Thermoacoustic refrigeration uses sound waves and helium gas to create cooling power, eliminating the need for mechanical components and ozone-depleting gases. Developed at Penn State University, it is more environmentally friendly and requires less maintenance than traditional refrigeration. The final working prototype was unveiled at Ben & Jerry’s Waterbury, Vermont facility during Earth Day in […]
Vapor-compression refrigeration uses a liquid refrigerant to absorb and remove heat from a space. The cycle includes a compressor, evaporator, condenser, and throttle valve. It is used in home appliances, air conditioning, transportation, and industrial settings with an efficiency of up to 60%. Vapor-compression refrigeration is a refrigeration system that uses a circulating liquid refrigerant […]
Industrial refrigeration units use different refrigerants, including anhydrous ammonia, carbon dioxide, and propane. Anhydrous ammonia is common due to its excellent heat transfer capabilities and environmental friendliness. Carbon dioxide cools food rapidly, while propane is mostly used in refineries. When choosing a unit, consider safety, size, ease of installation, and usability. Buy in person and […]
Commercial refrigeration units are used by various industries, including restaurants, florists, and food processing companies. The most common types are walk-in refrigerators and freezers, display cases, and refrigerated warehouses. These units are designed to retain cold air and reduce the need for chemicals, making them more energy-efficient and cost-effective. There are several common types of […]
Mobile refrigeration is used to transport goods and organisms at a stable cool temperature. It is used for food safety, medical supplies, recreational purposes, disaster response, and more. Companies sell various mobile refrigeration equipment and offer maintenance services. Mobile refrigeration is a form of refrigeration designed specifically to meet the refrigeration needs in mobile environments. […]
Refrigeration jobs include appliance installation, commercial installation, maintenance, and sales, all requiring at least three years of post-secondary training. These jobs require mechanical and electrical skills, physical aptitude, and good interpersonal skills. Promotional opportunities vary depending on the industry and role. Women are increasingly finding success in the field. Typically, four different types of refrigeration […]
Refrigeration courses are available for licensed mechanics and general interest, with most offered as part of an HVAC program. Professional courses include specialized tools and computer simulations, and should be taught by experienced instructors. Vendor-specific training sessions are also available for maintaining complex systems. When selecting a refrigeration course, take the time to assess your […]
Refrigerators have come a long way since William Cullen’s first model in 1755. Jacob Perkins invented the practical refrigerator in 1834, and since then, refrigeration units have evolved significantly. The compressor is the most important part of the refrigeration process, and refrigerant or ammonia is used to cool the refrigerator. Heat exchange coils inside and […]
Refrigeration tools such as leak detectors, pipe benders, cutters, press and flare fixtures, and charging valves are essential for repairing and maintaining refrigeration equipment. Leak detectors and finders detect and locate leaks, while pipe brushes and heavier tools repair or replace pipes. Flaring and flaring tools join wires and pipes, and charging valves are model-specific […]
Refrigeration engineers and technicians use refrigerant charging and recovery equipment to work with refrigeration systems. They use tools such as thermometers, leak detection equipment, vacuum pumps, and refrigerant identifiers to diagnose and repair systems. The use of refrigerant equipment and gases is strictly monitored due to their potential danger. Refrigeration engineer and refrigeration technician work […]
Restaurant kitchens have various types of refrigeration depending on the size and food served. Handy, reach-in, walk-in, air curtain, display cases, ingredient stations, and drink dispensers are common types. They are designed to hold specific items and keep them cool. Restaurant kitchens contain a wide variety of types of refrigeration which can depend on the […]
To become a refrigeration technician in the US, an associate’s degree or substantial work experience is required. Technical certifications and 2-3 years of experience are preferred, and basic math and computer skills are necessary. Communication and problem-solving skills are also important. To become a refrigeration technician in the United States, you may need to have […]
Refrigeration engineers install and service refrigeration systems for commercial buildings, delivery trucks, and homes. They may specialize in industrial-sized refrigeration systems, refrigerators, or household units. They typically complete a two-year training program and work as apprentices for up to four years before passing licensing and certification exams. Special certification is required for those who handle […]
