Refrigerator cars, also known as reefers, are rail cars used to transport perishable foods at low temperatures. They were first used in the mid-1800s and evolved over time with the use of ice and improved insulation. The advent of Styrofoam and evaporative cooling systems improved efficiency, but the use of refrigerated freight cars declined in […]
Over 90% of Mexican households have a TV, while only slightly over 80% have a refrigerator. In 1990, 20% of homes had dirt floors, but by 2010, only 6% did. Only 65% of homes have a shower, and more families have a cell phone than a landline. Homes in Mexico are more likely to have […]
Refrigerated trucks transport perishable goods using ice or on-board refrigeration systems. They are used to transport food and other items that require a constant temperature, such as medication and archaeological artifacts. Refrigerated trucks are road vehicles used to transport goods considered perishable when subjected to higher temperatures. Trucks of this type use several different strategies […]
Refrigerated vans and rail cars keep perishable items fresh during transportation. They are used for food, flowers, and medicines. Refrigerated vans can be modified or rented, and some companies share resources. Badges and vents indicate refrigeration, and alarms alert engineers to any issues. The term “refrigerated van” can refer to a van equipped with refrigeration […]
Choosing the right RV refrigerator is important for successful camping trips. Factors to consider include power supply, size, and additional features. Replacement RV refrigerators may have fewer options, and careful consideration must be taken when choosing a replacement to ensure it fits in the same space. Portable electric refrigerators are also an option. Choosing the […]
The refrigerant compressor compresses refrigerant to cool a device. The refrigeration system uses environmentally friendly chemicals to transfer heat and cold efficiently. The compressor is critical and can fail, requiring repair or replacement by a certified technician. A refrigerant compressor is a component of a refrigerator designed to compress the refrigerant used to cool the […]
Refrigeration vacuum pumps remove moisture and air from AC/R systems by creating a deep vacuum, boiling water and expelling steam and air. They are typically rotary with two-stage operation and can produce values of 50 microns or less. It is important to use the correct size pump and maintain oil levels. A refrigeration vacuum pump […]
A refrigeration compressor compresses refrigerant using a piston, crankshaft, and connecting rod. It has intake and discharge valves, and uses reed valves. Compressors require a condenser and capacitor to start up. Some refrigerators have independent compressors for the fridge and freezer. A refrigeration compressor is an essential part of what makes refrigeration technology work. A […]
Absorption refrigerators use alternative heat sources like solar energy or kerosene to create energy for cooling. They are practical for personal use in RVs and remote cabins, and for commercial use in areas without electricity. Ammonia is used as fuel, making fuel consumption efficient. The concept dates back to the mid-19th century. An absorption refrigerator […]
An Internet refrigerator has a built-in computer on one of its doors, allowing access to the internet through a detachable touch-screen display. It offers entertainment options and practical features, such as temperature control and expiration date tracking. It also saves space and provides convenience for cooks. An Internet refrigerator, or a networked refrigerator, is an […]
Fridge cookies, also known as icebox cookies, are made by shaping cookie dough into a log or round and refrigerating it before slicing and baking. Homemade versions offer more control over ingredients. Refrigerated dough is also used for cookie rolling. Classic fridge cookies are not used for cutouts, but can be made into sandwich cookies. […]
Refrigerator thermometers provide real-time temperature information for the main compartment or freezing section. Modern models have digital readouts and some can store readings over time. They are affordable and resistant to cold and humidity. Refrigerator thermometers are monitoring devices that provide real-time information about the current temperature in a refrigerator’s main compartment or freezing section. […]
Refrigeration mechanics install, maintain, and repair refrigeration equipment in residential and commercial buildings. They use blueprints and schematics, diagnostic equipment, and specialized tools to troubleshoot and repair systems. They may need to hold a license and work weekends and after hours. Safety precautions are necessary due to the hazards involved. A refrigeration mechanic is responsible […]
Refrigerator haiku refers to haiku made with magnetic words on fridge doors or magnets that contain haiku. It originated from the famous English haiku “Haiku are easy, but sometimes they don’t make sense, refrigerator”. Haiku evolved from Japanese poetry and has strict rules, including the use of kigo and kireji. Refrigerator haiku can be humorous […]
