The process of removing heat from a space or substance to reduce its temperature and transferring that heat to some another space or substance i.e. air or water. This is the technique by which we keep the temperature of the given space lower than its surroundings or environment. The heat is removed from the substance to be cooled and transferred to air, water or other cooling medium.To remove the heat from the given space we evaporate a volatile liquid by lowering its pressureDuring this process the liquid becomes vapor by taking heat from the system, making it cool.

What is the temperature ranges for low medium and high refrigeration applications?
Low refrigeration applications typically range from -50°C to -18°C, medium refrigeration applications range from -18°C to 0°C, and high refrigeration applications range from 0°C to 10°C. These temperature ranges may vary depending on the specific requirements of the application and the type of refrigeration system being used.
Why does refrigeration produce cfcs?
Refrigerators do not produce CFC. Old equipment contains these materials as they were the refrigerant of choice before the Montreal Protocol. The old equipment lost the CFCs to the atmosphere due to leaks and gasket failure.
What is cooling of air expansion caused by?
Cooling of air expansion is caused by adiabatic expansion, where the air moves into a larger volume with no heat exchange with the surroundings. As the air expands, it does work on its surroundings, leading to a decrease in temperature due to the conservation of energy principle. This process is often observed in various natural phenomena and industrial applications, such as in refrigeration systems and weather patterns.
When pressurizing a refrigeration system with nitrogen what rule should you always follow?
When pressurizing a refrigeration system with nitrogen, always follow the rule of not exceeding the recommended pressure limit specified by the manufacturer. Over-pressurizing the system can lead to potential safety hazards, and it is important to always refer to the manufacturer's guidelines to prevent any damage to the system.
What is cascade freezer?
A cascade freezer is a type of industrial freezer that uses multiple refrigeration cycles to achieve ultra-low temperatures. It typically consists of two separate refrigeration systems with different refrigerants, allowing for efficient cooling of products that require extremely low temperatures. Cascade freezers are commonly used in industries such as pharmaceuticals and food processing for preserving and storing sensitive materials.
Does Skippy's new Natural peanut butter need refrigeration?
Yes
What is the importance of ammonia detector while dealing with refrigeration system?
This type of detector is of no importance for electric powered refrigeration systems, as ammonia is not used in them. This type of detector is a safety device for natural gas and propane powered refrigeration systems as ammonia is the coolant in such systems and a leak of ammonia vapor is toxic.

What is a refrigeration technician?
You will be well aware that all the refrigeration systems used today needs regular maintenance. All the refrigeration equipment maintenance is carried out by a well trained refrigeration technician. Commercial refrigeration is found in every food processing establishment. Hence the demand for the refrigeration technicians is also high.

When was Institute of Refrigeration created?
Institute of Refrigeration was created in 1899.
What are the two types of refrigeration?
The two types of refrigeration are vapor compression refrigeration and absorption refrigeration. Vapor compression refrigeration is the most common type and is used in most household refrigerators and air conditioning systems. Absorption refrigeration, on the other hand, uses heat to generate a refrigerant vapor instead of a mechanical compressor.
