Refrigeration definition

The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration definition , the act or process of refrigerating. A compressor is a component of a refrigeration system that pumps refrigerant and increases the pressure of the refrigerant vapor. Noun (countable and uncountable, plural refrigerations) 1. The process of transferring heat from an object in order to cool it.


English dictionary definition of refrigerator.

An appliance, cabinet, or room for storing food or other substances at a low temperature. Examples of refrigerator in a Sentence. The cooling of a space or substance below the environmental temperature.


The system of refrigeration can be cyclic, non-cyclic,thermoelectric or magnetic depending on the application for which refrigeration is needed. Mechanical refrigeration , often referred to simply as refrigeration , is a process by which heat is removed from a location using a man-made heat-exchange system. One of the most efficient refrigeration cycles is the reverse Carnot cycle, which is approximated by the refrigeration cycle of an ideal vapor-compression refrigerating machine, as shown in Figure 1. The ideal vapor-compression cycle consists of two adiabatic processes (1–and 3–4) and two isothermal processes (2–and 4–1). A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.


Based on the heat of fusion being 333.

Thus, tonne of refrigeration is larger than ton of refrigeration. Definitions of Section 6Terms. EPA interprets this definition to include all air-conditioning and refrigeration equipment except that designed and used.


Fluid is any substance that can flow, liquid or gas. Refrigerant may be classified as flui since, within the refrigeration cycle, it exists both as a liquid and as a vapor or gas. Similarity: There is no true definition of darkness, other than the absence of light. Energy is the capacity of a system to do work where system refers to any physical system, not just a refrigeration system.


I called the vice president of engineering at three different compressor manufacturers and asked where the term refrigeration horsepower came from. The good news is I got the same answer from all three of them. Keep all meat products under refrigeration. The refrigeration industry has long since utilized this definition.


Also called a suction accumulator. The work of heat transport is traditionally driven by mechanical work, but can also be driven by heat, magnetism, electricity, laser, or other means. It is your guarantee that the products’ energy-efficiency ratings have been independently verified by a third party. Why are precautions necessary in the use of ice for refrigeration ? What effect does refrigeration have upon the composition of food?


Other refrigeration ” means any stationary, non-residential appliance that is used for an application other than industrial process refrigeration , commercial refrigeration , or air-conditioning, or is used for two or more applications including industrial process refrigeration , commercial refrigeration , or air-conditioning. Industrial refrigeration can be defined as the order from the factory to provide cooling for the large-scale processes. British thermal units (Btu) per hour 2Btu per minute and denotes the amount of heat required to melt one ton of ice in hours.

Commonly used to measure the temperature of the liqui suction and discharge lines. The amount of heat required to melta ton of ice at degrees F. In the case of freezing, the. The most widely used refrigeration cycle is the vapor-compression refrigeration cycle. Not only are there a lot of different types of commercial refrigeration , the freezers and fridges out there come in a wide range of sizes. Depending on the unit, this ventilation could be located on the bottom or side of the unit.


They can work on industrial or residential climate-control systems, such as HVAC units, ice machines, beverage equipment and refrigerated storage units. Compression system is more popular than absorption system. Whether you’re looking to repair, replace or maintain your air conditioning system, Make the Right Choice and give us a call today. These slides may be updated in the future, with or without notice.


Auto- refrigeration is a phenomenon common to liquefied compressed gases. Liquefied compressed gases exist in both the liquid and gaseous phases at ambient temperatures with pressures ranging from psig up to 5psig. This is the definition of ton of refrigeration. See the reference to Class in the definition of subclass of Class 165. OIL IN REFRIGERATION SYSTEMS FIGURE 1. LOSS OF CAPACITY WHEN OIL IS PRESENT IN R-12.


However, in a refrigeration system, oil is carried through the compressor by the refrigerant. It circulates with the refrigerant throughout the system. A small amount of oil in circulation is not harmful.


The normal strategy in mechanical refrigeration is to get the heat to the refrigerant. Learn vocabulary, terms, and more with flashcards, games, and other study tools. They use compression to raise the temperature of a low-pressure gas, and also remove vapor from the evaporator.


This feature is not available right now. The main purpose of refrigeration is thermal conditioning (e.g. for food preservation or air conditioning), and the basic apparatus is a refrigerator, a thermal machine producing cold. A refrigeration safety awareness specialist is not trained to repair any machines in the plant, but is employed solely to ensure that all personnel are able work in a safe manner and evacuate the plant if need be. Shop commercial refrigerators, commercial freezers, ice cream equipment and prep tables at WebstaurantStore, your refrigeration resource.
