What is an industrial refrigeration system?
Industrial refrigeration can be defined as the equipment and accessories projected to remove heat from large-scale processes or materials, lowering the temperature to a desired value.
What is the introduction of refrigeration?
Refrigeration is the process of removing heat from an area or a substance. It is usually done by an artificial means of lowering the temperature, such as by the use of ice or mechanical refrigeration, which is a mechanical system or apparatus, designed and constructed to transfer heat from one substance to another.
How does an industrial refrigeration compressor work?
Modern Refrigerants A compressor pumps the refrigerant through evaporation coils, and condenser coils. Refrigerant becomes a gas (absorbs heat) in the evaporator and returns to liquid in the condenser unit, where it loses its heat. In fact, a condenser fan blows heat from the condenser coils.
What are the 4 process of refrigeration?
A refrigeration cycle has four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components in the refrigerant loop.
What are the properties of refrigerant used in industrial refrigeration?
Physical Properties of Refrigerants
- Low Freezing Point. Refrigerants should have low freezing point than the normal operating conditions.
- Low Condensing Pressure.
- High Evaporator Pressure.
- High Critical Pressure.
- High Vapor Density.
- High Dielectric strength.
- High Latent Heat of Vaporization.
- High Heat Transfer Coefficient.
What is part of industrial refrigeration cycle?
When the temperature of the system increases the refrigerant becomes a vapor, and when the pressure of the vapor increases, it becomes hot. When the refrigerant vapor cools, it converts back to its liquid state, and when it loses pressure, it cools further.
What is the purpose of refrigeration?
Refrigeration, or cooling process, is the removal of unwanted heat from a selected object, substance, or space and its transfer to another object, substance, or space. Removal of heat lowers the temperature and may be accomplished by use of ice, snow, chilled water or mechanical refrigeration.
What is the purpose of a refrigeration system?
Refrigeration systems are an essential process in industry and home applications as they perform cooling or maintain room temperature at a desired value. A cycle of refrigeration consists of heat exchange, compression and expansion with a refrigerant flowing through the units within the cycle.
What is the cycle of refrigeration?
The refrigeration cycle, sometimes called a heat pump cycle, is a means of routing heat away from the area you want to cool. This is accomplished by manipulating the pressure of the working refrigerant (air, water, synthetic refrigerants, etc.) through a cycle of compression and expansion.
What are the principles of refrigeration?
The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation are the main principles of the refrigeration process, or cycle.
What is the role of refrigerant?
Your system’s refrigerant runs between the two units of your air conditioner: the inside unit and the outdoor unit. Inside your air conditioner is a coil called the evaporator coil. Its function is to evaporate the refrigerant in order to absorb heat from the surrounding area.
Why is refrigerant used?
Refrigerant is a chemical compound used in your air conditioner. It absorbs environmental heat and provides cool air once it runs through compressors and evaporators.
What are the industrial applications of refrigeration?
Industrial refrigeration applications are typically used in places like cold food storage, dairy processing, Beverage production, Ice rinks and heavy industry, these sorts of places. These are large scale cooling systems.
Where do we find industrial refrigeration systems?
Where do we find industrial refrigeration systems? Industrial refrigeration applications are typically used in places like cold food storage, dairy processing, Beverage production, Ice rinks and heavy industry, these sorts of places. These are large scale cooling systems.
How does a refrigerant system work?
Another stream of refrigerant comes off the main line and is sprayed into the tank via an expansion valve to produce a cooling effect, as it is sprayed and evaporates in the tank it cools the submerged coil. This sub cools the main flow of refrigerant inside the coil before it flows to the main expansion valve.
What happens to the refrigerant in a refrigerant pipe?
The refrigerant is sealed inside the pipe and doesn’t come into contact with the air or water, it is always separated the two never meet or mix. Only the heat of the refrigerant passes through the pipe wall and is carried away by the air and water. As the heat is removed the refrigerant condenses into a liquid.
