watts. Keep measured values separate from any extra allowance or quoted price. Check the resulting unit and rounding before ordering or using the result.
How can you compare hvac running cost scenarios?
Calculate one baseline and add it to comparison. Change one measured input or verified product value and calculate again. Comparison keeps the itemized inputs and results so the changed assumption remains visible.
How can you save or share the hvac running cost result?
After calculation, copy or share the result, download the worksheet or print the inputs and result. Embed and citation controls are in the header. Clear changes removes the current worksheet, and a browser refresh opens blank numeric inputs.
Which related tools help with hvac running cost?
Use Wet Bulb Calculator, Cfm Calculator, Duct Calculator for related project quantities. Each tool has its own scope; avoid transferring a result without checking its unit and assumptions.
