Before purchasing your Walk In freezer or cooler, you might wonder how much it will cost to keep the Freezers and Cooler running efficiently. Operating costs associated with these two types of equipment must be considered.
Figures for Walk-In Freezer and Cooler with Standard Sizes
To estimate the amount, it would cost to run a walk-in freezer or cooler, we’ve used the average national cost – in the range of $0.1071 per Kilowatt – as an indicator. Explore the table below.
Cooler | Average Cost per month | Freezer | Average Cost per month |
6×6 | $70.74 | 6×6 | $244.13 |
6×8 | $70.74 | 6×8 | $244.13 |
8×8 | $126.49 | 8×8 | $244.13 |
8×10 | $119.30 | 8×10 | $372.27 |
8×12 | $119.30 | 8×12 | $372.27 |
10×10 | $151.07 | 10×10 | $372.27 |
10×12 | $151.07 | 10×12 | $435.66 |
The figures were compiled using a 12-month rolling average of $0.1071 Kilowatt hour costs. According to the Energy Information Administration, this is the common expense for commercial electricity in America during November 2014.
Various assumptions were used to form this chart to estimate your running costs.
- The kind of insulation incorporated in the walk-in is taken into account.
- The optimization of the refrigeration system is another factor that affects cost.
- The fridge environment’s inside, and outside temperatures are also considered.
- Another component used was the area in which the refrigerator is located.
- Additionally, the temperature and mass of goods entering a walk-in are considered important to cost estimation.
- How often any door within the refrigeration unit is opened also influences overall prices.
- Also, its historical use will factor in too when calculating operating expenditures incurred over time.
- Lastly, electricity bills will impact the overall spending required for the walk-in fridge usage.
If you’d prefer a more accurate reading of how much your electric rate would be, take note of the following guidelines.
Generally, refrigeration systems are designed to function 80% of the time – that amounts to between 16-18 hours per day. You can use the formula and chart given below to calculate how much running your walk-in will cost.
We have computed an average number of kilowatt hours that played a role in a typical walk-in’s operation. To estimate the monthly cost, choose your preferred walk-in and multiply it by AKWH (Average Kilowatt Hours).
C = Cost for every month on average
Cooler | Avg. KW hours per month (AKWH) | Freezer | Avg. KW hours per month (AKWH) |
6×6 | 660.48 | 6×6 | 2,279.49 |
6×8 | 660.48 | 6×8 | 2,279.49 |
8×8 | 1,181.03 | 8×8 | 2,279.49 |
8×10 | 1,113.86 | 8×10 | 3,475.91 |
8×12 | 1,113.86 | 8×12 | 3,475.91 |
10×10 | 1,410.51 | 10×10 | 3,475.91 |
10×12 | 1,410.51 | 10×12 | 4,067.82 |
For example, let’s take the 8×10 cooler, which demands 1,113.86 AKWH multiplied by the price per each month KWH, which is 11.89 cents here.
1,113.86 (AKWH) * $11.89 = $132.44 monthly expenditure overall.
Calculating the Cost of a Custom-Sized Walk in freezer or cooler:
Are you looking for an estimate for a walk-in that is not a standard size? If so, the following formula may be helpful. To get the BTU (British Thermal Unit) figure that you need, contact Unity Cooling Systems at (281) 818-5959 or take advantage of their refrigeration Sizing Program and find out the best size for your walk-in. However, if you have an agent or dealer connected to Unity Cooling Systems, they will need the amperage and voltage of your refrigeration system – this corresponds with your BTU requirement. Once you have those two numbers in hand, use this equation to compute your average monthly electricity cost accurately. Don’t forget to have the amperage and voltage of the condensing unit and that of the evaporator coil available too!
The equation for determining the cost of electricity for a Walk In cooler each month is
(((TW *16)/1000) * 30.42) * C
While the energy cost regarding freezers is calculated as: (((TW)*18)/1000) *30.42) * C.
16 and 18 stand, respectively for the time taken to design and run a Walk In freezer and cooler daily, while 30.42 symbolizes the general number of days in a calendar month.
The variables A and V represent Amperage and Total Voltage referencing the refrigeration unit, respectively, and C refers to the rate of Kilowatt paid every dollar based on current electricity bills available.
Last but not least, TW is comprised of (A*V) for both condensing units as well as evaporator coils.
The total Watts (TW) for the refrigeration system can be calculated by taking an amperage (A) multiplied by the voltage (V) of both the condensing unit and evaporator coil. This determines how many Watts are consumed, multiplied by the usual amount of hours the equipment operates each day; coolers typically run 16 hours while freezers go on for 18 hours. After this, to figure out how many Kilowatts are used daily, multiply the number by 30.42 (the average number of days in a month). Ultimately, divide the monthly kilowatts requirement by the cost of electricity in your area to determine your monthly expenditure. Thus, you can estimate what it costs to keep your walk-in running daily.
Example: How much electricity does a Walk In cooler use (8×10)?
A cooler 8×10 condensing unit has 9.5 Amperes and 230 Volts. The evaporator coil also comes with 9 A and 115 V. C = $ 11.89
It means that the condensing unit power amounts to 2185 watts (9.5*230), whereas the evaporator unit will generate 103.5 watts (9*115), making a total of 2288.50 watts in total:
TW = 2185 + 103.5 = 2,288.50
Then converted in Kilowatts, it gives 30.42 ((2,288.50) x 16/1,000). Finally, multiplying this result by $11.89 produces the total cost of $132.44 for these units:
((((2,288.50)*16)/1,000)*30.42)*$.1189 = $132.44
These equations give you a general notion of the cost of your walk-in. However, they do not represent exact figures. To gain more precise total costs, consulting with a specialized expert to assist with the design and estimation of your walk-in setup is recommended.
