Magnetic cooling is a promising new refrigeration technology boasting several advantages – ranging from lower energy consumption to eliminating the use of hazardous fluids – that combine to make it a much more environmentally friendly option than today’s standard fluid-compression form of refrigeration. One novel magnetic cooling approach, developed by a team of Canadian-Bulgarian researchers, relies on solid magnetic substances called magnetocaloric materials to act as the refrigerant in miniaturized magnetic refrigerators. As the team describes in the journal Applied Physics Letters, from AIP Publishing, these materials are the key to the development of a “green” cooling technology whose efficiency is able to scale directly with the generated magnetocaloric effect. The magnetocaloric effect is “the thermal response of a magnetic material to the change of an external magnetic field, which manifests as a change i […]

According to a new report from Zion Market Research, global demand for commercial refrigeration equipment was valued at USD 36.63 billion in 2015 and is expected to generate revenue of $61 billion by the end of 2021, up from a value of $36.6 billion in 2015 for a compound annual growth rate of slightly above 9.0 percent between 2016 and 2021. Commercial refrigeration equipment in the report is defined as equipment used for refrigeration in food and beverage industry, for food storage and merchandising purposes by the food wholesale industry, such as supermarkets, specialty food stores, grocery stores, and convenience stores. A commercial refrigerator is a free-standing part of the equipment that gives cold storage for a commercial kitchen. Some of the different types of commercial refrigeration include reach-in refrigerators and freezers, walk-in refrigerators and freezers, under counter refrigerators, refrigerated merchandisers, bar re […]

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids. Types of compressors The main and important types of gas compressors are illustrated and discussed below:   Positive displacement Positive displacement compressor means a system which compresses the air by the displacement of a mechanical linkage reducing the volume (since the reduction in volume due to a piston in thermodynamics is considered as the positive displacement of the piston).   Reciprocating compressors Reciprocating compressors use pistons driven b […]

Thermostatic expansion valves (TXVs) are one of the most common types of adjustable orifice throttling device in air conditioning and refrigeration systems worldwide. They earned this place by being both efficient and affordable. But how do TXVs compare to other throttling devices? Fixed orifice devices like capillary tubes or pistons are cheaper and electronic expansion valves (EEVs) offer greater superheat control across a large load range, so why are TXVs so popular? Fixed Versus fixed orifices: orifice devices are ideal throttling devices if conditions never change. If the load on the system is constant and the ambient temperature remains steady, then a simple capillary tube or piston would be preferable to an adjustable orifice device like a TXV. However, outside of a laboratory, static conditions are simply not realistic. Seasonal temperature changes have a profound effect on system performance, as does increaseing the heat load i […]

For the commercial food service and related industries – which rely daily on large quantities of ice for food displays, safety, preparation, beverages and more – the ability to reliably and cost-effectively produce ice can have an impact on a business’ operation. Between 2005 and 2010, Manitowoc Ice, Inc., the Wisconsin-based manufacturer of commercial ice machines, became interested in taking their product portfolio one step further and turned to Danfoss with the idea to design an ice machine that would improve customers’ sustainability efforts by operating on natural refrigerants. The collaboration with Danfoss led to the development of two new models within Manitowoc’s Indigo Series and two Q-Series under-counter units that are cooled by R290, or propane, which Manitowoc introduced in mid-2011. The use of an environmentally friendly hydrocarbon refrigerant enables Manitowoc to offer customers a product that has zero ozone depletion p […]

The Dog is the eleventh of all zodiac animals. According to one myth, the Jade Emperor said the order would be decided by the order in which they arrived to his party. Monkey, Rooster and Dog were in another country, helping a god defeat evil spirits. After, they set off to the party together. Because they arrived at the same time, the Jade Emperor went by the order they met the god in the other country. Thus, Dog became eleventh. The Dog is also associated with the Earthly Branch (地支—dì zhī) xū (戌), and the hours 7–9 in the evening. In the terms of yin and yang (阴阳—yīn yáng), the Dog is yang. In China, it is still popular to name dogs Wàng Cái (旺财). It means “prosperous wealth” and comes from dogs’ barking sounds (旺旺—wàng wàng). Honest and loyal, Dogs are the truest friends and most reliable partner. Recent years of the Dog are: 1934, 1946, 1958, 1970, 1982, 1994, 2006, 2018 Bàinián and kowtow It can be said that Chinese culture is bas […]
