Anatomy of a Sub-Zero Refrigerator: A Visual Guide
Sub-Zero is a brand of high-end refrigerators that are designed to keep your food fresher for longer. Sub-Zero refrigerators use dual refrigeration, which means they have two separate cooling systems for the refrigerator and freezer compartments. This prevents the transfer of odors, flavors, and moisture between the two sections, and also allows for more precise temperature and humidity control. Sub-Zero refrigerators also have advanced features such as microprocessor control, air purification, water filtration, and ice making. In this article, we will take a look at the anatomy of a Sub-Zero refrigerator and explain how each part works. For Sub-Zero servicing in Santa Ynez, please contact our recommended experts.
The Door, Grille, and Trim
The door of a Sub-Zero refrigerator is made of stainless steel or custom panels that match your kitchen cabinets. The door has a magnetic seal that prevents cold air from escaping and warm air from entering. The door also has a handle, hinges, gaskets, shelves, bins, and an alarm that alerts you if the door is left open for too long. The grille is located at the bottom of the refrigerator and covers the condenser fan and coil. The grille allows air to flow in and out of the refrigerator and helps to dissipate heat. The trim is the decorative frame that surrounds the refrigerator and gives it a sleek and elegant look.
The Refrigerator Interior
The refrigerator interior is where you store your fresh food items such as fruits, vegetables, dairy products, meats, and beverages. The refrigerator interior has several parts that help to preserve your food quality and freshness. These include:
- The shelves: The shelves are made of glass or metal and can be adjusted to accommodate different sizes and shapes of food containers. Some shelves have spill-proof edges that prevent liquids from dripping onto other foods. Some shelves also have LED lighting that illuminates the food items without generating heat.
- The drawers: The drawers are located at the bottom of the refrigerator and are used to store fruits, vegetables, meats, cheeses, and other items that require higher humidity levels. The drawers have adjustable dividers that allow you to organize your food items according to your preference. Some drawers also have temperature controls that let you set the optimal temperature for different types of foods.
- The bins: The bins are located on the door of the refrigerator and are used to store smaller items such as eggs, butter, condiments, and beverages. The bins have clear plastic covers that protect the food items from dust and moisture. Some bins also have locks that prevent children from accessing them.
- The air purification system: The air purification system is a feature that removes ethylene gas, bacteria, mold, viruses, and odors from the air inside the refrigerator. Ethylene gas is a natural by-product of ripening fruits and vegetables that can cause other foods to spoil faster. The air purification system uses a filter that contains activated carbon and zeolite to trap and neutralize these harmful substances. The filter needs to be replaced every year or as indicated by the control panel.
- The water filtration system: The water filtration system is a feature that removes chlorine, sediment, lead, cysts, and other contaminants from the water that is used for drinking and ice making. The water filtration system uses a filter that is located behind the grille or inside the refrigerator. The filter needs to be replaced every six months or as indicated by the control panel.
- The ice maker: The ice maker is a feature that produces crescent-shaped ice cubes from filtered water. The ice maker has a storage bin that holds up to 4 pounds of ice cubes. The ice maker also has an automatic shut-off feature that stops making ice when the bin is full or when the door is open.
The Freezer Interior
The freezer interior is where you store your frozen food items such as ice cream, meat, fish, vegetables, and prepared meals. The freezer interior has several parts that help to maintain your food quality and freshness. These include:
- The shelves: The shelves are made of metal or wire and can be adjusted to accommodate different sizes and shapes of food containers. Some shelves have LED lighting that illuminates the food items without generating heat.
- The baskets: The baskets are located at the bottom of the freezer and are used to store bulkier items such as large cuts of meat or bags of frozen vegetables. The baskets have handles that make it easy to pull them out and access your food items.
- The defrost system: The defrost system is a feature that prevents frost build-up on the walls and coils of the freezer. Frost build-up can reduce the efficiency and performance of the freezer and cause freezer burn on your food items. The defrost system uses a heater and a timer to melt the frost periodically. The melted frost then drains into a pan under the refrigerator where it evaporates.
The Systems View
The systems view is where you can see the components that power and control your Sub-Zero refrigerator. These include:
- The compressor: The compressor is the heart of the refrigerator that pumps refrigerant through the cooling system. The compressor is located behind the grille or under the refrigerator and is controlled by the microprocessor. The compressor has two functions: to compress the refrigerant from a low-pressure gas to a high-pressure gas, and to circulate the refrigerant through the condenser and the evaporator.
- The condenser: The condenser is the part of the refrigerator that releases heat from the refrigerant to the surrounding air. The condenser is located behind the grille or under the refrigerator and consists of a coil and a fan. The coil is a series of tubes that carry the high-pressure refrigerant gas from the compressor. The fan blows air over the coil to cool it down and turn the refrigerant gas into a liquid.
- The evaporator: The evaporator is the part of the refrigerator that absorbs heat from the interior of the refrigerator and freezer. The evaporator is located inside the refrigerator and freezer compartments and consists of a coil and a fan. The coil is a series of tubes that carry the low-pressure refrigerant liquid from the expansion valve. The fan blows air over the coil to warm it up and turn the refrigerant liquid into a gas.
- The expansion valve: The expansion valve is the part of the refrigerator that regulates the flow of refrigerant from the condenser to the evaporator. The expansion valve is located near the evaporator and is controlled by the microprocessor. The expansion valve has two functions: to reduce the pressure of the refrigerant liquid, and to meter the amount of refrigerant liquid that enters the evaporator.
- The microprocessor: The microprocessor is the brain of the refrigerator that monitors and adjusts the temperature, humidity, defrost, air purification, water filtration, ice making, and other functions of the refrigerator. The microprocessor is located behind the control panel and communicates with sensors, switches, valves, fans, heaters, and other components. The microprocessor also displays information such as temperature settings, filter status, door alarm, service indicator, and error codes on the control panel.
