How to make food last longer? It’s an all-encompassing question that people have been trying to solve for many years. Food preservation plays an important role in our homes, especially in our refrigerators. When it comes to storing fresh foods, it can be concerning to see your perishable foods deteriorating at a quick rate. Proper food preservation is important for many reasons, including, preserving the nutritional quality of your food, reducing food waste, preserving flavor, and maintaining proper food safety. Today we are going to look at the different refrigeration technologies that refrigerator manufacturers have created to make preserving foods easier and more efficient.
The various types of refrigeration technologies on the market today can have a high impact on the preservation of foods, from energy-efficient solutions, shelf life, food quality, the safety of your food, sustainability, and much more. Today, we are going to cover the different types of technologies most commonly equipped in refrigerators to help improve your food preservation, which are, dual evaporators, dual compressors, humidity control features, and advanced cooling technology.
As the name suggests, dual evaporators use two different components to maintain food freshness in your fridge. It uses two separate evaporator coils and fans to independently cool both the refrigerator and freezer sections of your fridge, ensuring both areas of your refrigerator maintain the proper cooling temperature for the ideal preservation of perishable foods.
Benefits for Preserving Food Quality and Avoiding Cross-Contamination
✅ Temperature Control: With the independent evaporators and fans, a dual evaporator system then maintains independent temperature control of both sections of your fridge, both fridge and freezer, meaning you can set ideal temperatures for both compartments based on the needs of your specific foods, which also extends the shelf life of your perishable foods.
✅ Preventing Flavor Transfer: Another benefit of dual evaporators, is that you don’t have to worry about a transfer of flavors from one compartment to another. With the separate cooling systems, the amount of airflow is minimal between the two sections, meaning there is less risk of mixing odors and flavor from improper airflow.
✅ Temperature Recovery: With dual evaporator refrigerators, temperature recovery is a breeze when either the refrigerator or freezer doors are opened, ensuring that the temperature is brought back to the ideal setting once the door is shut, preserving the freshness and longevity of your food.

Compressors are used in both refrigeration and air conditioning units, and their main job is to compress and circulate unwanted gas and heat out of the cooling system, to maintain proper cooling. With dual compressor refrigerators, you get two compressors that function within one unit, while maintaining separate functions. Generally, one compressor is used to support the cooling in the central area of the refrigerator, while the other compressor is used to provide cooling to additional cooling zones or the freezer compartment. This is especially helpful with the cooling of crisper drawers because the dual compressors can maintain ideal temperatures within each compartment without affecting the temperature of the rest of the fridge.
Impact on Energy Efficiency and Temperature Control
As stated above, dual compressors are great for creating the ideal temperatures for individual compartments within your refrigerator, such as for your fruits or veggies, meat and dairy, and more. Because each compressor works individually to maintain temperature control, the compressors do not work overtime, making your refrigerator more energy-efficient and sustainable.
Humidity control features are essential for preserving the quality and flavor of your food. With advanced humidity controls, the level of moisture is regulated in specific cooling regions, most commonly your crisper drawers, that create an ideal environment for various types of foods like fruits, vegetables, dairy, and meat. Vegetable drawer humidity and fridge humidity for fruit vary because the foods are different, and ripen or spoil at different rates, so with humidity control features, you can maintain the life of both with ease.
Benefits of Adjustable Humidity Drawers for Different Types of Produce
With adjustable humidity drawers, you have the power to create the ideal environment for your food based on the nature of your produce. For leafy greens, herbs, or berries, a high-humidity environment will elongate crispness and prevent wilting, while for produce like apples, root vegetables, or citrus-based fruits, a low-humidity environment will prevent an excess amount of moisture that can cause quicker ripening.
Over the years, refrigerator manufacturers have learned and perfected the best ways to keep our refrigerators at their ideal temperatures, by incorporating efficient cooling technologies like dual evaporator systems, variable speed compressors(inverter compressors/dual inverter refrigerators), energy-efficient insulation, multi-zone cooling, advanced air circulation, adaptive defrosting, and much more.
Benefits of Uniform Cooling and Temperature Consistency
✅ Maintenance of food safety
✅ Preserving food quality
✅ Prevention of flavor transfer
✅ Ideal organization capabilities
✅ Extended shelf life of food

Proper Storage Techniques
✓ Utilize designated compartments for specific items. For example, crisper drawers for fruits and vegetables (low humidity for fruits, high for veggies), deli drawers for deli meats, door shelves for sauces, beverages, etc., and meat drawers for your raw beef, seafood, and poultry.
✓ Avoid overcrowding your fridge.
✓ Use plastic wrap or airtight containers to store leftovers or open packages to prevent odors or moisture from spilling out.
✓ Keep temperature settings between 35°F and 38°F.
How to Store Different Types of Foods for Best Results
- Store milk, cheese, and other dairy products in the middle of your fridge where temperatures are more consistent.
- Store greens and herbs in a plastic bag with a paper towel, and then place in a crisper drawer. The paper towel absorbs excess moisture.
- Place any raw meat on a tray or in a container before putting it in your fridge to catch any potential juices that could cause cross-contamination, and place the meat in a designated meat drawer, or bottom shelf.
- Keep eggs in their original packaging and place them on the middle shelf.
- Utilize crisper drawers for fruits and vegetables.
Regular cleaning and defrosting of your refrigerator can help you enjoy a longer, more efficient refrigerator. Cleaning the inside of your fridge like shelves, drawers, and more, improves the overall health of your fridge while cleaning the coils of your refrigerator improves the cooling efficiency and heat exchange. Regularly defrosting your freezer is necessary for preventing ice build-up, which preserves food quality, maintains your refrigerator’s energy efficiency, and prolongs the life of your fridge.
On top of regular cleaning and defrosting, be sure to change air filters and check door gasket seals. Change the air or water filters based on the manufacturer's recommendations, and check the door gasket seals to ensure that your fridge door is closing properly with an airtight seal.
In conclusion, choosing a refrigerator with the right cooling technology is vital to the overall reduction of food waste in our home, food preservation, and food safety. If you want to invest in a refrigerator that has advanced cooling technologies, but are hesitant, don’t wait! There is nothing more important than proper food maintenance and safety within our homes, and thankfully, there are innovative features and technologies available right at our fingertips.
