How to Choose a Refrigerator
Refrigerators are kitchen appliances utilized to keep food and drinks cold. They are commonly used in homes and in hotels, offices, and college dorm rooms.
Some refrigerators have smart features, like sensors and cameras. Some refrigerators are equipped with touchscreens that let you view videos and search for recipes, view family calendars and shopping lists. You can also leave notes.
Temperature Control
The right refrigerator temperature ensures food safety and will prevent loss. This is particularly important with food such as eggs and milk which quickly turn rotten at ambient temperatures however, they remain stable in refrigerator temperatures. Refrigerators are also widely used to store pharmaceuticals like vaccines and medicines that become less effective as time passes. Refrigerator monitoring systems can ensure that a medical facility, laboratory or other institution has the cold chain.
A refrigerator has an internal thermal insulator to keep its contents colder than the surrounding air. The heat pump is used to move warm air from outside the refrigerator to an insulated compartment, where it cools to a very low temperature. The refrigerator also has a control system that turns on the cooling system when its internal temperature rises above a pre-set threshold. This prevents bacteria from growing in the refrigerator.
Each refrigerator zone is designed for a different purpose. The bottom shelves are perfect for perishables like fresh vegetables and meats that require the minimum temperature to keep their texture and taste. The shelves must be kept clear in order to allow cool air to circulate in the refrigerator. A separate deli drawer can be used to store soft cheeses and cured foods for the perfect charcuterie platter.
Refrigerators also feature glass or stainless steel doors to protect the interior and allow for easy cleaning. Some refrigerators also include door alarms that can be programmed to warn you if the doors to the freezer or fridge are closed for too long. You can set them up to alert multiple people and in increments based on your requirements. They can also be programmed to record temperature and send graphs remotely via email or text.
Most refrigerators have built-in thermometers however, for those who don't, a stand-alone appliance thermometer is a cost-effective method of monitoring the temperature of your freezer and fridge. It is essential to check the temperature of the fridge and freezer frequently, particularly in the event of an outage in power or you've manually changed the temperature setting. Ideally, both the refrigerator and freezer should be set to 40 degrees Fahrenheit or below.
Capacity of Storage
The capacity of the refrigerator is a crucial aspect to consider when choosing the best model for your needs. There are many sizes available, from small models with a capacity less than 15 cubic foot to larger models that can hold more than 26 cubic feet. Consider your family's cooking style and the number of people living in your house to determine the best size for you. On average, 11 to 13 cubic feet of refrigerator space is adequate for two people. 18 to 22 cubic feet are recommended for three to four people.
Check the depth of the fridge in addition to the space. Some models are more shallow than others, which allows them to fit into tight spaces without taking up too much space under the counters. Cabinet-depth refrigerators are another option, having a depth that is roughly the same as the standard kitchen cabinet's front (though handles might protrude a bit further). These are a good option for homes with limited counter space. They also appear more modern.
Ask about the refrigerator's energy usage and noise level when shopping. There are many manufacturers that offer quieter refrigerators suitable for residential use. Some offer refrigerators with less energy consumption than comparable models. Check american fridge on appliances to learn about the typical energy consumption for the specific model. Also, test the model's operation by closing and opening the doors.
The pantry drawer is typically an entire width of the refrigerator, with separate temperature controls. It can be used to store a variety things. These drawers can be used to store trays for parties wine, other food items and more at a certain temperature. They can be programmed to hold wine as well as deli food items, and soft drinks, depending on the model.
Energy Efficiency
Refrigerators consume a lot electricity. This is why it's important to have one that is energy efficient. The good news is that refrigerators are becoming more energy efficient over the years. Insulation, motors, as well as magnetic door seals have all improved over time, which means that a modern refrigerator consumes less power than a previous model of the same size. It is possible to reduce the refrigerator's electricity consumption even further by purchasing a highly energy efficient model. A refrigerator with an Energy Star rating will use less energy than a model that is 10 years old or older.
Efficiency in energy is crucial for consumers with limited access to electricity grids. Refrigerators are typically among the most costly appliances for off-grid households, and their high energy consumption means that they require large solar home systems (SHS) which aren't affordable for families earning less than $2 per day. The annual energy usage of a refrigerator is a key factor to determine whether it's economically feasible for consumers to purchase and operate. (PATH and WHO 2013, McCarney and. al. 2012).
To understand how refrigerators function it is important to understand the fundamental refrigeration cycle. The refrigerator cools down by pushing a refrigerant fluid through a sealed system. It starts out as a liquid, and passes through the compressor which reduces it to a vapour. The vapor then flows through coils located on the exterior of the fridge, where it draws the heat from the fridge, cooling down before returning to the liquid. This process is repeated repeatedly to keep food cool as the vapor circulates through the coils.
Refrigerators are still among the most expensive appliances that consumers who are not connected to the grid can purchase, but improving their energy efficiency will make them more affordable. By reducing the amount of energy they use, a refrigerator can be powered by an enlarge SHS, which will reduce the overall cost of the system for consumers. Depending on the size, style and features of the refrigerator, energy savings will vary. For instance, ice-makers and through-the-door water dispensers increase cost but may significantly increase the refrigerator's energy consumption and, in turn, increase the SHS required to power it.
Maintenance
The lifespan of a refrigerator could be significantly improved by regular maintenance and inspection. Examine the condenser, defrost drain and ice maker. Also, make sure you check the seals on the door. Cleaning and replacing the water filter is also vital. Doing these simple tasks can prolong the lifespan of your fridge and reduce your energy costs.
Cleaning the inside of your fridge on a regular basis is the easiest and most efficient way to keep it in good condition. This includes throwing away old food items, wiping down shelves and crispers, walls and the interior of your refrigerator's doors. This will lower the risk of foodborne illnesses and unpleasant smells. It is also recommended to periodically check the temperature of your refrigerator by using the help of a thermometer for your fridge. A refrigerator that isn't properly maintained may experience temperature fluctuations, which can lead to food spoilage as well as a higher cost of electricity.
The condenser coils of your refrigerator should be cleaned at least at least twice a year. This will get rid of any dirt, grime, hair or other debris that has built up. These coils, which are basically radiators that help to remove heat from the refrigerator, are located in the rear or bottom of your appliance. These coils can't dissipate heat as efficiently when they're dirty. Your refrigerator will use more energy to run.
Check the seal on your refrigerator, which is designed for an airtight seal between your fridge and the ductwork that runs through your home. This is essential to ensure your fridge's contents remain cool But over time, the seal could wear down from greased fingerprints, sticky syrups, and dripping beverages. To keep the gasket of your refrigerator in good condition, frequently clean it with the help of a damp cloth.
It is also a good idea, to clean the drip tray, which is located typically beneath the compressor unit of the refrigerator. This pan is used for collecting the water from the refrigerator's defrost cycle. It should be cleaned frequently to prevent the development of mold and unpleasant smells.
