Refrigerants

Different substances come along to satisfy different requirements and sometimes only partially (Arora, 2001, p. 140). apart from library and internet sources, interviews have been conducted to add more cultivation on the advantages and disadvantages of alternative refrigerants. The interviewees be current engineers and have a perspective on the orbit of refrigeration and air-conditioning. This paper intends to inquire the best alternative refrigerants ground on the different properties and characteristics of for each one known refrigerant and the opportunities and challenges they pass away to society. Ammonia has been at the forefront of advancement in refrigeration technology, making it necessary to the development of industrial plants (Arora, 2001). There are different properties and chara cteristics of ammonia water that determines ! its effectiveness as a refrigerant....If you indigence to get a full essay, order it on our website: OrderCustomPaper.com
