Refrigerator Overview

A typical two-temperature refrigerator. Freezer on the upper door and cooler on the lower door.

Home appliances and equipment directly impact our lives in varied ways. While others are essential, some are so vital that without them, or if they malfunction, life tends to be halting. One such appliance is the Refrigerator.

The term Refrigerator is generally used to refer to a machine used for keeping edible and non-edible stuff at low temperatures for the sake of preservation. Although the word “refrigerator” is used to refer to cooling equipment, there is a variety of refrigerators for particular temperature needs. So the name Refrigerator is ambiguous.

The name refrigeration industry uses to refer to a specific type of refrigerator precisely distinct it and removes ambiguity surrounding the word refrigerator. So if you are out shopping for one, knowing what a name specifically means is handy. There is Deep Freezer refrigerator, Refrigerator, and Cooler refrigerator. A Deep Freezer Refrigerator (or simply Freezer) is for keeping items at temperatures below zero. Highly perishable foods like fish and beef are kept well frozen in a freezer and can stay fresh for months in a frozen state. Mostly, a deep freezer is made of a single compartment – either Chest freezer or Upright freezer. Chest freezer opens with the door swinging upwards while an upright standing freezer has its door hinges vertical. These different door features don’t add to a freezer’s efficiency but only satisfies customer taste.

We then have a Refrigerator. A refrigerator has a freezer and a cooler combined in a single unit. The cooler part is basically designed not to cool anything inside its compartment to a freezing point. Either of the compartments can be on top of the other. A refrigerator with a freezer on top is known as a Top Freezer Refrigerator, while the one with the freezer on the lower compartment is called Bottom Freezer Refrigerator. In this category of refrigerators, there are different sizes designed for small and large families.

An ice cube maker and dispenser are built on some refrigerators. But as we will see, an ordinary refrigerator traditionally has only the basic parts to let it serve its purpose of keeping stuff at desired temperatures. Anything else is an added luxury that has its advantages and disadvantages.

Thirdly we have a Cooler Refrigerator. A cooler is a type of refrigerator that maintains temperatures above freezing point. They are also available in Chest and Upright models, with various sizes ideal for small and large families. Food stuffs like fresh vegetables, fruits, bottled drinks, and salads are well preserved above zero degrees.

Homeowners have the choice of furnishing their kitchens with coolers permanently fitted in their kitchens in the form of pull-out drawers. These kinds are ideal for stocking fresh farm produce.

When analyzing refrigerators, not only home users benefit. But also business owners because most of the refrigerators designed for the home are also applicable in the business set-up. All refrigerators operate on the same technical principles such that to make a choice, a potential buyer has just a few specific vital technical details to weigh before making a purchase. An example of one aspect to consider is electrical power consumption. Or gas consumption in case you opt for an “absorption system” refrigerator.

Kitchen refrigerators, and mostly freezers, use less energy compared with business showcase refrigerators. The simple reason is that a kitchen freezer is most of the times under lock and key. No frequent opening and closing to remove foodstuff, thus minimum energy is lost. On the contrary, a business showcase refrigerator is regularly opened and closed during business hours, making it necessary to have a quicker means of replenishing the energy lost while the door was opened. Obviously, such a refrigerator consumes more energy than the kitchen one. We will be looking in-depth characteristics of every type of refrigerator. We’ll touch on physical features designed for user operation and technical ones whose durability relies on how keen a user handles the refrigerator.

The ultimate goal is to know the basics of how to handle a refrigerator so as to get its service without unnecessary disruption.
