Refrigerators

The actual history of modern day refigerators using safe methods of cooling and keep food frozen was invented in the U.S.A in the 1920's, using a gas called freon. Before that time numerous methods were used to keep food cooled or frozen. Some of the earlier methods include, methyl chloride and sulfur dioxide, which proved to be fatal. Other early methods of refrigeration include using ice blocks to keep food cold and preserved.

how do they work?

Older refrigerators uses Freon gas. The liquid gas is pumped through coils located at the back of the unit, the liquid turns into vapours, these vapours soak up any heat that might be present in the freezer compartment. After this process the system pumps out the freon vapours into another set of pipes, from there it goes through the whole process of going through the coils and cooling your food.

New fridges are different in how they work. After Freon gas was found to be dangerous if the coils leaked a new system was formed, the use of ammonia gas. Ammonia transforms into a liquid gas when it is cooled to -6.5 degrees celsius. This liquid gas is squeezed through coils, that are located at the back of the fridge. The colder ammonia in the coil then pulls the heat out of the compartments. This system creates the cold temperature in the fridge.

types

There are a few different types to choose, depending on your needs as well as budget

• side by side - this type of fridge is designed with the freezer and refrigerator next to one another, these unit are larger than bottom or top freezers models. If you have a large family and you have the space in your kitchen this is perfect.
• compact (mini) refrigerator - If you live in a small space such as a bachelor apartment then this might be for you.
• wine cooler - designed to keep all your favorite wines cool

features to consider when shopping around

Below are some of the features to take into consideration when reviewing & rating the various models available.

• total volume - this definition refers to the size and capacity of the fridge
• ice maker & dispenser - with a press of the button you can have fresh ice for cold drinks
• digital display
• stainless steel exteriors are very popular because of the modern look
• built in water purifier - there is no need to buy water anymore, these refrigerators have water purifiers built right into them, so you can enjoy purified water right from your fridge

other tips on features to look include

• Make sure the shelves are strong, some models have thin plastic shelves that can easily break after normal use. I recommend purchasing a unit that has tempered glass shelving, with a raised rim to contain spills
  
  
• Another important feature is the ability to control certain areas inside your fridge separately, such as your vegetable crispers, as well as meat and deli drawers.
  
  
• Another point is to ask the salesperson to actually plug in the refrigerator so you can hear the noise volume, you want to find the quitest machine possible.
  
  
• find a unit that has pull-out freezer bins for easy access.
  
  
• transparent see through drawers are great so you can see what’s inside the drawer
  
  
• find a fridge that has temperature-controlled drawers, for each bin. This will give you control over the temperature in each drawer with individual controls to set the interiors of these several degrees cooler for storing meat or fish. Veggie crispers have separate controls to maintain humidity and provide longer produce and fruit shelf life
  
  
• want to save money on purchaing a seperate purified water machine, then a refrigerator with an in-door ice-and-water dispenser will give you purified cold water and ice whenever you need it
