Refrigeration, Yesterday and Today

  REFRIGERATION     The preservation of winter ice, principally for cooling drinks in summer, was practiced from antiquity when ice was stored in insulated caves. Ice cooling was so popular in America that, within a decade of the Revolution, the United States led the world in both the production and consumption of ice. As the use of ice was extended to the preservation of fish, meat, and dairy products, ice production became a major industry in the northern states, and ice was shipped not only to the southern states but to the West Indies and South America. By 1880 the demand in New York City exceeded the capacity of 160 large commercial icehouses on the Hudson River. This industry reached its peak in 1886 when 25 million pounds were “harvested” by cutting lake and river ice with Horse-drawn saws. The advent of mechanical refrigeration in the nineteenth century began a slow decline in the ice trade. The natural ice indu […]


Proper Ice Machine Cleaning and Maintenance

Very few end users fully understand the importance of properly cleaning and sanitizing their ice machines, storage bins, and dispensers. Many don’t even view ice as a food commodity. Yet the quality and safety of every beverage they serve as well as the longevity and power consumption of their equipment depend on the proper maintenance of this equipment. Adding to the problem is that some contractors and technicians may not realize the importance of how to properly perform this task and how to help customers maintain the quality of ice that is being consumed. Many rushes through ice machine cleaning and sanitizing using untrained, entry-level personnel to minimize the cost to their customers. In reality, they are doing their customers a disservice by not being effective at eliminating bacterial growth and scale deposits. Here are some tips that can help your company do a thorough job when cleaning this equipment and help ensure your cus […]

Compressor Checkup Tips

1. General inspection of the compressor. Check compressor shell, piping connections and mounting. To start, check the compressor for discoloration on the head and by the discharge line. This can indicate that the compressor is experiencing excessively high discharge temperatures. If you see blistered paint or a brownish tinge, make note of it. Observe the mounting grommets and make sure they are not split or missing chunks. Ensure the fastening bolts are all present and not loose. On tandem compressor arrangements, make sure the assembly is mounted as per the manufacturer’s requirements or excessive vibration can occur. Look for oil around the piping connections and below the compressor which can indicate a leak. 2. Electrical connections. Check the electrical connectors to ensure that they are tight with no free play. Loose connectors can cause poor voltage resulting in overheating of the connectors and motor. Look for discoloration of […]


Determining Proper Cooling Tower Size

To maximize cooling tower benefits, the appropriate tower size must be selected Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial and commercial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as commercial HVAC systems. As the worldwide market for these applications continues to grow, so does the need to address the issue: How large should a cooling tower be to efficiently handle a specific application. “There are a lot of different applications where you certainly don’t want an undersized cooling tower,” said John Flaherty, president of Delta Cooling Towers. Delta manufactures a line of high-density polyethylene (HDPE) engineered plastic tower models. “For example, if an undersized cooling tower is not producing cold enough water to cool the condenser loop of an office building’s HVAC chiller, t […]
