How is gas cost calculated?
Take the mileage of the total distance of your trip and divide it by your miles per gallon to get the number of gallons of gas you will need on your trip. Then multiply that figure by the current price of gas, and the result is the estimated cost of gas for your road trip.
How do you calculate refrigerant charge?
No complicated math required, you simply add together the gas in the pipe, the compressor/condenser section, and the evaporator = total charge. As a result, they only capture between 30-40% of the system charge and therefore under report capacity charge.
How do you calculate gas cost per month?
Here’s the formula:
- (total monthly mileage) / (average MPG of your van) = (# of gallons of gas needed)
- (# of gallons of gas needed) x (price of gas) = your estimated gas costs for the month.
- (1,555) / (14.5) = 107 gallons of gas needed for one month.
- (107) x (2.50) = $268 are her estimated gas costs for the month.
How is VRF calculated?
The criteria for a unit to be a VRF is having several indoor air-handling units and one outdoor condenser or compressor. That means that if you have a 10 ton condenser unit with 13 indoor units each 1 ton, then your diversity factor is 130%. That means that you have 30% more capacity in evaporation than condensation.
How do you calculate fuel cost per km?
If you know the price of fuel, then you can simply multiply the price per litre by the result and that gives you your cost per 100km. E.g. if fuel is $2, then 8.98l/100km means that it takes $17.96 of fuel to travel 100km, or around $0.18 per kilometre, not including your other costs like wear and tear.
How much refrigerant is in a Lineet?
If the rating plate subcooling is greater, units should be charged 10 degrees subcooling. For 15 feet of line set and a matched indoor coil, outdoor units are pre-charged at the factory. For line lengths greater than 15 feet, add 0.6 oz. Refrigerant per foot of line length.
What is refrigerant charge?
Refrigerant charging refers to the replenishment of these gases when system repairs or leaks have caused depleted levels. Refrigerant charging may be carried out using bulk refrigerant containers or charging kits which generally only hold enough gas for one charge.
What is EER in VRF?
EER is defined as the ratio of cooling capacity in watts to electrical input in Watts. Any how, EER ( Energy Efficiency Ratio) or performance of an VRF can be evaluated by operating the entire system at full load capacity.
