This paper seeks to explain the reasons why ammonia has been so widely used as a refrigerant for so long, without using buzzwords, jargon or technical terms. The purpose is to provide engineers and technicians
Why is a liquid ammonia bottle cooled before opening it? Why are the proteins in cooked eggs more readily digestible than those in raw eggs? Why would a heat treated enzyme behave differently than a non-heated enzyme? Why does milk have a pH of about 7? Give two reasons why you should...
Meaning: This corn is grown with so much anhydrous ammonia, a fertilizer that’s also an ingredient in methamphetamine (“You ever seen ‘Breaking Bad?’” he asked), that you could compare it to an illicit drug. He sees this as somehow unnatural, which is a claim Niemeyer and others di...
In addition, how does your example use this this law? State the formula and measurement unit that is commonly used. Determine the value of the specified properties at each of the following conditions. (a) For ammonia at p =8 bar a...
It is true that LEDs also degrade in light intensity. But that’s usually after it achieves its lifespan. Once a fixture has been used for the specified lifetime period, some of its diodes often start to fail. And with each failure causes a reduction in the amount of light produced by...
1876 年 Carl Von Linde 首次在蒸汽压缩机中采用氨作为制冷剂。CO2 和 SO2 等其他制冷剂直到上世纪 20 年代才得到广泛应用。 20 世纪 20 年代,氯氟烃在美国的发展使天平转向了这种新型制冷剂。与当时采用的其他所有制冷剂相比,氯氟烃可视为一种无害而且非常稳定的化学物质。但当时无法预见大量使用此制冷剂对外部环...
Ammonia (NH3) is one of the most common industrial chemicals, used widely as a refrigeration gas throughout the food and beverage industry as it offers superior refrigerant advantages. Not only is ammonia abundant and extremely efficient in refrigeration systems, requiring less energy per BTU, its...
"Mechanical Integrity Inspection" is perhaps the most ambiguous term used in the ammonia refrigeration industry. This paper provides a common sense definition of the term and describes a simple structured approach to such inspections that answers all of the basic questions surrounding this issue: What...
