The refrigerator for the study is a L domestic frost-free side-by-side RF, of which the freezer volume is L. As shown in Fig. 1a, the freezer compartment is on the left RF has only one evaporator, mounted in back-side wall of the freezer by: 6. Food safety concerns dictate that perishable foods should be stored at temperatures lower than 40 degrees Fahrenheit. Since to degree temperatures are most energy efficient, the best temperature to choose for the refrigerator is 35 to 38 Fahrenheit.

United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park, NC Research and Development EPA//S/ Nov vxEPA Project Summary Review of Energy Efficiency of Refrigerator/Freezer Gaskets Majid Ghassemi and Howard Shapiro The report gives results of an inves- tigation of the significance of heat leak- age.
Freezers that have earned the ENERGY STAR are available from brands including Bosch, Danby, Frigidaire, GE, Jenn-Aire, Kenmore, and many more. Cut your utility bills. Freezers that have earned the ENERGY STAR are at least 10 percent more energy efficient than the minimum federal standard.
The older the freezer, the higher your bills. Ghassemi, Majid, "Effects of gasket heat gain and an alternative refrigerant on refrigerator/freezer performance " ().Retrospective Theses and Dissertations. The gaskets in a refrigerator/freezer act as seals to contain the cold air higher energy efficiency standards are providing considerable impetus to reduce gasket heat gain.
From the Manufacturer. Whirlpool Freezer Door Gasket for Refrigerator. Freezer Door Gasket. Works with models: ABPEKW, ABBDEQ, ABBDEW, ABBFEQ 5/5(2). The present study has been carried out to analyze the heat transfer characteristics and thermal load near the freezer gasket region of a L domestic frost-free refrigerator/freezer.
In a review by Ghassemi and Shapiro (), the energy consumption associated with the gasket heat transfer load varied from 10% to 30% of the unit total thermal load, and the gasket infiltration load ranged from to W (5 to Btu/h).
A new home or apartment that has earned the ENERGY STAR label has undergone a process of inspections, testing, and verification to meet strict requirements set by the US EPA. ENERGY STAR certified homes and apartments use significantly less energy than typical new homes and apartments while delivering better comfort, quality, and durability.
ENERGY STAR certified refrigerators are about 9 percent more energy efficient than models that meet the federal minimum energy efficiency standard. Replace your old fridge for bigger savings. An estimated million refrigerators and refrigerator-freezers are currently in use in the United States.

Recently, manufacturers are all clamoring for the blue Energy Star sticker and claim. By Energy Star requirements, a refrigerator must be at least 20% more efficient than the Federal Dept. of Energy minimum. Refrigerator-freezer combinations and standalone freezers typically require between and watts of energy to operate.
A side-by-side refrigerator-freezer combination uses almost twice that amount. Your electricity bill likely reflects this fact, as it can cost three times as much per month to run a side-by-side refrigerator than any other. Replacement Parts. Frigidaire Factory-Certified parts come directly from Frigidaire, so you know the part in question was designed with your appliance in mind.

The built-in .Refrigerators can have very different energy consumption depending on the year of manufacture and features that affect energy use such as size, automatic defrost, or side-by-side design.
In Home Energy Saver professional and consumer the energy consumption of these appliances is estimated, using the calculation method described in the Energy.If you add a joint refrigerator/freezer into the mix, this becomes quite tricky as the temperature gradient changes throughout the volume.
Given a ballpark figure of freezer part occupying 20% of the volume, and assuming the changed geometry doesn't influence it, I can give you a rough estimate of 10% energy savings when using a pure.
