Snowmaking is the production of snow by forcing water and pressurized air through a “snow gun,” also known as a “snow cannon.” Snowmaking is mainly used at ski resorts to supplement natural snow. This allows ski resorts to improve the reliability of their snow cover and to extend their ski seasons from late autumn to early spring. Indoor ski slopes often use snowmaking. They can generally do so year-round as they have a climate-controlled environment. The use of snowmaking machines is becoming increasingly common as changing weather patterns and the rising popularity of indoor ski resorts create a demand for snow beyond that which is provided by nature. Snowmaking machines have addressed the shortage in the supply of snow, however, there are significant environmental and cultural costs associated with the artificial production of snow. According to the European Environment Agency, the length of snow seasons in th […]

What is Refrigeration? Refrigeration deals with the cooling of bodies or fluids to temperatures lower than those of surroundings. This involves the absorption of heat at a lower temperature and rejection to a higher temperature of the surroundings.   In olden days, the main purpose of refrigeration was to produce ice, which was used for cooling beverages, food preservation, and refrigerated transport, etc. Nowadays refrigeration and air conditioning find so many applications that they have become very essential for mankind, and without refrigeration and air conditioning, the basic fabric of the society will be adversely affected. Refrigeration and air conditioning are generally treated in a single subject due to the fact that one of the most important applications of refrigeration is in cooling and dehumidification as required for summer air conditioning. Of course, refrigeration is required for many applications other than air con […]

Technology, and market desire influence trends Demand is changing the landscape of coils and condensers in the HVAC industry. Efficiency demands are on the rise, refrigerant demands are changing, and market demands are adjusting to a global cooling market and its varying technology. It is in this environment that coils and condensers are progressing.   COIL CHANGES Some of the major coil changes that have occurred over the last decade have come from solving a problem. For instance, many manufacturers have added an epoxy coating to reduce the occurrence of the odor issue known as dirty sock syndrome. Trane Hyperion Air Handler. PROBLEM-SOLVING: Major coil changes that have occurred over the last decade have come from solving a problem, like factory-issued, epoxy-coated coils — found in the Trane® Hyperion air handlers — that reduce the occurrence of the odor issue known as dirty sock syndrome. “Assuring the product is installed with […]

Food products require a lot of care. The food products should be stored with proper care. It is important that there is adequate cold storage for the food. All of the food businesses have refrigeration appliances to make sure that their food products are safe and fresh for use. The large food businesses need to have large stocks of food products at all times. Food products can only be stored if there are heavy duty refrigeration appliances available. To make sure that the food products are kept fresh, they need to be stored at the temperature of +68 C and +8 C for as little time as possible. The decreased temperature will result in decreased growth of the bacteria. The food is spoiled by the growth of the microorganisms such as the bacteria. Blast chillers: The food products can be frozen and chilled by using the freezers or the blast chillers. The blast chilling is an excellent way of making sure that the food products are not kept at […]

In 1842 John Gorrie created a system capable of refrigerating water to produce ice. Although it was a commercial failure, it inspired scientists and inventors around the world. France’s Ferdinand Carre was one of the inspired and he created an ice producing system that was simpler and smaller than that of Gorrie. During the Civil War, cities such as New Orleans could no longer get ice from New England via the coastal ice trade. Carre’s refrigeration system became the solution to New Orleans ice problems and by 1865 the city had three of Carre’s machines.[13] In 1867, in San Antonio, Texas, a French immigrant named Andrew Muhl built an ice-making machine to help service the expanding beef industry before moving it to Waco in 1871. In 1873, the patent for this machine was contracted by the Columbus Iron Works, a company acquired by the W.C. Bradley Co., which went on to produce the first commercial ice-makers in the US. By the 1870s brewe […]

For food and beverage processing facilities, the industrial refrigeration system is key to operations. It can also be the key investment and factor in a facility’s operational efficiency and ongoing costs for maintenance and energy use. Being environmentally responsible is becoming more important for industries across the board, and in recent years, the field of industrial refrigeration engineering has seen an array of advances in more efficient equipment and more sustainable refrigerants. However, in much of the industry, engineering practices that have been the industry standard for years are slowing the adoption and use of these new technologies. By employing older, typical engineering approaches in the design of new systems, production facilities are not only unnecessarily wasting energy and resources, which also impacts the environment, but these businesses that rely on refrigeration are wasting their cold hard cash. Table 1. Assum […]

Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners. When put under pressure, plastic crystals of neopentylglycol yield huge cooling effects—enough that they are competitive with conventional coolants. In addition, the material is inexpensive, widely available and functions at close to room temperature. Details are published in the journal Nature Communications. The gases currently used in the vast majority of refrigerators and air conditioners —hydrofluorocarbons and hydrocarbons (HFCs and HCs)—are toxic and flammable. When they leak into the air, they also contribute to global warming. “Refrigerators and air conditioners based on HFCs and HCs are also relatively inefficient,” said Dr. Xavier Moya, from the University of Cambridge, who led the research with Professor Josep Lluís Tamarit, from the Univer […]
