Refrigerator definition and uses

The Refrigerator is the cooling household appliance system where removing the heat from the system to surrounding by the heat pump so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room Refrigerator definition, a box, room, or cabinet in which food, drink, etc., are kept cool by means of ice or mechanical refrigeration. See more / rɪˈfrɪdʒ.ə.reɪ.t̬ɚ / (UK usually fridge) A1 a piece of kitchen equipment that uses electricity to preserve food at a cold temperature: Store fruit juice in the refrigerator (Chemical Engineering: Heat transfer) A refrigerator is a device which uses the boiling and condensation of a refrigerant to cool something. A regular refrigerator uses a compressor to increase the pressure on the gas, and then condenses the higher pressure gas back to a liquid by heat exchange with a coolant The equipment used for removing the heat continuously for maintaining a low temperature in a space is called 'refrigerator'

Industrial use of refrigeration Industrial refrigeration can be defined as the order from the factory to provide cooling for the large-scale processes. In this book, the definition is limited to processes other than air conditioning or food and beverages In order to keep food fresh, a low temperature must be maintained in the immediate environment to reduce the reproduction rate of harmful bacteria. A refrigerator works to transfer heat from inside to outside, which is why it feels warm if you put your hand on the back side of fridge near the metal pipes - you'll find out how that works in a bit Here's how they interact to cool your food. 1. The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator. 2. When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. 3 A refrigerator is a serious purchase - after all, it's not often you buy something you intend on using every single day for at least the next ten years. We understand that anyone who's been out of the refrigerator-shopping game for a while may feel overwhelmed by modern icebox options, and we want to make sure you're well-informed before taking the (refreshingly cool) plunge into.

The Purpose of Refrigeration The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food Definition: Worktop refrigerators allow you to prep and work on food products to be completed while also storing the necessary ingredients for the product. They come in a variety of forms making them versatile while remaining at a comfortable working height

Refrigerator-Definition, Main Parts or Component, Working

RV refrigerators are available in two styles, either a compressor-powered refrigerator or an absorption refrigerator. Compressor-powered refrigerators sometimes referred to as two-way refrigerators use a small compressor unit to cool the refrigerator. Often they have two ways of powering the compressor either through 12-volt battery power or 110-volt power, hence the name two way refrigerator.
