Commercial, Cool n Save, SAVINGS Calculator

 
 Energy Efficiency Rating     EER
This EER can usually be found right on the unit and refers to how many BTU's of cooling are accomplished per watt. These numbers are calculated under ideal conditions w/ brand new machines. So using this number is a very conservative estimate. This number ranges between 8 and 14. Though for older machines a number of 10 would be a conservative choice      
 Air Conditioners Capacity in BTUh     BTUh
British Thermal Units per hour are a measurment used to determine the cooling capacity of the air conditioner. Commercial units range fron 90,000 BTUhto over 1,000,000 BTUh. The most common being a 120,000 BTUh      
 Condensers to be Cooled     Condenser
How many condensers are going to cooled on the building. Our Commercial unit has 2 pumps in it that provide the water pressure for the misters. Each machine can cool up to 4 condensers      
 Estimated Hours of Operation per Day     hours/day
This can range from 2 or 3 hours to over 20 hours per day depending on the site      
 Days of Operation per Month     days/month
For commercial operations this depends on the days of operation a store might be every day of the month while a business might just be on just during business hour during the week.      
 Months of Operation per Year     months/year
Depends on area and climate      
 Cost of Electricity per KWh***     KWh
Kilowatt's per hour. This can be found on your power bill, though is sometimes hard to decifer because there are different rates for peak hours and higher rates above a certain base usage. With current power costs, each KWh is ranging from $ .12 to more then $.19.      
 Expected Energy Savings     EES
We are consistently getting between 20% and 30% savings on the energy used to power the air conditioner      
 Energy Used by the Cool-n-Save  
0.06
   Fixed
The Cool-nSave Commercial employes two very efficient pumps to send the water to our mist nozzles that greatly increase the air conditioner's ability to transfer heat and hense operate much more efficiently. When in operation our pumps consume 60 watts (.06 KWh) per condenser.

* 1.37 pounds of CO2 per KWh & 1,700 kWh. per 42 gallon Barrel.  See links & info below.

** KWh (Kilowatt hour). A KWh is 1000 Watts being used for 1 hour or how much energy it takes to run (20) 50 watt light bulbs for one hour.

*** Costs per KWh - to figure this number it is necessary to take your total varible costs of energy which include taxes and fees on top of the stated cost of electricity. It is also important to factor in the cost per KWh at the time of usage. Rates are normally much higher during peak hours (during the day) and during the summer months. The actual costs of the energy saved can be over $ .30 per KWh.
